If you’ve been keeping an eye on the handheld gaming world, you’ve probably come across the Asus ROG Ally—a portable powerhouse mini gamind pc that has taken South African gamers by storm. It's sleek, powerful, and designed to handle demanding AAA titles on the go. But like any high-performance device in a compact form, there's one common complaint among users: battery life.
Asus ROG Ally Battery
In this post, we’ll break down the ROG Ally’s battery limitations, discuss the risky trend of internal battery mods, and—most importantly—introduce a smarter, safer solution: the Romoss PMT40 EZCarry Pro 40000mAh 65W Fast Charge Power Bank, now available at Buysave.

Why the ROG Ally is Worth It—But Not Without Its Flaws
Let’s start by giving credit where it’s due.
The Asus ROG Ally is not your average handheld console. Powered by an AMD Ryzen Z1 or Z1 Extreme processor, it boasts enough muscle to run PC-grade games at impressive frame rates. It features a 7” FHD touchscreen with 120Hz refresh rate, and supports Xbox Game Pass, Steam, and even emulation platforms (playing PS3 or Switch games is possible)—making it incredibly versatile.
But with great power comes great… battery drain.
Users often report much less than 2 to 3 hours of real-world gaming, depending on the settings and game intensity. For lighter tasks or indie games, you might stretch that to 4 or 5 hours. But if you're running something like Elden Ring or Cyberpunk 2077 on Turbo Mode? Expect to reach for the charger in no time.
The Temptation of Internal Battery Mods (And Why You Should Think Twice)
A growing number of ROG Ally owners have turned to DIY internal battery modifications, replacing the stock Asus ROG Ally battery with a higher-capacity alternative to extend playtime.
Sounds like a great idea, right?
Not quite.
Here are a few reasons why this route is risky besides the fact that you playing with the main power source of the complex gadget:
1. It Voids Your Warranty
Asus has made it very clear—opening up the Ally and tampering with the internals immediately voids your warranty. So if anything goes wrong, whether related to the mod or not, you're on your own.
2. It’s Not Plug-and-Play
Battery mods often require precise disassembly, soldering, or re-routing cables. This isn’t a simple swap-out like with older devices.
3. Safety Risks
Modding a lithium-ion battery, especially one inside a high-performance gaming device, introduces risks like overheating, battery swelling, or even fire hazards if done improperly.
4. Incompatibility
Not all third-party batteries play well with the Ally’s software or charging system. This can lead to unexpected shutdowns or degraded performance over time. I'm sure you have heard before how 3rd party laptop batteries or even 3rd party ink for printers never work as well as the orignals 90% of the time.
The Better Solution: Romoss PMT40 EZCarry Pro 40000mAh Power Bank

Instead of opening up your device and rolling the dice with your warranty, the smarter move is to power your ROG Ally externally—and Romoss has the perfect tool for the job.

Real-World Use: How It Fits into Your Gaming Life
Picture this: you’re heading out for the weekend. Maybe you’re driving or flying to Cape Town or Durban or camping in Drakensberg. Your ROG Ally is fully charged, and your Romoss PMT40 is packed. That’s easily 8 to 10 hours of gaming on demand—no wall socket in sight.
Even better? You can keep your phone, tablet, and headphones topped up too.
And when you get home? No worries about having voided warranties, damaged internals, or risky mods. Just check when flying if they have any issue carrying on a powerbank to the plane.
Price vs. Peace of Mind
Yes, the Romoss PMT40 isn’t the cheapest power bank on the market. But think of it as insurance—not just for your ROG Ally’s warranty, but for your gaming lifestyle.
At under R1500, it’s a small investment compared to the R13,000+ cost of the Ally itself. And since it works with all your devices, it's an accessory that keeps delivering long after your current handheld is replaced.
Don't Mod—Power Smart
To wrap up: the Asus ROG Ally is one of the most exciting gaming devices available in South Africa today. But the battery life? It’s an obvious weak point.
Instead of opening your device, voiding your warranty, and taking on risk, the better choice is clear:
💡 Go external. Go smart. Go Romoss.
