I have a 110 a/h deep cycle battery for long weekend use- it's a bit heavy, but I only need to move it to set up!
I also have a power converter to charge my laptop at 17volts - which eliminates the need to use a power thirsty inverter.
Above that I have a 2kva inverter generator. But I don't expect to use that without dire need.
Power packs are overrated... my small battery is a 7ah gel cell from a scooter.
