Usb car charger for phone: description, reviews and pictures

Many motorists for the phone want to choose a quality USB charger. The models differ in nominal voltage, conductivity and ultimate resistance. The standard charger consists of an adapter, an expander and a trigger.

Cable for models is used with a USB connector. Some modifications are made with rectifiers. They also have a diode display system. The average model is about 300 rubles.

Homemade modification

Making a USB car charger with your hands is pretty simple. Trigger is more expedient to select a single-pole type. Parameter of the maximum voltage for it must be no more than 12 V. To connect the model to the plug is used yusb-port. A transistor is used as a binary type.

The nominal resistance in the circuit should not exceed 20 ohms. Before connecting the expander, a zener diode is installed. If we consider modifications to 2 A, then they have a tetrode. Most often this element is used with a beam type filter.

Choosing a good model

How to choose a car charger for your phone? First of all, the buyer must pay attention to the compatibility of the model. If we consider phones with 800 Ah batteries, then it is more appropriate to select models for 12 V. The expanders are used for both capacitive and operational types.
