Table of Contents
If you want a power bank that can provide both wired fast charging and magnetic wireless charging, the boAt Energyshroom PB331 Magnacharge is an interesting option to consider.
It comes with a 10,000mAh battery, up to 15W magnetic wireless charging and up to 22.5W wired fast charging. It also has a two-way USB-C port, USB-A output, pass-through charging and a 12-layer Smart IC protection system.
The bigger question is whether these features make the PB331 a good choice for everyday use.
In this review, we’ll look at its specifications, design, charging features, battery capacity, wireless charging, advantages, limitations and current price to help you decide if it fits your needs.
boAt Energyshroom PB331 Magnacharge: Quick Overview
The Energyshroom PB331 Magnacharge is a 10,000mAh magnetic power bank designed for users who want more flexibility than a conventional wired power bank.
What makes the Energyshroom PB331 Magnacharge stand out is its combination of magnetic wireless charging and fast wired charging. It can deliver up to 15W wirelessly and up to 22.5W through a cable, while also supporting popular charging standards like QC 3.0, PD, and PPS.
It also has a USB-C port that works as both an input and output, along with a USB-A output. boAt says the device can charge up to three devices simultaneously using the USB-A port, USB-C port and magnetic wireless charging pad. However, simultaneous wired and wireless charging reduces the output speed.
That makes the PB331 more versatile than a basic power bank, particularly if you carry several devices.

Energyshroom PB331 Design and Build Quality
The PB331 follows a compact power-bank design rather than trying to be extremely thin.
Its dimensions listed by boAt are approximately 110.85 × 80 × 19.88mm, making it reasonably portable for a 10,000mAh model. The retail listing also describes the product as lightweight and durable.
The magnetic charging surface is the feature that immediately separates it from a standard wired power bank.
For compatible phones, the magnetic connection helps keep the phone aligned with the charging area. boAt also includes a Magna Charge Ring, which can be useful for making compatible non-magnetic devices work with the magnetic charging surface.
Is the PB331 easy to carry?
For daily commuting and travel, a 10,000mAh capacity is a practical middle ground.
A 20,000mAh power bank can provide more backup, but it is generally larger and heavier. The PB331 is better suited to someone who wants a balance between portability and battery capacity.
10,000mAh Battery Capacity
The PB331 uses a 10,000mAh Li-ion polymer battery with a rated energy of 38.5Wh. Its official support page lists a rated capacity of 6,750mAh at 5V, which is an important detail when comparing power banks.
This distinction is useful because the advertised 10,000mAh figure represents the battery’s nominal capacity. The amount of usable energy delivered to a smartphone will be lower because of voltage conversion and charging losses.
So, don’t assume that a 10,000mAh power bank will provide exactly two or more full charges to every phone.
The actual backup depends on:
- Your phone’s battery capacity
- Charging efficiency
- Wireless or wired charging
- Charging protocol
- Temperature
- Battery condition
- Power-bank conversion losses
How Many Times Can It Fully Charge Your Phone?
There is no single answer for every smartphone.
A phone with a smaller battery may receive more complete charging cycles than a phone with a larger battery. Wireless charging can also have greater energy losses than wired charging.
For this reason, it is better to treat the PB331 as a 10,000mAh backup power source rather than promising a fixed number of smartphone charges.
15W Magnetic Wireless Charging
Wireless charging is one of the main highlights of the PB331
It supports up to 15W magnetic wireless charging, and the magnetic surface helps keep a compatible phone securely aligned while it charges.
This can be particularly convenient when you don’t want to connect a charging cable every time your phone needs some extra battery.
However, the actual wireless charging speed depends on the smartphone and its supported charging standards. The maximum advertised output should not be interpreted as a guaranteed 15W charging speed for every phone.

22.5W Wired Fast Charging
If wireless charging isn’t your priority, the wired charging capability is another strong feature.
The PB331 supports wired fast charging of up to 22.5W and works with popular charging standards such as Quick Charge 3.0, Power Delivery (PD), and PPS
Its USB-C port can be used for both input and output, so you can recharge the power bank through it or use it to charge a compatible device.
This flexibility is useful because you don’t need separate ports for charging the power bank and using USB-C output.
USB-C and USB-A Ports
The power bank includes:
- 1 × USB-C two-way port
- 1 × USB-A output
- Magnetic wireless charging
The combination gives you several ways to charge your devices.
Can the Energyshroom PB331 Charge Multiple Devices?
Yes, according to boAt, the PB331 can charge up to three devices at the same time using the USB-A port, USB-C port and magnetic wireless charging pad.
However, there is an important limitation.
When wired and wireless charging are used simultaneously, the output is reduced to slower 5V charging for both according to boAt’s support documentation.
So, multiple-device charging is convenient, but you should not expect maximum charging speed for every device at the same time.
This is worth mentioning in an honest review because it gives readers a more realistic idea of how the product works.
Safety Features
The PB331 includes a 12-layer Smart IC protection system.
According to boAt, the protection system is designed to guard against issues including overcharging, short circuits, overheating and over-discharging.
The power bank also has LED indicators that show battery and charging status.
The official support page explains that the four white LEDs indicate the approximate battery level, while another indicator shows the charging state.
Pass-Through Charging
Another useful feature is pass-through charging.
This allows the power bank to charge connected devices while the power bank itself is being charged. boAt confirms that the PB331 supports this feature.
It can be useful when you have only one convenient power source and want to charge both the power bank and another device.
However, as with simultaneous charging, charging speeds can vary depending on the connected devices and power source.
Charging and Real-World Usage
The PB331 is designed to give users two main charging choices.
Wireless: Convenient magnetic charging with up to 15W output.
Wired: Faster charging through USB with up to 22.5W output.
For everyday use, wired charging is likely to be the better choice when speed matters, while wireless charging makes more sense when convenience is the priority.
Independent user feedback also shows mixed real-world experiences, including positive comments about portability and magnetic charging, while some users have reported heating during use. These are user reports rather than controlled laboratory measurements, so they should be treated as individual experiences rather than universal product behaviour.
Energyshroom PB331 Price in India
The official boAt product page currently lists the PB331 at ₹1,699, against an MRP of ₹4,499. The page also displays a promotional offer, so the final price can vary depending on the offer available at the time of purchase.
Marketplace pricing can also change.
Therefore, if you’re planning to buy it, check the latest Amazon price before placing an order.
