LAVESH BANSALShare this article
Power banks have become as essential as mobile phones in India. With smartphones consuming more power for 5G, large displays, and gaming — and with frequent power cuts in many North Indian cities — a reliable power bank is no longer optional.
boAt's EnergyShroom power bank series has become the bestselling power bank lineup in India in 2025. Here is our complete comparison of every boAt power bank worth buying, from the most compact to the most powerful.
What to Look for in a Power Bank in India
The four most important specifications for Indian buyers are: capacity (how much charge it holds), output speed (how fast it charges your devices), input speed (how fast the bank itself recharges), and size (whether it fits in a pocket or requires a bag).
The most critical number is output wattage — not just mAh capacity. A 20000mAh bank that outputs 10W charges your phone slowly. A 20000mAh bank that outputs 45W charges your phone at the same speed as a wall charger.
boAt EnergyShroom PB400 Pro — Best 20000mAh Under Rs. 1500
Capacity: 20000mAh
Maximum output: 22.5W two-way fast charge
Ports: 1 USB-C (input plus output), 2 USB-A ports, total 3 output ports
Special: Pass-through charging (charge the bank and your device simultaneously)
Weight: Compact design
The PB400 Pro is our bestselling power bank at Nalanda Enterprises. The three-port design lets you charge your phone, earbuds, and smartwatch simultaneously. The 22.5W fast charging fills your smartphone from 20 to 80 percent in approximately 45 minutes. Pass-through charging means you can plug the power bank into the wall at night and also charge your phone through it — no need for two separate charging cables.
Best for: Students, daily commuters, people who need to charge two to three devices from one bank.
boAt EnergyShroom PB400 Turbo X — Best 20000mAh with 35W Charging
Capacity: 20000mAh
Maximum output: 35W super fast charging
Protection: 12-layer smart protection system (overvoltage, overtemperature, short circuit)
Compatibility: Android, iPhone, tablets, earbuds
The Turbo X version of the PB400 upgrades the output to 35W — fast enough to charge most laptops at low power mode. The 12-layer protection system is noteworthy for Indian electrical conditions, where voltage fluctuations are common. This is the right choice if you own a newer iPhone or Samsung Galaxy flagships that support 25W plus fast charging.
Best for: iPhone 15 users, Samsung Galaxy owners, laptop charging on the go.
boAt EnergyShroom PB600 PowerPulse — Best for Laptop Charging
Capacity: 27000mAh
Maximum output: 160W total (100W USB-C output)
Ports: 2 USB-C (two-way), 2 USB-A
Cable included: 100W USB-C to C cable in the box
Special: Charges MacBooks and Windows laptops at full speed
The PB600 PowerPulse is in a different category from compact phone power banks. With 100W USB-C output, it charges MacBook Air and Pro laptops at the same speed as the original Apple power adapter. The 27000mAh capacity means one full charge of a MacBook and 1.5 full charges of an iPhone 15 Pro.
This is the right choice for work-from-home professionals, frequent travelers, and content creators who need laptop power throughout the day.
Best for: Laptop users, content creators, frequent flyers, remote work professionals.
Power Bank Buying Guide — Common Indian Questions
Can a power bank charge a laptop? Yes — but only if it has a 45W or higher USB-C output. The PB600 at 100W handles all major laptops.
How long does a 20000mAh power bank last? It charges an average 4000mAh smartphone battery 4 to 4.5 times fully.
Is fast charging safe for the battery? Yes — modern fast charging uses adaptive technology that slows down automatically as the battery approaches full charge.
