Some high-end car charger typically includes two USB ports, which can simultaneously charge two digital products. These products generally feature overload protection, short circuit protection, high voltage input protection, high temperature protection to ensure safe use to realize car charger direct charging, USB charging and triple multi-use while being charged in the car.


The voltage outputted by car charger is typically 5V transferred from 12v-24v and limiting current is 500mAh, for those knock offs without protection function, the circuit has many flaws, if the buck and current limiting circuit fails, it will lead to 12-volt direct accessing to the phone, resulting the phone  burned. It is recommended to use the the original charger after car inverter volt rising to 220.
Conventional car charger powered by car battery (car 12V, trucks 24V) is widely used by a variety of portable, rechargeable handheld devices equipped with lithium battery, such as: mobile phone, PDA, GPS, etc; car charger do not only consider the actual demand (constant voltage CV, constant current CC, OVP OVP) on lithium batteries, but take into account the harsh environment of automotive batteries (transient voltage spikes, the system switching noise interference, EMI, etc.); therefore Power Management IC of car charger program must be switching power supply chip featuring with high pressure, high efficiency, high reliability, low frequency (in favor of EMI design).
