SahmSparks YLY0100 Lipstick 2600mAh External Battery Power Bank for Smart Phones and Tablets - Light Green Never feel powerless at an airport with this 2600 mAh attractively designed cell phone charger, which is a cell phone travel charger, but equally good at work or the home when you need that extra juice without having to plug in just yet. Or, how about when you're out jogging? Remember, your iPhone -- or mobile device -- is only as good as its power supply. Never fumble with tiny on/off buttons in the dark. Our innovative design -- evolved simplicity, we call it -- has eliminated the tyranny of the tiny button. Put yourself into a productive mood. Get your personality back with our better design and the fresh green colour. Stop suffering unimaginative technology. Just plug in (with the micro USB cable) and use -- after the first full charge (2-3 hours; this requires your own iPhone cable) of course. And, once fully powered up thus, stay charged for 3-15 hours. Never feel anxious about overcharging, either. Our IQ circuitry keeps you safe. Charge more than 500 times over the lifetime of the charger.
