But if you loser power for several days because of a weather event, act of terrorism etc., there will be no way to keep your laptop charged! Or the products listed above, both of which appear to have internal rechargeable batteries.

I am talking about a digital TV powered by D cell batteries with an alternative AC power cord! Both of the models that are linked above have rechargeable batteries. The product that I think is needed is one that can be powered on replaceable D cell or C cell alkaline batteries!

There is a big market for this product!
