I have recently purchased a creative HQ-2300D and it only accepts two AA batteries for powering the decoder, there is no DC in on it. Can I use a wall adapter to power it? (it really eats batteries)The intended transformer.nokia charger, output is 3.7v = / 355mAhThe reason I am wanting to use a transformer with it, is it would make it a lot easier as it is only used for gaming on the xbox 360 (to get the dolby headphone from the decoder) so it is never used "on the go" so changing the batteries/ recharging them is a mild annoyance I wouldn't have from a transformer turned on when I use the 360. It can't be as simple as wiring pos to pos and neg to neg on the battery terminals inside the decoder with the nokia charger because there is only a slight variation in the voltage.....can it?. I am also concerned about whether the transformer is regulated or not, reversing polarity, correct polarity etc. etc. and what else is important not important when attempting to do such a thing, so as not to destroy my decoder. (I did this before with a minidisc player and a Universal adapter on the wrong voltage, I didn't impress myself..........doh.... anyone smell that....)I tried plugging the nokia charger into another 3v device (an old sony tape deck) that has a 3v DC in, and it didn't seem to give it enough power to turn the tape, but when I plugged in a universal adapter and set it to 3v it worked fine.My idea is to remove the fem connector from the phone and rig it so it can be plugged into one of the battery terminals and the nokia tranny can be plugged into it, but it can still be removed for when I want to use batteries.I put it to all those with the knowledge who can explain in lay-mans terms and educate me on the best, safest, cleanest way to solve my dilemma.Thanks.
