Is it Possible for an Appliance have Drastically Different Power Consumption Levels from a Similar Model?

No Stupid Questions@lemmy.world · 6 months ago

Currently looking at TVs and stumbled upon this 55inch TCL model that’s just right for our budget. I noticed though that a similar TV was being sold on a different store which are practically the same (size, display type, panel, software, I/O, etc.) but the average monthly power consumption dropped from 33kW-hr to 13kW-hr (based on 9hr daily usage).

(models of the TV in question is 55p747, 55P735, 54P635. 55P747 was the one that’s exclusive to another store that had the insane power efficiency).

I tried looking at other similar TVs from othwr brands and nothing came close.

How’s that possible?

55P747 had a power input of 49W

while 55P635 had 125W power input.

By which criteria do you determine them to be “similar models?”

The 747 has an LED display, while the 635 is LCD. The former will be inherently more power-efficient.
