TCL TAC-09CWI/UJE2 Power Consumption: Watts, CSPF and Monthly Cost

The TCL TAC-09CWI/UJE2 is a 1HP inverter window aircon rated at 733 W on its DOE energy label, with a CSPF of 4.88 and 5 stars. That makes it the lowest-wattage verified 1HP window unit in our data. You can find it at the TCL Official Store on Shopee and the TCL store on Lazada.

What it costs to run each month

The simple formula is:

monthly kWh = watts × hours per day × days ÷ 1,000

For a bedroom used 8 hours a night for 30 days:

• At full rated power: 733 × 8 × 30 ÷ 1,000 = 175.9 kWh. At an example rate of ₱12 per kWh (use your own bill’s rate), that is about ₱2,111.
• If it averages half its rated input once the room is cool (an example assumption, the same 0.5 factor the label uses for inverter units; real use varies): about 88 kWh, or roughly ₱1,056.

Each hour at full rated power costs about ₱8.80 at the same example rate. Check your electric company’s current rate on our electricity rates page, then try your own hours in the aircon electricity cost calculator.

How it compares with other 1HP window aircons

The UJE2 and the UB2 have the same 2.6 kW cooling capacity, but the UJE2 is rated at 117 W less input. So why does the UB2 have the higher CSPF? CSPF measures efficiency across a whole cooling season, including part-load running, while the rated watts are measured at one full-load test point. The UB2 scores better over the season; the UJE2 draws less at the rated point. Over many hours at part load the gap between them in pesos is likely to be small.

The Kolin KA-100GQAIINV32 draws almost the same rated watts (740 W) but delivers more cooling (2.86 kW) and has a higher CSPF (5.6). Its label shows 4 stars, but that label uses newer star bands, so don’t read it as “less efficient” than the UJE2’s 5 stars. Compare the CSPF numbers instead. Our inverter vs non-inverter guide explains how to read these figures.

Who the TAC-09CWI/UJE2 suits

• Small to medium bedrooms within the retailer’s 9–16 m² range, where a window opening already exists.
• Buyers comparing on rated watts, because 733 W is the lowest rated input among the verified 1HP window units here. (Like any inverter, it can draw more than this while cooling a hot room down.)
• Buyers who want a 5-star inverter window unit from a brand with an official store on both Shopee and Lazada.

If your room is at the top of that size range or gets strong afternoon sun, the higher-capacity Kolin may hold temperature more easily. For a larger room, step up to a 1.5HP unit such as the TCL TAC-12CWI/UB2.

Have the unit installed by a licensed technician or the brand’s authorised installer. A poorly sealed window frame lets hot air in and raises running costs. More ways to cut aircon use are in our aircon electricity consumption guide.

Where to buy

• TCL TAC-09CWI/UJE2 on Shopee (TCL Official Store, UJE2 series listing: choose 1HP)
• TCL TAC-09CWI/UJE2 on Lazada (TCL)

Alternatives with a higher CSPF:

• Kolin KA-100GQAIINV32 on Lazada
• TCL TAC-09CWI/UB2 on Shopee · on Lazada

Check today’s price before you buy. On the Shopee series listing, confirm the selected variant reads TAC-09CWI/UJE2 (1HP).

Bottom line

The TCL TAC-09CWI/UJE2 is a 5-star, 733 W inverter window aircon with the lowest rated input of the verified 1HP window units we checked. If you want the highest seasonal efficiency instead, the Kolin KA-100GQAIINV32 and TCL UB2 rate higher on CSPF. Whichever you pick, work out your own monthly cost with your actual hours and rate.
