If you\u2019ve ever sat through a blackout mid-movie, spent a camping trip without enough juice for the TV (and the post-game show you\u2019ve been looking forward to all week), or panicked when your client brought a 55-inch screen to a pop-up event we set up and we weren\u2019t sure if our power station would cut it, you\u2019ve probably asked the same question I get every single day: \u201cWhat size of TV can a portable power station actually power?\u201d Portable Power Station<\/a><\/p>\n

<\/p>\n

I\u2019m the co-founder of a portable power station company, and over the past 7 years, I\u2019ve fielded this question from campers, tailgaters, event planners, and even folks stuck through grid outages in neighborhoods where the power company takes twice as long to fix a line as they say they will. The short answer isn\u2019t as simple as \u201ca 50-inch TV\u201d or \u201ca 75-inch TV\u201d\u2014it\u2019s way more tied to two things most people don\u2019t stop to break down first: how much power your TV actually uses, and how much usable power your portable power station has. Let me walk you through it, since I\u2019ve seen too many people buy a power station that\u2019s too small (or too big, wasting money they could\u2019ve spent on extra batteries for their portable speaker instead) because they didn\u2019t understand the basics.<\/p>\n

First, let\u2019s talk about TV power use\u2014this is the part most websites will tell you wrong, because they\u2019ll just pull a random \u201caverage\u201d number and call it a day, but TVs don\u2019t all use the same amount of power. Think about it: a tiny 24-inch kitchen TV is going to use way less than a 85-inch 4K smart TV that has 10 speakers built in, a backlight that\u2019s way brighter than it needs to be, and is running 10 background apps while you watch. Even the same size TV can vary by brand and model\u2014we\u2019ve tested this with every major TV line over the past 5 years because we needed accurate numbers for our own customer guides.<\/p>\n

Let\u2019s break this down by screen size, and I\u2019m going to use real numbers we collected from testing: a 24-inch LED TV uses about 30-50 watts when it\u2019s on and at normal brightness. A 32-inch is 40-70 watts, a 43-inch runs 60-100 watts, 50-inch is 80-120 watts, 55-inch is 100-150 watts, 65-inch is 120-200 watts, 75-inch is 180-280 watts, and 85-inch? That big boy clocks in at 250-400 watts, depending on if it\u2019s LED, QLED, or OLED. OLED TVs use a little less power than QLED when they\u2019re showing dark screens, but way more when they\u2019re showing bright, white images\u2014so don\u2019t just go by the label on the box, which usually only gives a maximum wattage, not the average you\u2019ll actually use while watching.<\/p>\n

Now, the next part: portable power station capacity. This is where so many people get confused, because power stations list their capacity in watt-hours (Wh), not watts, and not all of that is usable power. Let\u2019s say you have a 1000Wh power station\u2014you might think that means it can power a 100-watt TV for 10 hours, right? That\u2019s not how it works. First, lithium-ion batteries (the kind all good portable power stations use) can\u2019t discharge 100% of their power without damaging the battery long-term. Most quality power stations\u2014including the ones we sell\u2014have a \u201cdepth of discharge\u201d (DoD) of around 80%, meaning you can only safely use 80% of the listed capacity. So that 1000Wh unit? That\u2019s 800Wh of actual usable power for your devices.<\/p>\n

Then there\u2019s the inverter efficiency. The inverter is the part of the power station that turns the DC power from the battery into AC power that your TV uses. Cheaper power stations have inverters that are only 80-85% efficient, meaning 15-20% of the power is lost as heat when it\u2019s converted. Good, high-quality inverters are 90-95% efficient\u2014so 5-10% lost. For our power stations, we use 93% efficient inverters, so let\u2019s do the math for that 1000Wh unit: 1000Wh x 0.8 (DoD) x 0.93 (inverter efficiency) = ~744Wh of actual power you can use on things like your TV.<\/p>\n

Now, let\u2019s put that together for the TV example. Let\u2019s say you have a 55-inch TV that uses 120 watts on average. How long will that 1000Wh power station run it? Take the usable power (744Wh) divided by the TV\u2019s wattage (120W) = 6.2 hours. That\u2019s more than enough for a full movie, a post-game show, and a little extra to charge your phone while you\u2019re at a tailgate, right?<\/p>\n

But wait\u2014what if you have a bigger TV, say a 75-inch that uses 250 watts on average. Let\u2019s plug that same 1000Wh unit into the math: 744Wh divided by 250W = ~3 hours. That\u2019s enough for two hours of your favorite show, but not a full 3-hour movie, and if you try to use other things at the same time (like a portable cooler, or your laptop), that time drops even more. That\u2019s why we get so many emails from customers who bought a cheap 1000Wh power station online, tried to run their 75-inch TV, and said it died way too fast. They didn\u2019t account for DoD, inverter loss, and the actual wattage of their big TV\u2014they just saw \u201c1000Wh\u201d and thought it could power anything.<\/p>\n

Let\u2019s go through common scenarios, since that\u2019s what most people are here for. If you\u2019re a weekend camper who wants to watch a movie after dark with your family, what size power station do you need? If you have a 50-inch or smaller TV, a 500Wh power station will work. Let\u2019s test that: 500Wh x 0.8 DoD x 0.93 inverter = 372Wh usable. A 50-inch TV uses 100 watts average, so 372 \/ 100 = ~3.7 hours. That\u2019s perfect for a 2-hour movie with an hour left to spare. If you have a 55 or 65-inch TV, step up to a 1000Wh power station, which gives you 6 hours with a 55-inch, or 3 hours with a 65-inch.<\/p>\n

Now, what if you\u2019re hosting a tailgate with friends, and you want a 75-inch TV for the whole game? Most NFL games are 3 hours, college games can be 3.5 or 4 hours, so you need enough power to cover that, plus maybe a little extra. A 75-inch TV uses 250 watts average, so over a 4-hour game, that\u2019s 1000Wh of power just for the TV. You\u2019d want at least a 1500Wh power station here\u20141500Wh x 0.8 DoD x 0.93 inverter = ~1116Wh usable, which is just enough for 4 hours (250W x 4 = 1000Wh). If you want to add a portable grill fan, a speaker, and charge a few phones, go up to 2000Wh, which gives you ~1488Wh usable\u2014way more than enough for a full game plus extra.<\/p>\n

What about grid outages? If you\u2019re keeping a TV on during a blackout, you might not need it on 24\/7, but you want enough power to watch the news, a show, and maybe a movie over the course of a few days. If you have a 65-inch TV, that\u2019s 200 watts average. Let\u2019s say you use it 2 hours a day: 400Wh per day. A 2000Wh power station (the size most people get for home backup) would give you ~1488Wh usable, so that\u2019s almost 4 days of TV time. Add a few LED bulbs, a fridge, and some phone chargers, and a 2000Wh is still manageable\u2014just don\u2019t run your TV 8 hours a day, obviously.<\/p>\n

Wait, what about OLED vs. QLED vs. LED? I mentioned this earlier, and it\u2019s a common question. OLED TVs use less power when showing dark content, but when they\u2019re showing bright, white scenes (like a soccer field, or a news broadcast with a white background), they use almost the same as QLED or LED. We tested a 65-inch OLED vs. a 65-inch QLED side by side: when watching a dark movie, the OLED used 130 watts, the QLED used 150 watts. When watching a bright football game, the OLED used 190 watts, the QLED used 185 watts. So the difference is small for average use, but if you\u2019re watching content with a lot of dark scenes, OLED can save you a little power, which adds a fraction more runtime on your power station.<\/p>\n

Now, what are the mistakes we see people make all the time? First, buying a power station that only lists \u201cmax\u201d inverter capacity, not continuous capacity. A lot of cheap power stations will say they have a 2000W inverter, but that\u2019s only a 10-second surge\u2014your TV only needs about 100-200 watts to start, and then runs on a steady 80-150 watts. If a power station has a 1000W continuous inverter, that means it can power things that need up to 1000 watts nonstop, which is what you need for a TV. A lot of folks will buy a power station with a big surge rating but small continuous rating, and wonder why their TV won\u2019t turn on\u2014because the inverter can\u2019t handle the steady load. That\u2019s why all our power stations list both surge and continuous inverter rating, front and center, so you don\u2019t make that mistake.<\/p>\n

Another mistake: not accounting for other devices. If you\u2019re powering your TV plus a soundbar, plus a streaming stick, plus a portable cooler, all that adds to the total wattage. A soundbar uses 20-50 watts, a streaming stick uses 5-10 watts, so add 60 watts to your total if you have those, which means your power station will run the TV a little less. We always tell customers to add 10-20% to the TV\u2019s wattage to cover extra accessories, just to be safe.<\/p>\n

What about TVs that use 12V vs. 110V\/220V power? Most modern TVs use standard AC power (110V in North America, 220V in Europe, AU, etc.), which is what all portable power stations output. Older TVs, especially RV or boat TVs, might be 12V DC, which you can plug directly into a car port on the power station\u2014no inverter needed, so you lose zero power to conversion, which gives you a little extra runtime. That\u2019s a good tip for anyone with an older TV, or a TV in an RV: check if it\u2019s 12V first, that\u2019ll save you some wattage.<\/p>\n

Let\u2019s test a real customer example, because I had one last month that shows how this all works. A guy reached out to us, said he had a 75-inch TV and wanted to take it camping, and had a 1000Wh power station he bought from a big-box store online. He said it only ran his TV for 1.5 hours, which was way less than he expected. We walked him through the numbers: his TV is a 75-inch QLED, which we tested at 270 watts average when watching a bright movie (higher than our earlier average, because he likes his screen at full brightness, which is common). The power station he bought had a 75% DoD (cheaper batteries) and a 82% efficient inverter, so usable power was 1000Wh x 0.75 x 0.82 = 615Wh. 615 divided by 270 watts = ~2.2 hours, which is close to what he got, but he was also running a portable speaker that uses 30 watts, so total wattage was 300 watts, so 615 \/ 300 = ~2 hours, and with inefficiency from the inverter, that dropped to 1.5. We suggested he upgrade to our 1500Wh power station, which has 80% DoD and 93% inverter efficiency, so usable power is 1500 x 0.8 x 0.93 = 1116Wh. Even with the TV at 270 watts and speaker at 30, that\u2019s 1116 \/ 300 = ~3.7 hours, plus he has extra power for charging his phone and a portable cooler. He bought it, and sent a message a week later saying he watched a full 3.5-hour movie with his family and still had power left over\u2014perfect.<\/p>\n

Now, what about the future? A lot of newer smart TVs use even less power, thanks to better LED and OLED technology. We tested a new 2024 65-inch 4K smart TV last month that only uses 110 watts average, compared to 150 watts for a 2020 model, so that\u2019s a 27% drop in power use. That means a power station will run newer TVs longer, so if you\u2019re buying a new TV, keep an eye on the wattage listed for the specific model, not just the average for the size.<\/p>\n

At the end of the day, there\u2019s no one-size-fits-all answer to \u201cwhat size TV can a portable power station power,\u201d but the formula is simple: take the usable power of your portable power station (watt-hours x DoD x inverter efficiency), divide that by the total average wattage of your TV plus any accessories you\u2019ll run with it, and that gives you the runtime. We\u2019ve seen everything from tiny 24-inch TVs running on 100Wh power stations for 10 hours (great for kids\u2019 movies at camp) to 85-inch TVs running on 3000Wh power stations for 5 hours (perfect for big outdoor events).<\/p>\n

<\/p>\n
