cable chipset design. For Samsung Galaxy Tab in particular, we recommend using

Unable to turn on my powerbank?
a)
It is possible that your powerbank is fully drained. Please charge your
powerbank. The indicator will start blinking when the powerbank receives
sufficient power.
b)
It is possible that your powerbank went into sleep mode. The powerbank 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 sleeping powerbank by charging
it with its wall plug (3-pin plug) and use a good condition cable.

What is the lifespan of the powerbank?
Generally,
a properly maintained powerbank 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.

particularly when you are on outdoor or during calamities when powergrid are
