Good product

Very good product, charges my 2 1800 w batteries within an hour. Only down side is it gets pretty hot when it charging which may be a hazard so I'd recommend not leaving it unattended.

This thing is bad ***. Charges real quick, has a USB port on the side to charge a device off the batteries if need be or if it's plugged in. Comes with a car adapter. Works with every size battery. Awesome charging station.
