Pls read me before you make order：

Every order is hard-won for us, we will take every customer seriously; sincerity is our principle.

Common product questions:
(1) Does the mobile power supply have low voltage protection function?
All startup power supplies in our store have 12V overvoltage protection, so don't worry about damage.
(2) Under what circumstances does the startup power supply fail to work?
If the instantaneous current of the DC port is greater than 10A, the protection will be triggered (the start-up and peak current of the EC5 port will be greater than 10A).
When the battery voltage is low; the starting power caused by the engine cannot start the car;
When the smart clip is not connected normally; when the machine is triggered by short circuit protection.
(3) The flashlight cannot be used, what is the reason for the failure of starting power charging?
If the flashlight cannot be turned on during charging, you need to unplug it. If the battery cannot be charged, it may be caused by the large internal pressure difference of the battery. You can try to discharge the battery and then charge it.
