Quick facts

Product overview

The boAt Energyshroom PB400 Pro is a pocket-sized 20,000mAh power bank from Indian audio and accessories brand boAt. It supports up to 22.5W fast charging through two output ports and is marketed for phones, tablets and earbuds. The Steel Blue variant is the listing we verified on Amazon India. A 20,000mAh pack at this capacity typically delivers three to four full charges for a modern smartphone, making it suitable for travel days or heavy use away from a socket.

Reasons to consider

• Verified selling price: ₹2,199 is confirmed by Amazon's own buy-box data, not just an advertised figure.
• 22.5W fast charging: Quicker top-ups than standard 10–12W budget banks, including support for fast-charge protocols on many Android phones.
• Two output ports: Charge two devices at once.
• Reputable retail chain: Sold by Cocoblu Retail and fulfilled by Amazon, which simplifies delivery and returns.
• Add-on warranty option: The listing offers an Onsitego 1-year extended warranty for ₹149 if you want extra cover.

Pros and cons

Pros

• Confirmed ₹2,199 price on Amazon.in
• 20,000mAh capacity in a compact body
• 22.5W fast charging, two output ports
• In stock, Amazon fulfilled

Cons

• The advertised "56% off / MRP ₹4,999" was not verified on the product page, so the true discount may be smaller
• 20,000mAh banks are still heavier than slim 10,000mAh options despite the "pocket size" claim
• No verified bank-card or coupon discount stack on this listing
• Same price has been seen recently, so it is not a once-only flash drop

Buyer fit

Good fit if you need a reliable high-capacity power bank for travel, commuting or outage backup and want fast charging without paying for premium brands. Less ideal if you prioritise the lightest possible carry — a 10,000mAh unit is easier in a pocket — or if you want laptop-class charging, which needs 45W+ PD output this bank does not claim.

Final verdict

At ₹2,199, confirmed on Amazon.in, the boAt Energyshroom PB400 Pro is a fair-to-good price for a 20,000mAh 22.5W power bank from a mainstream Indian brand. Treat the "56% off" framing with caution since the ₹4,999 MRP was not verified — judge it on the ₹2,199 selling price. Worth buying if you need one now; not urgent enough to impulse-buy if you do not.
