The new 80 watt USA portable is perfect for single battery RV with an LP (propane) two way fridge, which runs on 120v or LP. Most people don't realize that even when the fridge is on LP it still uses about 1 amp of 12v to monitor the system, light the pilot etc. So that leaves you about 4 amps per hour of charging power to the battery. The water heater also uses 12v while on LP, add the water pump a few times, LED lights and charging of tablets or cell phones. The 80 watt will still handle it.

If you have an inverter or two batteries, then I would consider stepping up to the 120 watt portable at a little over 7 amps per hour being produced.

Every campers needs and power consumption's are a little different, so just because some brochure says this one is for a single battery, and this one is best for 4 batteries, don't believe it for a second.
