If you owned a Steam Deck, the Deckmate should ring a bell. It’s a universal attachment system that goes on the back of your handheld device allowing you to mount pretty much anything from external batteries, SSD’s, and USBC hubs. It even includes a kickstand with unlimited angle adjustment to hold it in place. After months of teasing the ROG Ally now has the same attachment system titled the Allymate Grip.
You can buy the full attachment system with everything included for $49.00 here.
I received mine and decided to put it to use, showcasing the supplied kickstand and by attaching my INIU Power Bank.
