If you usually carry a bottle opener keyring, as so many of us do, then you could be getting so much more utility out of that doodad. A Kanex GoBuddy+ adds an emergency sync and charge cable with either a lightning port or microUSB connector, and yes — a bottle opener. Pretty nifty, right?
It will charge your device, open your cold beverage, and attach via included carabiner clip to your keys.
The Kanex GoBuddy+ is $24.95 for the Lightning version and $19.95 for the microUSB version; both come with that bottle opener keyring.
