Most nights we have on USB charge some combination of:
- Phone
- Girlfriend's phone
- Kindle
- iPad
- Nexus 7
- GoPro
- MP3 player
It's already a mess of cables.
What I want are higher capacity batteries that last longer (get charged less frequently) and that I can swap out for spares. What I want are batteries that charge faster and can discharge faster (higher voltage) so that the lights are bright.
That exists today, they're called CR123 batteries. They charge fast, hold a ton of charge, and can power really bright lights (my torch uses one and goes to 500 lumens).
So yeah... USB charge can >>>>>>>>>>>>>>
I liked the Moon for brightness and cheapness, but when I can afford to I'll go back to Exposure for battery support + brightness.

I prefer keeping a wall charger with an extra set of AA batteries on the ready, then change batteries before I ride. Relying on USB charging requires the self discipline to put my lights on recharge when I return from a ride. Usually when I get back home I'm dying for a snack/piss/shower/dry clothes/beer/etc. ... I know my limitations.
Limits my choice of lights though...

I only use mine for racing so it's fine, but I think I'd get annoyed with the battery life if I was commuting with it. Surprised you'd find USB charging a problem, you must have a USB wall adaptor?
