What does a USB-C power tester measure?

A USB-C tester sits inline between a charger and a device and reports voltage, current, power, and the negotiated fast-charging protocol (such as USB PD or PPS) — useful for checking cables, chargers, and power budgets.

Is a pocket oscilloscope enough for hobby electronics?

For audio, microcontroller signals, and low-frequency debugging, a compact scope with a few megahertz of bandwidth is often plenty. Fast digital buses and RF work need far more bandwidth, and mains measurements need instruments rated for them — never a pocket scope.
