As you’d expect, I’ve been browsing 4th of July handheld deals and found a pretty nifty Jsuax ModCase offer. The discount takes the form of a power bank bundle that just so happens to include theAsusROG Ally version, but you’re getting the whole lot for $5 less than buying the 20,000mAh bank on its own. Simply put, you’ll be able to spend less on a modular case that can wear an external battery like a jetpack, which in turn will help protect your pricey handheld and increase your playtime tenfold.
Over at Amazon, the Jsaux ModCase for ROG Ally with 20000mAh Power Bank bundle is downto $54.99 (was $79.99). The modular shell costs $29.99 at full price while the battery pack will set you back $59.99, so I don’t think it’s unreasonable to say you’re practically getting the case for free. Looking back at price history, it looks like this is the first time the bundle has received a discount, with offers normally applying to individual items.
If there’s one thing I love more than picking up thebest Steam Deck accessories, it’s saving money on them. Therefore, I immediately started checking individual deals upon spotting this ModCase offer. At the moment, you can pick up the shell separatelyfor $19.99and use a $5 off coupon to bring the Jsaux Power Bank downto $54.99 at Amazon. Add those two together using an abacus and you’ll get $74.98, meaning you’re saving $19.99 in real terms.

Should you buy the Jsaux ModCase?
(Image credit: Future / Phil Hayton)

I test thebest gaming handheldcontenders for a living, and the job often means swapping out cases regularly. While I’ve dressed up theSteam Deck OLEDin several different covers over the past few months, the Jsaux Modcase remains my favorite of the bunch, and I have no doubt it’ll bring the same level of functionality and protection to yourAsus ROG Ally. Both portable PCs are slightly different beasts, but the design of Jsaux’s modular add-on will provide a shield in virtually the same way.
The ModCase boasts two main qualities that help it compete with other shells on the market. The first is its large clip-on cover, which contours to the thumbsticks to minimize bulk while completely covering the front of the handheld. The second, and perhaps more interesting, is its modular system at the back that uses a watchstrap-style attachment to hold onto various accessories like the Power Bank included in the deal above.
Hoping to extend your handheld sessions without making your device look like an old-school astronaut? You might want to go check outAsus ROG Ally X pre-ordersto pick up the newest version with a chonkier battery. If you’ve no interest in anything made after the ‘90s, thisGame Boy Color AMOLED touchscreen modmay pique your interest instead, especially if you’ve still got Ninty’s old brick.
