TV and also other similar multimedia devices are a very important part of ours lives and many civilization wonder around the power requirements of your TV sets, not just for off-the-grid situations, but likewise in bespeak to an ext easily estimate their electric bills.

You are watching: How many amps does a flat screen tv use

TV wattage counts on the display technology, provided brightness, contrasts, just how loud is the sound and similar. Also, part TV systems are connected to exterior sound systems that frequently require much more power than the TVs...

Published: February 23, 2021.


The most common TV display screen technologies today are LCD, LED, OLED, QLED, etc. With plasma screens and also especially CRT (Cathode ray Tube) screens being phased out.

In bespeak to identify the exact power requirement of any TV unit, the finest thing to perform is to inspect the brand at the back of the TV and/or to examine the documentation the came through the unit.

Similarly, if an outside sound mechanism is used, be sure to inspect its power requirements.

If You intend to use your TV throughout a power outage, and your TV uses external decoder/receiver/router or whatever piece the external tools these work TV cable carriers use, be sure to inspect its strength requirement too - in this case, likewise check through the cable agency if they send a signal come the users during power outages and also if lock do, for how long.

Depending ~ above the TV an innovation and TV display screen size, typical TV power usage is offered in the adhering to comparison chart:

Again, this are simply "average" values - that is not the very same to reduced the volume and also slightly diminish the brightness, and also to "burn" subwoofers and also to use the TV screen as second source the light.

How numerous Watts go a 32-Inch TV Use?

32-inch TVs are an extremely popular and also commonly offered as the key TV in smaller sized homes and also apartments, as TV because that kids" rooms, together camping or RV TV and also similar.

Depending top top the technology, 32-inch TV requires:

- 32-inch LED TV: 40-45 watts,

- 32-inch OLED TV: 55-60 watts,

- 32-inch LCD TV: 65-75 watts.

We must emphasize the these are just some mean values - your TV perhaps uses very energy-efficient an innovation and probably requires even less power. Or, you are using some external device that maybe requires much much more power than the TV itself.

Note: If You have actually an older plasma TV and also especially CRT TV, execute yourself a favor and also get a good, mid-range, 32-inch LCD TV.

How to strength TV in the Off-The-Grid Situations?

There are number of power sources that are provided for powering TVs in assorted off-the-grid situations, like power outage and other emergencies, but also when camping, fishing, hunting, or merely being much away indigenous the nearest wall surface power socket.

These power sources encompass power generators, power inverters linked with deep bike batteries, and power stations.

Actual power demands do differ significantly in between TV sizes and technologies, however in bespeak to keep things as straightforward as feasible and to cover as many cases are possible, we will assume the our hypothetical TV collection requires 100 watts
120 volts

Portable Inverter Generators are typically used to power not just TVs, but many other family appliances.

Small, portable inverter generators function Running watt in the 1000 - 2000 watts selection and beginning Watts in the 1300 - 2500 (or more) watt range.

100 watts TV is a small load because that practically all of these devices - since most little power generators space able to operate at the very least 6-7 hours
120 volts) pack may be powered 10-12, possibly even more hours.

Exact runtime can be uncovered in the generator"s Owner" hands-on or by testing.

Note: once picking increase a an ideal power generator, be certain that noise levels space as low together possible, that THD (Total Harmonic Distortions) are below 3% (preferably under 1.5%) and also that the unit is provided only outside due to the fumes being released!

Power Inverter linked with the Deep cycle Battery: while power generators use fuel to produce the energy, strength inverters use chemical power stored in the battery (or batteries) and convert that into an ideal AC 120V power.

Runtime the such device is usually much shorter than the runtime of the strength generators top top a single full fuel tank, yet the battery may be recharged even using solar panels and also wind turbines.

Hypothetical 100W TV may be easily powered making use of 300-500 watts pure sine tide inverter.

Assuming 85% inverter efficiency, the battery have to be maybe to administer at least ~120 watt of strength - for the battery with the in the name of voltage that 12 volts, the is ~10 Amps the power.

Runtime the such system depends top top the battery size (capacity), the condition, and its chemistry.

For example:

- Mighty Max ML75-12 75Ah 12V SLA AGM Battery: the can provide 150 watt for 5 hours, through the voltage no dropping listed below 10.8 volts,

Note: power Inverters might be offered indoors, but if you space using lead-acid batteries, save the batteries in a well-ventilated area.

Portable power Stations function internal lithium-ion batteries merged with inverter electronic devices to carry out power for various appliances.

Most portable strength stations might easily administer 100 watt of power, however runtime depends on the dimension of the internal battery and the effectiveness of the integrated inverter.

Just favor "ordinary" deep bicycle batteries, the strength stations might be recharged using solar panels or wind turbines, with no dependency on fossil fuels.

For example, Jackery explorer 1000 Portable Power terminal (Amazon link, opens in the new window) is maybe to store ~1000 Wh of energy and also with the 85% efficiency, that is may be to strength 100W TV for ~8.5 hours.

Such strength stations attribute batteries with an extremely low self-discharge rate and are frequently used for camping and also in emergencies - and also they can be conveniently recharged using solar panels throughout the day.

Long Story Short: TV Amps and also Watts vary depending upon the TV size, type, and also the way TV is being used. Out hypothetical 32-inch TV is actually an extremely inefficient when merged with 32-inch LED TV, but since there are various other TV size and types out there, it is vital to usage a somewhat larger value.

If you have actually the should operate a TV in off-the-grid situations, feel totally free to choose between using strength generators, strength inverters an unified with deep cycle batteries, and/or power stations - and also choose follow to your own needs and requirements.
