As technology changes and adapts, so does Adafruit, and speaking of adapting, this adapter has a 2.1mm barrel jack socket and a USB C plug — you could use this to power a USB C device from a common wall adapter.
USB C is the latest industry-standard connector for transmitting data and power. Like Lightning and MagSafe cables, USB C has no up or down orientation. Plug this adapter onto the end of a 2.1mm 5VDC barrel jack, and now it’s a USB C however please be aware there’s no protection circuit or Power Delivery negotiation, you really should only be using this with a 5V adapter but if you have the wrong polarity or voltage, you could damage your electronics!TECHNICAL DETAIL
