Saved my dead battery!!
This is the easiest to use. Two steps: Connect to dead battery. Plug it in. It detected the type and condition and went at it. Next day I saw that it had finished. The car is still operating as normal. :)

Easy to use at a great price
Took it out of the box, plugged it in, hooked it to the battery, and it was charged in minutes. Finally, a charger I don't need tech support to use.

Quality made
This charger works great. Charged up my lithium battery and shut off on its own.

Not as advertised. Not reliable.
This battery charger is advertised as having a 20A maximum rate of charge. I bought it to charge a 100AH LiFePO4 battery. Once plugged in, set to LiFePO and then connected the unit starts charging for several minutes at 3.1A then gradually ramps up over several more minutes to 13.1A (The display reports it is delivering 19.8A but it is actually only 13.1). Charge rate never exceeded 13.1A over several hours. So this unit was not as advertised. Then the internal cooling fan ceased operating and the unit got quite hot and the charge rate dropped back to 3.1A. I let it cool and started charging again but the fan never came on and the charge rate remained at 3.1A. The unit has failed after 1 day of use.

Does the job
Works fine. Display messages are not as intuitive as one would wish and control is limited to choosing the type of battery you want to charge, but otherwise it's self-explanatory: plug in the charger, connect its clips to your battery, press the only button to change the choice displayed -- successive button presses take you through the list of choices.(Have tried it only with a 12V car/marine battery, which it charged from below 10% to 80% in about 45mins, charging at 20amps for most of that period.)
