Just wondering if it is safe to use other manufacturer's USB-C chargers to charge Apple laptops for example a MBA or MBP? I have some Lenovo USB-C chargers 45W and 65W and wondering if I could use those to charger Apple iPhone Pro 11 or 12, and Apple USB-C laptops for example a MBA that uses a 30W USB-C charger?

So far my M1 MacBook Air has mostly been charged with this charger ($23.30) since it arrived 2 days ago:


It has been charging at about 40 watts according to Coconut Battery app. I don't think there is any reason to worry about using 3rd party chargers as long as they are from a company you trust.

Great. I have some Lenovo USB-C Chargers that are for my Thinkpad and and X1 which are 65W and 45W. I also have a Lenovo USB-C Car Charger that is used to charge the X1 on the road and nice to know I can use that also for the M1 MBA or MBP that I will be purchasing.
Thanks!

In this same vein...
I work for a home furnishings company that includes USB ports for phone charging on desks and lights.
We're thinking about changing these built-in USB A ports to USB C for 2022.

My thinking is USB C powered by the same transformer - 1A 5V - seems rediculous.

For USB A, a slow built in charger is excusable, but for USB C, you might try to plug in a mac and have it not power at all. And for most people using these built in chargers, they're using existing apple USB A - lightning adapters that they've been using for years.

Thoughts?

I don't know that I would expect a built-in port on my light or desk will charge my Mac (though that would be nice), but I would expect any USB-C port on something I purchase in 2022 will be able to charge my iPad at full speed.
