So far its working great. I have used an older version of this solar charger in my truck for years. It keeps the battery topped off because I don't drive the truck very often

Works perfectly. Got an old car that seldom gets driven. Stuck this to the inside of the windshield, plugged it in the cigarette lighter, cranks wide open after sitting two months through freezing temps.

Like them and they are working. Too bad they weren't made in the USA

These type of 12v battery chargers are pretty similar. They utilize a trickle charge (under 2 watts) to keep a battery charged when not in use. They will not revitalize an old battery, and a failing battery will not renew itself. They are best on a healthy battery and work to increase its useful life. They are particularly useful on smaller 12v batteries used in motorcycles, atv, lawn equipment and the like, but work on any 12v battery. What stands out about this unit over similar ones is the customer service. I had a unit fail after 8 months of use. I contacted the company via their email address (found in their manual) and had a response the same day. A new unit was shipped and received within days. A lengthy 12-month warranty period backed with immediate response and care. That is exceptional service.

I needed something portable so a solar tricker is perfect as I have no outlet to plug a device in when I park at my apartment. It is perfect for my needs. Thank you. And you just plug it into the cigarette lighter. No installation.

It works just like the supplier said it keeps battery from completely dying

Positive output from panel is the MALE pin, NOT the FEMALE as the 1.8 watt panels are. The adapters were configured for each panel properly, however swapping adapters will cause a polarity mix-up. Well, shut my mouth!
