Review on Yinleader Inverter Converter Intelligent Display Tools & Equipment and Jump Starters, Battery Chargers & Portable Power by Otto Barkley

As a result of using this product, I found that it lacked the promised power and speed. It didn't work well for automotive BATTERIES and took ages to charge .The intelligent display tools were confusing and not helpful. The only pro was the portable design. Overall, a frustrating purchase that didn't live up to its claims..
