Note: the "Check price" buttons are plain store links; we earn nothing from them right now. Picks are based on facts we checked. How we pick.

A 20000mAh power bank charges most phones several times over, which makes it a useful pick for Diwali travel and wedding season. Most models in India fall into two groups. 22.5 W banks (about ₹890–1,800 on Flipkart on 30 Oct 2026) are fine for phones and earbuds. 45–70 W banks (about ₹2,000–3,100) can also top up many USB-C laptops and tablets. Decide which group you need first, then compare ports and warranty.

How to choose a 20000mAh power bank

Buying for a phone? See our best phones under ₹20,000 and best earbuds under ₹2,000. A power bank also makes a practical Diwali gift under ₹2,000. For laptop-class banks, check your machine against our best laptops under ₹50,000 list.

Flying this Diwali?

Keep the power bank in your hand baggage, not in checked bags. According to the DGCA advisory reported in January 2026, you cannot use it or charge it on board and it should not go in the overhead bin.

What we left out

The Anker 20000 mAh 45 W and Ambrane 85 W listings did not show a clear selling price in our search results on 30 Oct 2026, so we have left them out rather than guess. We also left out ratings and reviews; check them on the store page.

FAQ

Which is the best 20000mAh power bank in India for phones?

For phones and earbuds, a 22.5 W bank with Power Delivery (PD) 3.0 is enough. In our check on 30 Oct 2026, the Portronics Luxcell B 20K (₹1,113) was the cheapest PD 3.0 pick and the boAt EnergyShroom PB400 (₹1,299) listed both PD 3.0 and QC 3.0. If you want faster charging from a large brand, the Mi Power Bank 4i 33W was ₹1,999.

Can a 20000mAh power bank charge a laptop?

Only if the laptop charges over USB-C and the bank's USB-C port supplies enough power. Most thin laptops need 45–65 W. The 22.5 W models here are meant for phones. Check your laptop charger's wattage and pick a bank whose USB-C output matches it, such as the 45 W Philips or 65 W Noise in this list.

Can I carry a power bank on a flight in India?

Yes, but only in hand baggage. Under DGCA's dangerous-goods advisory reported in January 2026, power banks must not be used or charged during the flight, must not be plugged into seat power and must not go in overhead bins. Airlines also set their own capacity limits, so check your airline's rules before you fly.

Why does my 20000mAh power bank not give 20000mAh to my phone?

The rating is the capacity of the cells inside. Some energy is lost converting voltage and as heat, so the usable output is always lower than the label. How many full charges you get depends on your phone's battery size.

What do 22.5 W, PD and QC mean?

22.5 W is the maximum output the bank can supply. PD (USB Power Delivery) is the USB-C fast-charging standard used by iPhones, Pixels and most new Android phones. QC (Quick Charge) is Qualcomm's standard that many Android phones support over USB-A. Your phone charges fast only if it supports the same standard.
