boAt Energyshroom PB400 Pro 20000mAh 22.5W Power Bank ₹1,899

PHONE AT 9% AND THE DAY ISN'T OVER?

You know the feeling. It's 6 PM, you're still out, the maps app is open, and the battery icon has just turned red. A power bank is the cheapest insurance against that panic, and a 20000mAh one can usually refill a typical phone more than once.

The boAt Energyshroom PB400 Pro is one of the popular picks in that space right now. It's selling at ₹1,899 against an MRP of ₹4,999, a 62% discount. Let's see whether it belongs in your bag.

WHO IT'S FOR

This suits daily commuters, students and travellers who want one power bank that can top up a phone, earbuds and a smartwatch through the day. It's also a sensible pick for anyone who wants fast charging on both Android and iPhone without carrying a separate brick for each.

If you need to charge a laptop, look elsewhere. At 22.5W this is built for phones and small gadgets, not notebooks.

DESIGN AND BUILD

boAt calls this a pocket-size, compact design. It measures about 9.3 x 6.5 x 3.1 cm, which is short and chunky rather than long and flat, so it slips into a bag pocket or a jacket easily. The listed weight is about 325 grams, which is normal for a 20000mAh pack. The colour here is Carbon Black, and it comes with boAt's 1-year warranty.

KEY FEATURES IN REAL-WORLD TERMS

• •20000mAh capacity: Plenty of reserve for a weekend trip or a long day of navigation, calls and streaming.
• •2-way 22.5W fast charging: The Type-C port works both ways, so it charges your phone fast and also refills the power bank itself faster than old micro-USB packs. boAt lists support for Quick Charge 3.0, Power Delivery and PPS, which covers most modern Android phones and iPhones.
• •Three outputs: One Type-C and two USB-A ports, so you can charge up to three devices together. That's handy when a friend's phone is also dying.
• •Pass-through charging: You can plug the power bank into the wall and charge your phone from it at the same time. Useful in hotel rooms with only one free socket.

HOW IT COMPARES

At this price you'll also see the Xiaomi Power Bank 4i 20000mAh, which offers faster 33W charging for a little more money, and Ambrane's 20000mAh packs with a built-in Type-C cable, which save you carrying a separate cable. The boAt sits in the middle: a familiar brand, a compact shape and three ports, without the extra speed of the Xiaomi.

VALUE FOR MONEY

At ₹1,899, you're paying well under half the listed MRP for a 20000mAh, 22.5W, three-port power bank from a well-known Indian brand. For phone and earbud charging, that's a fair deal.

VERDICT

The boAt Energyshroom PB400 Pro is a solid, compact 20000mAh power bank for everyday phone charging at a strong 62% off. If you want fast charging for phones and gadgets and don't need laptop support, it's worth a look. Check the latest price on Amazon before the deal changes.
