Designed to clip directly to your Steam Deck, the Battery Backpack allows you to attach a battery bank to extend the battery life of your Deck.
We designed the backpack to clip on easily but also not block any integral ventilation components of your Steam Deck.
Made with multiple attachment point the Battery Backpack can accommodate multiple battery sizes and variations
Nylon Velcro Strap: Attach any style of battery bank from large to small in both vertical and horizontal orientations.
Clip-On Mount: The Battery Backpack is perfectly fitted to the Steam Deck and snaps on and off with ease.
Rubber Grips: Made with 3M rubber grips to keep your battery bank firmly in place while using your Steam Deck.
Loved the old design, but it was a bit to weak and broke right away. Now having this new design which is much stronger helps out a ton. Tested it and it does not break like the old one. I like this battery holder more than other battery holders I have tried for the steam deck so far.
It breaks easy when packed into a backpack :|
This thing is everything I could want in a mount. It straps both ways, it keeps batteries locked in tight, it secures to the steamdeck nice and crisp, its lightweight and universally accommodating for even the beefiest cells (within obvious reason of course). I'm beyond impressed.
