Why in U.S. most appliances do not specify power consumption?

 In China, every appliance has its power consumption (such as 200W for
a TV set or 200mW for a radio, whether it is AC powered or DC powered)
clearly specified straightforward on the exterior packaging box, on
the manual and on the appliance surface sticker. AC voltage (e.g.
220V) and amp (e.g. 10A) are usually also specified.

But in the U.S., it is very difficult to know what a Microwave, a LCD
monitor, a microwave, a heater, a desktop PC, etc., power wattage is.
It is mostly not mentioned anywhere in the online store, retail box,
inside manual booklet or on the appliance itself.

Funny, the vast majority of products sold in the US are made in China

Ummmm.....   This post took me by surprise.

I don't know of any piece of AC operated equipment on the property that
doesn't list the maximum power consumption. That is excluding ones that have
had lost stickers that stated power draw, and equipment I have built.

My old 1950's RCA victor tube type radio has a label stating max power draw.
That being 50 watts.

My old 1980's GE cassette/radio has the label stating max power draw molded
right into the back cover. That being 5 watts.

My computer monitor, my printers, my TV in the living room, and my
refrigerator, and washing machine all have the max power consumption,
operating voltage, and sometimes the max current listed.

Even stuff that operates on 12V is labeled with it's max power consumption.

Like the radioshack short wave radio I am listening to now. It operates on
120V AC and 12 DC. This is what it has on the label on the back. "Power:
120V AC, 60Hz, 13Watts. 13.8V DC, 450mA, Neg Gnd."

So I don't really understand how you can say that equipment in the US doesn'
t list maximum power consumption.

Not true.  _Every_ appliance has a plate stating it's power draw, along with
it's UL, or other standards organization, rating. On top of that, most
appliances have Energy star ratings prominently displayed.

The current draw ratings onthe plate are generally MAXIMUM ALLOWABLE
draw, and can be significantly higher than actual running current -
but that's good because you wouldn't want to plan around average
running current when it can draw significantly more under certain
conditions.

For instance, a PC may have a 450 watt power supply and never draw
more than 95 watts - the tag says 450. It may run at 85 watts when the
CD is not running and the hard drive is not being accessed, and 55
when on standby. Just pulling (somewhat realistic) numbers out of the
air.
