Wireless power banks make it possible to enjoy the convenience of cordless charging by sacrificing some speed of the process. However, this may be acceptable in case someone is tired of untangling wire in order to charge their phone. Moreover, it will help to get rid of the mess and keep devices safe since a user will not have to carry a bunch of tangled wires everywhere. In this context, the boAt EnergyShroom PB331 wireless power bank was developed for such cases. In this review, it will be evaluated during regular usage during two weeks: its magnetic grip, wireless charging speed, as well as durability when thrown into a bag will be assessed.
Snap-On and Go! The Magic of Magnetism
Let’s start off by imagining that we are hurriedly getting out of our houses and running late for something, but our phones' batteries are dying, so instead of trying to plug them into chargers using cables, we use a handy power bank that we snap onto our smartphones. In the case of the boAt EnergyShroom PB331, this idea has been brought to reality with the help of a 10000mAh capacity and a rather efficient 15W wireless charging that makes it suitable for iPhone 12, 13, 14, 15, and even upcoming iPhone 16 users. Moreover, this strong magnet will not only make charging process faster but also will position your phone properly without any wire entanglements.
But What if I Want More Power? Wired Charging Solution
If you think that 15W of wireless charging is insufficient for your needs or if you want to charge your phone fast, the EnergyShroom PB331 also includes 22.5W of wired charging that has Power Delivery (PD) and PPS capabilities. This means that the charging process will be very quick and will work with iPhones, Android smartphones, and other devices. I consider this function to be rather convenient since I often use my portable charger when I have to go somewhere for a long period of time: do some street photography or go visit my relatives in another part of town. It is extremely helpful in the situations when I have to spend many hours on a train or in a busy marketplace.
Moreover, boAt provides its customers with a free MagnaCharge ring which greatly increases compatibility and makes the charging process faster and safer since even non-magnetic devices become suitable for this task.
Stylish Design and Maximum Protection
The boAt EnergyShroom PB331 is not only about power, but also about design and protection features. Its ash black color gives it a premium look and makes it easy to combine with everything else. Its size is rather small so it will easily fit in any pocket or a small bag. Nimmu Technologies guarantees the safe and reliable charging of your devices. The EnergyShroom PB331 includes pass-through charging option so you can recharge your phone while the power bank itself is charging. In addition, it has advanced smart circuit protection with 12 layers of safety and will prevent such problems as overcharging, overheating, or short circuits.
From my point of view, the beauty of magnetic power banks lies in the fact that it frees up mental space which otherwise is occupied with such activities as finding the right cable, untangling the wire knot, and so on. In general, it makes charging process more convenient and less annoying.
Should You Get This 10000mAh Portable Charger?
In conclusion, the boAt EnergyShroom PB331 is a good product that can be interesting for people who prefer not to have any cables or wires during their charging process. It is quite suitable for iPhone 12 to 16 users, frequent commuters, professionals who need a quick power top-up during their working day, and people who need a fast and convenient way to give their phones an additional charge without connecting them to any wall sockets. However, if your priorities are to charge different high-wattage devices simultaneously, like laptops, or charge completely drained batteries from a single power source as quickly as possible, you may consider purchasing a bigger power bank.

Our Verdict
The boAt EnergyShroom PB331 wireless power bank can be considered one of the best offers at ₹1,499 in terms of convenience because it provides reliable wireless charging of a magnetic-compatible phone without problems. The magnetic grip of the boAt EnergyShroom PB331 wireless power bank does not slip off and stays on the phone even while moving, as it is supposed to. The wireless charging speed is slightly lower than when using a wire but it is an obvious drawback of any wireless power bank, and not of this particular one. Moreover, the power bank is not powerful enough to provide full phone charging; however, the price-to-quality ratio of this device is good and the build quality is quite decent. The small dimensions allow carrying the power bank everywhere. Overall, this device is highly recommended to iPhone owners and all those who value the convenience and affordability.
