For a typical one-night camping trip with lights, phones, and a fan, you need about 305Wh of usable power, which is a rated capacity of about 359Wh after conversion losses. That is why a 768Wh station is the comfortable one-night and two-night size for a light camping bundle, a 1,024Wh to 1,056Wh station is the size to look at once you add an electric cooler, and anything beyond three nights without recharging pushes you toward the 2,048Wh class or toward solar. Trip length changes the answer more than device count does, because every extra night multiplies the same daily total.
This calculator is preloaded with a typical one-night camping bundle as three separate rows, one day per charge: LED lights and string lights at 10W for 5 hours (50Wh), phone and tablet charging at 15W for 3 hours (45Wh), and a camping fan at 35W for 6 hours (210Wh). That totals 305Wh per day, with a peak of only 60W if everything runs at once. Change the Days per charge value to 2 or 3 to size a whole weekend or a longer trip without recharging, add an electric cooler, a CPAP, or camera batteries as extra rows, and the calculator totals everything, shows the math, and matches you to the smallest station we link to that covers it. For a mixed load beyond camping, the general Power Station Size Calculator does the same job with a wider set of presets, and our sizing guide explains the formula behind both.
Every figure on this page is a planning estimate built from manufacturer specifications and typical published draw ranges, not a measured result, a hands-on test, or a rating. Real draws vary with settings, temperature, and how full a battery already is. Our complete camping guide covers campground rules, bear-country food storage, and solar setup in depth, and our best portable power station for camping picks compare the camping-focused models in this catalog.
Typical camping loads and what they really draw
Most camping loads are small. The exceptions are anything that cools, heats, or runs all night. Use these planning ranges when you edit the rows above, and check the label or manual for your own gear where you can.
- LED lanterns and string lights: 5 to 15W. At 10W for 5 evening hours, that is 50Wh. String lights left on all night cost more in hours than in watts, so turn them off when you sleep.
- Phone and tablet charging: about 15Wh per full phone charge. The charging row in this calculator uses 15W for 3 hours (45Wh), which covers a few devices topping up in the evening. A nearly full phone sips far less.
- Camping fan: 10 to 35W, depending on size and speed. At 35W for 6 hours, a larger fan uses 210Wh, which is the biggest single item in the preloaded bundle. A small USB fan can use a fraction of that.
- Electric cooler or 12V compressor fridge: 35 to 60W while the compressor runs, cycling on and off. Planned honestly, that is roughly 400 to 700Wh per day, more than every light load on this page combined. Whether you bring one is the single biggest sizing decision on a camping trip, and it is covered in depth in our camping guide.
- Camera and drone batteries: 20 to 60W while charging, about 50 to 100Wh in total for a typical evening of topping up a camera battery and a small drone pack.
- CPAP without a humidifier: 15 to 40W, about 240Wh for an 8-hour night. A heated humidifier can multiply that figure, so CPAP users should size for their own machine and settings first.
- Laptop: 45 to 90W while charging, about 120Wh for 2 hours. Portable speaker: 5 to 15W, about 30Wh for an evening.
Car camping is not backpacking: the weight reality
The stations this calculator can recommend weigh about 17 to 50 pounds, because capacity is heavy: roughly speaking, every 1,000Wh of LiFePO4 capacity weighs 22 to 28 pounds once the inverter and case are included, using manufacturer figures. That range works for car camping, where the station travels in the vehicle and moves a few steps to the tent or picnic table. The 768Wh EcoFlow River 2 Pro at about 17 pounds is a one-person carry over a short distance. The 1,024Wh to 1,070Wh stations at about 24 to 28 pounds are a two-hand carry. The 2,048Wh EcoFlow Delta 2 Max at about 50 pounds is a wagon, a two-person lift, or a station that lives where the vehicle parks.
For backpacking, the honest answer is different: none of the six stations we link to is a backpacking station. If you are carrying everything on your back for miles, a small power bank for phones and lights is the right tool, and a 17-pound station is not, however well it fits the math above. Be honest about the distance from the car to the site before you choose a size, because a station you dread carrying is a station you stop bringing.
Trip length changes the answer more than device count
Adding another phone adds about 15Wh a day. Adding another night adds the whole day again. That is the arithmetic that surprises people: the preloaded bundle is 305Wh for one night, 610Wh for two nights, 915Wh for three nights, and 1,220Wh for four nights, before losses. The device list barely changed. The calendar did all of that.
It also explains why the recommendation jumps so quickly. A station that covers one or two nights with room to spare can fall short on night three, not because it is a bad station, but because usable capacity is fixed while the need keeps multiplying. When the calculator shows no station fitting a longer trip, that is the honest result for the six stations we link to at that number of days per charge. The fixes are to recharge during the trip, usually with solar, to lower the days per charge to match how often you can actually refill, or to trim the biggest daily load, which is usually the fan hours or the electric cooler.
Solar top-up for multi-day trips
Solar changes a multi-day trip from a capacity problem into a daily-balance problem. The planning math is panel watts multiplied by sun hours, multiplied by 0.8 for real-world efficiency. A 200W portable panel in 5 hours of good sun gives about 800Wh per day, which is more than double the 305Wh daily use of the preloaded bundle. A 100W panel in the same sun gives about 400Wh per day, still enough to cover that light bundle day by day. With a daily refill like that, you size the station for one heavy day plus a cloudy-day buffer, instead of for the whole trip at once, and you set the Days per charge value back to 1 or 2 to reflect how often the panels refill it.
Three practical points from our camping guide: check the station solar input limit first, because a panel array larger than the limit wastes its extra capacity; angle and shade matter more than panel size, because one shaded section can cut output sharply; and set panels up in the morning so the station refills while you are away from camp. Solar does not help a trip with no sun hours, so keep the no-solar math above as your fallback when the forecast is poor.
Worked examples
- One night, preloaded bundle: 305Wh. LED lights 50Wh, phone and tablet charging 45Wh, and a camping fan 210Wh total 305Wh per day. Rated capacity needed is about 359Wh. The EcoFlow River 2 Pro at 768Wh is the smallest station we link to that covers it, with usable capacity of about 653Wh, and the EcoFlow Delta 2 is shown with more headroom.
- A weekend, two nights, same bundle, no recharging: 610Wh. Change Days per charge to 2 and the need doubles to 610Wh, a rated capacity of about 718Wh. The River 2 Pro still covers it on usable capacity, with little room for extra loads, which is why adding an electric cooler on a weekend changes the pick.
- A weekend with an electric cooler: about 845Wh per day. Add a cooler at 45W for 12 hours (540Wh) to the 305Wh bundle and one day needs 845Wh, a rated capacity of about 994Wh. That points to the 1,024Wh class, the EcoFlow Delta 2 and BLUETTI Elite 100 V2, for a single day per charge, and it is the comparison our camping picks are built around.
- Four days, preloaded bundle, no recharging: 1,220Wh. Change Days per charge to 4, or test 3 days at 915Wh first, and the need outgrows every station we link to except the 2,048Wh EcoFlow Delta 2 Max. At 3 days the calculator recommends the Delta 2 Max alone. With a 200W solar panel refilling about 800Wh on a good day, a smaller station can run the same four-day trip day by day, because the daily use is only 305Wh.
The six stations this calculator can recommend
Recommendations come only from the same six stations as our main Power Station Size Calculator, with manufacturer specifications, pictured cards, and current check-price links: EcoFlow River 2 Pro (768Wh, 800W output, about 17 lbs), EcoFlow Delta 2 (1,024Wh, 1,800W, about 27 lbs), BLUETTI Elite 100 V2 (1,024Wh, 1,800W, about 25.3 lbs), Anker Solix C1000 (1,056Wh, 1,050W, about 27.9 lbs), Jackery Explorer 1000 v2 (1,070Wh, 1,500W, about 23.8 lbs), and EcoFlow Delta 2 Max (2,048Wh, 2,400W, about 50 lbs). If none of them covers your days, watts, and watt-hours, the calculator says so and shows the biggest station we link to and what it actually covers, instead of stretching a smaller station into a fit.
Mistakes to avoid
- Sizing for one night and camping for four. Set Days per charge to the longest stretch without a reliable refill, not to the first night.
- Forgetting the cooler. An electric cooler at roughly 400 to 700Wh per day outweighs every light, phone, and camera on the trip combined. Add it as its own row.
- Counting phone watts instead of phone hours. Charging draws are small, but a tablet, a speaker, and lights left on all evening add hours. Enter honest hours, not best-case hours.
- Buying capacity you cannot carry. A 50-pound station is right for a vehicle basecamp and wrong for a walk-in site. Match the weight to the carry you will actually do.
- Assuming solar will save an undersized plan every day. Solar output depends on sun, angle, and shade. Keep enough station capacity for a cloudy day, and check the station solar input limit before buying panels.
- Leaving no headroom. Cold nights, an extra fan hour, and a friend charging a phone all eat margin. A recommendation with some spare capacity is more useful at camp than one that fits to the last watt-hour on paper.
Questions and answers
What size power station do I need for camping? For lights, phones, and a fan for one or two nights, a 768Wh station covers the typical 305Wh-per-day bundle in this calculator. Add an electric cooler and plan on the 1,024Wh class for a day at a time, plus solar for longer stays. For three or more nights with no recharging and no solar, the 2,048Wh class is the size that fits in the catalog we link to.
How many watt-hours does a camping fan use overnight? At 35W for 6 hours, 210Wh. At 8 hours, 280Wh. A smaller fan at 10 to 15W can use under 100Wh for the same night, so the fan model and speed setting matter more than most campers expect.
Can I size a whole weekend by changing one setting? Yes. Keep the device rows the same and change Days per charge from 1 to 2 or 3. The calculator multiplies the same daily total by that number of days, which is why a station that fits one night can stop fitting a three-night trip with no recharging.
Do I need solar for a camping power station? Not for one or two nights if the station is sized for the whole stretch. For longer trips, solar is usually the practical answer: a 200W panel in 5 hours of good sun gives about 800Wh per day by the planning math on this page, which covers a light camping bundle day by day. Match the panel to the station solar input limit.
What is the best size power station for car camping with a fridge? Start with the 1,024Wh class for one day per charge once a 12V compressor fridge is in the load, and add 200W or more of solar for multi-day trips. Our best portable power station for camping page compares the models in that class, and the cooler row in this calculator lets you test your own fridge hours.
Why does the calculator sometimes say no station fits? Because at longer days per charge, or with a cooler running many hours, the total need can pass the usable capacity of the largest station we link to, the 2,048Wh EcoFlow Delta 2 Max. Rather than stretch a recommendation, the calculator shows that largest station and what it actually covers, so you can plan daily recharging, solar, fewer days per charge, or smaller loads.
