车载充电器产品遍布市场和网络. 不管车友是在店里买还是在网上买, 类型不均匀. 我们知道车载充电器的价格并不是很贵, 但是如果车载充电器是针对假冒产品购买的, 可烧汽车保险丝及数码产品. 甚至可能危及人身安全. 那么如何提高选择优质车载充电器的技巧呢？?
1. 首先, know the output voltage of your car’s cigarette lighter
The car output voltage is 12V, the truck is 24V, the general-purpose car charger (12V) is mostly suitable for cars, if it is other models, it needs to choose the corresponding voltage standard. There are many car chargers that can meet the 12v-24v standard, 那是, all models are applicable.
2. To understand the auto protection function of car charger
Whether the on-board charger has over-voltage, over-current, overheating, short circuit protection and other functions, and the shell is preferably made of ABS flame-retardant and environmental protection materials, which can prevent external combustion as well as make it beautiful, with no hand print left when touching.
3. Pay attention to the voltage and current
When purchasing car charger, pay attention to the voltage and current of supporting equipment, 例如, iPhone is 5V / 1一个, tablet and mobile power supply are mostly 5V / 2没有一定的标准，一般按其分类. If the dual USB interface car charger charges the mobile phone and tablet computer at the same time, the total current of the car charger should be at least 3A or above, otherwise the charging speed will not only drop significantly, but also overheat or even charge the device.
4. Understand the total current of the charger purchased
一般来说, regular products will indicate on the charger how much a the output current is. If the purchased charger charges the mobile phone + tablet computer slowly and generates a lot of heat, it means that the current is not up to standard.
