2UUL PW11 Power X High Refresh Screen Ampere-Voltage Meter

A fast-refreshing current display is valuable on the repair bench, because the interesting moments in a phone's boot happen in fractions of a second. The 2UUL PW11 Power X is sold as an ampere-voltage meter with a high refresh screen, though its listing says very little about the PW11 itself.

The listing describes 2UUL ampere-voltage meters in general: they measure current and voltage, have a digital display, range selection and overload protection, and typically run on batteries. It doesn't give the PW11's ranges, refresh rate, connectors or how it attaches to a power supply or phone.

When an ampere-voltage meter helps

• A phone that won't boot and you want to watch current at power-on.

• A short that pulls current with nothing on screen.

• Charging faults where current and voltage tell you where to look.

• Teaching how current changes through a phone's boot sequence.

Before ordering

Check the photos for the display, ports and connection method, and confirm the measurement range covers the currents you work with. The generic description isn't enough on its own to judge whether it fits your bench setup.

Whatever meter you use, note the normal readings of known-good phones. A fast display only helps if you know what healthy looks like.
