A typical television draws well under 1 amp. A 55in LED set pulling roughly 90 watts on a 120V US circuit works out to 90 ÷ 120 = 0.75A, and even a large 65in set rarely tops 1.5A. The figure that actually moves is watts, not amps — screen size, panel type and how bright the picture is set all change the wattage, and amps is just that number divided by the 120V a TV plugs into.
Every number below assumes a standard 120V US outlet, which is what a TV uses — there is no 240V television. If you want to convert a spec-sheet wattage to amps for any other appliance, the arithmetic is the same divide-by-120 step; run it through the watts-to-amps calculator rather than guessing.
Amps by size and panel type
Manufacturers publish a rated wattage for each model, usually measured at a mid-range backlight setting rather than the brightest the set can go. The table below uses typical published figures for each category; an individual set can sit either side of these numbers.
| TV type | Typical watts | Amps at 120V |
|---|---|---|
| 32in LED/LCD | 30–55 W | 0.25–0.46 A |
| 55in LED/LCD | 60–120 W | 0.50–1.00 A |
| 65in LED/LCD | 70–150 W | 0.58–1.25 A |
| 55in QLED | 80–150 W | 0.67–1.25 A |
| 65in QLED | 100–190 W | 0.83–1.58 A |
| 55in OLED | 100–160 W | 0.83–1.33 A |
| 65in OLED | 120–200 W | 1.00–1.67 A |
| 42in plasma (older sets) | 200–350 W | 1.67–2.92 A |
| Standby, any type | 0.5–3 W | 0.004–0.025 A |
Two things explain the spread inside each row: the specific model’s efficiency, and the picture settings the set is running — which is worth its own section, because it accounts for more variation than screen size does.
Why panel type changes the draw
LED and LCD sets light the whole screen from a backlight behind the panel, so a big part of their power goes into that backlight regardless of what is on screen — a bright white background can draw noticeably more than a mostly black one, but the swing is modest. QLED sets use the same backlit approach with an added quantum-dot filter layer and usually run the backlight brighter to hit their higher peak brightness, which is why they sit a little above plain LED for the same size.
OLED is different: each pixel produces its own light, so there is no backlight running constantly. A dark, mostly black scene can draw close to nothing extra beyond baseline; a bright, mostly white scene can pull noticeably more than an equivalent LED set. Rated wattage figures for OLED are usually a blend across typical content, so treat them as an average rather than a ceiling.
Plasma sets, if you still have one, run well above every current technology — 200–350W for a mid-size screen was normal, which is 1.7–2.9A at 120V. They were discontinued for exactly this reason.
HDR and high brightness push draw above the spec sheet
The wattage on a spec sheet is measured at a standard test pattern, not at the brightness a set actually runs during HDR content. HDR asks the panel to hit peak brightness levels several times higher than standard dynamic range for parts of the image, and on an LED or QLED set that means driving the backlight harder for as long as that bright content is on screen. It is common for real-world draw during HDR playback to run 30–50% above the rated SDR figure — a 90W-rated 55in set can draw 120–135W during a bright HDR scene. The same applies to a “vivid” or maximum-brightness picture mode left on by default in a showroom: it is the single biggest lever on a TV’s actual power draw, well ahead of screen size.
Standby power is close to irrelevant
A TV left plugged in but switched off (not unplugged, not at a power strip) typically draws 0.5–3W to keep its remote sensor, network connection and quick-start circuitry alive. At 120V that is 0.004–0.025A — not enough to register on most consumption monitors, and not a meaningful contributor to a household bill even for a TV left in standby around the clock. It matters more for the running total across an entire house full of devices than for any one TV.
How much headroom a TV leaves on a circuit
US code limits a circuit to 80% of its breaker rating for a continuous load (NEC 210.20), so a 15A circuit is good for 12A continuous and a 20A circuit for 16A. A TV drawing under 1.5A uses a small fraction of either. The practical question is usually what else shares that circuit — a soundbar, a cable box, a game console and a streaming device add up faster than the TV itself, and a living-room circuit that also feeds a window air conditioner or a space heater can get closer to the limit than the TV ever would on its own. For a fuller picture of what typically shares a circuit with a TV, see the appliance wattage chart; for the appliance that actually stresses a circuit, look at what a refrigerator draws, including the startup surge a TV never produces because it has no compressor or motor to spin up.
Running a TV from a portable power station
Because a TV’s draw is so low, a modest power station runs one for a long stretch. Take a 65W TV, a reasonable figure for a 55in LED set, on a 288 WhWh unit such as Jackery Explorer 300 Plus Portable Power Station ($299): allowing roughly 15% for inverter losses, that works out to about 3.8 hours of playback (85% of the stated capacity divided by 65W).
Step up to a 1,024 WhWh station like BLUETTI Elite 100 V2 Portable Power Station ($499, full details in our power station for TV guide) and the same method gives about 13.4 hours of playback — enough to get through an outage without rationing screen time. A larger OLED drawing closer to 150W would cut that runtime roughly in half on either unit, which is the trade-off worth checking against your own set’s rated wattage before buying a station sized for TV duty specifically.
When you are comparing units on cost rather than just capacity, price per watt-hour is the number that actually predicts value, and it does not always favour the newest model in a range — the power station price index tracks that figure across the current catalogue. If you are sizing a station for more than a TV, start from how to size a solar system or filter by your full load list on the power station finder.
