What is car charger?
Car chargers are regular car chargers powered by car batteries (12V for cars and 24V for trucks), which are widely used in the field of Lithium battery charging for all kinds of portable devices.
Car charger is an extra charging device for car anytime and anywhere. Most high-end car chargers contain two USB ports, which can charge two digital devices at the same time.
A qualified car charger has many requirements, the most important of which is to have circuit overload protection because it can immediately cut off the power in case of a short circuit to avoid damage to the charging device and power supply. An unqualified car chargers cannot stabilize the voltage and current, which can affect fluctuations and cause serious over-heating of the charging device and charger, which is related to cell phones and safety.
Why you need a extra car charger?
As many families now have various device such as laptops, ipads and car refrigerators in addition to cell phones.A built-in dual port car charger is not enough for our daily charging requirement. If there is a traffic jam or important work needs to be dealt with, but the laptop run out of power, which greatly affects our work efficiency.
And for many Android phones now have fast charging function, if our car charger adding fast charging function,it can quickly charge our cell phone anytime.
For this reason, adding a charger to our car can greatly improve our efficiency and happiness, but how do we choose a best car charger?
What is a best car charger?
In choosing a best car charger, we have some ideas as below:
1)Battery voltage for car
In general, the car battery output voltage of 12V, 24 V for trucks.Nowday,most of the car chargers support 12V-24V voltage input, but we should check carefully the voltage to avoid damage to the battery.
2)Standard car charger or fast charger
Standard fast charging: support 2.1A, 2.4A, more suitable for iphone and part of the phone does not support fast charging
Fast charging: fast charging is generally support fast charging protocol, there will be differences between different phones.Before buying a car charger, to determine which fast charging protocol your phones support.
3) Safty and protection
We should choose a car charger with overvoltage, overcurrent, overheating, and short-circuit protection. And the car charger case must be made of flame-retardant material to prevent spontaneous combustion under high temperature.
4) Phone protocol for the car charger
Fast charging protocols currently are mainly as following.
QC protocol (Qualcomm system models), PD protocol (iPhone), which is more widely compatible Samsung’s AFC protocol, Huawei’s FCP and SCP, OPPO’s VOOC protocol, a plus WARP protocol.
You should choose the car charger support QC and PD protocols to achieve fast charging of 18W and above.
If you need to power your laptop, you need to support 65W and higher output with the USB-C interface (PD protocol).
For this reason, choosing a good car charger requires many aspects combined with your different requirements. Being a professional car charger manufacturer, we have more than 10 years of car charger production expreirence, with the ability to independently develop products, we can provide our customers with professional customized solutions, and also accept OEM and ODM orders.
