Amazon: boAt Energyshroom PB400 Pro 20,000mAh 22.5W Power Bank at ₹2,199

At a glance

The boAt Energyshroom PB400 Pro — a 20,000mAh, 22.5W fast-charging power bank in Steel Blue — is listed on Amazon India at ₹2,199, and that selling price is confirmed on the product page. A discount of 56% off an advertised MRP of ₹4,999 was promoted alongside the listing; the merchant page confirms the ₹2,199 price and shows the unit in stock, but does not independently display the ₹4,999 MRP, so treat the percentage-off figure as advertised rather than verified.

Product overview

The Energyshroom PB400 Pro is boAt's compact 20,000mAh power bank. It supports 22.5W fast charging and offers two output ports, so it can top up a phone and a pair of earbuds or a second device at once. boAt markets it as pocket-sized for its capacity class, and it is positioned for everyday carry and travel backup rather than laptop-class charging — 22.5W is well suited to phones and accessories but is below the wattage most USB-C laptops expect.

Reasons to consider

• 20,000mAh is enough for roughly three to four full phone charges, useful for travel or long days out.
• 22.5W fast charging meaningfully cuts top-up time versus basic 10W banks.
• Two output ports let you charge two devices simultaneously.
• At ₹2,199 it sits at the competitive end of the branded 20,000mAh fast-charging segment.
• Sold by Cocoblu Retail and fulfilled by Amazon, which simplifies delivery and returns.

Pros and cons

Pros

• Confirmed ₹2,199 selling price on the merchant page
• Large capacity with genuinely fast output
• Compact-for-capacity design from a mainstream Indian brand

Cons

• The advertised 56% discount is measured against an MRP the merchant page did not independently confirm
• 22.5W is not enough for laptop charging
• Price can move quickly; check the listing at checkout

Buyer fit

This suits commuters, students and travellers who want a high-capacity branded power bank without spending on premium 30W+ models. If you only need a single phone top-up occasionally, a smaller 10,000mAh unit will be lighter and cheaper. If you need to charge a laptop, look at 45W+ options instead.

Final verdict

A solid buy if you need a 20,000mAh fast-charging power bank: the ₹2,199 price is confirmed on Amazon and competitive for the spec. Just don't anchor on the advertised 56% off figure — judge it against what similar 20,000mAh 22.5W banks cost today, not against the ₹4,999 MRP.
