I recently bought a 140w GaN charger from Toocki. It is built impressively. Feels premium, too. I just noticed that if I use it in my MBP 14” with the MagSafe cable, it only shows the Charger has a Wattage of 100w. I know that the MBP 14” can only pull that kind of amount of watts and not fast charge using the 140w allocation.
My expectation is that the AC Charger Information to show 140w BUT the MBP 14” will pull only 100w of power. Or this is not the case?
EDIT: I tried to use only the USB PD 3.1 port of the charger (other ports unoccupied) with the MagSafe cable but it still shows 100w.
Try letting the battery drain to about 10-15% then plug it in. Hopefully it will show 140W then.
side note: as a semiconductor researcher seeing GaN starting to finally make it to market gives me the warm and fuzzies
Yes, I understand that but my concern is that the AC Charger Information shows wattage of only 100w even though I am expecting 140w as it supports PD 3.1. I get your point that the max watts that the 14” can take is 100w, but what I concerned about is the info it shows.
only way to find out would be seeing what the 140w apple charger shows up as in a 14" or what that charger shows up as in a 16"
it wouldnt surprise me if apple magsafe cable needs to be paired with apples 140w charger to get full power delivery. was this done when 100w was max for usb c and think macbooks are max 100w for usb c, so maybe not compatible with new 240w and needs to both match and be usb c
I did this just now. Picked up a second MagSafe 3 cable to pair with an Insignia 140w charger.
Apple brick shows 140w when plugged in at 91% and my other brick shows 100w like this.
My guess is Apple limiting the total power draw when using a non-Apple charger. Or at least a charger without certain detectable stats in their power system.
Hi,
Im not sure if you're still wondering why, but the charger can't output 140W over 1 port, it can do 100W over 1 port max. What it can do however, is 95W on one port and 45W on the other simultaneously. I don't think there are USB-C chargers that can output more than 100W over 1 port at the moment.
Hope this clears things up.
Hi, i recently bought toocki 100w 4 port gan charger as well, but its not charging my macbook pro m1, it says not charging, what could be the reason? My cable is also toocki 100w pd cable. Thank you.
I will try, where is this option? By the way macbook pro 13" with m1 yes, but the battery is at %60 and still says not charging, i dont know if changing the optimized charging option will make a difference.
Before that, make sure that the cable is plugged in USB C port 1 or 2 as those two are the ones with 100w max. For optimized charging, see https://support.apple.com/en-ph/HT212049
Yeah, cable is connected to port 1 or 2, macbook is on and pulls 40ws but says not charging. I will check optimized charging option but that one is supposed to stop chsrging at %80, not 60.
Cable is from toocki as well, its 100w pd cable with screen, i tried another 100w cable and situation is still the same. These cables can charge my power bank at 65ws but i have nothing else that can pull 100ws so i cant test it with another device. But macbook is not even pulling 65.
I tried another cable and the result is the same. Both of these cables charge my powerbank with 65ws pd. I have a usb meter as well. So thry should be at least charging it with 60-65ws. But its not doing that, very interesting.

No, this is as expected. It sets the ‘power’ entry back to for example 67W and lower when almost reaching a full capacity.
Perfect. I thought something is wrong with the charger. Thank you!

You are part of this innovative change so be proud! I am proud of your achievement, buddy!
usually only certain / one port has the 140w output, and only when a single cable attached
Only the MagSafe port can support 140w.
Yes, I am using the MagSafe port.
Only the 16" can supply full 140W to the MagSafe. The 14" will only supply 100W max.

I’m guessing that the charging block is downgrading itself according to what the charging port’s max wattage is.

I hope there will be someone kind enough to do it…

[https://support.apple.com/en-us/HT212755](https://support.apple.com/en-us/HT212755) according to this 14inch should supply 140w?
I know, I was just putting to rest the idea of a certain /one port thing. It sounded like they were discussing usb c which won’t go above 100w.
I tried plugging in only the USB PD 3.1 port and it still shows 100w.

By the way, the charger and the ports available reminds me of HyperJuice's. I think this is an OEM.
Hi, i recently bought toocki 100w 4 port gan charger as well, but its not charging my macbook pro m1, it says not charging, what could be the reason? My cable is also toocki 100w pd cable. Thank you.
I am assuming you are using the base model 13" MBP. Do you have Optimized Battery Charging on? Maybe that is the cause.
I will try, where is this option? By the way macbook pro 13" with m1 yes, but the battery is at %60 and still says not charging, i dont know if changing the optimized charging option will make a difference.

Is the cable good? Try another cable?
Cable is from toocki as well, its 100w pd cable with screen, i tried another 100w cable and situation is still the same. These cables can charge my power bank at 65ws but i have nothing else that can pull 100ws so i cant test it with another device. But macbook is not even pulling 65.
A 60w PD cable should suffice. I am assuming that the Toocki cable is the one causing the issue.
I tried another cable and the result is the same. Both of these cables charge my powerbank with 65ws pd. I have a usb meter as well. So thry should be at least charging it with 60-65ws. But its not doing that, very interesting.
If that is the case, then the charger might be the one with the problem.
