The checklist
- Capacity: 10,000 mAh charges a phone about twice; 20,000 mAh suits laptops and long trips.
- Fast charging: match your phone (PD 20 W for iPhone, PD or QC for Android).
- Safety: buy only BIS-certified power banks with overcharge protection.
Set your budget
The power banks we researched sell for ₹1,200 to ₹2,800. Decide how you will use it first; the priciest model is often a skip for everyday needs.
India-specific tip
Airlines in India allow power banks up to 20,000 mAh in cabin baggage only; never put them in checked-in luggage.
