Leading the charge to teach you choose the four points of on-board charger

Now in the market for most of the digital products charging line with standard USB plug, the principle of car charger is to convert voltage of 12 v car cigarette lighter socket to 5 v voltage and through the USB charging line recharge electronic products. So, we in the choose and buy car charger when how should choose?

1, please choose and buy regular trading. Please must buy normal manufacturer with after-sale protection products, don't buy and use 3 without the product, otherwise the quality problem of recourse, is too late to regret.

Again please understand when buying is Chinese printing packaging trading, because English packaging, mainly sold to foreign markets in domestic is out of the warranty.

2, understand the main parameters. In principle, as long as the charger at nominal voltage consistent with to charging device can charge, but the power of the charger is also a very important technical parameters, if use small power charger to power equipment can cause low power charger due to overheat and burn (such as the IPOD charger is absolutely can't give the), had better choose power for 1 a or 2 a charger.

3, choose to not choose. Although vehicle-mounted inverter can be 12 v power inverter into 220 v alternating current (ac), but the cost is high, and the use of high power devices can have influence on car, the car charger or converter is the 12 v dc conversion into 5 to 20 v direct current, low consumption, high safety coefficient, prices are much cheaper, so if use electrical appliances is not very special in the car with car charger or converter can meet the needs of most of the owners.

4, the safety is very important. Circuit design such as over-voltage, over-current, overheating and short circuit protection, more effectively protect your electronic equipment case also should adopt ABS flame retardant environmental protection material, already beautiful and safe.
