I ordered another charger for my new 8500w generator, came back to the site and found that it was unplugged every time had to be needed well i can't remember throwing out the trash half the time in 70 years, i saw this one that doesn't charge. I run my generator every Saturday and find that it's shut down. After I started the generator and let it run for two minutes and then turned it off, the charger came back on. Exactly what I want. I say buy. Have you ever bought a lemon of anything before in your life? Well, what will happen with this charger will not work sooner or later.
