By device · ASUS ROG Ally
ROG Ally: 65W, and the cable is part of the spec.
ASUS ships a 65W USB-C PD adapter — 20V at 3.25A. That current is above the 3A a plain USB-C cable is rated for, so the Ally is one of the few handhelds where a bargain cable silently costs you 5W of headroom and a Turbo-mode drain.
Numbers first
Maximum input: 65W (20V/3.25A). Protocol: standard USB-C Power Delivery. Both the original Ally and the Ally X negotiate the same 65W contract. In Turbo mode the SoC is allowed a 25–30W package budget, and the screen, fans, SSD and Wi-Fi sit on top of that — which is why a 45W supply keeps the console alive but slowly empties the battery during a demanding session.
Cable: anything above 60W requires a 5A e-marked USB-C cable. A generic 3A cable caps the contract at 60W, and on a device that wants 65W that shows up as a slow drain rather than an error message. Use the ASUS cable, or a marked 100W/5A one — see e-marker cables.
Ports: on the original Ally, charging shares the combined USB-C / ROG XG Mobile connector. On the Ally X there are two USB-C ports, one of them USB4/Thunderbolt-class, and either will charge.
Adapter → behaviour under load
| Adapter | Idle / Silent mode | Turbo mode |
|---|---|---|
| 30W PD | Charges slowly | Clear drain |
| 45W PD | Charges | Slow drain |
| 65W PD + 5A cable | Full speed | Holds and charges — OEM equivalent |
| 65W PD + 3A cable | Full speed | Capped at 60W, marginal |
| 100W multi-port | Full speed | Full speed, plus a dock and a phone |

Don't waste money on
A 140W or 240W adapter. The Ally will not take more than 65W. That money is only justified if a 16″ laptop shares the charger — see best laptop chargers.
Undocumented "gaming handheld" bricks. What you need is a published 20V/3.25A line and a safety listing, which the mainstream GaN brands print openly.
A cheap hub as a dock. Passthrough ratings below 65W turn into mid-game drain. Read the hub's own PD figure before blaming the adapter — more in USB-C laptop charging and slow charging fixes.

FAQ
Can I charge the ROG Ally with a 45W charger?
Yes, and it is safe, but in Turbo mode the console can consume more than 45W. Expect a slow drain during heavy play and full charging when idle or asleep.
Does the ROG Ally need a special cable?
It needs a 5A e-marked USB-C cable to receive the full 65W. A standard 3A cable limits the contract to 60W.
Will a 100W charger damage the Ally?
No. The console requests 65W and the adapter supplies exactly that. Extra capacity sits unused.
Can I charge the Ally X from either USB-C port?
Yes. The Ally X has two USB-C ports and both support charging; the original Ally charges through its combined USB-C / XG Mobile connector.
