This was well packaged for delivery and comes with the main unit, a micro USB cable and an Apple lightning cable. Some people may find it a little bulky but considering it is 30000mAh it is going to be bigger than some other chargers. So far I have used this to charge a phone around 6 times and have still not needed to charge it up. Overall a fully charged unit could last around 2 weeks charging a mobile phone daily.
