This may or may not be what you expect. I for one was thinking, all cellphone chargers are portable as long as you can find a power outlet, but this solves even that minor detail.
This charger actually runs on 2 AAA batteries, and what you do is you connect your phone to this Hello Kitty gadget via the connector cable, and it’ll use that power to charge your phone. As for how much it’ll actually charge, apparently there’s a regulation law for that (I don’t see why, but there is) so I can’t really tell you now with my limited Japanese.
As you can see in the picture on the lower right, Kitty’s blushing~ Those red spots are actually LEDs, and they’ll determine how much power is left in your batteries. They’ll weaken as you use up the power, and will completely go out when your batteries are drained or if you disconnect your phone.
It also doubles as an accessory as you’ll see in this page, and I think it’s great just to have around for those critical times when you forget to charge and really need your phone ^^ It costs 998 Yen (only aboutUS$9!) and you can check other purchase details here. ^^
