📝 Guide: How to Size Your Power Station — Match Watt-Hours to Your Devices in 2 Steps
Buying a portable power station but not sure what size you need? Choosing the right watt-hour (Wh) capacity can be confusing — but it doesn’t have to be. In just two simple steps, you can calculate the right size power station for your apartment, camping trip, or backup plan.
🔋 Step 1: Find Your Device Power Ratings
Every device has a power rating, usually shown in watts (W).
Phone charger → 10W
Laptop → 60W
Wi-Fi router → 15W
Mini fridge → 100W
👉 Pro Tip: If your device lists volts (V) and amps (A), multiply them:Watts = Volts × Amps
⚡ Step 2: Calculate Watt-Hours (Wh) Needed
Use this formula:Watt-Hours = Device Watts × Hours of Use
Example:
Laptop (60W × 4 hours) = 240Wh
Wi-Fi Router (15W × 6 hours) = 90Wh
Total = 330Wh
So, you’d need at least a 300–500Wh power station for those two devices.
📊 Quick Size Guide
<300Wh → Small gadgets, phones, tablets, cameras.
300–700Wh → Laptops, routers, fans, lights.
700–1500Wh → Mini fridge, CPAP, TV, multiple devices.
1500Wh+ → Fridges, power tools, multi-day outages.
🏆 Recommended Models by Size
Small (200–300Wh) → EcoFlow RIVER 2, Jackery Explorer 240
Medium (500–700Wh) → Jackery Explorer 500, BLUETTI EB55
Large (1000–1500Wh) → EcoFlow DELTA 2, Jackery Explorer 1000
Extra Large (1500Wh+) → BLUETTI AC200P, EcoFlow DELTA Pro
✅ Conclusion
Sizing your power station doesn’t need to be complicated. By checking your devices’ wattage and multiplying by hours of use, you can confidently pick the right model for your needs — without overspending or ending up with too little power.
