Slow or worse
Pretty compact. And cheap! A bit slow. But $20! It brought my battery up from 12.9 to 14.3 overnight. I'm heading on a cold weather trip soon and wanted my lithiums topped off to run the furnace for overnight stops. I'm happy with purchase. It suits my purpose.

Good charger, needs more connection options
Used it twice now on 2 different lithium batterys. Juiced them up in an hour, both were already somewhat charged. I wish it had a connection with options for ring connection and clamp.

Very good L-ion 12v charger
Very accurate self regulating 12v lithium ion charger. Highly recommend purchasing.

Works so far
Used this to charge a 12v 100ah battery. It works just fine but it's certainly not putting out 10a. It will take around 12-13 hours to charge a 100ah battery with this charger.

Unhappy charge
I ordered this because I ordered a lithium battery through Amazon the battery doesn't work the scooter that they said would work so now I'm stuck with the battery as well as the charger.

12V Lithium Battery Charger 14.6V 10A LiFeP
I hard wired this charger into a backup battery power for my house. Although it says not to alter the connector wires it seems to be working fine to supplement solar charging in maintaining charge when needed under light usage.
