A 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, and an audio-video player, camera, video camera and even a mobile phone. In addition, it has Internet access and the ability to download tons of other applications. In general, for a modern person this is an irreplaceable thing. As for the memory, this element is always included.
However, sometimes it becomes necessary to purchase automobile devices with a cigarette lighter socket. But be that as it may, a stationary
charger for a tablet or a car, 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 sunlight).
- Portable.
And now in more detail about how each of these types of devices is arranged.
Universal memory
Such a charger (including for an Asus tablet) is a device that converts an input current of 220-240 volts to a voltage of 15-20 volts, sufficient for efficient charging of a battery gadget. They are unique in that they can be used not only on tablet computers, but also on some laptop models. The published amperage of universal chargers is of the order of 3.42 A, while the power is not more than 65 W.
Specialized
Such a charger for the tablet is used to a lesser extent, since it is intended only for a specific model and type of battery. At the same time, there is such a charger (for the Samsung tablet as well) an order of magnitude higher than the same universal ones.
Automotive
Such memory devices have their own special cylindrical connector and are plugged into the cigarette lighter in the passenger compartment. There is a car battery and supplies the rated current for charging the device. The voltage of the converted current is 15 volts, which is not much different from stationary home analogs. But the current strength is small - only 1.2 Amperes, so you need to charge such a device 2-3 times longer.
Alternative
The most interesting option is a tablet charger powered by solar energy. Such a device is especially popular in some European countries, such as Germany, England and France. They are arranged in such a way that you do not need to look for a source of direct or alternating current for charging. All you have to do is bring the charger to the nearest sunbeam and wait for the tablet to charge.
Portable
This is a special lithium-ion battery, which is additionally equipped with a USB cable for recharging. 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 microamps.
