USB Port 1800lm CREE XML-T6 LED Bike - Need Power?
I just received this headlamp from China off Ebay and was looking to get the best - lightest - most powerful power source to plug into. All this light has is a standard USB 3 foot cable and came without any power source. I was told that any power bank should work but was looking for suggestions. Please let me know what might work best. Also, just need the light to go for 1-2 hours on a single ride from the power source. Please advise.

Rebuild it with RWC!
never heard of that before. Getting rid of the "cumbersome battery carrying" seems a bit pointless when the light doesn't work without it. Then it becomes "cumbersome dead weight carrying".
If you need a plug and play solution, there are stacks of 18650 powered battery banks/ power packs on Fasttech and eBay, both prebuilt units and empty shells that you can put your own cells into. Usually they're either 2 or 4 cells - more cells = longer runtime but more weight (generalising).
Personally, I'd drop the gimmicky USB connection (unlikely to be either waterproof or all that secure) and wire in a proper sealed cable to use with a proper sealed 3.7V battery pack.
A link to the light you bought would be useful too
I saw this type of light before and wondered why anyone would buy them.
Here's a link to the same style of light
$16.33 POLAR Cree XM-L U2 3-Mode 900-Lumen 6500K Bike Light / Headlamp - 10W / USB powered at FastTech - Worldwide Free Shipping
At least it's cheap.
well I guess that the target of this light is quite small, personally I already own a verbatim 10'000 mah power bank, very light, I keep it in the bike saddle and I can connect 2 usb devices (probably more if I get a usb hub), I don't need the light on a daily basis since I don't use the bike to commute, it's a leisure road bike, hence the reason why a cheap light is enough, it's currently sold at around 13.50-16.00 USD with free shipping.

But I guess that for 13 bucks I can't complain, the only way of getting a proper waterproof light is going for the brand names like knog, niterider, but that would set you back of at least 50 bucks.
