Portable power stations have become popular with car campers who want to charge phones, run lights, power a small fridge or even use a CPAP machine at camp. Unlike gas generators, they run quietly and produce no exhaust. But choosing the right size can be confusing.
This guide explains how power stations work, how to estimate your needs and what features to compare. We describe brands and features based on published information, not our own testing. Check current specifications before buying.
What Is a Portable Power Station?
A portable power station is a rechargeable battery pack with built-in outlets, typically including:
- AC outlets for household devices
- USB-A and USB-C ports
- 12V car-style outlets
You can recharge it from a wall outlet, your car or solar panels.
Power Stations vs. Generators
| Factor | Power Station | Gas Generator |
|---|---|---|
| Noise | Quiet | Louder |
| Emissions | None during use | Exhaust, carbon monoxide risk |
| Fuel | Electricity or solar | Gasoline or propane |
| Runtime | Limited by battery | As long as fuel lasts |
| Campground rules | Often allowed | Often restricted |
Never run a gas generator in or near a tent, vehicle or enclosed space due to carbon monoxide risk.
Key Specifications
Capacity (Watt-Hours)
Capacity is measured in watt-hours (Wh). It tells you how much energy the battery stores. A larger number means more total energy.
Output (Watts)
Output, measured in watts (W), is how much power the station can deliver at once. Devices with high wattage, like electric kettles, may exceed what smaller stations can provide.
Surge Power
Some devices draw more power when starting up. Surge ratings tell you how much short-term power the station can handle.
Battery Chemistry
- Lithium iron phosphate (LiFePO4) batteries are often marketed as having longer cycle life.
- Lithium-ion (NMC) batteries are often lighter for the same capacity.
Charging Options
Look at how fast the station charges from AC, car and solar inputs.
Estimating How Much Capacity You Need
- List devices you want to power.
- Find each device’s wattage, usually on a label or in the manual.
- Estimate hours of use per day.
- Multiply watts by hours to get watt-hours per day.
- Add a buffer for inverter losses and real-world variation. Many people add around 15 to 20 percent.
Example Calculation
| Device | Watts | Hours | Wh |
|---|---|---|---|
| Phone charging (x2) | 10 | 2 | 20 |
| LED lantern | 5 | 5 | 25 |
| Small 12V fridge | Varies | Cycles on and off | Check manufacturer |
| Laptop | 50 | 2 | 100 |
This is an illustration, not a measurement. Check your devices’ actual ratings.
Typical Size Ranges
- Small (under about 500Wh): Phones, lights, cameras and small devices for a weekend.
- Medium (about 500 to 1,000Wh): Adds laptops, small fans and some 12V fridges.
- Large (over 1,000Wh): Heavier loads, longer trips or medical devices.
Larger stations are heavier and more expensive.
Popular Brands to Compare
- Jackery: Known for its Explorer line and solar panels.
- EcoFlow: Offers River and Delta series with fast charging options.
- Anker SOLIX: Anker’s power station line.
- Goal Zero: Yeti series, long associated with outdoor power.
- Bluetti: A range of stations and solar panels.
Compare current models on capacity, output, battery chemistry, weight and warranty.
Solar Charging
Solar panels let you recharge at camp. Keep in mind:
- Real solar output is often lower than a panel’s rated wattage due to sun angle, clouds and heat.
- Position panels to face the sun and adjust them during the day.
- Check that the panel connector and voltage are compatible with your station.
Using a Power Station With a CPAP
Many campers use power stations for CPAP machines. Check with your CPAP manufacturer about DC adapters and power requirements, and ask your healthcare provider if you have concerns. Turning off a humidifier may reduce power use, but follow medical guidance.
Safety Tips
- Follow the manufacturer’s instructions for use and storage.
- Keep the station dry and shaded.
- Avoid extreme heat and cold.
- Do not cover vents.
- Do not exceed rated output.
Campground Considerations
Some campgrounds have electrical hookups, which may reduce the need for a power station. Check ahead. See campsite booking tips.
Lighting Alternatives
If you only need light, rechargeable lanterns and headlamps may be enough. See camping lanterns and headlamps.
Matching a Power Station to Your Trip Length
Trip length changes the math. For a single night, a small station may cover phones and lights easily. For a long weekend, you either need more capacity or a way to recharge during the trip. Options include:
- Driving between sites and charging from the car’s 12V outlet
- Solar panels set up at camp during the day
- Campsites with electric hookups, where you can recharge the station overnight
Planning around recharging can be more practical than buying the largest possible station.
Questions to Ask Before Buying
- What devices will you power, and for how many hours per day?
- Do any devices need AC power, or can they run on USB or 12V?
- How heavy a station can you comfortably carry from the car to the site?
- What warranty does the manufacturer offer?
- Does the station support pass-through charging if you want to charge it and devices at once?
Writing your answers down before shopping makes it much easier to compare specification sheets side by side.
Storing a Power Station Between Trips
Many manufacturers recommend storing power stations partially charged in a cool, dry place and topping them up every few months. Check your manual, since recommendations differ by battery type. Before each trip, charge the station fully at home and test it with the devices you plan to bring.
Frequently Asked Questions
What size power station do I need for camping?
Add up the watt-hours your devices use per day, add a buffer and choose a station with enough capacity.
Can a power station run a fridge?
Many can run 12V fridges designed for camping. Check the fridge’s power use and the station’s capacity.
Can I charge a power station with my car?
Most can charge from a 12V car outlet, though it may be slower than AC charging.
Are power stations allowed in campgrounds?
They are generally quieter than generators and often allowed, but check campground rules.
How long does solar charging take?
It depends on panel wattage, sunlight and station capacity. Real output is often below rated wattage.
The Bottom Line
A portable power station gives you quiet, clean power for camping. Estimate your daily watt-hours, compare capacity, output and battery chemistry, and consider solar charging for longer trips. Choose a size that fits your needs without carrying more weight than you need.
