Many, if not all battery packs do power off their outputs if the electric load on it is too light.
You could connect a resistor parallel to the 5 volt output to create a load, but that seems dodgy 🙂
Yes I saw that suggestion while searching online just now. Does seem a bit scary.
Another solution I think looks like is going to work is to connect an external USB hard drive to the other connection. I’ve had it connected for 20 minutes so far and all is still powered up. The power pack has been saying it has 90% charge since I switched on. Smoggie fan is happily purring away as well. Not a real solution though as I don’t want to leave my hard drive outside as I want to use it inside! Would have to buy another hard drive. This is getting expensive.
Thanks for the solution anyway
Mike
