ever had your phone die when you're out & about? worst thing EVER. happens to me pretty much daily. SO guess what.
i found you a solution! a really inexpensive one too.
right now you can get this Jackery Mini Premium Ultra-compact Aluminum Portable Charger for $19.95. it's the world's smallest and only weighs 5 ounces. it will give you 1 full charge to your iPhone and works with pretty much any phone or tablet that charges from a USB port (ipad, galaxy, note, nexus, LG, HTC, etc).
i'm freaking out over this because i kid you not, i almost spent $100 on one of these last week but it was bigger and heavier.
this charger retails for $70 but it's 71% off right now (that's a $50 savings). not sure how long this deal will last so don't wait!
