Brand new MagSafe battery pack for iPhone 12 and newer. This is a generic, unbranded product. This battery pack is on the thicker side, so I wouldn’t purchase if you’re looking for something on the really slim side. I have shown the measurements in the pictures. The battery capacity is listed as 10,000 mAh but I would say it’s more along the 5,000-7,500 range. It will definitely charge your phone at least once but it may or may not do it twice. Overall a very nice product that I use myself. Thank you for checking this item out.
