You can use any USB-C cable with a MacBook, but not every cable will charge it at full speed
MacBooks charge through USB-C, and any USB-C cable will physically fit and transfer power. However, the cable's power rating matters. A cable rated for only 5W or 15W will charge your MacBook slowly or not at all while you use it. To charge at the speed Apple designed, you need a cable rated for at least 60W (for smaller models like the 13-inch MacBook Air) or 96W to 140W (for larger models and Pro versions). The cable itself is just the connector — the real power comes from the adapter plugged into the wall.
Apple's own cables work, but they cost $19 to $29. Third-party cables from brands like Anker, Belkin, and Nylon work just as well if they carry the same wattage rating and meet USB-C standards. The difference is usually just price and durability. You do not need "special" cable — you need the right power rating for your model.
Key Takeaways
- Any USB-C cable fits a MacBook's charging port, but the cable's wattage rating determines charging speed.
- MacBook Air models need at least 60W; MacBook Pro models need 96W to 140W depending on the year and screen size.
- Third-party cables from reputable brands work as well as Apple's cables if they meet the same wattage and USB-C standards.
- The power adapter plugged into the wall matters more than the cable itself — a weak adapter will slow charging even with a good cable.
How to find your MacBook's power requirement
Your MacBook's model determines how much power it needs. Go to the Apple menu in the top left, select About This Mac, and note the model name and year. Then cross-reference it with Apple's official specs or your original power adapter.
MacBook Air models from 2018 onward charge at 45W to 60W. The 13-inch Air uses 45W; the 15-inch uses 60W. MacBook Pro models are higher: the 14-inch uses 96W, and the 16-inch uses 140W. If you have an older model, check the wattage printed on the original adapter that came in the box — it will say something like "45W" or "96W" near the plug.
You can charge with a lower-wattage cable and adapter, but the MacBook will charge slowly or stay at the same battery level while you work. You cannot damage the MacBook by using a lower-wattage cable — it simply will not deliver power as fast.
Why the adapter matters more than the cable
The power adapter — the brick that plugs into the wall — is what determines how much power flows through the cable. A 60W adapter will never deliver more than 60W, no matter how good the cable is. The cable is just the path. If you buy a high-wattage cable but keep using a 30W adapter, you will still charge slowly.
Apple's adapters are expensive ($49 to $99), but third-party adapters from Anker, Belkin, and other brands often cost less and deliver the same wattage. Look for adapters that say "60W USB-C" or "96W USB-C" — the number tells you the maximum power. Pair it with any USB-C cable rated for that wattage or higher, and you are set.
Third-party cables versus Apple's cables
Apple's USB-C cables cost $19 for a 1-meter cable and $29 for a 2-meter cable. They are well-made and durable, but they are not the only option. Anker, Belkin, Amazon Basics, and other brands sell USB-C cables for $8 to $15 that work identically for charging.
The main differences are length, build quality, and warranty. Apple's cables come with a one-year warranty. Third-party cables often come with longer warranties (Anker offers two years on many models). If you want a longer cable or a braided design that resists fraying, third-party options give you more choices at lower prices. The charging performance is the same as long as the wattage rating matches.
One caveat: not all USB-C cables are created equal. Cheap cables from unknown sellers on marketplaces sometimes fail or do not deliver the rated wattage. Stick to established brands with customer reviews, and check that the cable explicitly states its wattage rating.
What happens if you use the wrong cable or adapter
Using a cable or adapter rated below your MacBook's needs will slow charging. A 30W adapter on a 60W MacBook Air will charge it, but it might take twice as long. If you are using the MacBook while charging, a weak adapter may not deliver enough power to charge at all — the battery will stay flat or drain slowly.
Using a cable or adapter rated higher than your MacBook needs is safe. A 140W adapter will not overcharge a 60W MacBook Air. The MacBook only draws the power it needs, so extra capacity does not cause damage. This is why many people buy one high-wattage adapter and use it for multiple devices.
The only real risk is buying a cable or adapter from an unknown brand that does not actually deliver the wattage it claims. This can cause slow charging or, in rare cases, overheating. Stick to cables and adapters from brands with established reputations and customer reviews.
Cables for specific MacBook models
| MacBook Model | Minimum Cable Wattage | Recommended Adapter |
|---|---|---|
| MacBook Air 13-inch (2018 and later) | 45W | 45W or 60W USB-C adapter |
| MacBook Air 15-inch (2023 and later) | 60W | 60W USB-C adapter |
| MacBook Pro 14-inch (2021 and later) | 96W | 96W USB-C adapter |
| MacBook Pro 16-inch (2021 and later) | 140W | 140W USB-C adapter |
If your MacBook is older than 2018, it may use USB-C but with different wattage requirements. Check the original adapter or the Apple Support website for your specific model year.
Frequently Asked Questions
Can I use an iPad or iPhone charger to charge my MacBook?
Only if it is a USB-C adapter rated for at least 45W. Most iPad and iPhone chargers are 20W or less, so they will charge your MacBook very slowly or not at all while you use it. A newer iPad Pro with a 35W or higher USB-C adapter will work, but it is still slower than a dedicated MacBook adapter.
Do I need to buy Apple's cable, or can I use any USB-C cable?
Any USB-C cable works as long as it is rated for the wattage your MacBook needs. Apple's cables are reliable, but third-party cables from Anker, Belkin, or Amazon Basics perform identically and often cost less. Check the wattage rating on the cable before buying.
Will a higher-wattage cable or adapter damage my MacBook?
No. A 140W adapter will not overcharge a 60W MacBook Air. Your MacBook only draws the power it needs, so extra capacity is harmless. This is why many people use one high-wattage adapter for multiple devices.
Why is my MacBook charging slowly even though I have a new cable?
The adapter is likely the bottleneck, not the cable. Check the wattage printed on your power adapter. If it is lower than your MacBook's requirement, upgrade the adapter. The cable is just the connector — the adapter determines how much power flows through it.
Can I charge my MacBook with two USB-C ports at the same time?
Yes, if your MacBook has multiple USB-C ports (most Pro models do). You can plug in two adapters to charge faster, but this is rarely necessary. One adapter rated for your MacBook's wattage will charge it at full speed.
