Choosing the right outdoor power supply capacity can feel overwhelming. Whether you're camping, hosting an event, or preparing for emergencies, this guide breaks down recommended wattage for different scenarios—with real-world examples and easy-to-follow calculations.

Understanding Outdoor Power Supply Capacity

Outdoor power supplies (also called portable power stations) store energy in watt-hours (Wh). To determine how many watts you need, consider two factors:

• Peak Power Demand: The maximum wattage your devices require at startup
• Runtime: How long you need to power those devices

Pro Tip: A 500Wh unit can charge a smartphone 50+ times but might struggle with a portable fridge.

Common Use Cases and Recommended Wattage

Scenario	Devices	Recommended Capacity
Weekend Camping	LED lights, phone charger, mini fan	300-500Wh
RV Road Trip	CPAP machine, electric blanket, coffee maker	1,000-2,000Wh
Outdoor Events	Projector, speakers, blender	2,000-3,000Wh
Emergency Backup	Medical devices, refrigerator, router	3,000Wh+

Calculating Your Power Needs in 3 Steps

1. List all devices and their wattage (check labels or manuals)
2. Multiply each device's watts by hours of use
3. Add 20% buffer for safety and efficiency loss

Example: Running a 50W fridge for 24 hours requires 1,200Wh (50 x 24 = 1,200 + 20% = 1,440Wh).

Why Solar Compatibility Matters

Pairing your power station with solar panels? Look for:

• High solar input (200W+ for faster recharging)
• MPPT charge controllers for better efficiency

Did You Know? EK SOLAR's 2000Wh model recharges in 2.5 hours using compatible 400W panels.

Real-World Case Study: Music Festival Power Solution

A client powered 4 stage lights (100W each), 2 speakers (300W), and a mixing board (150W) for 8 hours. Total requirement: (4x100 + 2x300 + 150) x 8 = 6,800Wh. They chose two 3,500Wh units for redundancy.

FAQ: Outdoor Power Supply Basics

Q: Can I use car batteries instead? A: Not recommended—deep-cycle batteries in power stations handle repeated draining better.

Q: How long do these units last? A quality power station lasts 3-5 years with proper maintenance. EK SOLAR offers a 5-year warranty on selected models.

Final Thoughts

Matching your wattage needs to the right power supply ensures reliability where it matters most. Remember to:

• Calculate total energy consumption
• Consider future expansion
• Verify solar compatibility
