if you are thinking of a power pack to save you from a dead battery you probably want to carry the unit in your vehicle. This unit uses an AGM battery that does not vent any gasses into the vehicle compartment. I have a van so this is most critical so my children do not get exposed to poisonous gasses. The unit has an inverter with three outlets which are very handy for charging cell phones and running light loads like laptops. It has a light, radio and alarm. The light can run for 50 hours on a full charge. I dont use the radio or alarm but i guess in emergencies I might ????
It can charge through your cigarette lighter while the car is running. The AGM battery also has no charge or discharge current limitations so it can jump large equipment and charge on DC as fast as your system can supply it.
Overall the AGM beats lead acid in so many ways if you can get over the higher price tag. 5 stars.... Get more detail about Xantrex Powerpack 600 Watt Jumpstarter, Power Inverter and Backup Power Source.
