  • i am looking to do similar to gumbergules to combine 2 boards in series to get 10v output. Is it possible to arrange the chargers in series with a single 10v power supply? also if i have 2000mAh bateries is there a setting to get 2000mAh or a similar product that will do it.

  • Is there a way to charge the series multiple charger/booster configuration without disconnecting them? I assume the grounds aren’t isolated on the board so you’d have to either provide 10V split between the two USB ports or charge from two isolated 5V outputs, right?

    • Two isolated 5V USB chargers is the way to go. Ours are all isolated, and I haven’t come across one yet that isn’t. At least here in the US. Note, USB chargers with two USB ports are probably not individually isolated so use two separate supplies.
