127W Charger for Microsoft Surface Book 3 2 1, Surface Laptop 6 5 Go2 Studio Go 4 3 2 1, Surface Pro 10 9 8 7+ X 7 6 5 4 3, Surface Go 3 2 1, 11FT Cord&Carry Bag

It works flawlessly for me on my book 3. The cord length is great. Unfortunately its still a pretty big brick as designed by Microsoft, so portability is not great. It is possible to get a smaller (and lower power) portable charger and use a usb C cable, but you're going to be hard pressed to find anything that will charge a surface faster than this. Great product

I use my 15" Surface Book 3 a lot, and when I do it's usually running hard (simultaneous games/video/music/web).This charger keeps up with the heavy use and charges the batteries at the same time. I love the extra-long cable/charger and will never be satisfied with the stock 6-ft one. The high-power USB charging port is a big plus as well.I would recommend this to anyone who travels with their 15" Surface Book 3 and flogs it like I do.

Stopped working in less than 3 months. Useless product.

Worked perfectly sooo far

Aside from the extra power, this power supply has an extra long cord so you aren't tugging the brick all the time.

I am very happy with this charger. The cable is extremely long and I have had no issues with it since purchase.

I had to get a new charger because my dog chewed the low voltage cord on the original charger. For both the original and this replacement, the 120 Volt power cord detaches, but the low voltage cord does not, so I had to buy a whole new unit instead of just a cord. I wish they made the low voltage cord detachable too. A cord would be MUCH less expensive than a whole new unit.

This is a great, super beefy charger that feels more solid and has a longer cord than the Microsoft one that came with my Surface 4. It's an upgrade in every way from the stock one.If you have a Surface, you know how flimsy the little magnetic connector is. This one is beefed up as well, and less prone to breaking in my opinion. It still only has one USB output, which is unfortunate. It would have been nice to have a USB-C and USB-A out at the very least, since this has so much more power output available.This also comes with a nice cloth carrying case, which is great to carry this around in a bag, instead of having the brick lose in your pack and possibly damaging the connector.The only drawback is that this is slightly larger than the original on... not a lot larger, but enough to be noticeable. If space is at a premium already, then this might be too big to fit in your case. It's not a huge deal though.Makes for a good replacement to the stock one!
