So Thunderbolt 5 supports up to 240w charging.

Can the Macbook Pro with M4 Pro support 240w? If not, what's the max charging wattage for it?

I think the USB-C/Thunderbolt 5 port is limited to 100w, the MagSafe port is 140w. For whatever reason at least up to M3 Apple has decided to not adopt the 200w USB-C charging spec, but I can't find anything specific for M4 but I'd wager that has not changed.

r/macbookair on Reddit: Maximum charging wattage for m4 MBA

March 27, 2025 -

M4 air comes with a 30w usb c adapter and magsafe cable, so my question is does the usb c to magsafe cable support a 96w brick?

The base comes with 30w, but the 10/10 core units come with a dual USB-C 35w with an option for 70w. So the Magsafe will do at least 70w. Typically you can use higher wattage and the system will just pull the most it can, so if it tops out at 70w and you use a 96w, it might only draw 70w.

it appears the MacBook Air only charges at 70 watt maximum from what I can see. So that is the maximum wattage that will be drawn by the computer. You could have a million watt charger and the MacBook is only going to use 70 watts maximum.

r/macbookair on Reddit: Should I use 35w, 70w or 96w power adapter on M4 MacBook Air

April 30, 2025 -

I selected the 70w adapter but also have a 96w adapter from a MacBook Pro that died and a few dual cord 35w "fast chargers". Now I'm confused over what to use. I mostly leave the MacBook Air plugged into the wall and only occasionally need a fast charge.

M4 Air has a max charging wattage of 70W, so the 96W and 70W will charge around the same. 35W will be slower but if you’re gonna leave it plugged longer it’ll probably be better for ur battery life (o think)

The maximum wattage the MacBook Air can pull from a charger is 70W. So a 96W charger is still charging a MacBook Air at 70W. And it’s only going to pull 70W between 0-50%. After 50% it pulls less, and less, until about 90% and then it pulls very little. So fast charging really only applies to the first half of a battery charge. If you don’t need to fast charge 0-50%, then use a 30W or 35W charger at your regular charging space.

r/macbookpro on Reddit: Which charger should I use if my MacBook Pro is plugged in 24/7?

3 weeks ago -

Hey everyone,

I just picked up a 14-inch MacBook Pro (M4 Pro, 48GB RAM) running macOS Sequoia, and I have a question about charging best practices.

I’m using this MacBook almost entirely as a desktop replacement:

Always plugged in
External monitor
External audio interface
External speakers, keyboard, etc.

The laptop itself mostly just sits closed on my desk. I do occasionally take it with me when traveling, but that’s pretty rare.

My question is about which charger I should be using long-term:

Should I keep using the 96W USB-C power adapter that came in the box?
Or is it better to use a lower-wattage charger, like the one that came with my iPhone 16 Pro, since it’s plugged in all the time?

I’m mainly concerned about battery health and longevity.

Does using a lower-watt charger reduce battery wear, or does macOS handle this automatically regardless of charger wattage?

Would appreciate insight from anyone who’s run a MacBook in a desktop setup long-term. Thanks!

PS: Should I update to Tahoe?

Use the equipment that came from the manufacturer...

use 96 watt, do not use under that because m4 max chip needs a lot of power while using it, dont worry about the battery yor mac can handle it very well if u are worried about battery too much install aldante lock it to %70-%80, if u go under 96 watt it will uses battery and charger at the same time and it will gonna mess with your battery

r/macbookpro on Reddit: What's the minimum wattage for charging a 14 inch MacBook Pro (late 2023, M3 Pro)

June 6, 2024 -

Was wondering because often on Remote Work, and sometimes the amazing battery of the mac isn't enough and I would like to try charging it on the usb or magsafe port with a big powerbank, that I could carry with my backpack (which is kinda big).

So if you got also any advice on some Powerbank that could charge my mac, would be glad to hear it !

I think it depends on the loads you put the machine through. My M3 Max under load discharges when connected to 100W power, so I am pretty sure that in this situation there is no power bank to cover it. But for not under full load and a 14” M3 Pro try to get the biggest wattage you can. If you manage to find something around 50W you probably will be fine unless you do very heavy loads.

The maximum load of 14" M3 Pro is 65W, this is the minimum one to prevent the laptop drain its battery. Otherwise 30/45 should work in light load for charging.

r/macbookpro on Reddit: Got the m4 max 16 inch . Came with the 140 watt charger

May 16, 2025 -

I used to charge my iPhone with the 20 watt fast charger and killed my battery health in a year reached low 80. Used 15 watt and my new phones battery has been good for two years

Basically applying this logic can I use the 96 watt for the MacBook ? I only plan on charging it when I’m not using it and never while I’m using it . Scared it’ll destroy my battery health and don’t want to deal with that later

This is not how it works. The device tells the charger how much voltage and current it wants, not the other way around.

If you use a battery info utility like AlDente or CoconutBattery, you will find that a charging MacBook Pro almost never uses the full wattage of the charger anyway! The Mac is constantly balancing the power draw needs of laptop operation vs charging, so it is always adjusting the ratio of where the charger watts go. All quality chargers today negotiate with the device to not over-draw or under-draw power, and also to not supply any power if they can’t supply the minimum level that device needs (so a phone charger won't try to charge a MacBook Pro). The reason the power adapter is rated for 140 watts is not for normal usage or normal charging. The 140 watts includes a lot of headroom so that it can successfully charge the MBP at its full rate when it is also operating at its worst case power draw: Having to fully power all maxed CPU/GPU cores, while the SSD is also under heavy I/O, while also fully powering USB/Thunderbolt peripherals on all ports, and while the display is set to maximum brightness, etc. For most people, that combination is a very rare occurrence. The MacBook Pro will work fine with somewhat lower wattage adapters but this will not change how charging works and you will notice no difference, especially if the Mac is idle. The only difference with a lower wattage adapter like 96 or 75 watts is if you give it a maxed-out load and the battery is not full, it will have to cut back on the charging rate. So if you use the MBP in a more typical way, which is a certain percentage of CPU/GPU usage with most ports empty or with a low power draw peripheral, with the screen at a medium brightness, then no way is that power adapter drawing 140 watts. Basically applying this logic can I use the 96 watt for the MacBook ? So you can see from the replies that the logic you are using is based on flawed assumptions. It not the year 1975 where an analog battery charger is physically wired to deliver one wattage, and if you plug something in that expects a different wattage, it blows up or something. No, it is half a century later and both the digital devices and chargers are far smarter than that. If you do the research (for example see batteryuniversity.com) you will find that the things that kill li-ion battery life are high heat especially at full charge, and deep charge cycling. Fast charging is not a problem in and of itself, only fast charging all the way to 100% which almost no chargers do because it’s such a bad idea.

Hi guys sorry for my bad English

I have a macbook 16 m1 and it came with 140W power adapter but some when I go out I take with me a 65W power adapter it’s going to effect the battery in any way in short term or long term?

No, but it will impact the charging speed.

It's fine. I only keep a lightweight 30W charger in my bag, I've used it for days and it keeps my M2 16" fully charged. If you're doing intense work, it might use some battery too, but using the battery on it's own uses up battery even more. I did a post on it a few months back on how it worked and how I tested it out. https://www.reddit.com/r/macbookpro/comments/11aj8hq/macbook_pro_max_16_on_a_30w_charger_this_is_how/

r/mac on Reddit: Is it safe to use my 61W MacBook Pro charger with a new MacBook Air M4?

May 27, 2025 -

Hi everyone!
I recently bought a new 13" MacBook Air with the M4 chip. I also have a 2019 13" MacBook Pro, which came with a 61W charger. The new MacBook Air came with a charger that has a US plug, and I live outside the US

Since I already have the 61W charger from my old MacBook Pro, I’m thinking of using it as my primary charger for the new MacBook Air M4
Would that be safe? Can using a 61W charger long-term damage the battery or affect the laptop in any negative way?

Thanks in advance!

It’s fine. Laptop will only take as much juice as it needs.

The 61w charger is fine for the MacBook Air. USB power delivery devices have a handshake process with the charger to only deliver as much voltage as they can handle; and your device will draw as much current as it wants. In this case, both MacBooks can charge at up to 20 volts, and while your MacBook Air charger is probably only 30 or 35 watts, it will happily charge at up to like 70 watts. It’ll charge faster, but it won’t hurt anything.

I got 96w adapter for my macbook pro M3 while I'm thinking when it's charging the adapter is getting so hot, for this I'm thinking right now to change to 70w charger. What your things guys, is it harmful use 96w charger?

I search a lot for this but still i need to know what is the best charging adapter for health macbook pro.

No. Use the 96 W one.

Honestly, just use the MacBook how it makes sense for you. The modern batteries have so much monitoring software that you don’t need to micromanage it. If you want to squeeze out a little bit more battery life out of it my using a lower wattage charger then go ahead. But in the long run it isn’t going to make a major difference. If it is going to be plugged in a lot then limit it at 80%, get the 70w, and rely on charging pass through. But if you are traveling and need to use it get the 96w to charge fast. Just get whatever makes sense for your use case, in the long run using a 96w vs 70w is gonna be at best a few percentage point difference if that

r/mac on Reddit: 90w enough to power 16" MacBook Pro w/ M4 Pro chip?

November 1, 2024 -

My Dell U4021QW has 90w power delivery through a Thunderbolt 3 port - will that be enough juice to keep the 16" MacBook Pro w/ M4 Pro chip well fed? I see from Apple's site that it ships with a 140w power supply so it's an outside chance.

If not, I don't really want to buy a hub or use up a pair of TB ports... :-(

You will find that during "normal" use the machine idles a lot and the 90W are enough to charge. Now if you want to render a 3D movie and you put the system to 100% CPU and GPU usage, then just connect the power brick in addition. But for everyday operation is totally fine. If the performance peaks and 90W is not enough it will just use the battery as a peak buffer and recharge that later.

Can’t speak for the M4 Pro but I have a 16 inch M1 Pro that I often connect to my monitor that delivers 60W over USB-C. Under heavy load it’s still gets charged (very slowly). In comparison my old Intel MacBook Pro lost battery when doing the same. So I am guessing 90W will be enough. ;)

r/macbookpro on Reddit: MBP M4 Pro charger

November 28, 2024 -

Hey. I currently use the lowest end M1 MacBook Air to a 16 inch MacBook Pro with an M4 Pro chip. I see on the apple website these come with a 140 watt USB-c charger. For a while I've been using a 65W anker charger with two usb-c ports and a usb-a to charge both my macbook air, my phone and headphones. I carry it around a lot (to libraries, etc) and take it with me when I travel. I see 100 watt chargers with multiple USB-C ports on amazon that don't seem too much bigger than my current one, could I get away with using a 140w charger for an MBP with an M4 pro or does it have to be 140 watts?

I was able to plug my new M4 MBP into my 65W USB C monitor today. It worked just fine, but if it was under heavy load it might not keep up with the charging.

From what I know, the MBP 16" 2024 comes with a 140W Fast Charging brick. But I have used a 100W charger to charge my MBP 16" 2024 when doing very light tasks such as browsing and doing my office work. I have also have it connected to my Samsung Smart Monitor for the 65W pass through charging. The pass through charging is fine but it is slow. So if you plan on heavy workloads, I'd say a fast charger works but for other tasks a 65W or a 100W charger works fine.

r/MacOS on Reddit: MacBook Pro M4 Pro 14-core wattage requirements

March 9, 2025 -

Just got a MacBook Pro M4 Pro 14-core which comes with a 96 watt AC adapter to replace my MacBook Pro M1. I used the M1 with a Thunderbolt hub, the CalDigit TS3+ which provides 86 watts of power, and I was hoping to be able to continue to use this hub with my new M4 Pro - will using these together cause issues since the TS3+ will not provide quite as much wattage as the Apple AC adapter? I assume so but want to confirm before I go out and need to spend a a couple hundred dollars on a Thunderbolt hub that provides at least 96 watts of power delivery. Help would be much appreciated!

The computer only pulls the wattage necessary. You'll be fine unless you're utilizing 100% of your processor constantly.

86 watt will be plenty for you to charge your Mac while using it, don't worry.

r/mac on Reddit: How much wattage does MacBook use?

November 28, 2025 -

I currently have a MacBook Pro M1 2020 13”, which I’m looking to upgrade from soon, I’ve noticed it takes about 25 watts with spikes to 30 under heavy load, and only about 10 when watching something.

I’ve been looking on Apple’s website to see which power adapter they include but it doesn’t get me very far.

As I’ll beworking off grid mainly on solar, pretty much every few watts count.

If anyone has suggestions or more information about this, or about their own personal device, I’d be enlightened to know the power consumption.

Charge a (or several) large power bank by solar. Use a power bank with USB-C-PD. Use the power bank to charge the MacBook.

https://support.apple.com/en-au/109509 It says 61W or higher. I did some googling and I believe 61 was the original charger. The idea is that it can provide enough power to both run the machine while doing something energy intensive like video rendering plus charge the battery at the same time.

r/macbookpro on Reddit: Is there any disadvantages to using a 61w charger on my M4 Pro?

August 30, 2025 -

Hi there,

Unforunately misplaced the original 70w charger while in the process of moving. I have my old 61w Macbook Pro charger that I've been using for the last couple months. Is there any hardware issues that could arise by this or am I completely fine?

The only issue will be is if you can run the machine at high enough power where you’re actually needing 65 W, and in those moments it’ll need to go to the battery to steal that extra power (which in the long run will slightly reduce your battery life). It would be more of an issue if you were only using a 20 W power adapter and spent most of your time fluctuating between 15 W of usage and 25 W of usage, it would be constantly stealing battery power. My MacBook Pro Max came with 140 W charger, put in my laptop bag. I normally only carry a tiny 35 W charger with me as it’s rare when on the go that my usage exceeds that (I originally only had a 30 W charger, and I liked the one so much I had I bought a spare, but they replaced it with a 35 W charger). The only time I carry 140 W charger with me is when I’m traveling. I might be between flights and want today top my laptop up, or I’m camping and might not have power where I’m at; so if I have an opportunity to plug-in, I want to charge as fast as possible.

As far as I know: MacBook Air (2022 or later) On the MacBook Air, you can fast charge with the following combinations of power sources and cables: 140W USB-C Power Adapter + USB-C to MagSafe 3 Cable or USB-C charge cable 96W USB-C Power Adapter + USB-C to MagSafe 3 Cable or USB-C charge cable 70W USB-C Power Adapter + USB-C to MagSafe 3 Cable or USB-C charge cable 67W USB-C Power Adapter + USB-C to MagSafe 3 Cable or USB-C charge cable (13.6-inch models only) Apple Studio Display + Thunderbolt cable Apple Pro Display XDR + Thunderbolt 3 cable External third-party display capable of delivering 85W + Thunderbolt 3 cable or USB-C cable 14-inch MacBook Pro (2021 or later) On the 14-inch MacBook Pro, you can fast charge with the following combinations of power sources and cables: 140W USB-C Power Adapter + USB-C to MagSafe 3 Cable or USB-C charge cable 96W USB-C Power Adapter + USB-C to MagSafe 3 Cable or USB-C charge cable Apple Studio Display + Thunderbolt cable Apple Pro Display XDR + Thunderbolt 3 cable External third-party display capable of delivering 94W + Thunderbolt 3 cable or USB-C cable 16-inch MacBook Pro (2021 or later) On the 16-inch MacBook Pro, you can fast charge with the following adapter and cable: 140W USB-C Power Adapter + USB-C to MagSafe 3 Cable 140W USB-C Power Adapter + 240W USB-C Charge Cable for MacBook Pro (16-inch, Nov 2023) or later

r/mac on Reddit: Can Apple 61W USB-C power brick charge a 15" M4 MacBook Air faster than its 35W power adapter? Apple says "no", but...

July 24, 2025 -

Update: it charges up to 54 W, apparently.

My place used to be filled with USB-C adapters, but I sold a lot of devices lately and they had to go with em. So now I'm in need of another power adapter, because I only have the 35W Dual USB-C one which came with my 15" M4 MacBook Air.

I've found a dirty cheap (~20 $ w/ extension cable + USB-C to USB-C cable) 61W Apple brick on eBay. Apple states that "fast charging" is possibile on 15" MBA only with a ≥70W power adapter; so my question is: is it possible to charge faster a M4 Air with a 61W brick or is it capped at the same wattage (35) of the dual USB-C adapter? Also, does using a C-to-MagSafe 3 cable instead of a C-to-C make any difference in charging speed? Since, in principle, 61 is more than 35, and the system can draw max 70W, a 61W brick should fast charge the Mac (cause it's way higher than 35!) but Apple says it's not.

Can you help me understand? Also, if you have a 61W and '22 or later MBA it'd be cool to check the power draw with coconutBattery or similar.

Thanks!

Edit: I really don't know why I got downvoted. I thought it could be helpful to shed some light on the ambiguous "Fast charge your MacBook" Apple's support page. Anyway, when I'll have the 61W charger I'll udate you about the real power delivery.

Yes, absolutely. The M4 MacBook Air supports fast charging up to 70W, both through MagSafe and USB C. The system will negotiate the maximum energy it can draw from the charger up to 70W, it absolutely will take the 61W.

BTW you don't need coconut battery to check the power draw. You can use the 'System Information' app which comes with Mac OS
