Review on SUNER POWER Waterproof Battery Maintainer Tools & Equipment and Jump Starters, Battery Chargers & Portable Power by Marcus Dortch

I used the product on a boat in Georgia. Worked great for a week. Then it melted and fell apart. Connected via cigarette lighter. When plugged in, the battery was fully charged. 2 times he drained the battery so much that he couldn't read the voltage on the meter. I thought this product would be a great replacement for marina shore charger. I was very disappointed and became garbage after only a few weeks. It's $50 I'll never get back.
