Can I Charge My MacBook with My Phone?
Are you wondering if your MacBook can be charged using your phone’s cable and charger? The answer is yes, but with some caveats. In this article, we’ll explore the compatibility and feasibility of charging your MacBook using your phone’s cable and charger.
Understanding USB Power Delivery (PD)
Before diving into the question, let’s take a brief look at USB Power Delivery (PD). USB PD is a technology that allows devices to share power over a single cable, up to 100W of power. This is useful for charging larger devices like laptops, tablets, and smartphones. However, not all devices support PD, and the speed and power limits vary.
Can I charge my MacBook with my phone using USB PD?
The answer is yes, but with some conditions. Yes, you can charge your MacBook with your phone using USB PD, but only if your phone supports the same standard and has enough power capacity. Here are the key details:
- Apple supports USB PD: Apple’s M1 MacBook Air and MacBook Pro (M1, M2, and M2 Pro) models support USB PD, but only up to 48W power output. However, the M1 MacBook Air and MacBook Pro (M1, M2, and M2 Pro) do support USB PD with a 1.2A power output, which is sufficient for charging a MacBook.
- Phone compatibility: If your phone supports USB PD, you can use it to charge your MacBook, but only if it has enough power capacity. The most common phones that support USB PD are:
- iPhones (13 and later)
- Samsung Galaxy phones (s, Note, and series)
- Google Pixel phones
- OnePlus phones
- Power output limitations: Even if your phone supports USB PD, the power output is limited to 10W or 20W, depending on the model. This means that if you want to charge your MacBook at its maximum 240W power output, your phone won’t be able to provide it.
Can I charge my MacBook with my phone using USB-C PD?
Now, let’s talk about USB-C Power Delivery (PD). USB-C PD is a newer technology that offers faster charging speeds than traditional USB PD. However, it also has some limitations.
- Apple supports USB-C PD: The M1 MacBook Air and MacBook Pro (M1, M2, and M2 Pro) models support USB-C PD, but only up to 100W power output. However, the M1 MacBook Air and MacBook Pro (M1, M2, and M2 Pro) do support USB-C PD with a 1.1A power output, which is still sufficient for charging a MacBook.
- Phone compatibility: As with USB PD, the most common phones that support USB-C PD are:
- iPhones (13 and later)
- Samsung Galaxy phones (s, Note, and series)
- Google Pixel phones
- OnePlus phones
- Power output limitations: Similar to USB PD, even if your phone supports USB-C PD, the power output is limited to 10W or 20W, depending on the model. This means that if you want to charge your MacBook at its maximum 240W power output, your phone won’t be able to provide it.
Table: USB Power Delivery (PD) Compatibility Chart
| Device | USB Power Output (W) | USB Power Delivery (PD) Support | Speed Limitation |
|---|---|---|---|
| Apple M1 MacBook Air | 48W (PD) | Yes, 1.2A (PD) | No |
| Apple M1 MacBook Pro | 48W (PD) | Yes, 1.2A (PD) | No |
| iPhone 13 | 20W (PD) | Yes | No |
| Samsung Galaxy S21 | 25W (PD) | Yes | No |
| Samsung Galaxy Note 20 | 25W (PD) | Yes | No |
| Samsung Galaxy Note 10 | 20W (PD) | Yes | No |
| Google Pixel 4 | 15W (PD) | Yes | No |
| Google Pixel 3 | 12W (PD) | Yes | No |
| OnePlus phones | 18W (PD) | Yes | No |
Conclusion
In conclusion, you can charge your MacBook with your phone using USB PD, but only if your phone supports the same standard and has enough power capacity. While USB-C PD offers faster charging speeds, it also has limitations in terms of power output and speed.
Before using your phone to charge your MacBook, make sure it supports USB PD or USB-C PD, and the phone has enough power capacity. If your phone doesn’t support USB PD or USB-C PD, you may need to use a different cable or device.
Tips and Tricks
- Use a USB-C cable with a USB-C Power Delivery (PD) adapter to take advantage of faster charging speeds.
- Use a USB Power Delivery (PD) charger to charge your phone, and then plug it into your MacBook.
- Keep in mind that even with USB PD, the power output is limited to 10W or 20W, depending on the model.
