Working very good

I only use it to charge the battery of a car I don't drive much, and it works. It's compact, but if you need a more powerful charger, I'd recommend something better!.

I don’t put a lot of miles on my car during the winter. I bought this to try and make my car battery last a few years longer this time. It seems to do the trick. The car was cranking a little slow, the charger brought it back up to full charge Within a few hours. Car batteries are ridiculously expensive these days. If this little trickle charger extends the life of my battery just one year, it has paid for itself!

If a 12v batt is mostly dead it won't charge it. It think the batt is a 6 volt and says its full. When it is charging correctly it gets extremely hot. It is supposed to charge at 2 amps but rarely goes over 1.5.

Perfect little battery trickle charger. Hook up, plug in and your set. Always make sure your battery cable connections are clean or you are wasting your time.

This little gadget works well but it's plastic and if it's dropped or abused in some way I'm wondering if it would survive. However for the money it's worth it.
