Since the Asus ROG Ally and ROG Ally X are such powerful devices, it's not all that surprising that they drains their batteries rather quickly. You can easily improve upon this by purchasing one of the best ROG Ally power banks to juice the handheld back up so you can keep gaming. However, you need to make sure that you get the right battery otherwise it won't be able to keep up with the Ally's power consumption needs. This is especially true if you're wanting to play games in ROG Ally's Turbo mode as this requires at least a 65W power flow.
Below, I've listed the very best ROG Ally power banks available right now as well as go over what to look for in a ROG Ally battery pack. You might also want to check out the best ROG Ally microSD cards or learn how to upgrade an ASUS ROG Ally SSD while you're at it.

UPDATED March 26, 2025: I added the JSAUX ModCase and Power Bank Kit (which I've reviewed) and replaced the Baseus power bank with a newer version.
Best ROG Ally power bank overall
Thanks to its reliable devices and decent pricing, Anker is my most trusted power bank brand on the market. This 87W max output power bank and power adapter combo will allow you to charge up the ROG Ally even in Turbo mode. The bank features two USB-C and two USB-A ports and has a high 25,600mAh capacity to last you a long time before running out of juice. It's the perfect ROG Ally travel accessory.
Best budget ROG Ally power bank
This is a popular power bank thanks to its budget pricing and powerful delivery. It offers 25,000mAh at 65W output making it the perfect ROG Ally companion. There are two PD USB-C ports (65W and 35W) and a 22.5W USB-A port to help you connect to the handheld and your favorite accessories. The large screen also makes it easy to see how much power the battery still contains.
Best ROG Ally X power bank and case bundle
Protect your ROG Ally X and make it easier to keep it charged up with this ModCase and power bank kit. It comes with a strap that you can use to connect the 65W 20,000mAh battery to the back of the handheld casing for more convenient travel. Note that it doesn't work with the original ROG Ally. If you're interested, you can check out our JSAUX ModCase ROG Ally X Bundle review for more details.
Best hybrid power bank
As I said before I love Anker, and the 733 Power Bank is a phenomenal option specifically for ROG Ally since this battery pack can plug directly into an outlet and charge itself back up while also charging up the gaming handheld. That's what makes it a hybrid. It features two USB-C ports (one in and out, the other just out) and a USB-A port and offers 10,000 mAh. It's a bit pricey, but worth it for its convenience.
Best LED display power bank
This 145W 25,000mAh power bank won't break the bank, and its two useful USB-C ports and USB-A port will allow you to charge up the ROG Ally and any accessories you might need simultaneously. The helpful LED display lets you know how much juice is left in the pack so you can easily tell when it needs to be charged back up.
Best thin ROG Ally battery pack
The Baseus Blade is the widest and flattest power bank on this list, but it's still small enough that it's easy to store in a pocket, backpack, or purse. With a 20,000mAh capacity and 100W power output it's more than capable of keeping up with the ROG Ally. It features two USB-C in/out ports and two USB-A out ports. Keep track of recharging time, battery level, and charging power via the helpful screen.

The ROG Ally is an amazing gaming handheld, but it eats battery life like nobody's business.
For this reason, it's smart to grab a battery pack if you want to play for long stretches or if you see yourself playing the handheld on the go.
You want to look for a battery pack with a high mAh capacity (preferably around 20,000mAh or higher), so it will last longer.
Meanwhile, you need to get a battery pack that offers an output of at least 65W or higher to keep up with the ROG Ally and Ally X's power needs.

If you want the very best option, go for the Anker PowerCore A1291. It comes with a USB-C cable, offers an 87W max output that can easily handle the Ally's Tubro mode, and has a high 25,600mAh capacity that will last for long stretches of gaming time.
Plus, it comes with a useful power adapter to help you charge the battery or your ROG Ally up faster. It's everything you need whether you're taking the ROG Ally on a trip or are simply out running errands.
Meanwhile, if you're looking for a cheap but reliable budget option, then I highly recommend the INIU Power Bank 65W 25,000mAh. It costs less than many other devices on this list but still has the power and capacity to suit the ROG Ally.
Alternately, if you're looking for something that provides plenty of information and charging convenience while still being relatively thin, then the Baseus Blade is the power bank to buy.
It has an impressive 100W output with a 20,000mAh capacity. Thanks to the helpful LED display, you can always tell how much battery life is left in it, what the charging power is, and what the estimated recharging or charging time is.
Remember, at the very least, you need to get a power bank that offers 65W power flow to keep up with the ROG Ally or Ally X's needs.
Otherwise, you won't be able to play and recharge the gaming handheld at the same time. The higher the capacity (mAh), the more recharge time you'll get from a battery pack.
Can you use a power bank with ROG Ally and ROG Ally X?
Yes. You can charge up an ROG Ally or ROG Ally X using a power bank as long as the power bank offers at least a 65W power flow. This provides enough power to charge the device while you play.
What is the best power bank for ROG Ally?
There are many options available. Our favorite one doubles as a power bank and a pass through wall charger. That way, even if it's out of juice, you can still use it to provide power to the ROG Ally or Ally X.
How long does ROG Ally last with a power bank?
This will depend on the capacity of the power bank that you are using. The higher the capacity, the longer your Ally will be sustained for. In general, the ROG Ally can play more demanding games at max TDP for about 51 minutes. Meanwhile, at those same settings, the Ally X can last for about two hours and 10 minutes. If you have the TDP and screen brightness at lower settings, you can play both devices longer.
Is it okay to play ROG Ally while charging?
Yes, it certainly is. The ROG Ally will get a bit hotter around the USB-C port if it is plugged in while you play, but it won't hurt the system. You can still play games this way.
