80 Watt Zamp Solar Portable Charging System

I have had the chance to test and try out Zamp Solar’s 80 Watt portable charging system. Though not large enough to power a tiny house it is enough for a medium size trailer or motor-home.

I have a 1994 RoatTrek van conversion and we like to take it off grid at times and although it has a built in generator it is noisy and can have mechanical issues at times.

I have not been able to take take the solar system out for a real life trial, but wanted to share my experience with it by testing it at home.

My battery level was at 80% according to the meter on the solar panel. Connecting the system was simple. Using alligator clips I connected it to my battery and let the other end of the cord hang out through the opening. My battery is kind of difficult to get to so that took the most time.

The Zamp Solar panel comes in a very nice case. Simply unzip the case and remove the panel which is folded in half for storage. Unfold the panel and pull out the legs. Set the solar panel facing south or align with the sun to get the most light.

You need to set the solar charge controller to a wet cell battery which is what I have in the RoadTrek. Connect the solar panel cord to the cord coming from the batter and you are ready to start charging.

This 80 watt Portable Solar Charging kit provides 4.58 amps of charging power. It’s recommended to use this on 27-31 group 12v batteries, great for medium sized travel trailers.

Each kit comes with a 10 amp waterproof/weatherproof digital deluxe solar charge controller already mounted on an EZ-View bracket, 16 feet of wire with the new solar plug system with battery terminal clamps and a ballistic nylon carrying case.


Like I said earlier my battery was at 80% capacity when I started charging. It took approximately two hours to fully charge my battery. The charge controller stops charging once the battery is fully charged so it will not damage your battery.

I am looking forward to our summer trip when we spend eight days off the grid and I can use this silent solar charger to keep our electrical needs available without disturbing the peace of the redwoods.
