Replaced my onco charges with a pair of these after 3 fail oncos in the last 2 years. So far I am very pleased with the performance and the quality construction of these chargers. Very good quality. The lower price is just a bonus in my opinion.

So far so good. Have only used it once so far on my boat batteries. It's done what I needed it to do. The true test will be repairing and charging differe t batteries.

I really love this battery charger. This is actually the second one that I’ve ordered. We use it in our boat because we’ve been stuck out on the water before and the battery went dead. It’s definitely a lifesaver and it’s lightweight and it’s very easy to use in the last a while.

Would have been a 5 star but the terminals terminated on the battery wires were too small for the battery studs. I had to cut them off and reterminate with larger ones.
