We’ve all been there, that dreaded moment when you get the notification that you have 20 percent left on your battery, and your day is nowhere near done. That’s usually the day that you forgot to bring your charger, too. That’s why we’re excited about the new Kii charger from Bluelounge.

Just like its name implies, Kii resembles a key and attaches to your keychain. That way as long as you have your keys (which we’ll bet is 99 percent if the time), you’ll have a charger for your phone. Whether you have the new lightning connector or the 30-pin connector, there’s a Kii for you.

We love the fact that the charger effectively locks into the holder that attaches to your key ring. Try as we might, we couldn’t get it to detach without “unlocking” it by sliding the release lever on the back. This means you don’t have to worry about losing the charger portion when you toss your keys into your handbag. And the fact that this frees us from carrying around a cord, is the best news we’ve heard in a while. Anything device that let’s us streamline the number of things we’re carrying around is a win in our book.

Now, for the two drawbacks: First, Kii is currently only available for Apple devices. We’re hoping they’ll come out with ones compatible for Android and Windows Phone, but no word on timing for that. Second, you’ll still need a USB port. The Kii doesn’t plug directly into the wall outlet—it would be too bulky on your keychain, if it did. But we’re guessing that unless you need to charge your phone while out at a bar or in a coffee shop, you’ll have access to a computer of some kind.

The Kii is available from Bluelounge for $20 for the 30-pin connector and $40 for the lightning connector.
