Hi all, Just bought one of these http://www.amazon.co.uk/Digital-Power-Amplifier-Module-Supply/dp/B00HCB8CIW/ref=sr_1_16?s=electronics&ie=UTF8&qid=1397413999&sr=1-16&keywords=usb+amplifier and I would like to take it out with me when I go out on the old bmx. Kinda need it to run for a few hours at modest volume, would one of those usb charging packs be ok for this?

I have done it before with a cheapo pack. Exactly the same amp. Works perfectly. Infrasound: It can only deliver 3 watts. In my experience it works without any problems on a standard 500mA source.

Cool stuff, Currently running it from a htc charger rated 1a, it seems to be doing fine. I think I'm gunna go for a cheapo pack but all the figures seem a tad on the bloated size...

You could look for a Romoss or Cager powerbank. Decent but cheap.

Shielded wire can prevent interference. I think that's what they meant to say ^^
