Smartphone battery life sucks and carrying power banks around with you is one way to keep your handset juiced up. But it’s easy to forget to bring a power bank or to charge them up to take with you in the first place. This contraption that you can build yourself could be a good alternative to keep your phone charged up, albeit at the expense of your friends’ handsets’ battery life.
Hardware hacker Rulof Maker, has made a small portable device can suck the battery from one phone to another. This was done through modifying a few electronic bits and combining them into a gadget that he can carry around on a keyring so he’ll never forget to bring it.
What you’ll need for this project is a motor from an iPhone fan, a circuit board from an inexpensive USB power bank, a Lightning-to-USB cable, a small wood block and some soldering skills.
Maker’s gadget is made to steal battery from iPhones but there’s no reason you can’t use a micro-USB or USB Type-C cable for this project.
You can watch the video above for detailed instructions.
