This will attach the (very large) Anker 537 Power Bank to the back of a Steam Deck via DBrand's Killswitch case. Clips are added for the USB-C cable. The battery is held close to back of the Steam Deck to help with the balance, but this does add a lot of weight. This is great for long plane flights!
Requirements:
I added a few supports to the underside of some of the Killswitch adapter. The clips should be fine w/o them.
Thanks to x2brute on Tinkercad for the Killswitch adapters!
