Introduction

If you’re new to portable power stations, terms like Wh and W can be confusing.

This guide explains them in simple terms.

---

What Is Battery Capacity (Wh)?

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

👉 Think of it as fuel in a tank.

---

What Is Output Power (W)?

Watts (W) measure how much power can be delivered at once.

👉 Think of it as engine strength.

---

Why Both Matter

• High Wh → longer runtime
• High W → supports powerful devices

---

Example

• 500Wh + 300W → small devices
• 2000Wh + 2000W → appliances

---

Common Mistakes

• Choosing based on capacity only
• Ignoring peak/surge power

---

Conclusion

Understanding these basics helps you choose the right power solution with confidence.
