How we examined
Determining whether or not an influence financial institution lives as much as an organization’s promise entails greater than merely connecting it to a telephone and charging. Testing battery packs is completed over weeks, not days, and requires additional tools so as to make sure the batteries work as anticipated.
- Upon receiving every battery pack, it was totally charged utilizing indicator lights as a method to trace cost stage.

There are some hiccups utilizing this technique, nonetheless. We had to make use of a GoPro digital camera to trace every battery by its cost cycle, because of the PortaPow monitor persevering with to gather information after the battery was totally charged (trickle charging is regular, and sadly interferes with our testing).

Power supply and cables
All of our exams have been performed utilizing the identical wall adapter and, when potential, USB-C or Micro-USB cable. This was accomplished to remove any discrepancies with wall adapters and cable throughput.
