I suspect that these "power supplies" are actually UPSs and the 13amp is their output rating.

If this is the case, they need a 20amp plug because they can charge their batteries AND provide 13amps to a load at

the same time, this puts the input over 15amps!

Hence, the 20amp plug to achieve UL listing.

Correct outlets on proper circuits should be installed.

Alternatively, get smaller units that will run on a 15a source.

Shame on those who ASSUME that the plug is wrong and suggest changing or modifying it.

No, they aren't UPS's, they keep voltage on the CATV lines, which is needed. And the plate on it says 10Ampere input, 9Ampere output load, surge load 20Amperes. Believe me, I don't support the "Prong Twisting" either.
