The tablet is a very useful thing and one of the most useful inventions of the 21st century. After all, such a small computer can serve as a navigator, an audio-video player, a camera, a video camera, and even a mobile phone. In addition, it has Internet access and the ability to download a host of other applications. In general, for a modern person this is an irreplaceable thing. As for the memory, this element is always included in the package.
However, sometimes it becomes necessary to purchase car devices with a cigarette lighter socket. But be that as it may, it is a stationary charger for a tablet or a car charger, its principle of operation and purpose remains the same - charging a lithium battery of a tablet computer.
Varieties
At the moment, there are several types of memory for such gadgets:
- Universal.
- Specialized.
- Automotive.
- Alternative (powered by solar energy).
- Portable.
And now, in more detail about how each of these types of devices works.
Universal Memory
Such a charger (for an Asus tablet as well) is a device that converts the input current of 220-240 Volts to a voltage of 15-20 Volts, sufficient to efficiently charge the battery gadget. They are unique in that they can be applied not only to tablet computers, but also to some laptop models. The emitted current of universal chargers is about 3.42 A, while the power is not more than 65 W.
Specialized
This tablet charger is used to a lesser extent, since it is intended only for a specific model and type of battery. At the same time, such a charger (including for the Samsung tablet) costs an order of magnitude higher than the same universal ones.
Automotive
Such memory devices have their own special cylindrical connector and are included in the car interior in the cigarette lighter. There, the car battery supplies the rated current to charge the device. The voltage of the converted current is 15 volts, which is not much different from stationary home counterparts. But the current strength is not enough - only 1.2 Amperes, so you need to charge such a device 2-3 times longer.
Alternatives
The most interesting option is the chargersolar powered tablet device. Such a device is especially popular in some European countries, such as Germany, England and France. They are arranged in such a way that for charging you do not need to look for a source of direct or alternating current. All you need to do is hold the charger up to the nearest beam of sunlight and wait for the tablet to charge.
Portable
This is a special lithium-ion battery that comes with a USB charging cable. It also includes various adapters, which allows it to be used on many models of tablet computers. The capacity of these lithium-ion energy carriers can be several thousand microamperes.
