[Upgraded Version] Surface Pro Charger 65W for Surface Pro 3/4/5/6/7/8/9/X Power Supply Adapter, Compatible for Both Microsoft Surface Book Laptop/Tablet，Works with 65W&44W&36W&24W (10 Ft Cord)

I had another charger for my Surface Pro 4 that worked fine but I noticed that while it was plugged in and charging (under load) it would emit all sorts of RFI while using Digital modes on Ham Radio. I could mitigate it by removing the plug from the Surface but then, I am on battery and thus limited time. THIS charger, however has no change in noise floor when just plugged in or charging the surface. PERFECT! Not only that but now I have a spare USB port to utilize for accessories. The plug pops into place and fits as it should. Charge rates meet that of the original as well.This is a very high quality non-Microsoft charger....meaning they actually manufactured it with chokes and proper components.

This non Microsoft surface charger had me a bit nervous as I just was unsure if it would fit & function as well as the Microsoft official charger. However, especially given the price paid, I could not be happier... It functions at least as well as the charger which came with my Surface Book in terms of charging capabilities, but it actually fits the Surface Book connect port better than the Microsoft version when using the display adapter, dp1.2 port at the same time to connect to an external monitor- in fact, I'd bought the real, Microsoft Surface Dock/charger to use a while ago for docking my Surface Book given it had 2 Display Port 1.2 Adapter ports + HDMI & 4x USB 3.0 jacks, however, the connection doesn't hold as well as this slim version, so I kept losing my display, back up drive, etc because it wouldn't remain connected consistently or nearly as well as this 3rd party charger does. Also, when using the display port w this charger directly on my Surface Book rather than using 1 of the 2 on the official dock instead, because this is a slim design & only is carrying power, it fits/plugs in much easier than the Microsoft Surface Dock I have, which won't fit the surface connect jack well when the display port cable is plugged into my Surface Book directly rather than through the dock... While it's just a basic charger, I've found it's a better option when docking my Surface over the Microsoft Surface Dock due to fit, function, better/reliable connection & more compact connect plug. The cable length is similar to the OEM charger cable & I've had zero issues as far as complications from using a 3rd party product. Instead of using the official Surface Dock, because the connection wasn't holding consistently, I'm now using this charger for power, a DP1.2 connection port on my PC for the external monitor & then a $15 USB 3.0 extender to connect added/backup drives, wireless keyboard/mouse, etc & it's much more reliable this way than attempting to use my Microsoft Surface Dock. So overall I was hesitant initially about getting this as was worried about using 3rd party equipment, but I'm actually happier using this charger when I dock my Surface Book than I had been w the Microsoft Surface Dock I'd bought previously. It's a great product, works well & solved the connection issues I was having using the display port on my PC because even the OEM charger (not docking charger/station, but rather original charger out of the box) wouldn't fit into the connect port with the dp1.2 port in use plugged directly into my computer. So couldn't be happier & will probably buy another to replace the OEM charger soon, which is beginning to have connection issues as well. Good quality, good value, great job for what it's made for- highly recommended for sure!

It's too early for me to really know the reliability of this charger but my initial impressions are very good. It starts charging the moment I connect it, it feels well-built, and they even included a little velcro cable tie. It also stays cool during operation. The price compared to the OEM charger is a no-brainer.The OEM charger that came with my Surface laptop has always blinked a few times when I would plug it in before it began charging. This was from day one. I assumed this was normal because other than that, it worked fine and would keep the laptop charged. However, recently, I started experiencing issues where it would stop charging and I would have un/replug multiple times to get the OEM charger working again.This replacement charger has not blinked a single time - it starts charging instantly.So far this is looking like a great replacement for the OEM charger. I'll update the review in the future if necessary.

Does the job but breaks easily

We have had it for a year now and it works great! Despite being used very day it still looks brand new. I am very pleased with this purchase.

This Surface charger is a great replacement! It's powerful enough to quickly charge my Surface Pro and the cord is plenty long. I like that it's compatible with older Surface models too, just in case I need to charge another device. It feels well-made and the price is very reasonable.

Doesn't work at all. Beware! I've followed all of the troubleshooting steps. The steps are well written and logical. My home outlet works, my original power supply works, all of the connectors are snug, no damage, no frayed cable, nothing. I've had problems with this charger from the beginning but I rarely needed it so I didn't bother asking to have it replaced or writing a review. But now it's clearly dead for no apparent reason.
