Wattage · Apple's dual-port number
35W adapters: one number, two ports, one split worth knowing.
Apple sells 35W in two bodies — the compact dual USB-C and the folding-pin dual USB-C — and both share a rule that decides whether this adapter suits you: 35W is the total, not the per-port figure.
What happens when you plug in the second device
| Ports in use | Output | Practical effect |
|---|---|---|
| One port | Up to 35W | Full speed for a MacBook Air, iPad Pro or any phone |
| Both ports | Roughly 17.5W + 17.5W | Two phones charge well; a laptop drops to a trickle |
That split is the entire buying decision. If you charge two phones or a phone and a watch overnight, 35W dual is close to ideal. If you charge a laptop and a phone together, the laptop gets less than a 20W brick would give it, and you should be looking at 65W instead, where a proper power-sharing controller keeps the laptop above 45W.
Who 35W is actually for
MacBook Air owners who travel light. On a single port it exceeds the 30W brick the Air ships with, so charging is at least as fast as stock, and the second port covers the phone at night. iPad Pro plus iPhone. The tablet's roughly 30W appetite is met on one port alone; shared, both devices still charge at usable phone-class rates. Two-phone households. One wall socket, two full 17.5W streams, no hub required.
It is a poor fit for a Nintendo Switch (39W at 15V/2.6A), a Steam Deck (45W) or any Pro-class laptop. Those belong at 45W and above.

Sizing up, sizing down
Choose 30W instead if you only ever charge one device — it is cheaper, smaller and gives that device the full rail set including 20V. Choose 40W if you want Apple's newer dual-port part with a dynamic single-port boost, or 45W for handhelds and Galaxy Ultra PPS. The two direct comparisons are Apple 30W vs 35W and 35W vs the 40W Dynamic, and the model-specific detail sits on the Apple 35W dual USB-C page.
FAQ
Does the 35W adapter give 35W to each port?
No. 35W is the total for the adapter. With both ports occupied it divides to roughly 17.5W each, which is fine for two phones and too little for a laptop.
Is 35W better than 30W for a MacBook Air?
On a single port, slightly — you get a few extra watts and a second socket. Apple's fast-charge claim for the Air is tied to a higher-wattage adapter, so this is a convenience upgrade rather than a speed one.
Can a 35W charger run a Nintendo Switch dock?
No. The dock needs 39W delivered as 15V at 2.6A. A 35W adapter cannot supply that profile, and docked play will drain the console during use.
