Can battery-powered Christmas lights be converted to work from a USB port? Yes, you can do it! That's what we'll see in this video, where I'll show you how to convert Christmas lights that run on 2 or 3 AA batteries to be powered by a cell phone USB charger or a rechargeable power bank. Since many of you have asked me, I also tried to do the opposite, which is converting lights with a mains voltage plug to work from a USB power bank, giving us the freedom to place them wherever we want without the need for cables and extension cords.
