Leak: the Asus ROG Ally X will have twice the battery at 80Wh and two USB-C ports

While we already knew the Ally X was shooting for double the battery life by including a larger pack, VideoCardz has leaked marketing materials that confirm it’s literally doubling the capacity to 80 watt-hours, up from the original 40Wh pack. If true, that would be the largest battery we’ve seen in a handheld, surpassing the boutique Ayaneo Kun’s 75 watt-hour pack.

And yet, the Ally X only weighs an additional 70g (2.5oz) and is just 5mm thicker, a bit thinner than my hands-on estimate. It’s 36.9mm (1.45 inches) thick in total, versus the 32mm (1.27 inches) of the original.

That’s partially due to a thinner fan design: 23 percent smaller, with 50 percent thinner fins, according to the leak, yet with 10 percent increased airflow.

Aside from battery, the most welcome spec might be the addition of a second USB-C port with USB4 speeds. VideoCardz says it replaces the proprietary eGPU port that Asus included previously but doesn’t say if we can charge from both the top and bottom now. (I would expect so since Asus taped up both the top and bottom of the engineering prototype I touched to keep me from sussing ports out.)

As we’ve reported, the Ally X shouldn’t have much increased performance over the original, with the same Ryzen Z1 Extreme chip and seven-inch 120Hz VRR screen, but VideoCardz also corroborates the rumor that it’ll come with 24GB of faster LPDDR5 memory, giving it an additional 8GB of overhead to share with the GPU that could possibly lead to a slight improvement in games.

Asus didn’t immediately respond to a request to confirm the specs.
