★ Which one is faster between computer charging and adapter charging?

Connect the mobile phone and power bank through the USB data cable and press the switch button of the power bank to start charging the phone. At this time, the mobile power indicator lights up.
 
★ How long does it take to fully charge the power bank?
It is different according to the power bank battery capacity. it is recommended to use the output voltage of 5V-1A adapter for power bank charging, so that the charge per hour is about 1000mAh or so.
For example: Model: A100. Capacity: 10000mAh. Charging time is around 10-12 hours.

★ Can i bring the power bank with me on airplane?
According to the provisions of the Civil Aviation Authority of China, the limits are:
1, lithium metal battery lithium content of not more than 2g;
2, lithium-ion battery rated energy does not exceed 100wh;
3, more than 100wh but not more than 160wh, to be approved by the airline can be installed in the delivery of luggage or hand baggage equipment;
4, more than 160wh lithium battery is strictly prohibited to carry.
If you know the nominal capacity of the lithium battery (Ah) and the nominal voltage (V), then you can according to wh = v * Ah this formula to calculate the relevant value. Since the current mobile power capacity is in mAh (mAh), therefore, with Ah (ampere hours) multiplied by 1000 to get the corresponding mA (mAh) value. Since the voltage of the power bank is generally 3.7V, according to the above quantitative relationship, the nominal capacity of the mobile power source with rated energy of 100wh is about 27027 milliamperes, and the nominal capacity of the mobile power with rated energy of 160wh is about 43243mAh.
It is recommended that you contact with the airline before your travel.
