Can I charge my MacBook/laptop with a power bank? ▼
Yes, but only with 45W+ models. Laptops need minimum 45W charging. MacBook Air, Dell XPS 13: 45W works. MacBook Pro 14-16", gaming laptops: need 65W+ ( Anker 87W at ₹5,489 or Stuffcool 65W at ₹2,499). 22.5W and 33W models CANNOT charge laptops.
Why does my 20000mAh power bank only charge my phone 2-3 times? ▼
Conversion loss is physics, not a defect. Power banks lose 25-30% capacity converting voltage. Real formula: (20000mAh x 0.7) / Phone Battery = Actual Charges. For 5000mAh phone: (20000 x 0.7) / 5000 = 2.8 charges. Advertised "4 charges" assumes 100% efficiency which is impossible.
Which brand is most reliable for power banks in India? ▼
Top reliable brands: Anker (18-month warranty, 4.4-4.5 ratings), Xiaomi (100K+ reviews, proven track record), Duracell (trusted global brand). For Indian brands: URBN is emerging with good quality. Avoid unknown brands even if cheaper.
Can power banks be taken on flights in India? ▼
Yes, in cabin baggage only. DGCA allows up to 27000mAh (100Wh) in hand luggage. Prohibited in checked baggage due to fire risk. 20000mAh = 74Wh (allowed), 30000mAh = 111Wh (NOT allowed). All power banks in this review except Spigen 30000mAh are flight-safe.
What's the difference between built-in cable vs regular power banks? ▼
Built-in cable power banks like Anker 87W and Anker Zolo 30W have USB-C cables permanently attached. Pros: No forgetting cables, always ready to use, no cable wear. Cons: Can't replace if cable breaks, usually heavier. Best for frequent travelers.
