Kii is a compact charger-connector (Apple Lightning or Apple 30-pin) that fits on your keychain. For the Apple Lightning connector, 2 colors are available, black or white while for the Apple 30-pin only black is available. It seems that EpiCenter is only selling the Kii with Apple Lightning connector (both black and white).
One nice touch that Bluelounge added to the Kii is the self-locking system. You can’t just pull out the connector from the keychain cap, you need to push up the button on the keychain cap to release the lock first before the connector can be pulled out.
