      When get USB-C power from my desktop or laptop computer, my LILYGO LoRa T3-S3 works great. The blue LED comes on, it boots, and it operates, flashing the green LED.

      However if I try to plug it into any of my powerbanks, the blue LED comes on, but it refuses to boot. This is on three different powerbanks with USB-C supplies, from different manufacturers including Anker, as well as two very large batteries (Jackery and Bluetti), also with USB-C supplies.

      I have a USB-C power monitor, and shows 5+ V being supplied in all cases, powerbank or computer, with a few ten's of mA draw.

      Why is this radio refusing to work with powerbanks?

        @madler Are you bringing the PowerBank power into the USB-C connector on the board? Then maybe the power bank cannot detect the LilyGO board, due
        to small current consumed. This is a common problem with power banks!

        Or the 2 pin battery connector? Possibly GPIO 35 must be enabled for battery.

        You could raise an Issue here:
