- “Can I use the Surface RT power supply on a Surface Pro?”
SURFACE RT POWER SUPPLY ON SURFACE PRO
The answer was briefly addressed by the Surface team during their recent AMA on Reddit. YES, you can although the charge will be much slower.
From my own observation, this makes complete sense: They operate at the same voltage but charging will be much slower because the amperage of the RT power supply is almost half of what the Pro power supply is. This matters to many primarily because of the disparity between the cost of these two accessories.
- Surface RT has a 24W Power Supply (12V at 2A, $39.99 MSRP) – See photo above
- Surface Pro is 44W Power Supply (12V at 3.6A, $79.00 MSRP) – See photo below
SURFACE PRO POWER SUPPLY ON SURFACE RT
Conversely, the Surface Pro Power Supply works on the Surface RT. While I haven’t seen any specific documentation on this topic on the Surface support web site, I’ve snapped that onto my unit and it charges just fine. Possibly even faster due to the higher amperage but I wouldn’t know since I’m not benchmarking the charge.
Ordering for either power supply is available at the Surface web site:
