  • Works great
The product is nicely packaged and came within a day. It is very easy to use and works as advertised. Just connect to a battery and plug it in. The percent charged shows up right on the charger. It is very convenient for keeping my idle batteries charged and ready for use. I would order again.

  • works on all batteries 12volt.
purchased this charger for LIFEP04 BATTERY used in game feeder but found lots of uses. I have lots of equipment that's not used daily. it works on all my batteries so can keep every thing ready to go works great and batteries will probably last a lot longer. compact size long cords.

  • Loud beeps when fully charged
I can’t imagine you will be charging batteries in your bedroom but if so just know that when it’s done charging it gives 3-4 loud beeps. I don’t know if that’s good or bad but I love that it came with a piece to keep attached to battery as well as alligator clips.

  • Not a maintainer!
It says it is a charger and maintainer. Directions say after battery is charged, disconnect. I needed a maintainer. After it showed charged, it continued to flash and beep. I keep a maintainer on my ATV battery all year. I also have two more for my boat batteries that I keep in my garage. The beeping and flashing and no fuse were enough for me to send it back. ... show more

  • Good for small lithium batteries
Used this to charge a lithium battery for my kids' Power Wheel vehicle. In general it works ok, mounts to the wall, and you can cut the wire to make a custom connector. After using it for many months, nothing caught on fire and in general it seemed to work. The main problem I've found is that if the battery is really discharged, this charger doesn't recognize it and won't charge. This happens more often than not. As a result I bought a different charger and I'm getting rid of this one. ... show more

  • The small and practical plus the price which is magnificent.
This charger delivers to the battery exactly the amperes it needs to avoid heating the glasses, I recommend it 100%. I am using it in a 12volt 20 Amp Li-tion battery that I use in an electric reel for deep fishing and it charges it perfectly with trickle charging. It is very manual, light and easy to transport, it can be used to charge the battery of your motorcycle as well as that of your truck, it has helped me with my needs. ... show more
