That means that, for now, you can’t charge a 2021 16-inch MacBook Pro at full power into one of the USB-C ports. Apple’s using some proprietary cable to MagSafe. There are yet to be a C-to-C cable rated at EPR levels though. Apple was instrumental at proposing the 28V, 36V, and 48V new voltages levels to USB’s working groups, so it would make sense that they were planning on releasing the first implementation. I expect that it is a USB PD 3.1 EPR charger (the world’s first), using the first new voltage level, 28V at 5A. The problem is that the standard is so new, there isn’t yet a USB-C to USB-C EPR-rated cable available, as Benson Leung explained on Reddit (via CNET). Apple’s implementation is limited to 28v. 16-inch MacBook Pro charger limitationĪpple’s new 16-inch MacBook Pro charger uses the new USB PD 3.1 EPR standard, and is – as far as I can see – the very first charger on the market to do so. This delivers up to 48V at 5A, supporting anything up to 240W. This new standard is known as USB PD 3.1 Extended Power Range (EPR). A new standard was developed to support power delivery of up to 240W, and Apple was instrumental in driving this. That was fine at the time, but with higher-powered laptops on the way, more power was needed. This allowed for power to be delivered via USB-C cables at up to 100W. When the USB-C standards were developed, there was a specific standard for charging, known as USB-C Power Delivery (PD). Update: The newness of the standard also means the USB-C ports aren’t compatible with it. The bad news is that the technology is so new that there isn’t yet a compatible USB-C cable. The good news is that it’s the first one on the market to offer a new high-power charging standard that enables USB chargers to exceed 100W for the first time. If you need a longer cable, make sure you get one that’s capable of supporting that speed.There’s good news and bad news about the new 16-inch MacBook Pro charger. There’s a Type-C cable included that’s 3.3 feet long and capable of charging up to 100W.

The USB-C port can deliver 87W via a supported cable and up to 24W total between four USB-A ports. Additionally, it’s important to make sure the cable you buy also supports the wattage the power brick can provide.įor most MacBooks, this 111W charger from Nekteck will work perfectly. If you think you’ll be using your laptop on the couch and the closest plug is across the room, make sure the cable that comes with the charger is long enough to reach. For the ones that do, they might not be long enough. Cable Length: Many of the chargers on this list don’t include a cable.If extra ports are important to you, make sure you choose a charger that has a few extra charging ports built-in. But many of these MacBook charger replacements are also capable of charging other devices, like your smartphone. Available Ports: If you’re looking for a brick to charge your MacBook and only your MacBook, that’s totally fine.For example, a power brick may say it’s capable of outputting 100W, but this could be a combined wattage of one USB-C port that outputs 80W and one USB-A port that outputs 20W. Wattage: While you’ll need to make sure the wattage supported by the power brick is powerful enough for your specific MacBook, you’ll also need to note how the power is distributed if there are multiple ports.For example, the latest MacBook Pro needs a 100W charger to power it, whereas the latest MacBook Air only needs a 30W charger.
