Best USB-C Cables for MacBook Pro and MacBook Air
Is your MacBook charging slowly even on a fast charger? The cable is usually the bottleneck — a phone cable caps your laptop well below full speed, no matter which brick you plug it into.
Quick Answer: For a MacBook, buy a USB-C cable rated at or above the laptop's full charging wattage. MacBook Air needs 100W and 5A with an E-Mark chip, and MacBook Pro 16-inch needs 240W USB PD 3.1. If the cable rating is below the model, charging slows even with a fast charger.

Why Your Current USB-C Cable Might Not Be Fast Enough
MacBook Air (M3/M4) charges at up to 67W. MacBook Pro 14-inch peaks at 96W to 140W depending on the adapter, and MacBook Pro 16-inch uses 140W. Most USB-C cables were built for data transfer or low-wattage phone charging. Their power conductors are too thin to carry 100W or more, so they limit current — usually to 18W to 60W.
The fix: Use a cable rated at 100W minimum for MacBook Air, and 240W for MacBook Pro.
MacBook Air: PowerCord 100W Braided
The AK NextG PowerCord 100W Braided is rated 100W at 5A, with a nylon braided jacket, an E-Mark chip, and FCC + CE certification. That covers MacBook Air's full 67W with headroom to spare, and it also fast-charges iPhone, iPad and Samsung phones. Available in 1M and 2M lengths. $12.99
MacBook Pro 14-Inch: The 100W vs. 140W Question
For everyday desk charging, a 100W cable keeps the MacBook Pro 14-inch at full charge during normal workloads. For heavy rendering or sustained loads on the larger adapter, step up to a 240W cable so the cable never becomes the ceiling.
MacBook Pro 16-Inch: You Need 240W
The AK NextG PowerCord 240W is rated to USB PD 3.1 at 240W — the ceiling for the standard — at 5A, in a soft silicone jacket, 1M, in six colors. It delivers the Pro 16-inch's full 140W and stays future-proof for the next laptop too. $12.99
The Desk Upgrade: PowerCord 240W Braided + Stand
The AK NextG PowerCord 240W Braided + Stand delivers the same 240W at 5A over 1.5M of braided cable, and adds a foldable built-in stand that holds your phone at any angle while it charges — one cable for the laptop on the desk and the phone beside it. $16.99
The E-Mark Chip
Cables rated above 60W are required by the USB spec to include an E-Mark chip, which tells the charger the cable can safely carry the higher current. A cable without one that claims 100W is not telling the truth — check for the E-Mark before you buy.

Pros
Every MacBook covered: 100W for Air, 240W for Pro, at phone-cable prices
E-Mark chips on the high-wattage cables, as the USB spec requires
Braided and silicone options, plus a stand version for desk setups
Cons
The 240W silicone cable is 1M only — desk setups that need reach should pick the 1.5M stand version or the 2M 100W braid
A 240W cable cannot speed up a slow charger — the brick has to deliver the wattage too
Verdict: Who should buy — MacBook Air owners: the PowerCord 100W Braided. MacBook Pro owners, especially 16-inch: the PowerCord 240W. Desk workers who charge a phone alongside: the 240W Braided + Stand.
