Power shortages never have good timing, and that’s as true of our personal devices as it is of city blocks. If you’re lucky, or planned ahead, you might find yourself able to plug in when the juice runs dry. But dead batteries have a habit of sneaking up on us, so there’s no such thing as being too prepared. You don’t leave home without your keys, so why should you walk outside without power?

The AtomXS Emergency Keychain Charger connects easily to the one thing you’re most likely to always have within reach: your keys. That means whether you’re out on a job, late for a date, or hiking in the woods, you’ll have backup power when the need arises. To turn it on, just press the big button sensor down for 3 seconds. With a 1,300mAh battery capacity, you get more than 3 hours of charging time for your smartphone. Its charging tip is retractable, so you won’t have to worry about scratches or dents if you drop your keys. All that in a handy, smooth circular design. And don’t worry if you’re not an iPhone user, there are three plug varieties.
