How to charge a laptop using an external battery. Powering a laptop in the field. Universal external battery manufactured by Hyper

Sometimes you need to take a laptop on a long trip. However, a situation often arises when the charger fails or there is no source nearby alternating current. In this case, the question arises: “How to charge a laptop without charging?”

What to do if the charger fails on the road?

If the charger breaks down at the wrong time, you can try to fix the adapter yourself. You need to check the condition of the cable that connects to the laptop. In most cases, it deteriorates due to improper use or, for example, when the battery is not latched completely.

You can try to disassemble the charger. It happens that one or more wires come off. In other cases, when the charger does not work, it is necessary to either replace it or use unconventional means of recharging the battery.

Features of using solar panels for batteries

If you spend most of your time outdoors, and you need a laptop for work or entertainment, then one of the ways to extend the working time laptop computer from a battery - purchase a solar battery. It connects directly to and allows you to recycle energy sunlight into electricity.

In general, there are 2 types of laptop charging: stations designed to maintain functionality large quantities electronic equipment, and portable mini-batteries with low power. The first option is not suitable for going outdoors: the huge dimensions and complexity of the installation do not allow you to quickly stop the work in case of precipitation.

The main advantage of this charging method is that it can extend the operating time by a couple of hours (depending on the power). A standard portable one has a voltage of 19 V. However, it is important to consider that this indicator can only be obtained in clear, cloudless weather. This power is enough to charge a laptop battery.

The only drawback of a solar battery is the inability to work on a computer while charging. This is because maximum voltage at 19 V - the value is not constant. Through certain time the battery will gradually lose its energy characteristics. Thus, when thinking about the question of how to charge a laptop without charging, you should remember that buying the above-mentioned device will only be beneficial if you are going to be in a sunny place for a long period of time.

Extending laptop life using an external battery

Another way to charge a laptop without a charger is to purchase this portable equipment, which allows you to increase the operating time of your computer by several hours. In most cases standard laptop can function without recharging for about 2 hours. When purchasing an external battery, this period can be increased by approximately 2 times.

Answering the question “how to charge a laptop without a charger”, we note that on this moment exists big choice external adapters, differing both in size and in the amount of energy required to operate without a network.

Another advantage of this charging method is that the external battery comes with branches that allow you to charge your smartphone, digital camera, tablet. As for the disadvantages, these include the size of the battery. However, in the online store you can choose a battery with a small charge capacity that fits in a hiking bag or backpack.

Thus, charging a laptop using external battery can be carried out anywhere, regardless of weather conditions(which cannot be said about batteries that use solar energy) and the location of the computer.

Charging a laptop in a car

If you can't do without a laptop in long trip, there is a need to recharge it. Even if the charger functions normally, most cars do not have an outlet to keep the device in working condition (expensive foreign cars are an exception).

There is an option - to purchase a portable 17 V inverter. It is important to note that in most electronics stores you can choose a charger for any computer model. When solving the question “how to charge a laptop without charging”, you should know that this method of recharging a laptop is only possible when the car’s ignition is on. Otherwise, there is a risk of draining the battery due to high energy consumption.

These methods of charging a dead battery are suitable primarily for those who do not understand electronics and cannot independently diagnose a malfunction in a failed charger. Moreover, if there is no nearby service center servicing your laptop model, the considered options can be considered the only way out in a situation where there is a need to urgently recharge a laptop or tablet.

In addition, using an external battery with a large charge capacity will make it possible to recharge not only a discharged computer, but also other types of digital equipment- camera, video camera, tablet or smartphone. The charging method you choose depends on your specific situation and your financial opportunities (solar battery will cost an order of magnitude more than external battery and car adapter combined).

Conclusion

Thus, if a family trip or business trip does not allow you to do without a computer, and the charger is out of order, you can use one of the considered methods to keep the battery working. In general, the answer to the question of how to charge a laptop without charging is extremely simple: using a portable external battery, solar battery or car adapter will help solve the problem and provide the opportunity to use the PC at the right time.

Choosing an external battery for a laptop

For some modern people the laptop is an integral companion with which they never part. They take a laptop with them on a business trip, on vacation, and to any other place so that they can always use it. For some it is a source of entertainment, but for others mobile office in which they work on the road. Both of them have one problem in common. The laptop battery runs out and users are left without their companion. On the road, it is quite difficult to find an outlet to connect to. In such cases, an external laptop battery will help out. Today we will talk about what characteristics should be taken into account when choosing portable battery for laptop. We will also consider several models of external rechargeable batteries.

There are a number of characteristics that must be taken into account when purchasing an external battery for a laptop.


Some users choose extra battery for laptop appearance and the materials used. IN best case scenario Capacity is taken into account. But this is the wrong approach. When choosing an external battery, you should consider the following parameters:
  • Battery capacity and voltage;
  • Charge current;
  • Set of interfaces;
  • Method of charging the Power Bank itself;
  • Materials and design;
  • Additional "chips".

Below these properties of portable batteries are discussed in more detail.

Capacitance and voltage

It is no coincidence that these quantities are considered in conjunction. Capacity, as you know, is expressed in ampere-hour or milliamp-hour. All other things being equal, we can say that the larger the capacity of the external battery, the more laptop will work in offline mode. But one thing to consider important point. Most laptop models require a power supply voltage of 19 volts. Less common are laptops that operate on 12 volts.

Manufacturers, in order to attract attention to their product, like to remain silent about the voltage of battery cells. On the contrary, the capacity is written in large letters on the packaging. But, for example, a capacity of 20 Ah for a 12 volt battery and for a 19 volt battery are different things. In the first case, the stored energy is 240 watt-hours, and in the second ─ 380.

The stored energy is calculated using the formula:

1 watt-hour = 1 ampere-hour * 1 volt

If the voltage of the external battery cells is less than the laptop battery rating, then charging is performed through a boost circuit. This leads to big losses. As a result, out of 20 ampere-hour, barely half will “migrate” to the laptop battery. Therefore, when comparing various models For portable batteries, focus on the stored energy, measured in watt-hours. Read more at the given link.

As for the size of the capacity, it must be selected depending on the laptop battery. For example, for a laptop with a 4.7 Ah battery, it is better to take an external battery with a capacity of 10 Ah or more. This will ensure that you charge it at least once on the road. If the device will also be used to charge a phone, tablet, player, then choose according to the total capacity of their batteries multiplied by 2.

Charge current strength

This is another one important parameter, since the charging speed of the laptop battery will directly depend on it. On the market you can find models that have several USB ports with different current strengths. These are “harvesters” that allow you to charge smartphones, tablets and other gadgets. To charge the laptop you must have USB interface with a current output of at least 2.5 amperes. With a lower value, the charge will “flow” for a long time. If you plan to operate from an external battery, then the current must be no less than that consumed by a running laptop.

Set of interfaces and adapters

The choice of interfaces and adapters will determine which devices you can charge with it. As a rule, an external battery for a laptop is equipped with big amount adapters. But when purchasing, be sure to check whether there are adapters for your laptop. Eg, Apple laptops are charged through their own specific connector. Therefore, an appropriate adapter will be required. So, pay close attention to the packaging of your portable laptop battery.

Power Bank Charging Method

Also an important parameter when choosing an external battery. The device must have a power connector for charging from the network. Additionally there may be a USB port, but this is optional. If there is no power connector, then charging an external battery will turn into a painful procedure that will last for many hours.

Additional features

If it's not enough for you standard features, you can search for devices with different additional features. For example, it could be a flashlight, a solar panel for charging, a point Wi-Fi access, USB hub etc. All these “chips” will increase the price of the battery. Therefore, first of all, make sure that you are satisfied with the main characteristics, and then add more, if you have enough money.

Examples of external battery packs

Some models will be discussed below power bank for laptops from various manufacturers.

This external laptop battery comes with a pretty decent set of adapters.

The package included:

  • Battery;
  • Adapters for various devices;
  • Network adapter;
  • Cables for charging the device and USB;
  • User manual.

A good portable battery, suitable for charging laptops and many other gadgets. The battery has dimensions of 160 by 95 by 25 millimeters. Weight approximately 400 grams. The body is made of two parts: a large black one and a small white one. There are rubberized inserts on the sides. The manufacturer made them in bright orange color.

There is a digital display, which shows the charge level of the external battery. In addition, there is an indication of the charging type (12 or 19 volts). There is a power button next to the display. And also the company logo.

The interfaces are on the bottom plane. This is the charging connector, USB port, connector for charging laptops 12 or 19 volts. Adapters for different laptops are located on a special plate. All of them are marked depending on the standard size. There are also adapters for other gadgets, including models from Apple.

Main parameters:

  • Battery type ─ lithium ion;
  • Capacity ─ 12 Ah;
  • Charging connector ─ DC 13 volts, 1 ampere;
  • Charging port No. 1 ─ DC 5 volts, 1 ampere (USB);
  • Charging port No. 2 ─ DC 12 volts, 3 amps / 19 volts, 2.5 amps;
  • Service life ─ 500 charge-discharge cycles;
  • Charging the external battery lasts 3-4 hours;
  • Operating temperature from 0 to +45 degrees Celsius.

The capacity of this external battery is 23000 mAh. Dimensions 222 by 126 by 21 mm, and weight approximately 650 grams. In general, a rather big battery. It is reported that the plastic used is impact-resistant. The coating is pleasant to the touch, and there are glossy orange inserts on the sides.

The iconBIT FTB23000S portable battery can be carried in a laptop bag or backpack. This device is still a bit big and heavy for a pocket. There is a solar panel on the top side of the battery. Device charge level shows 4 LED indicator. In addition, the indication shows activity solar panel and output voltage value. The battery power button, in addition to its main function, is used to activate the flashlight and control the charge.

There is an output voltage switch on the side. Possible values ​​are 12, 16, 19 volts. The current in these three modes is 3 amperes. This is enough for most modern laptops. For those gadgets that “eat” less, there is a USB interface with a charging current of 2.1 amperes. Included are:

  • 10 adapters for laptops and video cameras;
  • micro USB cable;
  • adapters for Nokia phones;
  • connectors for Apple products(iPhone 4, iPad, iPod, iPhone 5, etc.).

Sometimes you need to work on your laptop for a couple of extra hours away from the outlet, and an external laptop battery helps with this. There are many external batteries and mobile chargers, but most of them are not suitable for laptops. Typically, a laptop requires a power supply voltage of 19 V, less often 12 V, and mobile chargers for phones and tablets produce a voltage of 5 V, so you should look for a 'power bank for a laptop' or 'portable battery for a laptop'.

In addition to matching the output voltage of the battery and the supply voltage of the laptop, it is necessary that the output current of the charger is not lower than the current consumed by the laptop.

The next factor that needs to be taken into account is the connectors; the charging plug must match the laptop socket, and the polarity of the power supply must also match. Usually there is a ‘-’ power supply on the external contact, and a ‘+’ on the internal one. Often external batteries come with a bunch of adapters for Various types nests, but this does not give an absolute guarantee. So check the availability of the required plug before purchasing.

Finally, when choosing an external battery for a laptop, you should pay attention to its capacity. The larger the battery capacity, the longer the laptop will run on such a battery. Battery capacity can be measured either in milliAmpere hours (mAh) or in Watt hours (Wh), I recommend comparing the capacity in Watt hours because the capacity in milliAmpere hours depends on the battery voltage and the comparison will be correct only if the voltages are equal both batteries.

By the way, some battery manufacturers are cunning and indicate the capacity only in mAh and take the voltage equal to 3.6V. An honest manufacturer will indicate a capacity of 4000 mAh 10.8 V, and a dishonest one 12000 mAh; in fact, both batteries will have a capacity of 43.2 Wh, and it will seem to us that the second one has 3 times the capacity.

Well, the brand of the battery also matters: how long the battery will last, how honest the capacity is, thoughtfulness and ease of use. You should look for information on specific external batteries on specialized forums.

Actually, adding the price factor to the above factors, I started searching, found and bought the cheapest one found, an external battery for a laptop: external battery DF Charger-01 12000mAh for laptops, tablets and smartphones.

It comes in transparent packaging. What's included:

  • external battery (not light weight);
  • AC charger 15 V, 1A;
  • output cable;
  • set of adapters for different types laptops and mobile phones.

Let's start with the fact that the adapter Asus eee 1025CE was not included in the kit and I had to make the cable myself.
Everything went well with other existing laptops, we were also pleased with the 12 V which can charge the tablet. We can only talk about 5 V as a pleasant bonus because I wouldn’t carry such a huge thing for a mobile phone.

At the end there are three connectors: input and output round and full-size USB. 15 V is supplied to the input from the supplied charging block power supply, the output round may contain either 12 V or 19 V.

On the front panel there is a charge indicator that displays the degree of charge from 0 to 99%, next to it there is a power/mode selection button and two green and blue LEDs.

To turn on the portable battery, you need to press the button, after which the indicator will display the battery charge level, 12 V will be supplied to the output of the device and light up green indicator. In order to obtain a voltage of 19 V at the battery output, you need to press the button again. To avoid accidental voltage increases, the battery does not respond to pressure immediately, but after a long press. Instead of the green LED, the blue LED lights up and 19 V is supplied to the output.
A long press of the same button will turn it off, but you can simply turn off the load and the battery will turn off by itself.

Attention!!! When powering a 12 V load, be careful when switching modes, as 19 V entering the 12 V input of the device may damage it.

The overall impressions of charging are positive; it copes with its functions. But there is also a decent fly in the ointment:
It takes a long time to charge from the weak supplied 15 V charger; it would be better if it were charged from a standard laptop 19 V charger.

The size of the charger and the weight (400g) are too big: mobile phone chargers with this capacity are two times smaller and lighter.

Of course, the plus of charging is that it can simultaneously charge a laptop through the main output and mobile phone via USB, but the charging current via USB is scanty. Although the stated current is 1 A, my Samsung took less than 0.5 A. Apparently the data contacts inside the charger are just dangling in the air and the phone does not understand that you can get 1A from the charger.

I will give the data from the packaging:

The manufacturer is cunning with the capacity: 12000 mAh is clearly indicated for 3.6 V. It does not prudently write about voltage and Wh.

Here is the instruction manual that was included in the kit:

Precautionary measures.

Delivery set and characteristics.

Appearance.

A set of replacement adapters and charging instructions.

Additional Information.


I describe my personal experience Powering the laptop from external batteries. Getting ready to move to live in nature, I was puzzled by solving the problem of powering my laptop from a battery. Having rummaged through the forums, I didn’t find anything simple and accessible. Everyone suggested either a homemade adapter for power supply from a car generator, which is very difficult to assemble. Or ready-made solutions, such as laptop auto adapters and 12 volt to 220 volt current converters to use a regular laptop power supply. But all these adapters cost money, and I didn’t have the opportunity to buy something ready-made.

Here's how I got out of the situation. The laptop is powered by 19 volts, I took and purchased 3 batteries from UPS at 6 volts 4.5A. I connected them in series and got 19 volts. I cut off the wire from the power supply, the one from the unit to the laptop and connected it to the batteries, observing the plus or minus. Next, I took the battery out of the laptop and connected the power cord. I turned it on and the laptop started working.

Attention - if you power the laptop from batteries, then its own battery must be removed, otherwise the laptop will burn out. I'll explain why. Standard block The power supply provides a certain current, for example 4A, and its battery consumes all these 4A. And if you power it from external batteries, then the battery of the laptop itself will charge everything that is given to it, and external batteries can produce tens of Amperes. With such a charging current, the hardware of the laptop simply cannot withstand it and the built-in power supply of the laptop will burn out.

In order to not only power, but also charge the laptop from external batteries, you need to install a resistor that will limit charging current. For example, if your laptop is powered by 19 volts 4A, then you need to install a 4A resistor. But I know that this option also causes some difficulties, since you need to find the right resistor. There is an even simpler option: instead of a current-limiting resistor, you just need to put a car light bulb on required quantity Ampere.

For example, if your laptop consumes 4 amps, then you need to install a 4 amp light bulb. It will work like a resistor, that is, passing only 4 amperes through itself, while it itself will consume the same amount. Yes, with this scheme, the electricity consumption from external batteries will be 2 times greater, but this will allow you to charge the internal battery of the laptop.

And so, look at the picture, in the first image the laptop is powered directly from 3 6-volt batteries. With this scheme, you must remove the internal battery, otherwise it will burn out. indoor unit laptop power supply.

In Figure “2” the laptop is powered and charged through a resistor. Turning on a resistor or light bulb will not only power, but also charge the built-up laptop battery.

All the above methods I tested it on mine acer netbook, and it still works, I’m writing this article from it. Please note that for power supply I use 3 6.4 volt batteries, this is when serial connection gives 19 volts. There are also laptops that are powered by 12…..16 volts. These laptops can be powered directly from 12 volts (auto battery), just remember to remove the internal battery. If you want to charge your laptop, then charge it through a resistor or a light bulb.

Another way to power a laptop if the laptop battery is dead

Power supply of the laptop from 12 volts, from the battery

The laptop's original battery failed, or rather it worked, but the charge lasted for about 20 minutes at most. And one fine day our electricity was cut off for 2 days, and I needed to correspond on the Internet. And I decided not to wait until the electricity was turned on, and to disassemble the built-in battery of the laptop, it was of no use anyway. There were 4 elements inside, the battery says 14.8 volts, which means each element is 3.7 volts.

Inside there are 2 main wires that are soldered to the ends of the element assembly, and several wires that are soldered between the elements. We need those 2 thick wires. which are on the sides of the element assembly. These wires are plus and minus for power, I connected a 12-volt battery to them and that’s it, we insert the empty battery case into its place and turn on the laptop, everything works.

By the way, depending on the model, the laptop may swear at the power supply and write that the battery is low, but don’t worry, this is because an ordinary car mobile battery gives 12 volts, not 14 volts, which is why the laptop thinks that its battery is low, but it does not turn off and works normally until the battery is actually discharged.

This option is only suitable for 11.1 or 14.8 volt batteries. But these are emergency options, and it is better to use devices designed for this.

An external mobile battery or power bank for a laptop can become the best option to increase the operating time of your laptop computer.

With an average capacity of built-in batteries of 3000–6000 mAh, the average duration of use of the gadget does not exceed 3–5 hours.

A good power bank will increase this time by at least three times, allowing you to work on your laptop even when complete absence electricity for several days.

In order to figure out which model is best to purchase today, you should consider several important factors, starting from capacity, ending with functionality and price.

Types of power banks

A modern power bank is a universal battery suitable for several types of devices at once.

In fact, if you have a suitable adapter, you can charge any gadget from a power bank - from a mobile watch and player to a tablet and laptop.

For ease of use, the array with batteries is enclosed in a housing with one or several outputs (USB and microUSB).

Different models of external batteries differ in the following parameters:

  • power ranging from 1000–50000 mAh;
  • number of connectors;
  • presence of a charge indicator;
  • type of battery (lithium-ion or lithium-polymer). From regular batteries they are distinguished by a long service life and maximum energy intensity;
  • size and weight, which usually depend on power;
  • design;
  • device manufacturer.

Standard model external source power supply is a small rectangle resembling an mp3 player or portable HDD.

They are charged from the network (using a regular charger), from the USB connector of a PC, and even from the laptop whose resource they will be used to increase.

Features of choosing a battery

The main factors when choosing mobile external batteries are size, capacity and manufacturer.

The next most important point is the design of the device and its durability.

If the device will be used to charge several devices, you should pay attention to its functionality - the presence of a charge indicator and several inputs.

Characteristics

The main characteristic device, which is worth paying attention to is the name of the manufacturer.

Popular brands PowerPlant, Drobak and Xiaomi have entered this segment, producing powerful batteries, which are suitable for any type of mobile electronics, including laptops.

Little-known manufacturers are not as reliable, and their stated battery capacity may actually be lower.

The next point is the degree of protection of the external battery from dust, moisture and shock.

And, if the impact resistance is not the best important characteristic, then preventing liquid and dust particles from getting inside can be called an important option.

All functional models well-known brands have such protection - not to such an extent that you can dive with them, but enough to be in a room with high humidity.

Fully protected, including from falling, the external battery option can usually be recognized by the orange or dark red design of the case.

Another quite important characteristic of the device is its capacity. The larger it is, the longer the laptop will work without recharging from the mains.

Batteries with minimal capacity are not suitable for use to extend the charge of a laptop.

To do this, you should choose models with 20,000–30,000 mAh or more.

A capacity of 20 thousand mAh is already enough to increase the operating time of an average laptop PC by 3 times, 30 thousand is enough for a fivefold increase.

Although, if mobility plays the main role, you should pay attention to devices with a capacity of no more than 10,000 mAh - they are also quite productive, weigh no more than 200-300 g and fit in the pocket of a laptop bag.

Advice: don't chase after large capacity, searching for batteries with 40-50 thousand mAh capacity - most often these are fakes with lower parameters.

Additional parameter What requires attention from female and youth users is the design of the device.

Often such equipment is not just made in the usual discreet color, but can have an original and eye-catching appearance.

When choosing a case material - plastic or metal - it is worth noting that modern plastic is often not much inferior in strength to aluminum.

Moreover, many new models of portable chargers are encased in a polymer shell, having no less wear resistance.

At the same time, they are more pleasant to the touch than metal options.

Functionality

Functionality may differ markedly between different models. For example, some power banks are capable of charging no more than one laptop at a time.

With the help of others, you can increase the operating time of your laptop PC, tablet, smartphone, or several laptops at the same time.

If the number of charging connectors reaches 3 or even 4, additional device For example, a small USB lamp can be used for connection.

The connectors differ in current strength, which determines the charging time. For a tablet or smartphone, a 1 or 2 A USB port is sufficient.

The laptop may require a 3.2A connector that can charge its main battery faster.

Additional benefit The device can become a digital indicator, which shows how many percent of the charge is left.

Whereas the complete set of built-in LED lamp will also ensure the use of a power bank as a temporary source of lighting, and one that lasts much longer than even conventional hand-held flashlights.

Compatibility of models produced in the last few years may not be considered. All of them are suitable for charging any gadget.

Moreover, some power banks They are supplied with adapter cords designed for most connector options - from USB and microUSB to inputs for various laptop models.

Advice: When charging a laptop, the second battery must be connected to the power supply. Because if you connect them to a USB connector, the battery will not charge the laptop computer, but, on the contrary, will be recharged from it.

The most powerful

The most powerful of all consumer-trusted portable chargers is the PowerPlant K2 50000.

This battery can replace the batteries of ten laptops and 15 medium-sized tablets at once.

The complete set of adapters allows you to use it specifically for charging laptop computers.

Security options include protection from short circuit, and from spontaneous discharge, and from overheating.

Technical specifications:

  • capacity: 50000 mAh;
  • adapters included: to Toshiba laptops, Sony, Acer, Samsung, Dell, Lenovo and HP;
  • price: from 12,000 rub.

Best solar powered option

A good option for a power bank for a laptop would be the KS-303 model, which can be charged not only from electrical network, but also from the sun.

This will increase the already decent battery capacity of 20,000 mAh, sufficient for many hours of operation of the laptop.

Among additional features devices - protection of connectors from moisture and rubberized housing.

Gadget characteristics:

  • capacity: 20000 mAh;
  • features: 220 mA solar battery;
  • cost: from 3000 rub.
