Review on LUNDA Smart Battery Charger: Efficient 12V/24V Automotive Charger for Car, Truck, Boat, Motorcycle, and RV - 400Ah Maintainer and Trickle Charger by Michael Vargas

The suffix is misleading. This charger is 12V 15A / 24V 7.5A 180W. The digital display shows an incorrect battery voltage, 0.8V at 12V and 0.5V at 24V. The power wheel on the front does nothing at all , as far as I can tell. When connecting wires to the battery when it is disconnected from the wall, sparks will occur. The battery charging voltage is 14.7V. It works and charges the batteries, but I managed to charge 6 batteries at the same time, it doesn't have enough current to do the job I was told. I needed 20 amps at 24 volts which he claims to have. If you only need to charge a small battery, it may be fine. Perfomance.
