When getting started with electric camping, you’ll come across lots of different terms like watts, kilowatt-hours, output, capacity and more. But what the heck do these terms mean? And how can you find the right portable charger for your setup and needs? We’re breaking it down in a simple and easy-to-understand way so you can choose the best power solution for your camping adventures.
What Are Watts (W)?
Watts measure the power consumption of a device. Think of it as the strength or power of your device at any given moment. Here’s a simple way to understand it:
- Definition: Watts tell you how much energy a device uses per second. Higher wattage means the device uses more power.
- Example: A 60-watt light bulb uses 60 watts of power every second it’s on.
Knowing the wattage of your devices helps you determine if your power station can handle them. If a device needs more watts than the power station can provide, it won’t work properly.
What Are Watt-Hours (Wh)?
Watt-hours are a way to measure energy use over time. Think of it like this:
- If you use a 1-watt light bulb for 1 hour, that’s 1 watt-hour (Wh).
- If you use a 10-watt light bulb for 1 hour, that’s 10 watt-hours (Wh).
- If you use a 10-watt light bulb for 2 hours, that’s 20 watt-hours (Wh).
What Are Kilowatt-Hours (kWh)?
Kilowatt-hours are just a bigger unit of energy. It’s like measuring distance in kilometres instead of metres.
- Basically, 1 kilowatt-hour (kWh) equals 1,000 watt-hours (Wh).
- So, if you use 1,000 watts for 1 hour, that’s 1 kWh.
How to Calculate Watt-Hours (Wh)
Here’s how to figure out how many watt-hours you’re using:
- Step 1: Look at the power rating of your device (in watts).
- Step 2: Multiply the watts by the number of hours you use the device.
Example: A 100-watt microwave used for 2 hours:→ 100 watts × 2 hours = 200 watt-hours (Wh)
Understanding Capacity (Watt Hours) Vs Output (Watts)
When choosing a portable power station, it’s important to understand two key terms: capacity (watt-hours) and output (watts).
Capacity (Watt-Hours, Wh)
- What It Is: Think of watt-hours as the size of the power station’s battery. It tells you how much energy the battery can store.
- Why It Matters: A higher capacity means the power station can run your devices for a longer time.
- Example: If a portable power station has a capacity of 1000 Wh, it can power a 100-watt device for 10 hours (1000 Wh ÷ 100 watts = 10 hours).
Output (Watts, W)
- What It Is: Watts measure the amount of power the station can supply at one time. It tells you how powerful the power station is.
- Why It Matters: A higher output means the power station can handle more powerful devices.
- Example: If a power station has an output of 1000 watts, it can run devices that need up to 1000 watts of power.
Combining Capacity and Output
Running Time: To find out how long a power station can run a device, divide the capacity (Wh) by the device’s power consumption (W).
Example: A 1000 Wh power station can run a 500-watt microwave for 2 hours (1000 Wh ÷ 500 W = 2 hours).
Device Compatibility: To know if a power station can run a specific device, check the device’s wattage and compare it to the power station’s output.
Example: A hairdryer that uses 1500 watts can’t be used with a power station that has an 800-watt output.
How Many Watts Do Common Appliances Use?
Here’s a handy table to give you an idea of the average wattage for common appliances you might want to take with you eclectic camping.
Example: Using Appliances with EcoFlow’s RIVER 2 Pro Portable Power StationLet’s take a look at EcoFlow’s RIVER 2 Pro and how it would work with some common equipment you might bring on your electric camping adventure.
Details: The RIVER 2 Pro has a capacity of 768 watt-hours (Wh) and can output up to 800 watts.
Summary:
- iPhone: You can charge your iPhone for about 153.6 hours.
- Microwave: You can use an 800-watt microwave for approximately 57 minutes. Higher wattage microwaves (over 800 watts) are not compatible.
- Induction Cooktop: Not compatible as it exceeds the 800W output limit.
- Bluetooth Speaker: You can use it for about 38.4 hours.
- Electric Kettle: Not compatible as it exceeds the 800W output limit.
- Mini Fridge: You can run it for about 7.68 hours.
- Hairdryer: Not compatible as it exceeds the 800W output limit.
- Laptop: You can run it for about 7.68 hours.
- Coffee Maker: Compatible if it’s 800 watts or less, and you can use it for about 1.28 hours.
Portable Power Stations for High-Wattage Appliances
To run high-wattage appliances like a hairdryer or an induction cooktop, you’ll need a portable power station with a higher output capacity. Here are some options and what to look for:
Look For:
- High Wattage Output: Make the power station can handle at least 1500-2000.
- Large Battery Capacity: A larger battery capacity (measured in watt-hours, Wh) means longer run times.

Important Tips for Choosing a Portable Power Station
- Check Appliance Wattage: Always check the wattage requirements of your appliances before purchasing a power station.
- Consider Battery Life: Higher battery capacity (Wh) means longer run times, so choose based on your expected usage.
- Multiple Outlets: Look for a power station with multiple AC outlets if you plan to run more than one high-wattage appliance simultaneously.
- Portability vs. Power: Higher capacity and output often mean a heavier and less portable unit. Balance your need for power with how easy it is to transport.
FAQs
What happens if your appliance has a higher watt than the output of the portable power station?
If your appliance requires more watts than your portable power station can output, it won’t work properly. Here are a few things that might happen:
- The appliance may not power on at all.
- The portable power station might go into overload protection mode to prevent damage. This means it will automatically shut down.
- The appliance might start but then cut out repeatedly, as the power station can’t provide a consistent supply.
- Some appliances might operate but not at their full capacity, leading to inefficiency or potential damage over time.
How do I calculate how long my power station will run my devices?
Divide the power station’s capacity (Wh) by the device’s power consumption (W). For example, a 1000 Wh power station can run a 50-watt device for 20 hours (1000 Wh ÷ 50 W = 20 hours).
Are solar panels a good option for recharging my power station?
Yes, solar panels are a great, eco-friendly option to recharge your power station, especially when you’re camping off-grid. Just make sure the solar panel is compatible with your power station.
What’s the difference between a portable power station and a generator?
A portable power station is a large battery that stores and supplies power silently and cleanly. Traditional generators run on fuel (like petrol or propane), can be noisy, and produce emissions. However, brands like EcoFlow offer electric generators that work with portable power stations, providing a more eco-friendly and easy-to-use alternative to traditional fuel-powered generators.
How do I know if my device is compatible with my power station?
Check the device’s wattage and compare it to the power station’s output capacity. Make sure the device’s wattage doesn’t exceed the power station’s maximum output.
Is electric camping gear weather-resistant?
Most electric camping gear is designed to withstand outdoor conditions, but it’s always best to check the specific product’s specifications for water and dust resistance.
