Articles and Lifehacks

To choose the right cable for home phones, you need to know in advance how the communication line will be used and what devices will be connected. For example, TRP wire is perfect for local and long-distance communications. If you plan to install a fax or modem, or use a telephone line to access the Internet, the best option would be “twisted pair”. And, of course, if you are going to use a (mobile) device, then you don’t need a cable at all.

Characteristics and features of using TRP cable

TRP is a single-pair telephone distribution wire. It consists of two copper wires with a diameter of 0.4 mm or 0.5 mm in polyethylene insulation, separated by a jumper. The wire is flat, most often colorless, and is used both indoors and outdoors (for example, on the external walls of houses). It will last more than 25 years indoors. Using small nails, it can be easily and conveniently mounted on the wall or in a special groove for hidden wiring. Sold most often in coils of 400 m or 500 m.

Using the TRP cable, you can run a telephone line, for example, from a distribution box located on the staircase to a telephone socket in the apartment. TRP is also used when installing intercoms.

Using twisted pair cable on telephone lines

A more modern cable for home telephones is twisted pair, or UTP. Its frequency characteristics are higher than those of TRP, and accordingly, the quality of communication will be better. There are many varieties of twisted pair cables that are designed to solve various problems. For telephone communication, a UTP 2x2 cable is used. It consists of 4 insulated copper wires, twisted in pairs, in a common polyvinyl chloride sheath. The twisted pair cable is attached to the wall using special brackets with nails. Sold in standard coils of 305 m. When laying a telephone line, you need to have a sufficient supply of cable, because It is undesirable to splice twisted pair cables - in this case, the quality of communication deteriorates significantly.

The use of twisted pair makes it possible to connect simultaneously to the telephone network and the Internet via one cable. And if you suddenly find yourself in a situation where you have to figure it out, then at least you will be provided with access to the Internet by a modem and a computer.

Extension cord for home phones

When a landline telephone needs to be moved to another location and the standard cord is not long enough, you can purchase an extension cord with a telephone connector on one end and a telephone jack plug on the other. The length of these cords can be different, you just have to choose the right one.

How is a USB cable different from other cables? The main parameters when choosing a USB cable are standards, markings and size.

Today, almost all multimedia devices are equipped with a USB connector. Sometimes the connection occurs through an extension cord, and not directly to the port.

You need to choose the USB cable correctly. Firstly, each cable has its own marking. For example, HIGH-SPEED 2.and 028AWG/2C+28AWG/2C.

So, if you need a cable that supports the USB 2.0 standard. or 3.0., then the inscription should read “USB High speed cable 2.0”. USB 2.0 standard. does not support cable marked 1.1.

A standard high-speed USB 2.0 cable consists of one 28 AWG twisted pair to carry data and a pair of conductors to carry power from 20 AWG to 28AWG. In addition, the USB cable must be shielded.

When transmitting a signal using USB, it is important that it does not fade. Therefore, when choosing a suitable USB cable, you need to determine the required size.

For example, the marking "28 AWG/1P.....", the first numbers mean the maximum length of the USB cable - 28 AWG = 81 centimeters. If 26 AWG, then the cable length is up to 1 meter 31 cm. With markings 24 AWG, 22 AWG, 20 AWG, the cable length can be up to 2.08 meters, 3.33 meters and 5.00 meters, respectively.

Therefore, if the length of a USB extension cable is 5 meters, but there are two pairs of 28 AWG wires inside it, then it does not comply with the standards. At this length it should be 20 AWG.

Another cable with a length of 1.8 and marked 24 AWG (which implies a maximum length of up to 2 meters) complies with the standard. That is, the actual length of the cord should not exceed the maximum permissible data indicated on the cable.

The marking also contains other data: a note that the cable is shielded - Shield; wires twisted into a pair - P (Pair); two conductors - 2C.

At the end of the USB cable there is a small thickening, a ferrite ring. It works as a filter against RF interference and is present in all high-quality USB cables. On some extension cords it is located at both ends.

If the USB cable is incorrectly selected, the speed of data transfer may be significantly reduced. Also, the system may not recognize a device connected via USB or simply stop seeing it at any time.

The longer the cable, starting from 3 meters, the more problems may arise. To ensure stable operation of a USB device, you need to choose a USB cable that is as short and thick as possible. Then, when transmitting data, there will be less resistance and less signal attenuation.

Combining all that has been written, we can conclude:

• to choose a high-quality USB cable, you need to check the maximum length and AWG value;
• the inscription on the cable should read HIGH-SPEED 2.0;
• at least one end of the extension cord must have a ferrite barrel;
• The cable length should be as short as possible.

Phones usually run out of charge at the most inopportune moment, when there is catastrophically little time to charge. We turn on the first charger we come across with a wire and wait... Sometimes the charge occurs quickly, and sometimes it takes a treacherously long time, and after a while we are again left without communication.

Let's look at the process of charging a phone and all its components. And we’ll try to give recommendations that will help you choose the right chargers and always stay connected.

Modern communication devices are charged from 5 Volts, this is the voltage that is present at the output of the USB connector of a computer, router, TV, and so on. Chargers that are plugged into a socket are usually equipped with this connector. But in addition to voltage, an important parameter is the current with which the charge occurs.

If we talk about a computer, then the standard maximum current value for USB 2.0 is 0.5 A (amps), which is not very much for modern devices. If the charging device requires a higher current (1-2 A), then charging will take a painfully long time and may never be completed.

Another USB 3.0 standard (the connector is indicated by blue plastic inside) provides a current of up to 1 A, which is much better, but such connectors are only available on modern computers (TVs, routers and other devices are usually equipped with a USB 2.0 standard connector or even a USB 1.1 standard). That is, if we need to charge the phone from a computer, we should, if possible, choose the blue USB 3.0 connector; the device will charge much faster.

It is no coincidence that universal chargers have different prices; in most cases they differ in the maximum possible charging current - the higher the price, the higher the current, as a rule, and, accordingly, the potentially shorter charging time of the device (in this case, we do not take into account the markup for the brand and design) .

Of course, it is important to know the capabilities of your device in order to choose a charger with the required parameters. As a rule, most manufacturers indicate a maximum current of 1 A. But not all actually provide it. To compare different chargers, we will use a tester that shows current and voltage, as well as simulating a consumer with different current consumption.

Ideally, the charger should output 5 Volts and the maximum current that the device being charged can consume. But in reality the picture is different. To eliminate the influence of the cable connecting the charger and the phone, we will connect the tester directly to the charger.

Test 1 (5 Volts and 1 A stated):

We see that the voltage is 120 mV lower than declared and the current is 70 mA less.

Test 2 (5 Volts and 1 A stated):

We see that the voltage is slightly higher than declared and the current differs from the declared one by only 40 mA.

Test 3 (5 Volts and 1 A stated):

We see that the voltage is slightly higher than declared and the current corresponds to the declared one.

Test 4 (stated 5 Volts and 0.7 A):

The voltage and current are significantly lower than the previous ones; you should not expect fast charging from this device.

Test 5 (stated 5 Volts and 1 A):

Voltage and current correspond to the declared ones.

Test 6 (parameters not indicated):

The voltage and current are lower than the previous ones, you should not expect fast charging from this device.

Test 6 (charger combined with a block of sockets, stated 5 Volts and 2.4 A):

Very decent parameters.

Test 7 (charger combined with a tee of sockets, stated 5 Volts and 1 A):

Very good results.

As you can see, not all manufacturers were able to provide the declared characteristics, and in those cases where the voltage is lower than required and the current is lower, we will naturally get a longer charging time for the phone or tablet.

The second important element in the charging process is the cable connecting the charger to the phone. There are many options for such cables, some even with backlight. However, their main parameters are the material of the current-carrying conductors (preferably copper) and the thickness of the conductor (the thicker, the less the cable will affect the charging process). Let's test several cables.

Test 0 (tester connected directly to charger):

Test 1 (cable included with Sony Xperia Z3):

A good cable for a current of 1 A, at 2 A there is an overload and loss of parameters.

Test 2 (cable purchased separately):

Good cable for 1 A, loss of parameters at 2 A.

Test 3 (cable purchased separately):

Bad cable, charging will be very slow.

Test 4 (cable purchased separately):

The leader in fast charging, according to phonearena.com, is the Samsung Galaxy S6 (1 hour 18 minutes with a battery capacity of 2,550 mAh). In second place is Oppo Find 7a (1 hour 22 minutes with a battery capacity of 2800 mAh), in third place is Samsung Galaxy Note 4 (1 hour 35 minutes with a battery capacity of 3220 mAh),

In fourth place is Google Nexus 6 (1 hour 38 minutes with a battery capacity of 3,220 mAh), in fifth place is HTC One M9 (1 hour 46 minutes with a battery capacity of 2,840 mAh). Fast charging technology is also supported by: LG G3, OnePlus One, Samsung Galaxy S5, LG G4, Samsung Galaxy Note 3, Apple iPhone 6, Motorola Moto G, Sony Xperia Z3 and a number of others.

So, if charging speed is important, you should choose phones that support QuickCharge technology.

Naturally, fast charging speeds are only possible when using high-quality chargers and cables that support the required currents and voltages. Of course, it is better to use the charger that comes with your phone. But if it is purchased separately, then when choosing, you should take into account the above described parameters.

So, you stopped at a kiosk or went into an electronics store to buy a charger cable. You need to choose a simple thing for daily use: a data cable or charger. How to do this so as not to give away your money for nothing and not get a harmful device instead of a useful one, which can ruin your smartphone.

Check the specifications

The first thing you need to pay attention to when buying a charger or a cable for it is whether they fit together. We are talking not only about the shape of the connector, but about the technical characteristics, the main of which for a smartphone charger is the output current (measured in amperes, A). For an average smartphone or tablet, this parameter ranges from 0.7A to 2.1A. Accordingly, the charger should indicate that it operates in this range.

What do we see on the back of any charger? In addition to the name of the brand and the country of manufacture, the voltage range of the electricity must be indicated here, that is, how much comes out of the outlet (usually 100-240 V/volt); frequency (usually 50-60 Hz) and Output - output, that is, the current strength with which the device is charged.

If you connect your tablet to a smartphone charger that outputs, for example, 1.0A, the device will charge slowly, but will eventually get the result. If a smartphone is connected to the powerful charging of the tablet, it will also not burn out, since all modern gadgets have built-in controllers that prevent them from drawing more current than necessary.

More current than necessary is the main problem with non-original chargers. Of course, as mentioned above, the controller will not allow the device to consume more current than it can “digest”, however, if the current indicated on the charger is more than 2 times higher than the specifications of the device, its battery may become very hot when charging, which may be harmful to it and in extreme cases even lead to fire.

Cable specifications are usually listed on the packaging, if present.

Advice. If your charger or its cable stop working, you should throw it away immediately. This is better than having to repair your smartphone later.

Choosing a lace

What should the charging cable be like? How to choose the best one - especially if you are choosing from a bunch of similar ones?

Insulation

Regardless of the connector, all cables today are braided differently. The cheapest are round wires with plastic insulation. They are a true consumable: they are inexpensive and don't last long.

A more expensive and at the same time long-lasting option is a flat cable. Despite the same polymer insulation as in the first case, its very shape is protection against creases and tangling.

Another convenient and fairly reliable option is a spring cable, like an old telephone or car cable. There is no need to fold or twist it at all, but if it does get tangled or twisted, there will be little joy. Such cables, like the previous two, are inexpensive due to the polymer braid.

The most reliable option is a fabric-braided cord. Although it is not so compact, it is unlikely that it will be possible to twist it tightly, but it can work for years.

Plug material

When choosing a cable on the market, you can hardly find out what its connector is made of, but if you purchase a cord in a store, you can look at this information on the packaging. The cheapest cables are traditionally equipped with a plastic plug, but more expensive options can be either hybrid or completely aluminum. This is probably the most reliable, albeit expensive option: they do not become loose or wear out.

Of course, the saddest thing is that with all the abundance of cheap charging cables and devices, no one can guarantee that everything will be fine and nothing will happen to your device. The fact is that the companies producing this consumable do not need to certify it, and there are not even any special recommendations.

The only exception is the “Made for iPhone” program, but that’s why it’s Apple.

Perhaps the only person in the world concerned about the problem of poor quality USB-C chargers is Google engineer Benson Leng, who is collecting information to compile a database of such gadgets. He himself recommends that when buying a non-original and inexpensive charger, rely on God’s help - or buy devices that he has tested with his own hands.
