For those not familiar with the DR-100, it has 2 XLR inputs and +48 power for them. With a fully charged Tascam Li batt, and two back up AA Ni-MH batts, I can get about 3 hours and 10 minutes out with the phantom power switched on. Needless to say, I've had some REALLY close calls with that battery time. So, I'm looking for the best way to get more juice out of my DR-100 (which I love very, very much) for bands that play long shows, and festival use, etc. My initial instinct is simply buying two or three more Tascame Li batts, that I can change during encore breaks. I also wonder if some sort of small, portable AC power supply pack exists that I can get some juice from while my wall charger is plugged into the DR-100? I want to try to avoid buying a phantom power batt box, just because I like keep lineage as trim as possible, as it's really nice just controlling levels on one machine instead of two. Any ideas?
