In my opinion, using a 60-ish Watts USB Power Delivery charger with the 14-in M1 Pro MacBook Pro should be reasonably safe. If you decide to run your MacBook Pro using a much smaller charger, you are heading into uncharted territory, and you will have to decide for yourself whether the risk of damage to your multi-thousand dollar computer is worth the modest savings on power adapter and weight.

But while we generally agree that such a smaller charger should not be used to RUN your MacBook Pro, it can be used for emergencies to re-charge when your Mac is nominally off. It will charge exactly the same way under normal circumstances.Īpple never recommends the use of a smaller-than-specified USB Power delivery charger.
It is fair to say generally that use of a larger-than-specified USB Power Delivery charger has no impact except that it weighs more, and may run slightly cooler. That said, knowledgeable Readers here have internalized and synthesized that information to make modest additional suggestions based on that information. We do not have access to any special insider information beyond what appears in Apple articles and general background knowledge. The USB-C has to be the least reliable, least stable and least durable of any USB version every created (with perhaps the exception of Micro USB!) and to have it as the sole connection on a Laptop is ridiculous, which luckily Apple finally acknowledged and undertook are very rare reversal of their usual "bulldoze through with changes regardless of how much it annoys people" strategy of recent years!!! (yes we do still want to replace batteries and add more RAM on a MacBook and have Kensington slot and we do want an audio jack on our iPhone, but we don't care about reducing the thickness of our iPhone of MacBook by 1.45mm at the cost of reducing battery life, and yes a MicroSD slot on an iPhone would be great even if it messed with your hypersensitive minimalistic design aesthetics.) I am very keen to get rid of this USB-C model MacBook Pro and replace it with a Magsafe 3 model, but have invested in quite a few USB-C chargers and battery packs etc which are all between 45W and 60W), so keen to know if the 14" 10-core model will work in any way with them and/or if the 14" 8-core will be more backward compatible.
I am also aware of other scenarios where a MacBook may provided power, but not charge the battery (as in you can use the MacBook and the battery won't deplete), or where the MacBook battery will get charged but only if the computer is shut down or put into sleep mode - when being connected to a USB-C power source that is less that is stated in offical apple specs. However I have 45W USB-C wall chargers and 45W 12v car charger sources which provide power and charging while I am still using the MacBook. I am currently using a MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports) - of which the offical specifications claim requires a " 61W USB-C Power Adapter". Almost in every instance the charger that was supplied for a MacBook would work in some for or another with the model above it. This was the case for the Magsafe 1/2, the circular connector before them as well as for the USB-C models. In my experience for that last 10+ years of Apple MacBook laptops pretty much every iteration has had some cross compatibility between power supply wattage and computer charging requirements, regardless of what Apple's offical specifications claim. Is the section you included that is in quotes from an offical apple source?
