Have you ever used one of these portable chargers? They are SO handy! Especially when my son forgets to charge his phone and he needs to charge it in a hurry. I love them! This Ravpower Portable Charger has iSmart technology, which means it detects the device and delivers the optimal charging current to the device, ensuring a fast and efficient charge. This nifty little device can charge an iPhone 6 nearly 6 times! How cool is that?
