Led readout is easy to read and tells when the battery is charged and on auto maintaining the battery charge. I use it for my lawn tractor battery and it works very well.
Simply bought to maintain auto battery, checked on it after three days, zero lights, tried different outlets around the house, no response, unit dead, I think that sums it up!
Patently false advertising. Do not buy this thinking that you will be able to control it via your Smart Phone.
Best value for the money. Love the push button digital feature that tells me my battery power percentage. Keeps your battery @ 100% through the winter sitting in my garage.
I bought this for my riding mower has kept the battery charged perfectly. Used the cable that mounts on the battery for quick connecting. An excellent charger.
