Does its job

28 days ago
Hooked it up to a car battery to maintain its charge. It took a while but did charge the battery. It seems a bit flimsy, so don’t know how long it will hold up. But, so far it does what it is supposed to.

Compact charger

29 days ago
Wow this is a great easy to use portable charger. We used this to get a friends ca started after the battery died due to non usage and within a short time the car was up and running again. Price point is good too making it affordable for most. This may be small but it’s sturdy and durable.

Great compact product life saver

a month ago
This 2 Amp charger is perfect for anyone who isn’t a “car person” but wants to avoid a dead battery. The smart charging technology is great because it automatically switches from charging to float mode monitoring. It’s compact enough to stay out of the way in the garage, and the mounting hooks are a nice touch for organization. Highly recommend for motorcycles or cars that sit for a while.

Great maintainer to have on hand!

a month ago
My husband has used this maintainer on his truck and lawn equipment and says it’s exactly what he’s needed. He doesn’t drive his truck daily, so this keeps the battery ready to go without any issues. He also used it on our John Deere mower and it brought the battery up to full charge quicker than he expected for a 2-amp unit. It’s simple to use- just hook it up and let it do its thing. I also like that it charges with little noise. Overall it’s a great maintainer for anyone with vehicles or equipment that may sit for periods of time. It works great!
