Instructions of Car Charger

Generally, the car charger of GPS, mobile phone is used with built-in voltage converter circuit which can convert it into voltage 5V to compatible with the USB interface, so that when the use of USB charging cable can be plugged into a computer USB port, and charged into the car. As for the nominal charge current of 1.5A, it means that it is capable of providing the maximum output current, but not once connected to GPS, mobile phones, it can have such a big circuit, which is easy to understand for people who have studied Ohm's law.

Reasons for a car charger to cause failure are the careless design of vehicles and the shoddy production quality, while the common reason is blown cigarette lighter car insurance, so it is important to choose a high quality car charger.

Warning:
1. Do not insert a car charger used  DC power supply in converter.
2. Do not put converter under the place where the temperature higher than 50C.
