Guide To Buying A Power Bank - Things To Consider When
Buying A Power Bank
1. ----» What is power bank?
A power bank stores electric charge serving as a
reserve for charging for phone and laptop
batteries.
2. ----» Where is a power bank made from?
Most brands of power banks are manufactured in
China.
3. ----» How do I charge the power bank?
To charge your power bank, connect the device
charger to a wall outlet, computer USB port or
another power bank.
4. ----» How long do I need to charge the power bank?
Charging duration depends on the true capacity
of the power bank. Also an original charger
would charge faster while charging via a
computer usb would be slower.
5. ----» Why does it take longer time to charge the
same power bank sometimes? Charging time may
fluctuate due to temperature, power flow and
environment even while using the same charger.
6. ----» What is mAh?
The standard unit of measuring the capacity of a
pwer bank is mAh ( which means milli Ampere
Hour)
7. ----» How do I calculate how many times my power
bank would charge my battery to full capacity?
A common error many people make is to assume
a 12000mAh capacity power bank would charge a
1500mAh capacity phone battery full for 8 times.
This is the formula to calculate total charge time.
Power bank capacity x conversion rate x phone
battery health / phone capacity = total charge
time (cycle)
From the example above:
12000 x 0.8 x 0.8 / 1500 = 5.12 charge times (+/- 0.5-1.0)
conversation rate - percentage of charge left in the
battery after loss through heat and PCB
operation.
phone battery health - the efficiency of the phone
battery to hold charge. This efficiency diminishes
with battery use (repeated cycles of charging and
discharging).
9. ----» What is the difference between a 18650 and Li-
Polymer power bank?
18650 power banks are cheaper, commoner,
produces more heat, has fixed dimensions and
higher self discharge rates while Li-Polymer
batteries are better, safer, more expensive but
more durable, with flexible dimensions and
produces less heat
10. ----» Can a power bank explode during
overcharging or overheating?
Whether you use a branded or generic power
bank, batteries have the tendency to explode.
However, this should not scare you because the
chance of power banks exploding is nearly zero.
Look at it this way, if power banks explode easily
people would have preferred them in wars
instead of bombs.
