Hi y'all. New member here. I did some searching already, and found lots of related info on this BUT I'm a bit techno-challenged and hope someone will chime in to clarify things for me.
I am looking for a battery power supply and an AC adapter to power a Tascam DR-40 audio recorder, via the DR-40's Mini-B USB port. The DR-40 ships with 3 non-rechargeable AA's batteries, but I realize these won't have a long life using phantom power to power condenser mics connected to the XLR's. In some cases, I will have access to AC power, so an AC adapter would be nice. The manual suggests that the DR-40 can't be used to recharge batteries, so I'm also interested in a remote battery option that is rechargeable.
I am not sure of how to decipher the requirements for this device, nor am I confident about how power is handled via USB. FWIW, the PS-P515U product photo shows "+" and "–" polarity for the two outer USB pins. Tascam sells an AC adapter (Tascam PS-P515U SA1078-05U) but I'd like to know if there are better options to consider.
Per the PS-P515U product photo, the specs of the Tascam unit are DC 5V 1.5A 7.5W, and the DR-40 manual states the device draws 1.7 W.
BTW, I have an Apple A1357 AC / USB adapter that came with iPod Nano. Here's the specs I found for it:
Input: 100-240V ~ 0.45A (0.45A) 50-60Hz
Output: 5.1V == 2.1A
10 W
Could this be safely used with the DR-40?
Thanks in advance for any info you can offer!
