Teacher’s Comments: Very handy
Here’s a problem that only exists in the western world: You’re out on the golf course and using your phone as a GPS. Halfway through the round, the battery dies and you’re left with the unbearable inconvenience of having to actually step off distances from the nearest sprinkler head.
Fortunately, for every first-world problem, there’s a solution.
The Anker Portable charger is a lipstick sized and shaped battery that can give your phone a boost when you need it most. As you can see from the photo, it isn’t much larger than the phone itself (that’s my Moto X for comparison).
The battery holds a 3000mAh charge, which is enough to fully charge my Moto X and then some. I now keep it in my bag for emergencies.
