Do you really have a 20-amp dedicated circuit? There are three things that rate the circuit at 20 amps: a 20-amp circuit breaker, a wire that handles 20-amps (#12 or #10) and a 20-amp receptacle.
A 20-amp receptacle (Nema 5-20) can accept both a 20-amp and 15-amp plug. A 15-amp receptacle (nema 5-15) can only accept a 15-amp plug. The 5-15 is the most common receptacles installed in houses. This limits your circuit to 15-amps and is the reason why the Panamax unit is rated at 15 amps (because it has a 15-amp power cord that only fits in 15-amp receptacles).
The difference in the receptacles is a 5-15 has the hot and neutral parallel to each other because the plug blades are parallel. The 5-20 has a "cross" in the neutral because the 20 amp plug has the hot and neutral perpendicular and the "cross’’ enables both the 15 and 20 amp plugs to be used.
If you buy a 20-amp power strip it will have a 20-amp cord and will not fit in a conventional 15-amp receptacle. You will have to replace it with a 5-20 receptacle and the electrician won't do it if the other two conditions are not met.
