I have a Black and Decker Power Monitor model EM100B. It works reasonably well and it was interesting to see the A/C using between 2.3kw and 2.5kw depending on outdoor and indoor ambient temps. The bad thing is the real-time data has a 300 watt minimum so it will cycle between 0 and 300 watts if the load is low, which for my house is always unless I'm running something with high-load (fridge defrost coil, laundry, kitchen heating appliances, dishwasher, a/c, etc). Kill-a-watt works better when monitoring small loads as its far more accurate and specific to what it is connected to.

Mounts to the power meter and an IR eye reads counts the rotations. Also works with electronic meters by pointing it through the diagnostic hole where the electronic meters blink.

Here's the box.

Bought it used for $32 but they can be found for about $50 new.
Eventually I will sell this and get a TED since it reads current both ways for when I get solar electric PV panels installed.
