Plug-in power meter for 120 V circuits

The aFe Power clamp meter plugs into a standard NEMA 5-15 outlet and measures voltage, current, watts, frequency and power factor up to 15 A and 3,680 W. Class 1.0 accuracy with ±0.1 W precision lets you track real-time consumption on appliances running between 110 V and 130 V.

Real-time cost calculator and 90-day memory

Customisable rates from 0 to 99.99 per kWh turn instantaneous readings into running cost totals, while the backlit LCD shows cumulative kWh, peak watts and runtime up to 9,999 days. Battery backup preserves data during outages and overload alerts trigger at 3,680 W.

Verify outlet type and inverter compatibility

The meter only fits NEMA 5-15P plugs and 5-15R sockets; other plug styles need an adapter. It does not operate with AC or solar inverters, so confirm your supply is a standard 120 V, 60 Hz mains connection before ordering.

Questions about this item

Will the internal backup battery need replacement to keep the 90-day data memory working?

The meter uses a built-in battery backup to preserve usage history during outages; no user-replaceable cell is specified in the product data.

At what load does the overload protection trip during continuous operation?

Overload indication activates at 3680 W, which is the first limit reached under sustained use.

How much power does the meter itself draw and how warm does it get when left plugged in all day?

Power dissipation is below 0.8 W, so heat output is minimal during continuous operation.
