A compact charger small enough for your keychain. It's even called Kii.

I still can't believe how small and smart Kii is, a compact charger that fits right on your keychain. Hence the name. Get it? Now we've loved Bluelounge ever since we featured their CableBox awhile back, and their new Kii falls right in line. It's lightweight and lets you plug in to juice up or sync your devices straight from your laptop -- no jumbled up charging cords or cable connectors needed. Hello, free space. The tote bag hasn't seen you in a good while. Kii is dual-sided: one end is either Micro-USB or Apple connector, the other is USB, to plug directly into your laptop, though it's not recommended for desktops. And the self-locking system ensures that it doesn't slip off your keychain and protects the Apple charging end. Plus, it's teeny-tiny and blends right into everything else on your keychain. Cute and convenient. The Kii is available now on Bluelounge, and prices start at $19.95.
