Portable Power Bank 5v – On/Off Switch and does not shut off automatically

Great item for costumes with electronics, lights, sound or fans.

Unlike a lot of other power banks, this one has two great features if you have electronics in your costume:

1. Has an on-off switch. You don’t need to unplug the cable to turn it on and almost 100% of the time forget to remove it, resulting in a dead helmet fan or sounds.
2. Runs low power electronics, like our 4-button or 8-button sound player. Most sound banks turn off after a few seconds if they run small electronics that consume very little power.
