Does the power button turn it on and off or simply light up the status? I'm looking to physically turn it on and off regardless of if it's plugged in.

It’s a power bank. You only plug it in to charge up the battery for use. Then you unplug it. The button does show the battery status. When you unplug what you are charging with the power bank, it shuts off after a few minutes. It automatically turns on when you plug a device in to charge. There is nothing to turn on or off.

How long can it store a full charge when unused?

Uncertain, but several days. Will completely charge my Android at least 3 times between charging it up again.

Could a 5V/1A micro usb solar panel recharge this battery bank? Any idea what the minimum charging current is?

That's a good question. Given the device can use a standard USB Micro port for charging via wall adapter, it should also be able to be charged using a solar panel. Might take longer though given the less amperage the solar panel uses than a standard wall power adapter. I personally use a USB Type C cable to charge the unit, since it does have both options for charging.
