Hey Product Hunters, Don’t you hate it when your battery runs out at the most important times? But don’t want to resort to ugly, heavy power bricks and cases? We designed Bunk from the ground up to be the most convenient, easy to use portable smartphone battery ever. It just snaps to your phone magnetically and start charging! 80% of smartphone owners suffer from “range anxiety” but we all know how inconvenient (and ugly) existing battery cases and power bricks are. So we built Bunk to solve that. Packed with a 1800mAh battery, 3-coil magnetic transmitter, and magnets with 80N of force, Bunk snaps perfectly onto your phone every time and provides charge. Other features include: •Auto on/off — shuts off when detached •Pass-through charging •Support for devices without wireless charging (via our super-thin receiver) We’re so happy to share our invention with you and we’d love to hear any kind of feedback! Thanks! Daniel and Will

@15greenberg Reserved and shared. Your design is crazy good, Apple could sell it in their stores

@15greenberg How do you do QI charging through the magnetic plate?

@guillaumecabane Hi Guillaume! The magnetic layer has been carefully designed. We've placed the magnets on the far edges of the part to avoid it interfering with QI charging.

This is magical. Can you maybe give a brief explanation of how this technology works because I wasn't even aware this was possible.

@dkb868 We're using QI Wireless Charging to supply the charge - it's a standard that has been adopted by Apple, Samsung, Google (and essentially every other smartphone manufacturer) which makes Bunk near universal. No more searching for USB-C or Lightning cables! We're really excited to get this into people's hands!

My iPhone always runs out of battery but I refuse to buy any of those battery cases out there since they're so bulky and ugly. This looks to solve that, and the magnetic snapping feature looks super cool.

Pros:

Beautiful product design, solves a big problem

Cons:

None
