Review: Love this little device. I had a lot of chargers and cables that all seemed to perform differently with different devices. With the aid of this tool, I was able to definitively ascertain and verify the capabilities of each charger and cable once and for all.
Review: Sehr praktisches Gerät für USB-C (Lade)geräte. Die Anzeige ist gut zu lesen, auch bei heller Umgebung. Es gibt "USB-C" - Geräte, bei denen nur der Stecker passt aber keine echte USB-C Aushandlung passiert. Diese werden hier sofort "entlarvt", da sich das Gerät dann gar nicht erst einschaltet ;-) Sehr praktisch finde ich, dass das Gerät bidirektional arbeitet - man kann also entweder das Kabel oder die Buchse als Eingang wählen. Die Richtung wird automatisch erkannt und angezeigt.

This little tester is a must-have for anyone working with USB-C charging. I’ve used it to check power output, charging speed, and cable quality — and it gives fast, accurate readings every time. The screen is clear and easy to read, and the build quality is solid. I’ve purchased it twice now and it’s never let me down. Highly recommended for techs and tinkerers.
