MacBook charger wattage: which adapter do you need?

Find the model and charging connection first

Open Apple menu › About This Mac on macOS 15 Sequoia, macOS 26 Tahoe or macOS 27 Golden Gate. Note the screen size and chip as well as the name. “MacBook Pro” alone isn't enough: a 13-inch MacBook Pro with M1 and a 16-inch model have different adapter recommendations.

Then check the physical connection. Recent Air and Pro models have MagSafe 3 and can also charge over USB-C. The Neo and older USB-C-only MacBooks use USB-C. An older MagSafe or MagSafe 2 plug is a different connector, and Apple's MagSafe-to-MagSafe-2 converter does not work with MagSafe 3.

Apple's adapter identification page is the reference for charger families. The figures below were checked on 23 October 2026. “Recommended” and “included in the box” are different facts; the latter can change by configuration and country.

MacBook charger wattage by model

Model	Apple adapter guidance	Connection
MacBook Neo, A18 Pro	20 W recommended	USB-C; either port charges
MacBook Air M1, 2020	30 W; Apple also lists its 40 W Dynamic adapter with 60 W Max for this family	USB-C
Air M2–M4, 2022–2025	30 W for 13-inch only, or 35 W, 67 W or 70 W depending on model and intended charging speed	MagSafe 3 or USB-C
Air M5, 13- and 15-inch	Current US specs list the 40 W Dynamic adapter with 60 W Max; fast charge needs 70 W or higher USB PD	MagSafe 3 or USB-C
13-inch Pro M1 or M2	61 W	USB-C
14-inch Pro, 2021 and later	67 W, 70 W or 96 W; match the original configuration or use a suitable higher-rated source	MagSafe 3 or USB-C
16-inch Pro, 2021 and later	140 W	MagSafe 3 or USB-C; fast-charge cable rules below
Intel Air, 2018–2020	30 W, with the same newer 40 W Dynamic alternative listed by Apple	USB-C
Intel Pro, 13 / 15 / 16-inch USB-C models	61 W / 87 W / 96 W respectively	USB-C

For current 14-inch M5 configurations, Apple's tech specs are more specific: M5 uses a 70 W adapter; M5 Pro with a 15-core CPU has 70 W, with 96 W configurable; M5 Pro with an 18-core CPU and M5 Max have 96 W. Don't assume every 14-inch Pro originally shipped with the same brick.

This table is a selection guide, not a minimum needed merely to light the charging symbol. Apple's USB-C guidance allows a higher- or lower-rated USB PD source, while recommending at least its model recommendation for the best charging experience. A low-powered source can be safe yet unable to charge the battery while your workload consumes the available power.

Fast charging needs the right adapter and cable

Apple lists fast charging for Air models introduced in 2022 or later and 14- and 16-inch Pro models from 2021. Its headline is up to 50% in around 30 minutes under its test conditions. That is Apple's result, not a measurement made for this guide, and charge time varies with settings and environment.

Air from 2022: Apple's listed combinations include 70 W, 96 W or 140 W adapters with a USB-C-to-MagSafe-3 or USB-C charge cable. The 67 W combination applies to 13.6-inch models only.
14-inch Pro from 2021: Apple's list includes a 96 W or 140 W adapter with MagSafe 3 or a USB-C charge cable.
16-inch Pro from 2021: use 140 W with MagSafe 3. For the 16-inch November 2023 model or later, Apple also lists 140 W with a 240 W USB-C Charge Cable.

Apple also documents particular display-and-cable combinations on its fast-charge page. Check that list for a powered display rather than assuming any Thunderbolt socket fast-charges every Mac. The Neo isn't included in this fast-charge claim; its specs do not provide a comparable charging-time promise.

Check a replacement cable's power capability as well as its plug. A cable intended mainly for data may not charge the Mac, and the USB-C connector shape doesn't establish its rating. A multiport adapter's headline total is also different from what it allocates to the laptop port while other devices are connected.

Check the connected charger's wattage for free

Apple documents a built-in check: hold Option while choosing Apple menu › System Information, then choose Hardware › Power. Find AC Charger Information and its wattage. This route applies to the supported macOS versions here.

Compare it with the adapter's printed certification label. If the laptop is powered through a display or dock, the information concerns that connection, which can differ from the power supply's overall rating. If no wattage is reported, don't treat a missing value as a zero-watt measurement.

The reported rating still isn't a live meter reading. A “96 W” adapter doesn't necessarily supply 96 W while the computer is idle or nearly full. Some incoming power runs the computer, with the remaining power and charging policy determining what goes into the battery. See MacBook power use for that distinction.

When wattage isn't the problem

A suitable adapter can still show a paused charge because macOS is managing battery wear or temperature. The not-charging guide owns the messages and charging settings; read the battery status before buying a larger brick.

If the connection cuts in and out, inspect the cable and test another compatible one. Apple says to stop using a cable that only works when you move or wiggle it. Keep the adapter ventilated: a unit that gets too warm can shut itself off. Damage, discoloration or sparking away from the wall-plug blades calls for Apple evaluation.

For an employer's Mac or dock, check the approved equipment with IT. For a persistent charging problem, bring the Mac, adapter and cables together for evaluation; replacing one component blindly can leave the actual fault in place.

How Tend helps

Tend's free Battery page, in its Advanced view, shows Power flow: the connected adapter's reported wattage and the watts flowing in when macOS provides them. The model recommendation and live input are different readings. Pro adds the detailed battery record and care reminders; Tend doesn't control charging or raise a dock's output.

Questions

Can I use a higher-wattage charger with a MacBook?

Apple says USB-C-charging Macs can use a USB Power Delivery adapter or display rated above or below the recommended wattage. Choose a compliant source and suitable cable; the rating does not force that full power into the Mac.

Can a phone charger charge a MacBook?

A USB Power Delivery phone charger may provide power, but a low rating can charge slowly or fail to keep up while the Mac is working. Compare it with the model recommendation and check the cable.

Can I charge an iPhone with a MacBook USB-C adapter?

Apple supports charging an iPhone with a compatible Mac USB-C power adapter and the appropriate cable. The adapter’s maximum rating is not power forced into the phone.

Does a 140 W adapter make every MacBook fast-charge?

No. The model, power source and cable must match Apple’s fast-charge combinations. A larger rating alone does not add fast-charge support to a model such as the Neo.
