While conferences are a great way to learn and share new information, they're also a drain on your mobile devices. There are portable battery chargers available, but if you forget to pack one, or don't charge it up before you go out and about through Austin, you could find yourself without any way to use your mobile devices.
If that's you, Mophie has you covered! If you notice that your phone is about to go dead, simply send a tweet to @Mophie with the hashtag of #MophieRescue, along with your location, and one of these St. Bernards will try to find you to give your mobile device a jumpstart. This is all for a good cause too: Mophie is letting people know about the fact that you can adopt these dogs and bring them into your home.
Sadly, all the St. Bernards offer is battery power. You'll have to find your own alcohol, but with a bar on practically every street in Austin, you don't have to go far.
