1.Power bank unable to charge my tablet?
a) Power bank with 2A output to charge tablets. While some tablets can accept lower input (1A or 1.5A), the charging is slower and sometimes can only be charged when the tablet is in sleep mode.
b) Some tablet is cables might not be compatible with power bank due to different cable chipset design. For Samsung Galaxy Tab in particular, we recommend using the cable and connector meant for power bank (comes with some power banks.

2.Power bank battery drained off very fast?
a) Generally, a well maintained power bank can retain up to 80-90% of its original capacity. Please check your device (phone/ tablet) original battery capacity and the power bank capacity. Please also see answer 1.a. above.
b) The number of times a power bank can charge your device very much depends on the capacity of both the power bank and the device. Examples of calculation shown in answer 2 above.
c) Please do not attach cables to the power bank when not in use.

3.Unable to turn on my power bank?
a) It is possible that your power bank is fully drained. Please charge your power bank. The indicator will start blinking when the power bank receives sufficient power.
b) It is possible that your power bank went into sleep mode. The power bank will automatically cut-off the power and go into sleep mode when it detects possibility of over-charge/ over-discharge/ short-circuit. This is sometimes due to faulty cable issue. Please activate the ìsleepingî power bank by charging it with its wall plug (3-pin plug) and use a good condition cable.

4.What is the lifespan of the power bank?
Generally, a properly maintained power bank can retain up to 80-90% of its original capacity at 400-500 charge and discharge cycle (charge then discharge = 1 cycle, regardless of whether you charge/ discharge it partially or fully). Until your power bank no longer holds sufficient charge to meet your needs, you may choose to purchase a new one.
