A Larger battery is the best way to buy this product
My Battery only last 2 hrs on 2 liters so if you know how long you will be away then plan accordingly

Very pleased with the unit
Very pleased with the unit, but on battery it runs for approx. 15 min and shuts off. Just restart and runs for another 15 min. Looking for an adjustment to keep it running, haven't found it yet. May a heat problem.
