DENAQ - 12-Volt DQ-MS122586P Replacement AC Adapter for Microsoft Laptops - Black

Bought this Adapter for Microsoft Pro Surface and works great! The brand name was over $100 and this one was under $25 and it is fine.

It works to charge my surface. Nothing special about it. Length is plenty long enough. Only negative thing I can say about it though is that the adapter box gets very hot pretty quick, not sure what means for performance but just a warning for potential buyers.

At the end of the day, it doesn't hold a candle to an original Surface Pro charger. However, I'm replacing a charger for a Surface Pro 3 which probably will only last another year or two. Didn't make sense to me to shell out $70+ for the original MS charger when $20 gets you this one. Only criticism is that sometimes the adapter needs a couple of tries to get a power connection going but again, I don't really need it to be perfect. You might feel different.

The description says it works with Surface Book Models. I was surprised to see the size of "brick", it is much smaller than the one that came with the Surface Book. I also never found Watt Output, both online before purchase or on the device itself. When I connected it to my Surface Book, it didn't charge, and actually caused my surface book to think I was trying to disconnect the monitor. I will be returning this.

Charger worked for 6 months until it stopped charging. Would give it a 3 star review since that's pretty standard for an off-brand charger and how long of a warranty they give you, but when it stopped working it started producing smoke, sparks, and loud noises out from the body of the charger, and that seems like a pretty big hazard especially if the charger was left unattended.
