It starts to get scary, in how many applications it is used the Cirrus Logic CS5463, an Low-budget AC energy measurement Chip of the year 2011.
Measuring bandwidth for AC = 45Hz to 650Hz.

You may find the Cirrus Logic CS5463 at:
1) Your economy priced Uninterruptible power supply (UPS) this including digital display for Voltage and Watts power.
2) Your economy priced Uninterruptible power supply (UPS) with out display, but when this comes with PC software as electrical energy monitor.
3) Within the most popular Plug-in to mains power energy meter (12 Euro)
4) Within the HOPI 9800, another meter with plastic exterior, sold as power energy meter.
5) Within metal boxes these sold as power energy meter with (low/high) alarm function and LED digits.
6) Within metal boxes these sold as power energy meter with out alarm function and with LED digits.


Low-budget AC energy measurement this is welcomed for consumer level products, it might be accurate just enough so to satisfy simple needs.
Classic light bulb this is a Resistive load, does not create harmonics, it is the most innocent load for connection to the grid.
Power supply for computers, this is another story, more complex one, but active PFC (power function correction circuit) this helps them to improve their ranking condition of a problematic load, in to an less problematic load.

Cirrus Logic CS5463, it might offer Voltage, Current, Watt, Hz and PF measurements, but the manufacturer of a product he is not obligated to use them all.
And therefore, what is of importance here this is the consumer protection from Asian sellers that overcharge pricing.

Plug-in to mains power energy meter (12 Euro), this is now well known, no one will pay 20 or 45 Euro for it, no mater the brand of printed logo.
HOPI another plug-in power energy meter, identical to (12 Euro) plug in meter, yes it does have an little higher manufacturing cost, mostly due it offering of several LED display, instant delivery of all measurements in the unit of time.
 
Metal box power energy meter, with model description 9800 or 9900 (and variations 9801 or 9802, they are all identical.
Another series of budget metal box energy meters, with model description  1010, (and variations 1013 or other) they are all identical.
They are single current shunt devices, according to model, it might include 2A shunt or an 20A shunt.

You need to be very careful with products pricing, when you import from Asia.
Manufacturing cost of such products this vary from  3 to 35 Euro as max.
