Yes, it is absolutely fine to charge your phone using a USB-C MacBook. USB-C is port which was made for this purpose that everything could be charged using one adapter. Now do remember that if your phone supports Power Delivery (PD) charging then it would charge at a very fast rate.

If you have an Android then do note that many Chinese Manufacturers don’t Power Delivery Charging Technology instead, they use their own proprietary charging technology like

  • SuperVOOC - OPPO
  • DART - Realme
  • WARP - OnePlus

So imagine you had an Oppo charger, and you want to charge an iPhone then the iPhone then your iPhone

Yes. It is not only OK, it is what USB-C was designed for. The deaign goal of USB-C was not only a newer/faster communication port, it was also to provide one charger for all your devices.

USB-C, when converted to USB3 or Lightning will output the necessary voltage for the port type, and will supply up to the number of amps that each port was designed to handle. This means that your USB-C charger will be more than capable of charging your phone at the fastest rate it was designed to charge at. All the charging circuita are in your phone, so there is no need for the charger to need to know about

Yes, with caveats.

USB-C with power delivery (generally called USB-C PD) has a complicated negotiation between the power provider and the power receiver and sometimes even the cable. You can get up to 200W of power over USB-C PD.

USB-C without PD provides 1A at 5V which is twice what USB-A is rated for, but various non-standard (and I think some standard) extensions to USB-A have boosted that significantly, but “only” up to 25W or so.

USB-A’s extensions are things like “the data pins don’t pass data but a X ohm resister is placed between pins 3 and 4 to indicate…”. The supply only promises a spec

USB-C without PD provides 1A at 5V which is twice what USB-A is rated for, but various non-standard (and I think some standard) extensions to USB-A have boosted that significantly, but “only” up to 25W or so.

USB-A’s extensions are things like “the data pins don’t pass data but a X ohm resister is placed between pins 3 and 4 to indicate…”. The supply only promises a specific small set of features.

USB-C PD is way more flexible. It provides a much wider range of powers. A supply can offer any mix of powers as opposed to only certain specific presets. PD can adjust dynamically if for example you plug in more devices or the supply is actually a battery it can stop offering higher power settings as the battery drains.

USB-C PD is also complex enough that some early supply’s and receivers got it wrong. Frequently in subtle ways where certain combinations of devices and supplies would destroy one or the other but work fine with other things. The early Google Pixel laptops and Apple’s MacBook no-second-name (sometimes called MacBook One, other times MacBook Adorable) were some of the first few expensive devices to rely on USB-C PD and a lot of early no name USB-C PD supplies were broken and destroyed them. Even some early name brand ones did. The name brand ones mostly paid for the devices they destroyed. The no name ones sometimes did sometimes not.

That use to be quite common and gave USB-C PD a deserved bad name for a while.

It is now pretty rare, but you still sometimes find USB-C devices with improper PD implementations. Most recently the RPi powered by USB-C worked with non-PD supplies, but supplies that offered “too much” power would cause the RPi to decide not to accept power.

So charging a MacBook with a USB-C non PD charger will work but be very very slow. Like if you have it asleep the battery level will go up, if you have the MacBook display on and maybe doing something even something easy the battery will go down but more slowly then without the supply.

Charging a MacBook with a USB-C PD charger that actually properly implements PD will be as above but with more power, so maybe light use will neither charge nor drain the battery. The M1 MacBook for example “only” comes with a 35W charger, so a 20W phone “fast” charger is going to actually be able to keep up with MacBook use as long as you aren’t going full out and stressing both the CPU and GPU at the same time. A 35W phone USB-C PD “fast” charger would make a M1 MacBook Air as happy as Apple’s official charger.

If you look at the MacBook Pro or later M-series CPUs you slide back towards mid-power chargers not being all that fast. Like a 35W charger on a MacBook Pro M2 MAX can keep up with the screen being on and light use, but under heavy use it is very far from keeping up (which is why that laptop ships with a 150W charger).

Only USB-C chargers that improperly implement power delivery and claim to actually implement it will hurt your laptop. Merely getting less power then the laptop wants won’t hurt it unless you get a different voltage then expected and proper PD only ever delivers a negotiated voltage.

Personally even though most of the PD issues are 5+ years in the past I try to stick to brands that have a history of fixing their messes, or are large. So I’ll try’s Anker and RAV because they fixed their messes. I’ll trust Apple because they have a reputation they want to maintain. This is unfair to say Basius and a million AliExpress “brands” that may well be perfect, or at least fix any problems they cause, but I haven’t heard of them before and they have built up no trust.

I wouldn’t trust a $1000-$3000 laptop to them. I might give an older iPhone a shot though…

You may have a bigger appetite for risk than me though. Like maybe you will trust no-name brand if they specifically say “works with (your make and model of laptop)” because they probably tested it if they are putting it in the advertising.

Yes, it is generally safe to charge your phone using a USB-C MacBook charger, provided that your phone supports USB-C charging. USB-C is a universal standard, and most modern smartphones that use USB-C for charging are designed to handle various power inputs.

Here are a few points to consider:

  1. Power Output: MacBook chargers typically have a higher wattage (like 30W, 61W, or 96W) compared to standard phone chargers (which might be around 5W to 20W).

However, devices are designed to draw only the power they need. So, your phone will only take the amount of power it requires, even if the charger can provide more.
  2. Compatibility: Ensure that your phone is compatible with USB-C charging. Most recent smartphones from manufacturers like Samsung, Google, and others use this standard.
  3. Charging Speed: Charging your phone with a higher wattage charger may allow for faster charging if your phone supports fast charging. However, if your phone has a lower maximum charging rate, it will still charge at that rate.
  4. Heat: In rare cases, using a charger with a significantly higher wattage can generate more heat. If you notice excessive heat while charging, it's a good idea to switch to a charger that matches your phone's specifications.

In summary, using a USB-C MacBook charger for your phone is generally safe and can be convenient, especially if you need a quick charge.

No. The default output voltage of the charger is 5 volts. Unless the phone “asks for” a higher voltage, the charger stays at 5 volts. And supplies as much current as it can, up to the limit drawn by the phone. (The phone draws current, the charger doesn’t push it.)

Any 5 volt charger, multi-voltage or just 5 volts, can be used to charge any device that needs at least 5 volts. If the charger can’t provide enough current it just takes longer to charge the battery.

Well, being a new laptop, I got it replaced under warranty and set up the new one. Within a week, the new laptop stopped working, with no usb on the laptop working as a symptom. So I asked the user questions about their use of the laptop. Turns out, she had an old iPod that she used for music on her way to work, plugged into a vehicle usb charger, and when she got to work, or at home, she would plug the iPod into the Laptop to use it.

In looking at the iPod, the battery would not keep a charge for very long, and would be close to or dead when plugging it in. As noted with other answers, chargers are made to supply voltage/amperage at a higher rate than USB outlets on computers/laptops, and my read was that her iPod was trying to draw more amperage than the laptop could supply, and burned out the USB on the laptop.

Now, as noted, most NEW USB outlets try to supply voltage/amperage according the the type of device they see plugged in, and most NEW devices will only draw what they are allowed from the USB, but, bad things can happen.

Lesson, if you are only interested in charging items, use the factory/OEM charger for best operation/fastest charge time. If you are transferring data, or some other reason, plug it into your CPU/laptop, provided the phone has some charge in it.

Assuming this is a charger for a recent mac, with USB-C ports, then yes.

You need a USB-C to Lightning cable, of course.

The charger is capable of providing more power than what the iPhone takes, but that is not a problem. The charger and iPhone will negotiate the power transfer rate, so even if you have an 87 Watt charger, it will probably charge at 18 Watts.

It should just work.

Yes, it’s totally fine, but it will take much longer to charge. Usually it can still charge the laptop to full overnight.

If you are using it while it’s plugged in, most of the time it will slow down battery discharge significantly (for example, if you were using 10% per hour, it could go down to say 3% per hour), but it’s not going to charge the battery unless you are using the laptop very lightly.

A MacBook battery is about 70Whr. A good USB-C phone charger gives you about 15W, so you are looking at about 5 hours for a full charge.

Short answer: yes

Explanation: A laptop USB C charger is a USB C PD capable charger that actually starts a negotiation with the target device in order to determine the device’s power requirements. This means the charger can change is charging levels (think voltages and thus wattage) based on the needs or negotiated power contract by the device. This is what allows some phones or tablets to have super fast charging or fast charging (not to be confused with the Qualcomm fast charging standard).

If you have an older phone or a phone that lacks the circuitry to do a USB C negotiation one of two things will happen

  1. This is usually the most likely one as most phones still implement parts of USB C power standard which results in them being charged at the lowest level 5V at 2A maximum (think old Micro USB or USB A phone charger).
  2. Worst case scenario, the charger does not see any negotiation or proper resistors on the correct lines and defaults to 5V at 500mA (think what your computer can provide when charging through its USB A port).

Yes. The USB specification states that the USB charger must provide a maximum of 5v initially. With USB-C, the device can then negotiate a higher voltage subsequently.

The other thing to note is the current provision. The device will draw as much current as it needs so the charger must be able to provide that or more. Chargers normally have current limiters to stop too much current being drawn but there is no guarantee all chargers have limiters, therefore running the risk of blowing up.

The caveat being that some manufacturers are violating the PD specification and are making power supplies and devices that are USB-C but not PD compliant. These often will neither power nor accept power from devices that are properly PD compliant, or will only do the base 5 volt level.

Absolutely nothing will be hurt, if that’s what you are asking. A USB-C power supply and a USB-C phone should both use something called ‘PD’ (which stands for Power Delivery).

PD is an active negotiation between power source and power consumer, where the two devices tell each other what amounts of power they can give and what amounts of power they need. PD is why that laptop can be charged from USB-C and also can charge something else (like a phone) from the exact same USB-C jack.

So using a USB-C laptop charger to charge a USB-C phone is 100% safe and works just fine. The only small reason not

No, it isn’t harmful.

The laptop power supply will not force power into the phone.

The actual charger is inside the phone (and inside the laptop):

The phone will talk with the power adapter and then they will figure out which is the best charging mode that both phone and power adapter supports. So the phone will not get cooked from being charged from a laptop charger - it’s perfectly fine to use a 100W USB PD power adapter to charge a phone. Or even a 240W power adapter supporting USB PD 3.1.

Thanks for the A2A.

No, it is not harmful to use your USB-C laptop charger to charge your phones. Your phones will take the power they need regardless of what is offered via the charger. In other words, your phone will adapt the power coming in, so you can use your laptop charger, your tablet charger, someone else’s electric shaver charger — whatever.

Yes its fine but it would take a lot longer. I mean ALOT longer. My phone has a 25w charger which is fast but is 3 or 4 times slower than the macbook charger. Imagine using a 5w charger, it would be 15 to 20x slower! Its not worth it.

Profile photo for Chris Summers

Yes it is fine. I do that regularly for years. Your devices have a battery protection circuit that limits and monitors the battery so it only receives what is safe for the battery. You power adaptor has the ability to provide more is requested (like from your laptop) but your device will only take what it needs.

For all intents, a USBc charger, is a USBc charger, is a USBc charger. Part of the protocol is a device stating it's needs and the charger confirming it can meet these needs, or giving a counter offer of what it can produce; which the device either accepts the lower rate, or disables charging.

Having said that, there have been a lot of cables and 3rd party chargers that do NOT follow spec and work correctly.

So long as the charger and device are from a reputable manufacturer (your cell phone and Apple), then you should have no issues.

Profile photo for Paul

Yeah. I just did that now.

The adapter would limit itself to what the phone can handle, which for my iPhone 13 is 20W (rather than the 61W the laptop uses)

Profile photo for Elliot Heasley

Not at all, your phone will regulate the amount of power it accepts from the laptop charger. It will not harm your phone at all. This is one of the reasons I love USB-C…my headphones, laptop, phone, and battery bank all charge with one port so TECHNICALLY I only need my laptop charger to charge all my gadgets :D

Oh heck yeah.

Get a usb c to lightning adapter and plug your iPhone or iPad in.

An iphone 8, X or later will charge at 29 watts for most of the charge, and be the fastest charge possible.

Now, the reason this works, is modern chargers communicate with the charging circuit in the phone, and constantly negotiate the amperage being sent (and in PD and QC 3.0 protocols, the voltage as well). The maximum

Yes, you can use the MacBook's charger to charge your iPhone. Modern iPhones are compatible with the MacBook's USB-C charger, including models up to 140W. The iPhone automatically adjusts the amount of power required according to its needs, so using a higher-power charger will not harm the iPhone. Using a MacBook charger not only provides fast charging for the iPhone, but also reflects the trend of technological integration and sustainable development.

Profile photo for Chris Summers

No, it would be fine. Your smartphone has a battery protection circuit that limits how much electricity that goes to the battery so as to not over charge it or power too much into it. I have used my MacBook power adapter to charge several of my phones. It charges it and when it’s done it stops, that’s it.

Profile photo for N Wong

Yes absolutely!

If you phone has a USB-C connector, make sure you use a proper Type-C to Type-C cable to take maximum advantage of the MacBook charger. It will charge at the maximum capability your phone can accept. Similarly, if you have an iPhone with lightning connector, use a Type-C to lightning cable. If you have an older phone with micro U...

MacBook charger came with USB-C Power Delivery,its a smart charging feature that communicate each other using Power Delivery Protocol, your device will request how much power needed to properly charge, so its gonna be fine because MacBook Adapter 65W use (65W at 20V3.25A with 12V/9V/5V Fallback) and its compactibe and works just fine with most of USB-C Ports (USB-C to Lightning) or USBC to USB-C

Profile photo for Robert the Irrepressible.

Yes if the cable will hook up,the battery should limit how much power it will take.

But hey this is what Apple says: Charge your iPhone with an iPad or Mac notebook power adapter

Profile photo for Bilal Patel

No, not at all. The chargers have smart functionality in which they communicate with the device to be charged to establish the correct charge requirements, and then based on that the charger will adjust it’s output to suit the device.

Profile photo for Bradley Dichter

Perhaps, but without you specifics, I can’t say. The modern MacBook Air uses just a 30W AC adapter to USB-C and this same adapter can be used for a iPhone or Android phone. A common phone charger may be only 20W and that is not enough to charge a USB-C charged MacBook Pro.

Profile photo for Sherman Leung

I don’t know if all laptop chargers can also charge phones but mine can with no problem. A smart charger would negotiate with the phone before providing power to charge. After you plug the charger into your phone, it would take a couple of seconds before charging starts. That couple of seconds is needed for the negotiating process.

Profile photo for Per Westermark

Yes you can. But there are multiple ways USB C supports faster charging speeds and not all devices makes use of all these alterntives.

But nothing will fail and the laptop brick and the phone will manage to figure out the best common standard both can make use of.

Profile photo for Quora User

Although the USB-C plugs are same, the voltage delivery is not and the phone charger will push out a nominal 5 V, the Mac will need a much higher voltage. So it won't work.

Profile photo for Benson Leung

Yes, it should be fine. As long as you can find the cable that connects the USB-C Apple charger to your phone (ie, C-to-C if your phone has a C port, C-to-lightning if your phone has a lightning connector, C-to-MicroB if you have an older phone with USB Micro-B), it should work fine.

By default, the Apple USB-C charger is mandated to support basic 5V power, which all phones should be able to consume.

More advanced phones such as recent Pixel phones, iPhones since iPhone 8 for example, support higher voltage and will support 9V with the Apple adapter, which will safely switch to that voltage afte

Almost certainly, it won’t hurt to try. USB C PD always starts at 5v 2–3A, and the device being charged asks for more if available.

You can even charge your laptop with the phone charger, but what maybe an overnight 4–5 hours charge could take 3–5 days….

Profile photo for Scott Bohlen

Yes, the usb-c/thunderbolt 3 Adapters first the newest Mac laptops work very well as a charger for iOS devices. Just get a usb-c to lightning cord and you are ready to go

Profile photo for Kirn Gill II

Yes! It’s perfectly fine. All USB chargers, including USB Type C laptop chargers, all start at a normal 5 volts, only going higher after first connecting at 5 volts and negotiating a higher voltage. If the connection is interrupted, however briefly, the charger returns to 5 volts. This is because 5 volts is the original USB voltage and thus guaranteed to work - and safely so - with everything.

Profile photo for Perry

Assuming your laptop charges via USB-C, it should be fine. I would check the voltages before hand if they are too high(9V is usually the highest voltage). But just in case, I would personally not do so unless your charger is one of those third party multi port or multi device charger.

Profile photo for Phil Lutz

Yes… but only if charger is 5 volts. Use phone to take photo of back of charger then make the photo larger and you can see the voltage number.

Profile photo for Quora User

Sure. The ECU inside the phone can “negotiate” with the macbook charger on a possible current to charge it.

Profile photo for Mihai Voicu

Normally it should be safe to do it as long as the cable fits without forcing.

The phone will draw the current it needs, even if the charge can provide more than that. The charger only sends higher than 5V voltage if the phone/laptop is specifically requesting it (over the wire).
