## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4232:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA4232:1.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. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

While this may appear to be an electronic [shuriken](https://en.wikipedia.org/wiki/Shuriken), it's actually a **Multifunctional USB Digital Tester**!

This handy (pun intended?) tool can measure voltage, current, power, charge time, and other measurements for **USB A, Micro B, and USB C**! It features a colorful display that pops up when you plug in a power supply. Each click of the button gives you a different display and readout. A long press will reset the data for when it does Coulomb-counting (total power consumption). Adafruit like the simple display that comes up first with big Voltage and Current output, but you have lots of options.

There's 4 connectors so you can go from type A to C, type A to A or type C to C.

Works great with laptops, smartphones, tablets, what have you, it's perfect for testing any USB power setup but this model is a little nicer in that it is also good for USB C with its higher current and voltage capabilities - up to 32V and 5A!

If you're using this to test USB C be sure to [get a cable with E-Mark power negotiation chips inside so you get the proper current and voltage out ](https://core-electronics.com.au/search/?q=e-mark)- many cheap USB C cables skip this part and won't work well for high-current/voltage charging.

## Technical Details

- Tester Dimensions: approx 68 x 60mm / 2.6" x 2.3"
- Voltage Range: 3.6V~32V
