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.

Gute Qualität und Verarbeitung, wird mit einer (schwer zu öffnenden🔒) Aufbewahrungsbox geliefert. Misst zuverlässig die Ladegeschwindigkeit und zeigt die Kapazität meiner Powerbank nach vollständiger Aufladung an. Jetzt sortiere ich die Kabel die nicht fürs Schnellladen geeignet sind aus. Für den Preis würde ich es wieder kaufen.

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.
