• ✅ Three output ports for simultaneous charging

URBN 20000mAh 22.5W — Best Triple-Port Budget Option

Price: ₹999

URBN has built a solid reputation in the Indian power bank market, and this 22.5W model delivers on that promise. With triple output ports, pass-through charging, and 12-layer circuit protection, it checks all the boxes at ₹999. The two-way fast charging means the power bank itself recharges quickly too.

• ✅ Pass-through charging — use while recharging the bank
• ✅ 12-layer circuit protection for device safety
• ✅ Two-way fast charge (charges itself quickly)

• ❌ No digital display
• ❌ 22.5W won't charge laptops meaningfully

Xiaomi Power Bank 4i — 🏆 Best Overall

Price: ₹1,999

The Xiaomi Power Bank 4i is the most polished option in this roundup. 33W PD 3.0 charging, a premium matte finish with anti-smudge texture, and Xiaomi's proven quality control make this the power bank to beat. It retains 80% capacity after 300 charge cycles, which is excellent longevity. If you can stretch to ₹2,000, this is our top recommendation.

• ✅ 33W PD 3.0 — fastest single-port charging here
• ✅ Premium matte build with anti-smudge coating
• ✅ 80% capacity retention after 300 cycles

URBN 20000mAh 35W — Best Mid-Range for Fast Charging

Price: ₹1,699

This is URBN's premium offering with 35W output that supports both PD and QC protocols. It can charge a MacBook Air to 40% in 30 minutes, making it a genuine laptop companion.

• ✅ 6 output options — 3 built-in cables + 3 ports
• ✅ Built-in Lightning cable for iPhones

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).
