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
