Totally waterproof, totally reliable, totally safe! It's not much bigger than a computer mouse, but it packs enough "juice" to keep your ATV, watercraft, or motorcycle battery topped off and ready to go.
The Charger will constantly monitor, charge, and then maintain the battery... even while totally submersed under water.More power:
