Rated 5.0 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by Good Product I needed a Generator for my outpatient surgery center which houses two operating rooms and decided to go with this Geneforce. It works great and gives me great peace of mind. August 27, 2012
Rated 5.0 out of 5.0 Amazing!!!! Probably the best money I have spent in a while. My fiance and I live in Los Angeles, CA. We love to go dirt bike riding, quad riding, and basically anything with wheels. We like to spend weekends camping at Glamis in the desert. While staying out in the desert we realized we needed a generator so we can stay long weekends. Geneforce was made for us!! We power everything from can openers and lights to speakers and sound systems. We also charge our KLX140 bike with it. Probably my favorite part about this product is that it can recharge itself with a solar panel! We tried it at home a few days before the trip and it lasted days! So besides the desert having hours of pounding sun it worked back home where it wasn't so bright. It didn't run out of energy and was extremely quiet, usually thats hard to find with generators. We were also able to rig it up to our huge trailer. One of our friends had a mobile home they brought out there and we were able to provide them with energy too. Since we used the solar panels to recharge itself we didn't mind. The only thing I had a hard time with was that it had wheels on the bottom and we were in the desert sand. Not helpful for us but not many people would use it the sand I guess, perhaps. My fiance just picked it up and moved it over, problem solved. January 15, 2009
