How to charge a laptop without charging? What should I do if my laptop charger is unavailable or not working? How to make an external battery from an old laptop

As a laptop user, you have probably encountered situations in which you need to charge your laptop battery without using the laptop itself. In this article, we will reveal to you methods on how you can recharge a laptop battery without the name of the corresponding device.

To begin with, it is worth noting such a fact as the universality of this instruction in terms of application of recommendations. Thus, after a detailed study of the material we have presented, you will be able not only to charge the laptop battery, but also to do the same with some other portable devices.

Not all methods discussed are universal!

Those battery charging methods that were not provided for by the technical specifications of the laptop and battery may well lead to failure of the component being charged. In this regard, when following the instructions, you should exercise maximum caution so as not to damage the battery.

In some cases, not only the energy cell may be at risk, but also the laptop itself in which the battery is planned to be used in the future.

Moving on to the main material, be aware that in the process of recharging the battery without a laptop, you will need additional parts. Some of the required components are not so easy to obtain, so you should choose the most suitable method according to your capabilities.

Method 1: Using a different laptop

This is a completely obvious method for any user, but it would be wrong not to mention it, given the essence of the topic being discussed. Moreover, in most cases, this method is the easiest way to charge the battery of a laptop computer.

You should not have any problems with the charging process; you just need to install the battery in another laptop and connect it to power from the mains. The model of the other laptop must match the device from which you want to recharge the battery.

The main disadvantage of this method is that neither the laptop nor the battery are designed for repeated replacement of the energy cell. Because of this, after this kind of recharging, side difficulties are quite possible, such as the computer refusing to charge the battery.

Method 2: Using a new battery

As you know, each battery purchased has a maximum charge level and is quite suitable for operation in accordance with the specification and amount of load from the laptop. As a result of the above, you can purchase a new battery and use it for your own purposes.

Of course, the method is also quite predictable and far from the cheapest, but it is still better to bypass more radical measures by any means. In addition, as mentioned earlier, there may be unpleasant consequences that could entail the need to purchase a new energy cell.

Method 3: Use a power adapter

This method, which is also the most radical, is the only way to charge the battery without a laptop. To use these instructions, you will need to prepare in advance a number of special tools, which can be purchased at almost any electronics store.

In general, the list of necessary tools cannot be called modest:

Power adapter (above battery voltage);
Multimeter;
Several wires (preferably copper).

In addition to the above, auxiliary parts such as electrical tape or a soldering iron will also be useful in order to somewhat secure and stabilize the process of connecting the external adapter.

Having prepared the parts we have mentioned, you can begin the initial measures before charging the battery.

Take the laptop battery and carefully inspect the contacts.

Literally all modern batteries are equipped with a complex voltage distribution system, which is why the standard number of terminals is quite large and can easily reach 4-7 or more.

Occasionally, contacts on such energy cells have marks indicating the polarity of a particular segment.

If you do not find any visible marks from the manufacturer, carefully examine the specifications on the battery. Often information about the ownership of a particular terminal is placed there.

In the absence of even such prompts, use a previously prepared multimeter, one by one checking the contacts for the value «+» And «-» .

It happens that the terminals themselves are protected by small plastic walls, which become a problem for accessing the multimeter plugs. This can be solved by using straightened paper clips or needles.

Often the segments needed are the leftmost and rightmost contact.

To calculate the required segments using a multimeter, use a power adapter!

After you have found the necessary terminals on the laptop battery, you need to connect these contacts with the wiring previously specified in the list of requirements.

Having finished with the preparatory manipulations, further actions can essentially be divided into two separate methods, depending on what specific power adapter you have.

In the first case, one way or another you will need not the laptop itself, but at least its standard power adapter. At the same time, it can easily be replaced with any other similar power supply from a laptop, taking into account the technical requirements of a lithium-ion battery.

In addition, you must also get a socket that matches the plug of the power adapter you are using. However, it is quite possible to do without this, using an accurate knowledge of the pinout of contacts and a soldering iron.

The pinout remains unchanged - in the center «+» , on the edge «-» .

At this point, actions from both possible methods go to the same list of instructions. Now we can shed light on another option for connecting the battery.

The second method, unlike the first, does not require you to use a specific laptop power supply. Moreover, the technique is rather complementary, since literally the same thing can be done using a laptop adapter.

You will likely experience some differences in your actions!

This is where the clarification of the second method ends and all that remains is to make a few comments, mostly related to safety rules. The following comments apply equally to both described methods, taking into account the specifics of your specific charging case.

In addition to all that has been said, it is also quite important to keep the multimeter connected to the created structure so that the voltage is always under your control. The most ideal charging indicator is a smoothly increasing voltage, finally slightly greater than the final battery voltage.

Information about the outgoing battery voltage, as mentioned, is located on the body of the energy cell.

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 different types of sockets, but this does not provide 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;
a set of adapters for different types of laptops and mobile phones.

Let's start with the fact that there was no adapter for Asus eee 1025CE 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. The input is supplied with 15 V from the included charging power supply; the output round can 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 device output and the green indicator will light up. 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 via the main output and a mobile phone via USB, but the charging current via USB is negligible. 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.

Video: The simplest external battery for a laptop

Nowadays you won’t surprise anyone with a laptop. It has long become an integral part of modern man. Every day we can observe people sitting in a park or a cafe working behind it.

The difference between it and a computer is the ability to work without a constant connection to the power supply, but sooner or later, the battery charge will run out and you will need to replenish the energy supply. Many of us will close the laptop lid and move on calmly.

Now let's try to figure out how to charge a laptop without charging.

Charging methods

At this stage of its development, humanity has come up with several ways to charge a laptop without a charger:

Let's look at each method separately and analyze its positive and negative sides.

Solar panels to help

If you are a fan of spending weekends in nature, and not within four walls, and you simply cannot do without a laptop, then one of the solutions to the problem may be to purchase a solar battery.

This device allows the energy received from the sun's rays to be converted into electricity. The process of installing the equipment is very simple - to do this, you just need to connect it to the power socket.

There are two types of solar panels:

portable mini-battery - have small dimensions, but have a small amount of power reserve;
batteries capable of maintaining a large amount of equipment in working condition. A serious drawback and, perhaps, the most important one is its large dimensions and complexity in the installation process, which is not entirely suitable for picnics.

The advantages of this type of charging include the fact that with its help the operating time of our equipment can be extended by a couple of hours. Truly maximum operating efficiency can only be achieved in good and clear weather.

Among the disadvantages, it should be noted that it is impossible for us to work or have fun with a laptop while charging. This is explained by the fact that the voltage value is a changeable quantity. This type of charging can justify itself only in cases of prolonged exposure to sunlight.

External battery

An external battery is a portable device that, like solar panels, can increase the operating time of our laptop computer up to two hours. A standard lithium-ion laptop battery can hold a charge for 2-3 hours, but with an external battery the energy reserve is doubled.

Manufacturers give us a huge range of such batteries, which differ from each other both in size and energy reserve.
The undoubted advantages of this method include the fact that, regardless of the weather outside the window, you can always charge, unlike solar panels.

In most cases, all kinds of adapters are included, which will allow you to charge tablets, cameras and other equipment.

Charging in the car

This method is perfect for laptop owners who have a car. The only thing you will need besides the car is a portable inverter. Due to the fact that in the car, as a rule, there are no sockets, so you will not be able to do without this device.

The advantages of this method include the fact that you do not need to carry unnecessary equipment (solar batteries or external batteries).

Serious disadvantages include the fact that charging is only possible when the car is running. It turns out quite expensive.

The laptop charger is not charging, what should I do?

If our charger, for some reason, stops fulfilling its direct duties, do not rush to run to a computer service

Try to do the following:

Despite the fact that self-repair has its pros and cons, it should be resorted to primarily by those people who understand electronics and can personally find the cause of the charger malfunction. If you are not so strong in this matter, then it is better not to risk it and take your laptop computer to a service center. Otherwise, you risk making things even worse, resulting in additional repair costs.

These are the main ways that will help you charge your laptop without charger.

To summarize, we can draw the following conclusion: “It doesn’t matter for what purpose you use your “portable friend”, the main thing is that you can always restore its depleted supply of energy.” Which way to use chargers (solar batteries, external batteries, charging in a car) is up to you to decide.
