One of the last things you want to do when you’re on the water is have to take time to charge your battery. Powermania's Turbo M220V2 Battery Charger is waterproof, corrosion-resistant and shock-resistant, making it ideal for recharging batteries for marine applications. This charger is based on the same compact design as the first generation Turbo M220, including its ability to maintain 100% output at 90V AC, to charge 0-volt dead batteries, and to cleverly allocate more power to batteries that are more drained for a quicker recharge. Improvements in the design include running up to 25°F cooler, weighing 25% lighter, and offering error check and charge status for each individual output.
