What to Consider When Buying a Portable Power Station
When you look at these models, you won’t see a definitive “best” option for all circumstances. You aren’t shopping for a portable power station for a hypothetical average person or household; you are shopping for yourself and your unique needs.
Breaking down your requirements will help you choose which portable power station is right for you.
Your Purpose
What do you hope to accomplish with your portable power station? You might focus on convenience and portability if you want to get away from it all and charge small, essential devices during a mostly unplugged escape from the world.
In this case, you don’t need the kind of power to backup your entire home’s electric supply. A high-capacity option could be overkill for off-grid adventures — whereas the RIVER 2 Series should be just right.
If you’re looking primarily for a home electricity backup source, carefully consider how many appliances and systems you want to run simultaneously during a power outage.
The incidence of blackouts can vary widely across the United States, so it’s worth keeping your location in mind when deciding how much power output and storage capacity you need.
Clearly define what you need from your portable power station before making a purchase decision.
Appliance and Device Electricity Consumption
As mentioned above, consider what devices and appliances you want to use. The starting and running wattage needs of your appliances can help you determine what portable power options are available to you.
Don’t wait for a blackout to find out your portable power station can’t start up your fridge.
Add up the running and starting wattages of your essential appliances, then confirm your portable power station can meet or exceed your needs.
Taking a power consumption inventory of the electronics you need to operate will prevent you from wasting time and money on a portable power station that won’t meet your requirements.
Portability
Not all portable power stations are equally portable. Some are compact, designed to pack in a small space, carry with you to a campsite, and stay on the move. But with the DELTA Pro coming in at 99 pounds, you may want to roll it behind you on a campground trail.
If you’re looking solely for home backup, your power output and consumption requirements will outweigh your portability needs.
If you need something to take with you wherever you go, the smaller, lighter portable power stations like the RIVER 2 series and DELTA 2 will likely make more sense.
For permanent off-grid solutions for RVs and tiny houses, EcoFlow’s modular Power Kits are also worth a look.
Electrical Power Output
As a general rule, with portable power stations, the larger and heavier the unit, the more electricity it can store and output — balance portability concerns against capacity. The smaller power stations won’t cut it if you need to power a high-energy appliance like an air conditioner or a large fridge.
On the other hand, if you just want to charge your smartphones and laptops, the DELTA Pro will seriously exceed your requirements.
Starting and Running Watts of Typical Household Appliances
| Appliance | Rated (Running) Watts | Starting Watts |
| Dishwasher | 1300 | 1800 |
| Washing Machine | 1200 | 2300 |
| Refrigerator/Freezer | 700 | 2200 |
| Light Bulb | 60-75 | 0 |
| Microwave | 600-1000 | 0 |
| TV | 500 | 0 |
| Toaster | 900 | 0 |
| Vacuum | 1440 | 2500 |
| Coffee Maker | 1000 | 0 |
| Blender | 300 | 800 |
| Clothing Iron | 1500 | 0 |
| Dryer | 5400 | 7000 |
| Toaster Oven | 1200 | 0 |
| Curling Iron | 1500 | 0 |
| Space Heater | 2000 | 0 |
| Laptop | 50-300 | 0 |
| 20” Box Fan | 200 | 350 |
Of course, you may be looking for a variety of uses. Planning for mostly-unplugged camping and home electric security might require buying a versatile portable power station like the RIVER 2 Pro or DELTA 2 — or buying more than just one model.
Either way, you want to ensure that you have enough electrical output for your anticipated off-grid activities and home backup needs.
Battery Storage Capacity
The starting power of your largest appliance isn’t the only factor in how much power you need. As mentioned above, you need to calculate the total operating electrical consumption of the sum total of appliances you want to run simultaneously. And estimate how long you want to be able to run your devices without recharging the portable power station.
Battery capacity, measured in kilowatt-hours, is the number of watts the power station can deliver multiplied by the number of hours. For example, running a device that requires 200 Wh of electricity consumption for ten hours requires 2 kWh — the same capacity as operating a device that requires 2000 watts for one hour of use.
When in doubt, aim for a storage capacity 20% higher than your expected needs. If you’re only charging a few devices for a short time — such as recharging smartphones on a camping trip — you can get away with much less planning than when you’re preparing a home backup power system for a blackout.
Charging Time and Convenience
The longer it takes to charge a portable power station, the less convenient it becomes. By purchasing a portable power station, you’re already thinking ahead, but the quicker you can recharge between trips or power outages, the more secure your energy supply will be.
The quickest recharge times typically come from plugging into an AC wall outlet. During a blackout, that’s obviously not an option. A portable power station that you can charge with solar panels, using a car adaptor, USB-C or, in some cases, an EV charging station gives you more versatility and more options to respond to whatever power emergency gets thrown at you.
Price and Your Budget
Buying a portable power station can represent a significant investment. But buying the cheapest option that ends up not meeting your needs is more wasteful than purchasing a more expensive option that meets your electricity storage and generation needs.
With so many EcoFlow solutions to choose from, look for an option that fits your budget and fully meets your needs.
You may also find that financing, discounts, or tax credits and incentives can help defray your initial costs. Take the time to accurately assess your use case and PPS options to ensure you make the best investment for your home backup or off-grid power needs.
FAQs
How long a portable power station will operate without recharging depends on how much energy you consume and your battery storage capacity. When it comes to life span, EcoFlow portable power stations can last for thousands of cycles (discharging and recharging the battery). Heavier use will mean a shorter overall chronological life span before battery efficiency starts to diminish. A portable power station that uses LiFePO4 battery chemistry can last ten years or more, with options like the DELTA Pro rated for 6500 cycles before reaching 50% capacity.
The devices or appliances you can run depend on their starting and operating wattage and run times. If your portable power station doesn’t provide enough output wattage to start or run your desired appliances, you’ll need to purchase a larger PPS. The most robust portable power stations can expand to provide enough power to run your entire home. Check the starting and running wattage of the appliances you want to operate and purchase a PPS with sufficient electricity output.
Conclusion
No portable power station is right for everyone — but one of the six options reviewed above is almost certainly right for you. Once you understand your power needs, you can find a portable power station to deliver.
From the compact RIVER 2 series to the immense power of the DELTA series, the EcoFlow line of portable power stations includes options you can take anywhere and options that can get your home and family through an extended blackout.
