2017 MacBook 12-inch Retina

This is a great UPS. I connect my old iMac & Wi-Fi router. It will last about 15-20 minutes when the power runs out. It gives you enough time to power down your computer, so you don't lose anything. It will start beeping as a warning when the battery is very low. You can always buy a replacement battery which is much cheaper then buying a UPS. I'm moving. I have the original box
