What to Look for in a Power Bank (Important)

1. Capacity vs Actual Output

A 20,000mAh power bank doesn’t give full 20,000mAh.
Real usable output is ~60–70% due to conversion loss.

👉 Think of it like this:
20,000mAh ≈ 12,000–14,000mAh real usage

---

2. BIS Certification (Very Important in India)

Always check for BIS certification.
Without it → risk of overheating, battery damage, or even safety hazards.

---

3. Brand Reliability

Cheap unknown brands may:

• Lose capacity quickly
• Overheat
• Fail after 2–3 months

Stick to:

• Xiaomi → safest
• URBN → decent
• pTron → budget performance

---

Final Verdict (Simple)

• Best overall: Xiaomi Power Bank 4i → safest long-term choice
• Best value: pTron Dynamo Sprint → fastest charging for price
• Best for daily carry: URBN Turbo → lighter & compact

If you’re confused:
👉 Go with Xiaomi if you want zero headaches.
👉 Go with pTron if you want max speed for cheap.
