1. Contains 9 sets of power outage saving functions.2. Temporarily store current capacity and energy when power is off.3. Reopen the opportunity to accumulate the current capacity and energy used.4. Manual removal if no accumulation is required.5. Voltage current and capacity display on the same LCD screen, no need for cumbersome operations, only need to connect to the USB interface, you can monitor the phone’s charging status in real time.6. Intelligently memory charging capacity, can save the mAH input from 9 sets of charging devices after power off. Easy to view and check whether the charging device’s capacitance is true.7. U disk current detection, the working current of the u disk is between 50-100mA, when is exceeds 100mA, the u disk may be faulty.8. USB interface voltage detection, the external voltage of the USB interface on the computer is 5V+/-5%, the output current is relatively constant, generally 500mA, and the notebook computer only has 100mA.Specifications:1.
