If you have been hunting for an affordable MagSafe power bank that does not compromise on charging speed, the boAt EnergyShroom PB331 might have caught your eye. Priced at ₹1,499, this 10000mAh magnetic wireless power bank promises 15W wireless charging along with 22.5W wired fast charging, making it an interesting option for iPhone users tired of tangled cables. In this review, we will break down what this power bank actually offers, where it shines, and where buyers might want to think twice before purchasing.

Product Overview

The boAt EnergyShroom PB331 is a magnetic wireless power bank designed primarily around Apple's MagSafe ecosystem, though it is not officially certified as a MagSafe accessory. According to the manufacturer, it uses a strong magnetic ring to snap onto compatible iPhones (12 through 16 series) and deliver 15W wireless charging without any cables involved. For devices that lack built-in magnets, boAt bundles a free MagnaCharge ring, which essentially turns any smartphone into a magnetic-charging-compatible device.

With a 10000mAh capacity, this power bank is built for all-day top-ups rather than replacing a wall charger entirely. It comes in an Ash Black finish and includes a 22.5W wired output supporting Power Delivery (PD) and Programmable Power Supply (PPS), which are the same fast-charging protocols used by most modern smartphones, including iPhones and several Android flagships.

Key Features Explained

Magnetic Wireless Charging with MagnaCharge Ring

The headline feature here is the magnetic snap-on charging, which competes directly with Apple's own MagSafe accessories at a fraction of the price. For iPhone 12 to 16 series users, the magnets should align automatically with the phone's internal magnetic ring, meaning you just need to place the power bank on the back and it should start charging wirelessly. For everyone else using Android phones or older iPhones, the bundled MagnaCharge ring is a thoughtful inclusion. You stick it to your phone case or back panel, and it gives you the same magnetic snap functionality. This matters because it widens the buyer pool significantly, someone with a Samsung or OnePlus phone does not have to sit out on the magnetic charging trend just because their device was not built with it in mind.

15W Wireless and 22.5W Wired Output

15W wireless charging is on the higher end for magnetic power banks in this price bracket, many budget alternatives cap out at 7.5W or 10W. Faster wireless output means shorter charging times when you're using the magnetic mode, which is particularly useful if you're stepping out and need a quick top-up before heading to a meeting or a flight. The 22.5W wired output with PD and PPS support is arguably the more practical feature for daily use, since wired charging is inherently more efficient than wireless. If you're in a real hurry, plugging in a cable will get your phone charged noticeably faster than relying on the magnetic connection alone.

10000mAh Battery Capacity

This capacity sits in a sweet spot for portability and usability. It's enough for roughly one and a half to two full smartphone charges, depending on your phone's battery size, though actual output will always be somewhat lower than the rated capacity due to conversion losses, this is standard across all power banks, not a boAt-specific limitation. For someone who needs power for a full day of travel or work without carrying a bulky 20000mAh brick, this capacity strikes a reasonable balance between backup power and pocket-friendly size.

12-Layer Smart IC Protection

Battery protection circuitry is one of those things buyers rarely think about until something goes wrong. According to boAt, the PB331 includes 12 layers of protection against overheating, overcharging, and short circuits. For buyers who plan to leave the power bank charging overnight or use it frequently with expensive phones, this kind of safeguard adds peace of mind, even if it's not something you'll notice in daily use unless there's an issue.

Pass-Through Charging

Pass-through charging lets you charge your phone and the power bank at the same time, using a single wall adapter for both. This is handy if you only have one charging point available, say, a single socket at a co-working space or an airport lounge, and need to juice up both devices simultaneously without waiting in turns.

Dual Port Connectivity

The power bank includes one 2-way USB-C port and one USB-A port. The USB-C port being 2-way means it can function both as an input for recharging the power bank itself and as an output for charging a connected device. Having both USB-C and USB-A means you're covered whether you're charging a newer USB-C device or an older gadget that still relies on USB-A cables.

Design and Build

The Ash Black finish gives the PB331 a fairly understated, professional look rather than a flashy one. Based on the available product information, exact dimensions and weight have not been specified by the manufacturer, so buyers who prioritize ultra-slim or ultra-light designs should check current listings for updated specifications before purchasing.

Pros

  • Strong 15W wireless output: Faster than most magnetic power banks in this price range, useful for quick top-ups without cables.
  • MagnaCharge ring included: Extends magnetic charging compatibility to Android phones and non-MagSafe devices, increasing overall value.
  • 22.5W wired fast charging with PD/PPS: Gives you a genuinely fast charging option when wireless isn't convenient or fast enough.
  • Pass-through charging: Practical for situations with limited charging points.
  • Reasonable price point: At ₹1,499, it undercuts many official MagSafe accessories while offering comparable wireless speeds.

Cons

  • Not officially MagSafe certified: While it targets iPhone 12-16 users, it is a third-party magnetic accessory, not an Apple-certified MagSafe product, so charging alignment and magnetic strength may vary slightly from Apple's own accessories.
  • 10000mAh may feel limiting for heavy users: Those who need multiple full charges across the day might find themselves reaching for a wall socket sooner than expected.
  • Exact weight and dimensions not specified: Buyers who care about pocket-friendliness should verify these details before buying, as they are not listed in the current product information.

Who Should Buy the boAt EnergyShroom PB331

This power bank makes sense for iPhone 12 to 16 users who want a MagSafe power bank without paying premium prices for Apple's official accessory or other high-end alternatives. It's also a solid pick for Android users curious about magnetic wireless charging, thanks to the bundled MagnaCharge ring. If you frequently commute, work from cafes, or travel and want a cable-free charging experience alongside a fast wired backup option, the PB331 covers both bases reasonably well.

Who Should Avoid It

If you need a power bank for multiple full charges across a long trip, a higher-capacity option like 20000mAh would serve you better, even if it sacrifices the magnetic convenience. Buyers who specifically want Apple-certified MagSafe accessories for warranty or compatibility assurance may also prefer to stick with official Apple products, despite the higher cost.

Value for Money

At ₹1,499, the boAt EnergyShroom PB331 positions itself as a budget-friendly entry into the magnetic wireless power bank wireless charging power bank category. Considering it offers 15W wireless output, 22.5W wired fast charging, and a free MagnaCharge ring for broader compatibility, it offers a fairly complete package for the price. Buyers comparing it against other magnetic power bank for iPhone options, such as those from Ambrane, will find boAt's combination of features and brand reliability competitive in this segment.

Our Verdict

The boAt EnergyShroom PB331 delivers a genuinely useful mix of features for its price, particularly the 15W wireless charging speed and the inclusion of the MagnaCharge ring, which extends its usefulness well beyond iPhone owners. As a MagSafe power bank alternative, it holds up reasonably well against pricier official accessories, though it isn't Apple-certified, which some buyers may see as a drawback. Its biggest limitation is the 10000mAh capacity, which suits daily top-ups but won't satisfy users needing multiple full charges on long trips. Overall, this is a solid pick for iPhone and Android users who want cord-free convenience without spending heavily, while those needing higher capacity or official MagSafe certification might want to explore alternatives.
