I bought this to charge
I bought this to charge an iPad via UCB-c connector and an iPhone 12 through an Apple Magsafe charger. The iPad charges fine, but the Apple Magsafe charger doesn’t really work. When the Magsafe is plugged into the Hyperjuice 66 W, the iPhone claims its charging but a few hours later the iPhone has less change than when it started. It seems to lose connection within a few seconds. This is with the iPad not attached to the Hyperjuice. I also found I got no charging if the Magsafe was plugged into the top USB-c port on the Hyperjuice. The Magsafe works fine with the transformer from Apple, so it is not a Magsafe issue.
