Which charger wattage fits a 14-inch MacBook Pro and an iPhone together?

Main answer · Wecent Editorial Team

Short answer: Check which adapter the MacBook shipped with; Apple has shipped 14-inch MacBook Pro models with 67W, 70W and 96W adapters depending on the chip and configuration. Add about 20–30W for the iPhone. A 100W two- or three-port USB-C charger is usually a good fit, provided the laptop port still gets enough power when the phone is connected. Check Apple’s specifications for the exact model and the charger’s port allocation.

Start with the laptop

Apple lists the included adapter in each model’s technical specifications. The laptop charges on lower-wattage USB-C PD chargers too, just more slowly, and may discharge under heavy load. Apple’s fast-charge feature for some models requires a higher-wattage adapter; check Apple’s support pages for the specific model.

Add the phone

Recent iPhones charge fast with USB PD at around 20W and above; Apple’s pages describe fast charging to about 50% in around 30 minutes with a 20W or higher adapter, with figures varying by model. Budget 20–30W for the phone.

Check the split, not the total

A 100W multi-port charger doesn’t give 100W to the laptop when a phone is also connected. Typical splits might be 65W + 30W or 70W + 30W, but designs vary. Look at the port allocation table: what does the laptop port get with the phone connected?

Cables

• For more than 60W to the laptop, use a 5A e-marked USB-C cable.
• MagSafe 3 cables work with USB-C PD chargers, and Apple sells USB-C to MagSafe 3 cables.
• The iPhone needs a USB-C cable (iPhone 15 and later) or USB-C to Lightning.

Recommendations by setup

• Laptop with a 67W or 70W adapter + iPhone: a 100W two-port charger with roughly 65–70W on the laptop port when shared.
• Laptop with a 96W adapter + iPhone: a 100W charger works but the laptop gets less than its adapter when shared; consider a 140W charger for full speed.
• Travel: a compact 65W–100W GaN charger is a fair compromise; charging may be slower under heavy load.

Heat and placement

High-power multi-port chargers get warm when running two devices. Use them on an open surface rather than behind furniture or under bags.

What we confirm before recommending

Confirm with Wecent the per-port output with two devices connected for each model. Listings should state “laptop port up to X W when used with a phone” rather than only the total.

Where this answer says confirm with Wecent, the detail is not published on the product page and has to come from the datasheet or the factory. General facts come from the standards bodies, regulators or device makers named in the text.
