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
Reserved and shared. Your design is crazy good, Apple could sell it in their stores
How do you do QI charging through the magnetic plate?
Maker
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.
Maker
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!
For someone who just bought a 10'000 mAh wireless charging powerbank with USB A and C ports in similar size for less money, they do look kind of pricey to me.
"The world’s first wireless battery pack" seems like a cool product and it looks a nice color etc. but this statement is very disingenuous and unnecessary. I've had a wireless battery pack for over a year from other manufacturers.
which one? I somehow wasn't aware they exist, would like to look into it
Definitely not the first wireless battery pack but its unique and different than anything else.
thanks, I guess I somehow missed the whole wireless revolution 😆 I do agree though that Bunk here looks pretty unique but part of the appeal probably comes from the nice marketing.
Looks really cool! As a traveler and digital nomad, I’m using my phone quite a lot throughout the day and out off battery pretty quickly. This could really help me!
A hardware product! And what a clever and beautiful one! We need more of them here! 😄
Great job on the product's design, looks super chic. Picked one up for myself! Curious to see how the N52s do their job. Quick feedback on the website: Picking a color while checking out could be more visual. Had to scroll through the landing page a few times to figure how each color(+pattern) would look.
wish i had it right now
Nice! Looks like a big improvement to my battery pack
At 50% off it is a great price but I think it might be a bit too thick for me... and my phone doesn't support wireless charging. Maybe a good idea to create a case to add wireless charging to a phone?
Oh yeah you are right my bad. I missed it the first time I read it.
