BG111516572 Yes, there is no MPPT, so the best approach is to charge a powerbank with the panel instead of phones and other devices.

therealprof well, that’s exactly what I’m doing, however a powerbank is similar finicky to a smartphone since they use the same charge controllers. It’ll certainly address the problem of charge interruptions but it doesn’t address the issue that you can’t get the maximum power out of the panel.
