Sorry if this triggers anyone lol. I lost my magsafe 2 charger for my mbp retina 2013 but had a bunch of old magsafe 1 chargers laying around… i noticed even though the middle pin is smaller on the first gen magsafe, they are placed similarely across generations so I figured why not. As you can see my mpb is charging with the first gen cable ! I wouldn’t necessarily recommend it as I’m not sure of the effects it could jave on the battery, but mine is already fried anyway so 🤷🏼♂️. Didn’t see anyone else talking about it online so I decided to post here !
hi, i'm bringing this old topic back to life for a hyperspecific issue i can't just solve by getting a magsafe charger (which, i already have, i just want a proper use for my ugreen...)
i got an early 2015 macbook pro for christmas, and also a ugreen uno 100w which - i imagine is faster than the 60w charger that came with the macbook?? though the fast charging bit of it is only usb-c, and for me to use this on the macbook which was the original purpose... is to get a usb-c to magsafe 2 cable!!! except where the heck do you find ones that don't look super shady!!!
i specifically want a dark/black one though i will settle for one that is non matching to the silly bmo looking ugreen. if anyone reading knows where to find these pleaseee tell me, ive only found a couple amazon candidates and im not sure how compatibile they would be with the ugreen in the first place- wattage just confuses me in general. i will update if i find thank u for considering :>
You don't want to mix those two.
Why?
Because the USB-C port conforms to the USB 3.1 Power Delivery Specification whereas the Magsafe charger does not. Part of that specification includes the negotiation of delivered power. The Magsafe will not negotiate how much power is supplied. What it's looking for is the presence of the 1 wire charging circuit before it begins charging.
There may be adapters/converters on the market that will convert one interface to the other and vice versa, but (IMO) those cheap adapters are not worth the risk of sending the wrong voltage to your very expensive MacBook Pro.
Bottom line, use the genuine adapters built and designed for your MacBook Pro.
The ElecJet Anywatt One fills this need, for the purpose of powering a USB-C device from a MagSafe power supply.
From the product page:
Anywatt built-in self-developed LDR6032 smart chip supports the latest USB C Power Delivery & PPS protocol, Automatically recognize the end device needed power and adapt the voltage and current to best suit the end device charging purpose, range from 5V@3A 9V@3A 12V@3A 15V@3A [email protected] and PPS 3-12V@3A MAX.
It is not licensed by Apple. That said, I own one and have been using it without incident to connect my 2016 MacBook Pro (87W) to my Thunderbolt Display; it can't provide the full 87W, so the battery charges somewhat more slowly than it would if I had the big charger with me, but it's been fully adequate in practice.
