Charge 2021 16” mbp m1p with 95W 2016 MBP

[GustavPicora]

Hello all.

I just got my 2021 MBP with M1 Pro and i was wondering if i could use the 95w usb-c power adapter, from my (now old) 2016 15”mbp, that i have in the office so i wont have to carry the adapter up and down. Most of the energy consuming task i do is at home when I’m editing raw photos. At the office i do iOS development .
Any thoughts? Risks?, no no solution?
Thanks in advance.

That would work fine, just a slight bit slower to charge. I use my Pro Display XDR via TB3/USB-C to charge, and have had no issues.

M1 Pro should be fine with 95w charger. CPU itself doesn't drain 50w of power AFAIK. So it should be fine

Amazing, thanks guys.

In fact, my 65W third-party charger can also charge 16", but I still use 140W to charge.

I actually bought a new Apple 67-watt USB-C charger and another MagSafe cable as my secondary charger for my 16" M1Pro. Works flawlessly for me; I have no need for fast charging though.

The charger with the 2016 15” MBP is 87W. Anyway, should still work fine to charge it.

Tagging onto this... other than slow charging time, are there any issues or risks with using lower-wattage USB-C chargers? (Just for charging, not for using while charging.) I also have a new M1 16" MBP, and the 140W charger it came with of course, but we have a mix of MBA chargers, an Anker 60W, etc.

The awesome battery life minimizes this concern somewhat -- for my previous 2015 15" MBP, I had chargers in several rooms and a backpack .

I am curious about this too. I just got the new 16 inch MBP. I absolutely love it coming from a 2016 15 inch. I believe it is an 87 W adapter. I'd like to still use this one. We also got a new 14 inch that came with the 67 W. Should this be interchangeable too?

Additionally, I'm looking to finally get a true USB-C or Thunderbolt monitor. Tired of using the adapters to go from the DVI connection to USB-C/Thunderbolt. Will a new monitor with a true USB-C/Thunderbolt direct connection to the MacBook provide power to the 16 inch and 14 inch MacBook Pro? If so, then do I even need to connect the MagSafe power or Thunderbolt 4 power cord to the MacBook itself? Also, any good monitor recommendations? I'd then like to daisy chan two of the same monitors so I can just have onle plug into the MacBook Pro to deliver power and to drive the graphics to the screen. Maybe this is a pipe dream. Hoping this is possible?

I have at home the MBP connected to a Benq SW271, it has usb-c and over it it sends only 60W of power. It was enough to charge my old 15'' MBP, but the 16'' wont charge. I think there is a new Benq or other brands with more power output over usb-c. Or maybe another brand. ?

There is no risk in my experience - I use a 30W MacBook Air charger for my 14" M1 Max, most of the time running the Mac while charging. Even while under considerable CPU load, max memory usage (64GB) and driving an external monitor the Mac still charges slowly. The battery health is still excellent after 21 cycles and 3 months of use - hard to put complete cycles with this sort of battery life.

I never used the 140w, I use a Nekteck 100w charger

I'm seeing a curious issue with a third party 100w charger. Its branded Andersson and also sold under other names. It has two USB-C and two A ports. Works fine. Unless you run the Mac at full tilt.

During intensive export/render sessions in Premiere, the Pro 1 Max will peak for short intervals at up to about 120w power draw (according to istat). That Andersson charger will basically stop working, and I have to replug it to the wall socket to get it going again. Some kind of internal safety/fuse going off I guess, even if its rated for 100w over USB-C and shows up in hardware info under "Power" as 100w. Charger doesn't get unusually hot.

Of course the Mac doesn't hiccup at all.

Yes, yes. Don't use 3rd party stuff yadayada. The convenience factor of the multiple ports is unquestionable though.
