PulseTechSolarPulse SP-7 Solar Battery Charger Maintainer, Blue, 7 Watt

Great charger, works perfect. I only wish I could find an extension for the cord.

This keeps my battery topped off on my Travel Trailer during storage.. Works great.. the other review said it was bent,, I think its made that way. Mine is a little concave, but very strong.. I just zip tie it to the trailer during storage, and take it off when i use it..you just unplug it.. the little red light is kinda hard to see. but it works fine in about 6 hours of sunlight.

Used to charge my battery on my trailer seems to be working fine

The ease and quality of this battery tender is awesome! Just enough charging to keep my marine battery on my tri toon topped off! Battery level keeps a constant 12 volts! Definitely would recommend!

Bought to keep a dump trailer battery topped off between uses. Don't use my dump trailer all too often and so far I haven't needed to use the rapid charger between this and the charging while hooked to tow vehicle. Bought another smaller one for my horse trailer for the electric jack battery.

This thing does not charge your battery’s all it does it drain battery then stuck with no power period. I’ve called company who makes it and they wanted know part in a return or send it in to get fixed I’m very unhappy was a waste of money

I had it in indirect sunlight for the first 6 months, didn't work so well. I moved it to another area by my motorhome in direct sunlight and it had my batteries up to 14.7 volts. There doesn't seem to be a happy medium, and I fear it is boiling my batteries dry. Now I plug it in for a week and unplug it for a week. Doesn't help with boiling the batteries dry, but there isn't much else I can think of while the motorhome is in storage for the snow season. Unable to contact customer support for this issue, either.

Used 4 rare earth magnets to mount it which makes it movable to position in the sun. When not using the trailer, I put it on the top rail in the sun.
