With this Bluebuild, you can charge your laptop with a powerful charger that delivers 65 watts of power to charge most laptops. For large models such as the MacBook Pro 15 and 16 inch, you need a charger with a higher power rating, so take a look at the old charger of your laptop to find out which charger you need. This charger is small, so you can easily carry it in your bag. No charging cable is supplied with this charger. Choose a USB-C-to-USB-C cable to charge most devices. The Bluebuilder never delivers more power than your device can handle. For example, your iPad Pro charges at 30 watts of power and your iPhone at 18 or 20 watts.
