Mag-Safe to USB C Adapter, USB C to Mag-Safe 1 & 2 Charging Connector Adapter Compatible for iPhone 15, M1/M2 MacBook, MacBook Air, MacBook Pro 13'', iPad with USB Type-C

This little device brings mighty power to my MacBook Pro M1 2020 from my 27" Thunderbolt Display. Since the power cable comes directly from the back of the monitor, this adapter eliminates the tangle of extra cables. Since this version of the MBP didn't have MagSafe charging, it has USB-C/TB, this device works wonders! There was a couple of times that it was not working very effectively, but I flipped the MagSafe back and forth, that maybe the prongs weren't as responsive. But after some tinkering, it wound up working great.

The "Mag-Safe to USB C Adapter 3-in-1" version that is being sold here only provides 30 watts to my 15" 2018 MacBook from my 27" Thunderbolt Display (which provides up to 85 watts), despite the adapter's description claiming to provide 45/60/85 watts. 30 watts isn't enough to prevent the battery from draining while using it on a laptop that normally has an 87 watt charger. I would have been fine with it providing 45 which wouldn't charge the laptop during use but would maintain the battery, or 65 watts which would charge it slowly, but only 30 is unacceptable. Even at 30 watts it gets quite warm, although not hot. I'm returning this.

I inherited a really high quality Apple external monitor that has the functionality to charge your laptop, but the charger was a magsafe1 with a magsafe2 dongle and a computer with a usb-c charging port. I got the version with only the magsafe input and USB c output and it works with both versions of the magsafe that I have and with my MacBook pro. Great solution to keep older technology that is otherwise in perfect condition out of the garbage and be able to keep using it!

I was able to resuscitate an old Mac power supply.

Better description/ detail needed for this item. It does not perform the function (conversion/ adaptation) advertised.

The product does what I need it to do. I had a Cinema Display sitting in the closest for a while and I started working from home more often. I decided to break it out and use it with my Dell Lattitude 5431 (work issued). The first thing I needed to do is find a dongle to get the display output. For those wondering, the USB-C that can be used for display output with a Dell dock does not work with the Cinema Display, at least one I bought didn't. A HDMI to minidisplay one worked though.As for this product. Well, it's a couple of small things. At first I didn't think it was working at all. I then discovered that the MagSafe was wasn't staying connected. I then discovered that the dongle wants it connected only one way. So while MagSafe is omni-directional this dongle is not. So, if you're having trouble with it staying connected flip the MagSafe connector and it should work a lot better. Next, the power output in the listing has me all confused but regardless of that the power output with my Dell Lattitude is quite terrible. When I use a 65w USB-C laptop charger I was getting "57 minutes complete until charge complete". With the dongle it was 2 hours and 57 minutes, meaning this thing is outputting 20w-25w. For the type of tasks I'm doing it's fine but if you expect your processor to be running full tilt for any lenght of time this dongle will not keep up. Last, and this one isn't the least problematic but I thought should be mentioned in the listing, the ports on the dongle (Type C PD and the the old USB-A) are power ONLY. They do not handle data. So, if you wante dto charge your smart phone and access the content only it, you're out of luckSo for me, it'll get the job done but the price for this does not justify the quality and its shortcomings.

Why did you pick this product vs others?:I wanted to keep using exiting Magsafe 2 power cords with a newer Macbook, and add a USB-A port. Usb ports:USB-A port does not work with any device that I've tried: DVD player, mouse, or tablet. Functionality:Magsafe 2 adapter works most of the time. If someone trips over the cord, hopefully it will release.

the product works well enough,i'm happy that it did what i needed to do.but the usb-c and usb-a don't seem to work.
