About this deal
The Satechi Duo has two wireless charging pads (the main one supports up to 10 W charging speeds, and the other up to 5 W) as well as a USB-C PD port that can charge a third device or the power bank itself at up to 18 W.
And as you pointed out, could very well be a mistake on their end when designing and building phases. With wireless, USB, and USB-C charging all available, PowerCore gives you unprecedented choice over how you charge. The Anker 621 Magnetic Battery (A1610), Anker 622 Magnetic Battery (A1611), Anker 622 Magnetic Battery (A1614), and Anker PowerCore Magnetic 5K (A1619) are lighter and cheaper than our picks, but they have half the capacity and no additional features.
With the terrible excuses aside, I learned what I want in battery banks as I have tried many in the past.
Dropping one of the USB Type-A ports and making the USB Type-C function as both an input and output for power is also a solid move. In addition to a MagSafe wireless charging pad and USB-C PD port, it gives you a USB-A port to charge a third device.
It isn’t WPC-certified, but none of our picks are (and we didn’t notice any safety or performance issues in our testing).
