First: The mobile power cannot be turned on Check if the battery is low. The newly purchased mobile power supply may not be charged at the factory and its power is zero, which causes the mobile power supply to fail to boot. The solution to this situation is very simple, first charge the mobile power for 3-5 minutes to boot.
Second: The mobile power cannot be turned on. Check if the current is too large due to the automatic protection of the mobile power. In the event of a short circuit, the protection board automatically activates the protection function to shut down the mobile power. At this time, the mobile power source can be charged and the mobile power can be reactivated.
Third: The mobile power cannot be turned on to check if it is due to an operation error. Like the mobile power supply of the Protoss factory, the power on is required to press and hold the power button for 3-5 seconds. Many first-time users do not know that the switch is turned on because of a single press. Because each company's operation is not the same, if it is a mistake, it is recommended to look at the instructions, the general problems can be solved.
Fourth: The mobile power cannot be turned on Check if the product is damaged. If the above situations have tried mobile power or can not boot, it may be that the mobile power has been damaged. If it is within the warranty period, it can be repaired directly.
Last but not least, when people buy mobile power, they should pay attention to the authenticity of the purchase. Do not buy counterfeit goods or counterfeit products. If so, don't expect too much after sales.
