MacBook Pro 16” Guide

MacBook Pro 16” Charger UK — The Right Wattage Explained

The MacBook Pro 16” with M3 Pro or M3 Max requires 96W–140W for full-speed USB-C charging. A 100W USB-C PD 3.1 desktop charger delivers near-identical charge times to Apple's 140W MagSafe — over a standard USB-C cable, no MagSafe adapter required. It also charges your phone, tablet, and earbuds simultaneously from one desktop unit.

65W Charger
Charges under load — ~50% max speed. Fine overnight, slow at desk.
100W USB-C PD 3.1
0–50% in ~45 min. Full desk speed. Charges 3 devices at once.
140W Apple MagSafe
Marginally faster than 100W. MagSafe only — not universal.

100W over USB-C vs 140W MagSafe

In real-world tests, a 100W USB-C PD 3.1 charger charges the MacBook Pro 16” only 8–10 minutes slower over a full 0–100% cycle compared to Apple's 140W MagSafe. The key advantage of USB-C: one cable charges your laptop, Samsung, and iPad — no proprietary connectors required.

M3 Pro vs M3 Max Power Draw

The M3 Pro chip draws up to 100W under CPU+GPU load; the M3 Max up to 140W at peak. For M3 Pro owners, a 100W USB-C charger covers every scenario. M3 Max owners working with intensive GPU tasks (video export, ML) may notice occasional battery dip — for those users, pairing with a MagSafe 140W alongside a USB-C 100W is ideal.

E-marker cable required: A 100W charger needs an E-marker USB-C cable to deliver the full 100W — standard cables without an E-marker chip cap at 60W. Our SmartGear 240W USB-C cable includes the E-marker chip and is available separately or bundled with the desktop charger.
