- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA4536:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged.

## Description

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!

Works great with any device that has a USB C port and does not require a USB Power Delivery chip, such as the Raspberry Pi 4. To match, you can use Adafruit's 2A 5V wall power supplies!

Product Weight: 9.0g / 0.3oz
