We've all been there. It's getting late at night and you've been sexting up a storm, but your phone is about to die and you don't know where to meet up. How are you going to find this girl's apartment sans smartphone? Let's be honest, you're useless without Google Maps. Enter the Smartphone-to-Smartphone Charger Cable. The premise here is straightforward: plug your phone into another phone and let the sweet electric nectar flow. It's just $16, bringing it in way below those mobile battery packs. And the cord can stretch up to 30 inches. There's always going to be a phone within 30 inches.
