Read the Efficiency Grade and Rated Power Consumption of an Electric Rice Cooker

Key Takeaway
Match a rice cooker's cooking capacity first, then read the efficiency grade and rated power. The agency list shows rated W, capacity, and grade, but rated W alone can't give the energy for one cook or keeping warm.
What do you check first in the rice cooker list?
Check the last letters of the model name and the cooking capacity first. Even among 6-cup models from the same brand, different names mean separate products. In the Korea Energy Agency's electric rice cooker product search, look at rated power consumption (W), cooking capacity, and efficiency grade together. If you pick only the candidate with the lower W without deciding the cooking capacity you need, the amount you want to cook at once drops out.
In the agency list on October 8, 2026, the CRP-DHP0610FD and CRP-DHAS069FW both showed a rated power consumption of 1,090W, a cooking capacity of 6, and an efficiency grade of 1. Their application numbers are 295250313 and 295250311 respectively. This list gives no basis for saying that one of two candidates with the same grade and rated value always uses less electricity when cooking.
How do the two candidates' official manufacturer specs differ?
| Model | Official capacity | Official power consumption | Size as labeled by manufacturer (mm) | Weight | Agency efficiency grade |
|---|---|---|---|---|---|
| CRP-DHP0610FD | 6 cups | 1,090W | 378×266×256 | 6.3kg | Grade 1 |
| CRP-DHAS069FW | 6 cups | 1,090W | W378×L266×H256 | 6.3kg | Grade 1 |
The official Cuckoo product pages and the Korea Energy Agency list are as of October 8, 2026. See the price on the sales page of the purchase link. The DHP page gives the size as 378×266×256mm and the DHAS page as W378×L266×H256mm, so I left each label as it is. When fitting it into a cabinet, recheck the per-direction dimensions and the room needed to open the lid in the model's installation guide.
The CRP-DHP0610FD official page describes a coated stainless steel inner pot, and the CRP-DHAS069FW official page describes an all-stainless steel inner pot. This difference matters when you weigh care methods or personal taste. It is not a basis for saying either of two candidates with the same energy figures saves electricity, so don't read the inner pot material as a ranking of electricity use.
Does a rated 1,090W mean 1.09kWh per cook?
No. W is power consumption, and kWh is energy used over time. The rated number doesn't contain the cooking time or heating state of a single cook, so you can't read 1,090W as meaning one cook costs 1.09kWh. The actual energy for keeping warm isn't set by this rated number alone either.
If you assume it runs at a constant 1,090W for a full 30 minutes, you can make an arithmetic example of 1,090÷1,000×0.5=0.545kWh. But it is not a measured cooking time or cooking energy for the two models, and it doesn't mean the product holds its rated W for 30 minutes. If you carry it over as a product spec without the assumption, it will cause misunderstanding.
If it's grade 1, is the keep-warm energy the same?
Not necessarily. From the same grade and rated value in the agency list, you can't say the two candidates' keep-warm energy is the same, and this table has no values comparing keep-warm time and state. If your household keeps rice warm for a long time, check the keep-warm conditions in the model's manual and, if needed, find out the energy under your actual usage conditions separately.
Read it together with how to read efficiency grade numbers for the basics of reading grade labels. For a rice cooker, a starting point is to read capacity, rated W, and the time basis for using keep-warm as separate things. A single grade doesn't explain the energy of every way of using it.
Which one fits your household size and space?
If you are looking for a 6-cup model, set the two models at the same capacity and compare size and inner pot care conditions. The official dimensions and weight are the same, so you can't say one is lighter and easier to move. Decide on the inner pot material after reading the manufacturer's care guide.
If you need a capacity bigger than 6 cups, these two candidates aren't the answer. When putting a rice cooker under a shelf, don't decide it can be installed from the body dimensions alone either. The room to open the lid and the steam release conditions are things to check separately in the model's guide. If you settle the amount you need to cook and the spot to put it first, even candidates with the same grade are easier to narrow down.

Frequently Asked Questions
Does 1,090W mean 1.09kWh for one cooking cycle?
No. Without the cooking time and operating state, you can't read W as the energy for one cycle.
If the grade and W are the same, is the energy for keeping warm the same too?
You can't confirm that the keep-warm energy is the same from the agency's grade and rated values alone. You have to check the actual keep-warm conditions separately.
Do the two candidates differ in capacity and size?
Both are officially 6-cup models, with a size of 378×266×256mm and a weight of 6.3kg. Check each manufacturer's guide for how the dimension directions are labeled.
