The keychain is a useful place to keep tools of all sorts. I happen to have a multitool, a bottle-opener/belt-hook, a pen, and a titanium wrench/pry-bar combo, because I am an enormous nerd and, sadly, I have occasion to use all of that crap on at least a weekly basis. This isn’t even getting into the tools I replaced with my smartphone, like a flashlight. But even if you are not an enormous nerd, you might want to consider putting a Kii on your keychain, because it means you’ll always have a charger on hand.
The Kii is actually incredibly clever, in terms of design. It looks like a novelty USB drive at first glance; it’s made of grey plastic to look like a key, and has a full-sized USB port where the teeth would normally be. However, a quick tug on the top of the Kii reveals either a 30-pin connector or a Lightning connector. Sorry, Android fans, or people who need to have data transfer for their camera, there’s not yet a micro-USB or mini-USB version. So, if you need to charge your iPhone, and you happen to be near a USB port, powering up your phone is as simple as pulling out your keychain.
It’s a little surprising somebody took this long to come up with the concept. True, we’re not always near a handy-dandy USB port, and it does rely on being able to rest your phone somewhere. Also, we hope that USB connector has a plastic cap because otherwise it’s going to collect pocket lint like nobody’s business.
But that said, being able to get a charger on your keychain will be incredibly useful, especially if your phone keeps dying at work. The Kii will run you $20 for a thirty-pin connector, and $40 for a Lightning connector. But hey, again, no dead phones!
