There are smartphone cases with built-in batteries to recharge the device when it is running on fumes, but the Megalo Mini is a better alternative. Instead of adding more bulk to one's iPhone or Android phone, the Megalo Mini is touted as the world's smallest portable charger that is tiny enough to hang off of one's keychain comfortably.
The size of a lighter, the Megalo Mini is capable of recharging the iPhone 5 up to 75% and Android phone up to 100%, depending on the model. When in a power lynch, that comes in mighty handy, especially for those who begin to get anxious when their battery dips below 50%. Not only small, but ultra light as well, the Megalo Mini is designed by Michael Krikheli and Jeff Macks.
