What Can a Portable Solar Power Station Run?

A portable solar power station, often called a “solar generator,” is essentially a large rechargeable battery with an inverter that converts stored electricity into usable AC or DC power for your devices.
The big question most buyers ask is: “What can it actually run?”

The answer depends on two main factors:

1. Capacity (Watt-Hours – Wh)

  • Watt-hours (Wh) measure how much total energy is stored.

  • The higher the Wh, the longer you can power devices.

  • Example: A 2000Wh station can run a 100W device for about 20 hours (minus efficiency losses).

2. Output Power (Watts – W)

  • Watts (W) measure how much power a device needs at any given moment.

  • The station must have an inverter that can handle the device’s continuous power draw and surge (startup) power.

Everyday Devices You Can Run

Here’s what different size portable power stations can handle:

Device / Appliance Typical Wattage 500Wh Station 1000Wh Station 2000Wh Station 3600Wh Station
Smartphone 5W ✅ 90+ charges ✅ 180+ charges ✅ 350+ charges ✅ 600+ charges
Laptop 60W ✅ 7 hrs ✅ 14 hrs ✅ 28 hrs ✅ 50+ hrs
LED Light Bulb 10W ✅ 40 hrs ✅ 80 hrs ✅ 160 hrs ✅ 300+ hrs
Wi-Fi Router 15W ✅ 26 hrs ✅ 53 hrs ✅ 106 hrs ✅ 200+ hrs
Portable Fridge 60W ❌ short use ✅ 14 hrs ✅ 28 hrs ✅ 50+ hrs
Full-Size Refrigerator 150W ❌ ❌ ✅ 12 hrs ✅ 24+ hrs
CPAP Machine 40W ✅ 10 hrs ✅ 25 hrs ✅ 45 hrs ✅ 90+ hrs
TV (42”) 100W ❌ ✅ 8 hrs ✅ 18 hrs ✅ 35+ hrs
Power Tools (Circular Saw) 1200W ❌ ❌ short use ✅ 1.5 hrs ✅ 3+ hrs
Window AC Unit 1000W ❌ ❌ ✅ 1.8 hrs ✅ 3.5 hrs

✅ = Suitable use case
❌ = Not recommended for long-term use

Best Uses by Capacity Size

  • 500–1000Wh: Phones, laptops, cameras, LED lights, fans, routers — great for camping.

  • 1000–2000Wh: Refrigerators, TVs, small appliances, CPAP — perfect for short outages.

  • 2000–3600Wh+: High-demand appliances, home backup, RVs, power tools — ideal for long outages or off-grid setups.

Limitations

  • Portable solar stations aren’t ideal for large heating/cooling systems, electric stoves, or water heaters without high capacity (3600Wh+).

  • Runtime decreases with high-power devices — a 1500W space heater will drain even a large unit in under 2 hours.

Pro Tip: Extend Runtime with Solar

Pairing your station with solar panels allows you to recharge during the day, extending your power indefinitely — perfect for off-grid living or extended emergencies.

Bottom Line:
A portable solar power station can run everything from a smartphone to a full-size fridge, depending on its capacity and output.
For emergency home backup or off-grid living, look for 2000Wh or higher models for maximum versatility.
