I have a 1W LED light that feeds from a 3.7V battery pack and charges from a 5V adapter. I believe the DC coaxial is 5.5mm

does anyone know where I can buy a portable battery pack w/ coax connection? I prefer not to use a USB to coax adapter since I'll be wearing it throughout the day. The ebay 1500mah ones don't last me through a working day and the prosumer ones sell for $200+

I'm looking for one that's comparable to the popular portable USB battery packs/power banks that go for $30-50...dimming knob would be a plus but not necessary. Doesn't have to be local ...online is fine.

it'll look something like this

Spoiler!
