How do I charge the EverStart Maxx Jump Starter?

Plug the Micro USB end of the charging cable into the input port on the jump starter, then connect the USB end to a charger's USB port and plug it into a live AC or DC power outlet. The jump starter will fully charge in approximately 4 hours with a 2A charger. When fully charged, all four blue LEDs will turn solid for a short time and then shut off.
