Surface Pro adapter modification Answered

Hi guys, I have been experiencing problems with my Surface Pro adapters (both original and "OEM") where the adapter would power up the tablet but simply won't charge. I decided to probe the connector prongs and found out that the adapter simply outputted 12 volts (and supposedly 2 amps) through the pins. Since both adapters simply supplied 12v to the prongs, can I replace the adapter with a 12v 3a one while keeping the original cable?

I've done it myself a few times, so shouldn't be a problem.
I wonder about the power though.
None of my laptops has a power supply rated under 4 amp.
2 amp from a genuine charger isn't even enough for a modern cell phone anymore IMHO.
