The charger would be great in itself, but it sounds at higher currents in 230V operation like a midsize jet turbine! It is so loud that it is difficult for a small space, to understand another person good! Besides, for a loader extreme volume I can not fault off, the performance parameters are good and all the necessary accessories is. In order to load two batteries at the same time, one has, to my knowledge, only solder a cable, which also is not a problem. All in all, two stars away for the volume, to whom the matter is, I can only recommend it!
