5-6 years still going strong

I have been using the EP1250 for lite duty for over 5 years. Still running a variable ~40w load nealry 15 hours and shutting down safely as expected. Will buy again.

Waiting to use

I ordered a battery and charger. It arrived exactly when expected, but, I was out of state halfway across the country and couldn’t inspect it. 8 days later I arrived home, opened the package, inspected, read the instructions, and charged the battery in just a few hours. Now I am going to expand it with two more and find something to use it with.

Unfortunately didn’t work for my need, not enough CCA to start the engine

Smaller than it appears in the photo.

It's hard to actually rate the product right now. I really won't know about it's capabilities until I have used it for awhile. Check back with me in a year.
