Works with any iPhone with Lightning Connector so iPhone 5's and iPhone 6's. 4000mAh is about 160% charge for iPhone 6 and full charge for iPhone 6 plus. The tip is MicroUSB out to Lightining Tip. Would need a MicroUSB to MicroUSB connector for non-Apple. Made with Lithium Polymer vs. Lithium Ion and made at same Energizer manufacturing facility so lighter, last longer and will recharge 4-5X more times without degradation that equivalent power packs. So a very good value that you can rely on.
