Key Takeaways
- Portable power stations are rechargeable, battery-powered devices that provide electricity on the go.
- They are quieter than gas generators, emissions-free during use and safe for indoor use when operated properly.
- Most units include AC, USB and DC outlets to power a variety of devices and small appliances.
- You can recharge them using a wall outlet, solar panels or a vehicle’s 12-volt outlet.
- Common uses include emergency backup, camping, travel and powering tools or devices at home.
- Capacity (measured in watt-hours) determines how long a unit can run your devices.
- Output options and wattage ratings are important for compatibility with your electronics.
- Portability, size and durability should match how and where you plan to use the unit.
- To choose the right size, calculate total wattage and usage time, then select a unit with slightly higher capacity.
What Is a Portable Power Station?
A portable power station — sometimes called a battery generator — is a compact device with a built-in rechargeable battery that supplies electrical power on demand.
Unlike traditional gas generators, portable power stations:
- Operate quietly (though not always completely silently)
- Produce no exhaust or emissions during use
- Can be used safely indoors when operated correctly
Most models include multiple output options, such as:
- AC outlets for household devices
- USB ports for phones and small electronics
- DC ports for specialty or automotive devices
You can use them to charge or power a wide range of electronics and small appliances.
How Does a Portable Power Station Work?
A portable power station stores energy in an internal battery and delivers that energy to connected devices when needed.
Charging the Battery
The unit is charged using an external power source, such as:
- A standard wall outlet (AC power)
- Compatible solar panels
- A vehicle’s 12-volt outlet
Energy Storage
The battery stores energy measured in watt-hours (Wh). This rating indicates how much energy the unit can hold and helps estimate runtime.
Powering Devices
When you plug in a device, the station either:
- Delivers DC power directly
- Uses an internal inverter to convert DC power into AC power for household devices
What Can a Portable Power Station Do?
Portable power stations provide flexible power for a variety of situations.
Emergency Backup
During power outages, power stations can keep essential devices running, such as:
- Phones and laptops
- Wi-Fi routers
- Small appliances, depending on capacity
Travel and Outdoor Use
Great for camping, tailgating or road trips, portable power stations can:
- Charge cameras, laptops and phones
- Power lights or small cooking devices
Home and DIY Use
At home, power stations can:
- Provide temporary power in garages, sheds or backyards
- Run tools or electronics where outlets aren’t available
Things to Consider Before Buying a Portable Power Station
Here are the most important points to think about when shopping for a power station.
Capacity (Watt-Hours)
- Capacity determines how long a unit can run your devices.
- Example: A 60W laptop used for 5 hours requires about 300Wh.
- In practice, plan for extra capacity to account for energy loss.
Output and Ports
Look for the right mix of ports for your needs:
- AC outlets (pay attention to wattage rating)
- USB-A and USB-C ports (including fast-charging options)
- DC outputs
Recharge Options
Most units support multiple charging methods:
- AC Outlet: Fastest and most reliable for full charging
- Solar Panels: Useful for off-grid use; charging speed depends on sunlight and panel wattage
- Vehicle (12V) Charging: Convenient on the go but typically requires a longer charging time
Portability
Consider:
- Weight
- Size
- Handle or wheel design
Smaller units are easier to carry, while larger units offer more power but less mobility.
Durability
If you plan to use a portable power station outdoors or on job sites:
- Look for rugged construction
- Check for dust or water resistance ratings
What Size Portable Power Station Do You Need?
Choosing the right size depends on your power needs:
- List the devices you want to power.
- Note each device’s wattage.
- Estimate how long you’ll use each device.
- Multiply wattage by hours to calculate watt-hours.
Example:
If your devices total 150W and you plan to run them for 4 hours: 150W × 4 hours = 600Wh
Choose a unit slightly larger than your estimate to account for efficiency losses and future needs.

Portable Power Stations: FAQs
Below are answers to some of the most common questions Lowe’s customers have about portable power stations to help you make an informed decision.
What Can a Portable Power Station Run?
A portable power station can run small appliances and electronics such as smartphones, laptops, Wi-Fi routers, lights and some kitchen devices. Larger appliances like refrigerators or power tools can also run on higher-capacity models with sufficient wattage output.
How Long Does a Portable Power Station Last?
The runtime of a portable power station depends on its battery capacity (measured in watt-hours) and the power consumption of connected devices. For example, a 500Wh unit can power a 100W device for about 5 hours, though actual performance may vary due to energy loss and efficiency.
How Do You Choose the Right Portable Power Station Size?
To choose the right size portable power station, calculate the total wattage of the devices you plan to use and multiply it by the number of hours you’ll need power. Select a unit with a higher watt-hour capacity than your estimate to ensure reliable performance and account for efficiency losses.
