Concluding our review, we found the JSAUX 65Wh battery to be a good product for many reasons. First of all, it extends the running time of your 1st Gen Rog Ally from 1 hour at 25watts operating mode, up to almost 2x, and with lower TDPs you will get even higher differences. Second, it is a fully retail package product, with a second backplate, meaning you don't need to make any modifications to your existing Rog Ally backplate and probably lose your warranty. Third, it also includes a passive heatsink for your NVME SSD and of course tools and all needed screws to operate the change. Lastly, as we mentioned it is a real retail product with supports, an installation guide, and the brand name of JSAUX which has released many peripherals for Steam Deck and Rog Ally.

Passing into the neutral points, the JSAUX 65Wh included aluminum heat spreader for NVME, isn't compatible with 2280 NVME adapters, and JSAUX mentions that using a 2280 NVME adapter will press further the battery cable, we feel that you can use 2280 adapters if you don't use the aluminum heat spreader and don't overtight screws. Lastly, the overall installation process will take around 15 minutes, however, JSAUX has an online guide and a corresponding Video guide that helps a lot with this.

The retail price of the price is at the moment of this writing around $79.99 which can be considered a good upgrade to the stock Rog Ally battery, which should already have shown %wear (ours without much play already showed 10% wear). There are also other solutions with higher capacities (74Wh even 80Wh), that however aren't sold through an official website and cost (~100-120 Euro) much more, than the JSAUX 65Wh battery.

The JSAUX 65Wh battery is a good replacement for all Rog Ally users who simply are jealous of the increased battery that the Rog Ally X offers (almost double), with a good retail price and of course real warranty.
