I bought a portable 30W solar panel to get ready for the apocalypse (feddit.uk)

I'm only half kidding. I'm a bit of a prepper and I have lots of powerbanks and devices that charge from USB but besides idling my truck I really had no other way to charge any of them in case of a long-term power outage which seemed a bit of an oversight on my part.

Not like this solves the issue. 30 watts (under ideal conditions) isn't much but it's a start.

The battery can discharge itself through connected solar panels. It's a known issue

Oh, I hadn't heard about it anywhere else. Do you remember where you heard this?

    I spoke with Jackery's customer service and tech support several times. I was depleting charge while leaving panels plugged in in full sunlight. They'd informed that the power feed can back flow to the panel, and that it is a known issue.
