I have a Tent with built in LED lighting and the switch is illuminated, so you can find it at 3:00AM when you go for a wee. It uses 5V over a USB-A plug. Quite nifty!
The problem is that it does not adhere to the USB spec so after a minute, the power bank decides that nothing is connected and stops supplying power (as a safety feature). You then have to wake up the power bank back up to can find the light switch, which you can’t do without lights on.
