That Charles 20 amp has basically most of the features you'd be looking for. I like the Xantrex products. I'm not a huge fan of either Guest or ProMariner. I'd prefer a slightly higher amps than 20. Technically, you would be limited to the amps of the shore power circuit. I have a Xantrex 40 amp (3 bank). About my only criticism would be the cooling fan, which is a little on the loud side. Since it's mounted on the bulkhead that seperates the engine compartment from the mid cabin berth, I can hear it sometimes as I'm falling asleep.
