Our Verdict
Being a travel charger, the boAt EnergyShroom PB331 with a cost of ₹1,499 deserves a place in your hand luggage due to its small size that doesn’t increase the volume of your luggage and magnetic attachment helps avoid another cable you have to find among other items you pack in a rush. The wireless charging speed is the only drawback of the product, which is more appropriate for charging during flights or taxi rides rather than before your boarding. Battery life is sufficient to ensure a whole day of using a phone without recharging it. The product passed airport security control successfully based on available information. If fast charging isn’t your priority and you prefer to take as little stuff as possible on trips, this device will suit you well.
