It's a little confusing as to what is going on but if you are using it to start your vehicle it works well. That's my feedback.

I have an older vehicle with a power drain, this has been a big help, keeping the dual battery's topped up while I try to figure out what's drawing my power down.

I bought this as a replacement for an older charger that just died.Used it a few times to revitalize a battery which hadn't been used for about a year and it worked well.The other day I used the "jump start" feature and it worked! Saved me a major hassle.Really happy with this. Also, I had to talk to their tech support, and they were very friendly.UPDATE: Just used it a 2nd time to "jump start" another car. Can't say enough good stuff about this charger.

The clamps are a very important part of this unit. These clamps are designed for top post batteries only. It will not work for side post batteries at all. I have had to make adapters for side post batteries. I'm going to take the clamps off of the old charger and put them on this unit. The clamps are way too cheaply made as well as too small of structure. I'm learning.

Charges my lifepo batteries really quickly without over heating. I have yet to try reconditioning a worn battery. 🤔 Thanks for attention.

I use it at my shop to charge my various batteries. I have one that I had for several years (it’s a different brand but looks the same as this one. The fan quit and I was told parts were not available. If you have fans let me know.

It worked great on my moms riding lawn mower that sat for many months. It took a few hours on the lower amp to charge but once completed it started right up. My only knock is it took a bit of finagling to get it to recognize it was connected to the battery and I had to completely disconnect it but once I did that. No issues at all.

Had a DEAD battery, it seems to have brought it back to life, will be impressed if it has. Will run the charger on it once more . We shall see.
