Works well to keep trailer battery charged.
I bought this to keep my trailer battery charged during winter storage. For that it is great. I really wanted an intelligent charger. The improvement in battery life over a simple trickle charger should easily pay for itself in a couple of years. The mounts could be better. The suction cups are useless. I made some standoffs and mounted it on the propane box which sits on the tongue so that is not under the trailer cover. I checked the set up a couple of months into the winter and it was working great. If things change by spring, I'll update this review.

Great little car trickle charger
I have a tractor which I store in a shed without power, and it can lose battery power over the winter.This little charger keeps it topped up and is plug and play. I tested it on my convertible since it already has a 12V adapter connected (pics attached).I literally just put the suckers on, connected it to the wind sill and connected it to the battery. The light started blinking red which means charging. Hopefully it will be fully charged by the end of the day.Excellent little plug and play product.

Lots of useful cables
Got to keep my car battery charged because I drive less this year. Panel comes with a lot of cables to help install in various setups. Like the LED on the panel to tell if it’s working. Best part is it seems to work when inside my car

Works great!!
Works great keeps12v Automotive battery topped up and works in less than ideal lighting situations. A lot cheaper than replacing brand new batteries that run down due to lack of vehicle use due to disability and pandemic. Will purchase again!!

Very dependable easy to use
I used for backup charging house generator. It does the job I wanted very well. Would have liked some alternative methods for mounting on non slick surfaces but definitely not a deal breaker.
