Reddit user converts eBike battery into 24-hour ROG Ally power bank
In what is again a fine addition to the cursed images of the tech internet, a user on Reddit has successfully hooked up their eBike battery to their ASUS ROG Ally X. The results are pretty amazing, as user DoggoLord27 now probably has the biggest power bank available for an ROG Ally. Emphasis on "probably," because the r/ROGAlly subreddit has proven time and time again that the users here are determined to make their respective ROG Ally last the longest.
The original poster took a big battery from an electric bike, which normally puts out a high voltage (48 volts), and made a special adapter that turns this power into the kind that things like the ROG Ally gaming device can use through a regular USB port. This adapter makes sure the electricity coming from the bike battery is changed to the right amount that won’t damage the gaming device.
With this setup, one can use the huge battery to play games for as long as 24 hours without needing to plug into a wall. The OP mostly did this as a fun DIY project, showing it’s possible to use a large e-bike battery to keep gaming devices running much longer than with standard portable chargers.
The comments in the subreddit offered a mix of opinions. While one user, u/lildinkyactivist, claimed, “I just hook mine up to a Jackery,” which is equally impressive if true, u/Aflux added that this mod seems like a cool project for a power outage.
Some raised safety concerns, with u/Competitive-Will-701 asking, “Are you doing a voltage step-down? Because 48 volts can do some damage to your battery,” and the OP replying that a special block handles it, as it steps down up to 72V to 12V. Still others, like u/kellven, were simply impressed, saying, “This is a really cool idea.”
Nonetheless, instances of user creativity like this really go to show how tech is actually used in the real world. In an age where companies are even extending their control to the ports of handheld consoles that users legally own, it’s refreshing to see a device seemingly made to withstand serious user experimentation.
