I bought a very cheap dock from a Goodwill store without a matching AC adapter. I could probably make a standard 12 volt security camera adapter for less, but this one works great and is very inexpensive. If it dies I'll probably try going to a CCTV shop or hooking up a cheap switching power supply, but so far I'm very happy. I've used it with both my Surface Pro 3 i7 and Pro 4 i5. , both with external graphics and a few USB devices, and works perfectly.
