What it is

The Qyouth US Plug Digital Wattmeter is a 120V, 16A power analyzer that plugs into a standard three-pin outlet. It shows voltage, current, active power and accumulated energy on an LCD screen and can calculate running cost per kilowatt-hour. The unit draws only 0.5W itself and operates from 110V to 130V at 60Hz.

Before you buy

Verify that the circuit you intend to monitor runs on 120V AC and will not exceed 16A continuous current. The display can show values up to 9999V, 9999W and 16.000A, but actual measured power is limited to 3680W. Ensure the device will fit the available space; its body measures 15.50 x 7.00 x 3.50 cm.

Who it suits

This meter suits homeowners, hobbyists and small-business users who want to track energy use of individual appliances or circuits on a 120V North-American supply. It is not for three-phase industrial panels, for loads above 16A, or for installations requiring a certified accuracy class or data-logging interface.

Questions about this item

What comes in the box and do I need to buy a separate plug or cable?

The unit includes the 3-pin US plug wattmeter with integrated LCD display. No separate plug, cable or accessory is required — plug it directly into a 120 V wall outlet and connect the load.

How do I choose between the 16 A and 19 A current ratings shown in the specs?

The meter is rated for continuous operation up to 16 A (max operating current 16 A). The 19 A figure is an absolute ceiling; for regular use stay within the 16 A limit to match the 3680 W real-power ceiling.

What does the 3680 W real-wattage figure mean when the meter is installed in my circuit?

It is the maximum real power the meter can measure accurately on a 120 V, 60 Hz supply. Loads drawing more than 3680 W will exceed the meter’s calibrated range even though the display can show values up to 9999 W.
