has anybody used this 18650 battery power supply/charger to power a bike light or headlamp or charge batteries?

this http://www.ebay.com/itm/280944383829?ssPageName=STRK:MEWAX:IT&_trksid=p3… looks like an option to power a bike light or headlamp. would allow the modder to run the batteries of choice to power a magicshine clone or other budget type haeadlamps. opinions??

Nope, and I wouldn't recommend it. First of all it outputs 5 volts not 3 so it would need a separate driver. It also says that it charges with "DC 5V,1A" and 5 volts is a bit to high of a charge voltage. Well that's just my understanding.

scaru- good catch on the output voltage . didn’t see that! i got the idea from yezl that uses a similiar box to power their bike light and it has a nifty little “dashboard” to control the light. heres the link Loading... i like the magicshine clone headlamps but their batteries are terrible. i could make a pack but i still want to use my batteries in other lights when not using the headlamp.

Well, you could use this with this USB charging board. That could work well.

parts ordered i’ll post when its done. thank you.
