QC3 isn't needed to charge the battery. A regular 5V, 2.4A power bank would charge the Spark battery. It just becomes a question of how long it takes - 1h, 2h, 4h per battery?
The standard Spark charger is 12V 1.5A / 9V 2A, which means it outputs 18W. If a powerbank can output that much power, then why not?
According to http://www.androidauthority.com/ ... 0-explained-643053/, "Version 2.0 supported four modes at varying power levels, 5 volts/2amps, 9V/2A, 12V/1.67A, and a 20 volt option.", so in theory, a powerbank that supports QC2.0 with documented manufacturer specifications that it is capable of outputting 9V 2A should do the trick. This power bank would need to be verified using an appropriate gauge of some sort in between the power bank and battery to confirm that the power bank is pushing that wattage when connected to the battery.
Does this make sense? |
