Surface Book replacement charger from dock

[paparazzo79]

Hi guys.I got myself Surface Book 1 but instead of charger I got this (from pics).
May I use it to charge the Surface Book or I need original charger?
6 Amps seems to much.

6A is what it can supply, that doesnt mean the tablet will draw that much.
better to be over-rated than under.
btw, the original chargers are shit - so if you got something else it's a plus

6A @ 15V = 90W charger. I suppose you could even go down to 30-45W. My 14" laptop from work got a 60W PSU factory , USB-C charging. I plug into any PSU ranging from 30W to 120W no problem. You do get a notification from windows with a low rated power supply (like a 30W or 45W) but never the less it does charge. The only remaining question is: How fast do you want your battery to charge?
