🔌 How to Choose the Right Size Portable Power Station
With so many options out there, finding the right portable power station can feel overwhelming — especially if you’re not sure how much power you actually need. We’re 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 you’ll never use — or worse, coming up short when it matters most.
✅ Step 1: Make a List of What You’ll Power
Start by listing all the devices and appliances you want to run — whether it’s 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.
⚡ 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 — then add 20% extra to account for startup surges from things like compressors, pumps, or motors.
📊 Common Device Wattage Chart
| Device | Typical Wattage |
|---|---|
| Smartphone | 2–6W |
| Tablet | 10–20W |
| Laptop | 30–200W |
| LED Light Bulb | 5–15W |
| Router/Modem | 10–30W |
| Mini Fridge | 40–100W |
| Full-Size Refrigerator | 150–400W (500–600W surge) |
| Microwave Oven | 800–1500W |
| Electric Kettle | 1000–1500W |
| TV (32"–55" LED) | 30–120W |
| CPAP Machine | 30–60W |
| Coffee Maker | 600–1200W |
| Portable Fan | 30–70W |
| Small Space Heater | 750–1500W |
| Portable A/C Unit | 1000–1500W (up to 2000W surge) |
| Electric Grill or Skillet | 1000–1800W |
| Power Tool (Drill/Saw) | 600–1500W |
| Washer/Dryer Combo | 1200–2000W |
| Electric Blanket | 200–400W |
| Inflation Pump or Compressor | 200–1000W |
Pro Tip: Always plan for the item with the highest startup surge — that spike can trip your system if the output wattage isn’t high enough, even if your capacity is.
🔋 Step 3: Match Power Needs to Battery Capacity
Power station capacity is measured in watt-hours (Wh) — that tells you how much total energy the unit can store. To estimate runtime, divide the unit’s Wh rating by the watts your devices consume. For example, a 1000Wh unit running a 100W mini fridge will last about 10 hours.
📦 Capacity Guide + EcoFlow Recommendations
| Station Size | Capacity (Wh) | Example Uses | Recommended EcoFlow Model |
|---|---|---|---|
| Small | 100–500Wh | Phones, tablets, LED lights, Wi-Fi routers | EcoFlow RIVER 2 or RIVER 2 Max |
| Medium | 500–1500Wh | Laptops, TVs, CPAPs, mini fridge, coffee makers | EcoFlow DELTA 2 or DELTA 2 Max |
| Large | 1500–3000Wh | 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 unit’s output wattage is also high enough to power your most demanding device.
🎒 Step 4: Consider Portability and Features
Depending on where and how you’ll use it, different features might matter more. Here’s 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
📊 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
