There is more than just the power cord that is "light duty" inside a power strip.
GIven your application, I'd run a 12 AWG cord into a "four square" surface mount outlet box. If you are up to it, you can just screw the box to where ever and install two duplex wall style outlets with a metal cover plate. The cord can be run into the box (cut of the socket on the end) through a proper cord-to-box coupler.
This will give you four outlets at a cost that will probably be cheaper than any other method.
