Have you ever bought power banks in the past and realized they don’t hold charge after a couple of years? A lot of older power banks had non-removable batteries. The ZERO Power Bank takes a different approach. It is a portable power bank with a modular design and swappable cells, so you can always repair it. It has 21,000mAh capacity and a 100W USB-C output, so it can charge your laptop. It can also charge a device wirelessly at 15W and another device at 18W.
You can link up to 5 of these in parallel to increase capacity. This power bank has enough capacity to charge your smartphone up to 4 times and action cam up to 9 times. It uses a full BMS with cell balancing for safe operation. You can buy light and various other add-ons to do more with this power bank. This project is currently on Kickstarter.
