Buying Guide: How to Choose a Power Bank
- Capacity: All picks here are 20000mAh — enough to charge most smartphones 3–4 times. This is the sweet spot for capacity vs. portability.
- Charging Speed: 22.5W is fine for phones. If you want to charge a laptop (even slowly), look for 35W+ PD output (Ambrane PowerMini 20 or URBN 35W).
- Number of Ports: If you charge multiple devices daily, prioritize models with 3+ output ports. The Lifelong 6-Output is unmatched here.
- Build Quality: Xiaomi leads with its matte anti-smudge finish. Budget options from Amazon Basics and Lifelong use standard plastic.
- Flight Approval: All 20000mAh power banks (74Wh) are within the 100Wh airline limit — safe for carry-on luggage.
- Pass-Through Charging: If you want to charge your phone while the power bank itself is plugged in, look for pass-through support (URBN models have this).
Our Verdict
For most people, the Xiaomi Power Bank 4i (₹1,999) is the best overall choice — 33W charging, premium build, and proven reliability. On a tight budget? The Amazon Basics (₹899) delivers 22.5W fast charging for less than a thousand rupees. If laptop charging matters, grab the Ambrane PowerMini 20 (₹1,899) or the URBN 35W (₹1,699).
