Thank both of you very much!! I didn't know that there are such things at all!! Your information really helped me. Especially, Mark, TekCharge MP1550 really seems what I was looking for. It meets all of my needs. Even, the price of it plus 4 Ni-MH batteries is less than just half of the price of a Li-ion battery pack in the market now, following my search today. I think that I don't need a expensive Li-ion or Li-polymer external battery and Ni-MH is enough for my use for DR1000S, so it'll actually save much of my money. Although I think it is a very good product, it or similar ones are not being sold here. Thank you again, Mark.
