waltmon -- you may be able to pick up a reasonably cheap charger + correct sized tip at Radio Shack, if you absolutely must get it charged. If the specs for the Naztech are correct on Amazon, you'd need a 12V / 2A charger. I don't know if positive (+) is ring or tip, but it's usually tip. But not always. Someone with the Naztech charger + a multimeter could check for you in a matter of seconds.
The Naztech 15000 is rated at 55.5Wh. Watt-hours (Wh) / Volts (V) = Amp-hours (Ah).
For 6V V2: 55 Wh / 6V = 9.25 Ah. V2 draws ~0.5 A (taken from the V2 manual). 9.25 Ah / 0.5A = 18.5 hours. That's purely theoretical. Assume maybe 75% of that to account for real world v. theoretical (e.g. the efficiency of the DC-DC converter, or whatever implementation allows the Naztech to output a variety of DC voltages). So 18.5 hr * 0.75 = 13.875 hrs.
For 12V Minime: 55.5 Wh / 12V = 4.625 Ah. Minime draws between 1-2A (from the Apogee site). If we assume the low end of 1A: 4.625 AH / 1A = 4.625 hrs. Again, that's theoretical. Probably 75% of that is a conservative estimate, or 3.47 hrs.
The amperage draw of the mics you're using matters, so the above may be high or low for your application. Only way to know for certain is to test your own gear under controlled circumstances. But as a ballpark figure, based on a full charge of the Naztech, the above may be helpful.
IME, bar indicators for remaining battery capacity are notoriously inaccurate and often not linear. So 2/4 bars may not mean you have 50% capacity remaining. It could just as easily mean you have 24%, or 27%, or 60% remaining.
