๐ How to Choose the Right Size Portable Power Station
With so many options out there, finding the right portable power station can feel overwhelming โ especially if youโre not sure how much power you actually need. Weโre here to make it simple. This guide breaks down the process into five quick steps so you can size your unit confidently and avoid paying for power youโll never use โ or worse, coming up short when it matters most.
โ Step 1: Make a List of What Youโll Power
Start by listing all the devices and appliances you want to run โ whether itโs just the basics like phones and tablets, or larger gear like refrigerators and power tools. This gives you a full picture of your energy needs and helps avoid surprises later.
โก Step 2: Add Up Your Total Wattage
Every device draws a certain amount of power. You can usually find the wattage on a label, manual, or by using an online calculator. Add up the wattage of everything you'll run at the same time โ then add 20% extra to account for startup surges from things like compressors, pumps, or motors.
๐ Common Device Wattage Chart
Device | Typical Wattage |
---|---|
Smartphone | 2โ6W |
Tablet | 10โ20W |
Laptop | 30โ200W |
LED Light Bulb | 5โ15W |
Router/Modem | 10โ30W |
Mini Fridge | 40โ100W |
Full-Size Refrigerator | 150โ400W (500โ600W surge) |
Microwave Oven | 800โ1500W |
Electric Kettle | 1000โ1500W |
TV (32"โ55" LED) | 30โ120W |
CPAP Machine | 30โ60W |
Coffee Maker | 600โ1200W |
Portable Fan | 30โ70W |
Small Space Heater | 750โ1500W |
Portable A/C Unit | 1000โ1500W (up to 2000W surge) |
Electric Grill or Skillet | 1000โ1800W |
Power Tool (Drill/Saw) | 600โ1500W |
Washer/Dryer Combo | 1200โ2000W |
Electric Blanket | 200โ400W |
Inflation Pump or Compressor | 200โ1000W |
Pro Tip: Always plan for the item with the highest startup surge โ that spike can trip your system if the output wattage isnโt high enough, even if your capacity is.
๐ Step 3: Match Power Needs to Battery Capacity
Power station capacity is measured in watt-hours (Wh) โ that tells you how much total energy the unit can store. To estimate runtime, divide the unitโs Wh rating by the watts your devices consume. For example, a 1000Wh unit running a 100W mini fridge will last about 10 hours.
๐ฆ Capacity Guide + EcoFlow Recommendations
Station Size | Capacity (Wh) | Example Uses | Recommended EcoFlow Model |
---|---|---|---|
Small | 100โ500Wh | Phones, tablets, LED lights, Wi-Fi routers | EcoFlow RIVER 2 or RIVER 2 Max |
Medium | 500โ1500Wh | Laptops, TVs, CPAPs, mini fridge, coffee makers | EcoFlow DELTA 2 or DELTA 2 Max |
Large | 1500โ3000Wh | Microwaves, power tools, space heaters, portable A/C | EcoFlow DELTA Max or DELTA Pro |
Extra Large | 3000Wh+ | Washer/dryers, large fridges, off-grid cabins, RV life | EcoFlow DELTA Pro Ultra |
Note: Capacity tells you storage, but make sure your unitโs output wattage is also high enough to power your most demanding device.
๐ Step 4: Consider Portability and Features
Depending on where and how youโll use it, different features might matter more. Hereโs what to keep an eye on:
- Multiple AC/USB ports: Charge several devices at once
- Solar input: Recharge in the field with solar panels
- Pass-through charging: Use while recharging
- Quiet fanless design: For sleeping spaces or indoors
- Expandable batteries: Future-proof larger needs
- Wheels or handle: Useful for heavier units
- Pure sine wave inverter: Safe for sensitive tech
๐ Step 5: Compare Models That Fit Your Needs
Once you know what power and features you need, compare your top choices. Look at:
- Output wattage: Can it handle your biggest device?
- Customer reviews: Any reliability concerns?
- Warranty/support: Good coverage = peace of mind
- Charging speed: Especially important if using solar
- Cycle lifespan: 500+ cycles = good longevity
