Looks and works great. However I've no idea how to get 40W out of this thing, in bright sunlight I can't get more than 20W combined. Also devices are ramping up their much power up to the possible max which under non-ideal conditions means the voltage breaks down before even 5V/2.4A are reached causing the device to reset and start over; I haven't found a single device that would even attempt to negotiate a higher voltage PD under those weird conditions, not even sure how that would even work given that the voltage already cuts under the minimum 5V frequently. It seems this really does not have any MPPT or at least a usable current limiting and buffering to provide a stable voltage.

  • 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.
