ZUERST -B3 Ultra-thin power bank
🔹 Strong magnetic attachment & ultra-thin design: Experience a perfect fit, lightweight and burden-free. This magnetic power bank features a strong magnetic design and is only 7mm thick.
🔹 Incredibly Fast Charging:Equipped with an advanced lithium polymer battery, it also offers two charging methods: 15W wireless charging and 20W USB-C fast charging. It provides a fast and stable charging experience with less waiting time, making our lives and work more efficient.
🔹 Low-temperature ice magnetic battery + AI intelligent heat dissipation：Utilizing special battery cell materials, heat generation is significantly reduced during charging, achieving "charging without overheating." This avoids the overheating problem of devices/batteries during traditional power banks, maintaining a low device temperature while ensuring charging efficiency. This dual temperature control is achieved through both hardware and software.
🔹 Aesthetic texture：The power bank features an aluminum alloy , maintaining a consistent design with mainstream mobile phones, combining practicality and aesthetics, and meeting the current demand for "integrated device aesthetics."
🔹 Multi-dimensional security protection：Low-temperature charging prevents devices from aging hardware prematurely due to high temperatures, while also protecting battery cycle life and extending device lifespan.

Dual charging mode, no waiting for efficiency.
Supports simultaneous charging of two devices via both wireless and wired connections, eliminating the need to wait in line and improving the efficiency of charging multiple devices.Covering mainstream digital devices such as mobile phones, tablets, and headphones, one power bank can meet the charging needs of multiple devices, reducing the number of devices required.
Four-level LED power indicator
Equipped with 4 LED indicators, corresponding to 4 battery levels:
1 LED on: 0%-25%
2 LEDs on: 25%-50%
3 LEDs on: 50%-75%
4 LEDs on: 75%-100%
The battery status is clearly displayed, solving the problem of "vague battery levels and the need to guess remaining battery life" common with traditional power banks.
Nine-fold security protection mechanism
Overcharge, over-discharge, overvoltage, overcurrent, overpower, short circuit, magnetic field, and temperature protection to prevent abnormal charging; Recovery protection: Automatically resumes charging after the abnormal situation is resolved, improving ease of use.
Unobstructed use, more flexible scene adaptation
This power bank features an ultra-thin magnetic design that fits snugly against the phone, ensuring it doesn't obstruct the camera lens when attached. It's suitable for scenarios like taking photos, scanning QR codes, and playing games, solving the problem of traditional power banks obstructing functional areas while charging.
Various Color Options
The product comes in four colors to choose from, and custom colors can also be customized upon request.
1
What safety protection features does it have?
Built-in multiple safety protections, including overcharge, over-discharge, overvoltage, short circuit, and temperature protection, ensure a safe and stable charging process.
2
What are its charging methods? What is its charging power?
It supports two charging methods: 15W wireless fast charging + 20W wired fast charging, and can also perform wired and wireless charging simultaneously without waiting.
3
What is the battery capacity of the power bank?
Equipped with a 5000mAh high-density battery cell, it is small and compact yet provides good battery life.
4
How do I check the remaining battery level of my power bank?
The device is equipped with 4 LED power indicator lights, corresponding to the following power ranges: 1 light (0%-25%), 2 lights (25%-50%), 3 lights (50%-75%), and 4 lights (75%-100%), making the power status clear at a glance.
5
Will it get hot during charging? Will it damage the phone battery?
It won't get hot. It uses a low-temperature ice magnetic battery cell and intelligent heat dissipation design, along with multiple safety protections, so it won't get hot or damage the device's battery while charging.
6
Can I bring this power bank on the plane?
Yes. The product meets airline carry-on standards and can be taken directly onto the plane without worrying about baggage or carry-on restrictions.
7
Is the charging speed fast? How many full charges can it provide for an iPhone?
Hello, the B3 power bank offers exceptionally fast charging speeds. It features a dual-fast-charging solution with 20W USB-C wired fast charging and 15W wireless magnetic fast charging. When charging an iPhone 15, it can reach over 50% in just 30 minutes. Regarding charging cycles, it incorporates a high-quality polymer battery cell, maximizing capacity within its ultra-slim profile (refer to product specifications for exact battery capacity). For an iPhone 15 Pro, it can provide approximately 1-2 full charges—sufficient for handling emergency power needs throughout the day. It also efficiently charges two devices simultaneously via wireless and wired connections.
8
Is the magnetic pull strong? Will it come off easily? Will it work with my non-iPhone phone?
Rest assured, the B3 features a powerful magnetic module that provides exceptionally secure adhesion. It won't detach during everyday handheld use or minor jostling, though caution is advised during vigorous activity. Regarding compatibility, it natively supports all iPhone 12 and later models with MagSafe functionality. For other Qi-compatible Android phones or older iPhones, simply attach a universal magnetic ring to your device to seamlessly utilize its wireless magnetic charging. The wired interface remains universally compatible across all models.
9
Does wireless charging generate significant heat? Is it safe?
Heat control is one of the B3's major strengths! It employs ‘Low-Temperature Ice-Magnetic’ batteries and AI-powered cooling technology. By combining specialized cell materials with software algorithms, it reduces charging heat at its source, achieving ‘Charge Without Heat’ to better protect your phone's battery health. For safety, it features a nine-layer protection mechanism covering overvoltage, overcurrent, short circuits, overheating, and more, along with anomaly recovery capabilities to ensure a secure and reliable charging process.
10
Will attaching a power bank to my phone block the camera? Can I play games while charging?
No obstruction whatsoever! The B3 features a specially designed non-rectangular shape that avoids the camera module. Once attached, it won't block your phone's camera at all. This means you can charge while taking photos, scanning QR codes, or even playing games in landscape mode—all without any obstruction. The experience is incredibly smooth. This is a significant advantage over many traditional magnetic power banks.
