"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.
@anna_0x there are loads on Amazon. Just search for wireless battery or "qi battery wireless"
e.g.

@anna_0x @_jacksmith Definitely not the first wireless battery pack but its unique and different than anything else.
@_jacksmith @imafricanjesus 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.
@15greenberg This looks similar to Brickspower (http://www.brickspower.com). How is Bunk different?
@scottwwilliams both products claim to be the "first wireless charger" when others are already available on Amazon.
@scottwwilliams Hi Scott, great question! We've been developing this with an incredibly talented design team for over a year and we've managed to identity and overcome some serious design issues with Bunk in that time. Brickspower definitely hasn't received the same level of love, and fails in a couple of areas.
The main one is its attachment method - Bunk is magnetic so snaps onto any surface (including the 79% of users that use a case!) and it auto-aligns with the phone's wireless receiver coil perfectly each time. Brickspower requires a gloss surface to stick to the device, and for the user to carefully align it by eye each time they need to charge. Without perfect alignment, wireless charging becomes really inefficient.
We made sure that Bunk is as simple and hassle-free as possible so that it truly works for users as a solution to on-the-go charging, it's really something special!.
@15greenberg, @willkail Can I use other wireless charging pads if I have the magnet piece on the back of my phone?
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.
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.
I just did a review on YouTube of two popular Qi power banks. So this would be a great follow up to that!
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
@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.
Why this requires a specific iphone case is beyond me. Their same tech could be made universal by just pulling the mag tech out of the case and making it an adhesive to back of phone/current case.
Pros:Extra Battery Life, Hot-swappable
Cons:Requires a separate case, Lacks universal support for Android and Iphone
@james_alexander1 I think you're confused! Bunk is universal and works cross-platform/with any case! It does use an adhesive magnetic layer that sticks to the inside of your existing case.
Check out our site to inform yourself a bit more about Bunk! ⚡
@james_alexander1 @willkail question: even if the phone supports wireless charging out of the box (I have the Note 9), Hunk still requires a sticker/case? Can the sticker be used without a case?
@anna_0x Hi Anna! You can use Bunk without a case - you'll just need to attach our magnetic layer straight onto the back of your phone rather than on the inside of the case. We found that most people used cases but we also really wanted Bunk to work with those who choose not to use one!
