Problem
The power bank doesn't
charge itself properly.
Get a different working USB charging cable
and a 5V 2A wall charger.Try charging again.
I tried to charge the
power bank with solar for
3 hours, but the battery
level never changed.Be advised that it takes roughly35 hours
to geta full charge via the solar panel.
Charging speed depends on sunlight
intensity, solar panel size and the panel
conversion rate. Please try to charge it for a
few more days.
I've been trying to charge
my phone with the power
bank for 6 hours, but it
never reaches up to 33%.
2. Try to charge a different brand ofcell-
phone or other device.
1. Try using a different charging cable.
I charged the power bank
charged for a long time,
but the battery is not fully
charged.
1. If the charger you used is 5V 2A, it takes
about 6-7 hours to geta full charge.
2. If the charger you used is 5A 1A, it takes
about 11-12 hours to geta full charge.
The last indicator doesn't
illuminate after I've beencharging it for 10 hours.
1. If the last indicator doesn't illuminate
at all, please try a different USB cable
and wall charger (5V 2A).
2. If the last indicator flashes, the power
bank is almost fully charged, it may keep
flashing because of aresistance error
or arecognition issue inthe charger.
