Portable Power Supply

A: A portable power supply is a portable energy storage device with a built-in lithium battery. It can power or charge digital devices such as mobile phones, tablets, and cameras through USB, DC and other interfaces. It is suitable for outdoor and emergency scenarios.

A: Choose according to needs. 2000-10000mAh is suitable for charging mobile phones, and 10000-20000mAh can power tablets and notebooks.

A: It is necessary to comply with airline regulations. Usually, a rated energy of ≤100Wh (about 27000mAh) can be carried with you, and more than that needs to be checked in.

A: Use the original or compatible charger to avoid overcharging; When charging, the indicator light turns blue/green and is always on, which means it is fully charged.

A: Yes. When the total output power does not exceed the rated power of the power bank, it can be charged at the same time, but the speed of a single device may decrease.

A: Yes, but using it while charging may cause the phone to heat up or charge more slowly.

A: Press and hold the power button for 2-3 seconds; If it does not work, it may be insufficient power or hardware failure. Try again after charging or contact after-sales.

A: Check whether the charging cable is matched, whether the interface is loose, or try to replace the cable/device.

A: The power is exhausted, the load power is too large, or the temperature is too high to trigger the protection mechanism, and it needs to be restarted after cooling down.

A: Avoid overcharging and over-discharging, and use it regularly (charge to 50%-80% every 3-6 months for long-term storage).

A: Dry and cool place, temperature 15-35℃, humidity 35%-65%, away from heat sources and flammable materials.

A: Wipe with a soft cloth to prevent liquid from entering the interior.

A: Avoid falling, high temperature, and humidity; Do not use damaged wires; Do not use overload.

A: Look for 3C certification, choose well-known brands, and check whether the shell is flame retardant and the battery protection circuit is complete.

A: Fully charge in advance, turn off unused device functions, and give priority to powering key devices.

A: Turn off non-essential background programs, use low-power mode, and avoid frequent switching on and off.

A: Unfold the solar panel when the sun is sufficient, adjust the angle to the sun, and the charging efficiency is affected by the light intensity.

A: Some power supplies with emergency start function can be temporarily charged. Please follow the instructions to avoid connecting the wrong polarity.

A: Lithium batteries have self-discharge characteristics. If the abnormality is serious, it may be that the battery is aging and needs to be replaced.

A: Some power supplies can be calibrated through the official APP, or fully charged and discharged once and observed.
