Buying Guide

Match voltage and current to the device

Pick a supply whose maximum voltage and current exceed your device's charging requirements for safe testing and headroom

Prefer USB-C with Quick Charge for speed

USB-C quick-charge ports simplify testing modern phones and tablets and can deliver higher power than standard USB-A

Choose finer control for research work

Encoder knobs and precise adjustment help set voltage/current accurately when measuring charging behavior

Watch total power and protection features

Ensure the bench supply offers adequate wattage and protections like OVP/OVP and current limiting to safeguard devices

Consider size and workspace integration

Compact bench supplies free up lab bench space, while larger units may offer better cooling and longer continuous output
