Xantrex Powerpack 600 Great product, but missing one thing..

I have loved these power packs for years, and every time they have come out with a bigger one I was the first to buy it. but this one was a slight disappointment only because it does not have the air pump. Every one I have purchased in the past had one, and believe me they have come in handy. From pumping up things around the house or office to having a flat tire at 2 am in DC just to find out your spare tire is under inflated... I think it's a pretty handy thing to have. My guess would be that they left it off to keep the weight down, but who knows. I still love this product though, but I am going to purchase a small air pump to keep with it in the car.
