I think having the new 110V converter is awesome, and I'm very happy this product came out. I will be getting one on Wednesday. I have a 12V cooler which I have wanted to find something to be able to run, and this will be perfect. When going on trips, I think this will be a very nice product, however, the only chargers available for the batteries are quite bulky. If trying to travel with limited space, I think it would be great to have a very small "slow" charger -- something that would refill a battery overnight. This would keep the packing volume down if you wanted to take some batteries with the 110V inverter attachment. Many other competitor products have small slow chargers and larger fast chargers.
