boAt EnergyShroom PB300 Pro 10000mAh 22.5W Power Bank

Ten thousand milliampere hours in an aluminium alloy body is a different proposition from the same capacity in plastic. The boAt EnergyShroom PB300 Pro feels like something worth carrying — solid without being heavy, slim enough to slip into a jacket pocket, and finished well enough that it doesn’t look out of place next to a premium phone. For daily commuters, students, and professionals who need reliable backup power without the bulk of a 20,000mAh unit, the PB300 Pro hits the right balance between capacity and portability.

Fast Charging Performance

22.5W fast charging moves compatible smartphones through the lower battery percentages at a pace that makes a meaningful difference — a 20-minute top-up during a commute or lunch break returns enough charge to cover the rest of the afternoon. The USB-C two-way port handles both input and output with the same cable, which simplifies the carrying load: one cable charges the bank and charges your devices, nothing else required.

Dual Output and Pass-Through

The dual output configuration — USB-A and USB-C — allows two devices to charge simultaneously without one blocking the other. A phone and a pair of earbuds, or a phone and a smartwatch, draw power concurrently without meaningful speed reduction. Pass-through charging lets the bank recharge from a wall outlet while continuing to power connected devices — useful in hotel rooms or airport lounges where outlets are limited and waiting in sequence isn’t practical.

Protection and Indicators

12-layer Smart IC Protection covers overcharging, overheating, short circuits, and voltage fluctuations passively — the kind of safety engineering that’s invisible until it matters. The LED battery indicators show remaining capacity at a glance without needing to connect a device to check. Compatible with smartphones, earbuds, smartwatches, and other USB-powered accessories, the PB300 Pro covers daily device needs from a unit compact enough to carry without noticing it.
