It's two days that I served and perfectly meets my expectations. Simple to use, it recharges the batteries in 4 phases. The mode selection button controls: slow load 6V, 12V load slow, fast charging 12V and load t ° Cold 12V For me, the big plus is the screen that informs it is charging or maintenance phase and voltage in real tps of the batt (there is thus an integrated voltmeter). Also, if there is a power failure, the case can store (max 12 hours) or phase it was and that the current is re established, charging resumes. I did this time and no complaints given the price, I definitely recommend.
