Item was delivered very fast to my address.
The directions stated it had to be charge it up before using even though the check lights indicated it was already at full charge. So far the unit seems to be working. All the lights and the usb ports are working. The air inflation works too, but is very noisy. I have not tried to jump start a car yet though. I am suppose to also do a once every 30-day upkeep recharge on the battery, which was a little unexpected.
