AI Verdict
A 12800mAh magnetic power bank with 22.5W wired and 15W wireless charging, built-in USB-C cable, and 1.1cm thickness, for iPhone 12-15 and USB-C Android users.
This power bank is a situational fit for users who specifically value its 1.1cm slimness, 191g weight, and the convenience of a built-in USB-C cable for 22.5W wired and 15W MagSafe-compatible wireless charging. Its 12800mAh capacity is adequate for several phone charges, making it suitable for light travel or daily top-ups.
If you need faster charging or higher capacity, look for power banks with 45W+ PD output or 20000mAh+ battery capacities.

Pros
- The integrated USB-C cable functions for both input and output, and doubles as a lanyard, reducing the need for extra cables.
- Supports 22.5W wired fast charging via the built-in USB-C cable.
- Offers 15W wireless fast charging, compatible with MagSafe for iPhone 12-15 series.
- Features a slim 1.1cm (0.43 inches) profile and weighs 191g (6.74 oz) for enhanced portability.
- Equipped with a 12800mAh Li-Polymer battery, providing multiple charges for smartphones.
- Includes an LED digital display for battery level and is aviation-compliant for air travel.
Cons
- Wireless charging for non-MagSafe Qi-enabled Android devices requires a separate MagSafe-compatible phone case.
- The built-in cable is USB-C, meaning older iPhones (pre-iPhone 15) need their own Lightning cable for wired charging.
- The 15W wireless charging speed is standard for magnetic charging but not the fastest available on the market.
- The 22.5W wired charging, while fast, is not top-tier for all modern devices that support higher wattage charging standards.
Dimension Scores
The 22.5W wired and 15W wireless charging speeds are above average for a budget slim power bank, but not best-in-class for all devices.
The product is described as crafted from high-quality, durable materials with a multi-protection safety system, including UL2056, CE, FCC, and ROHS certifications.
It offers MagSafe compatibility for iPhones and a universal USB-C port for Android, but magnetic wireless charging for Android requires a MagSafe-compatible case.
Its 1.1cm thickness, 191g weight, built-in cable/lanyard, and aviation compliance make it exceptionally portable.
Best For
- iPhone 12-15 users seeking magnetic wireless charging on the go.
- Travelers needing a compact, aviation-compliant power source with integrated cables.
- Users with USB-C Android devices who want both wired and magnetic wireless charging (with a MagSafe case).
- Individuals prioritizing a slim form factor and light weight for daily carry.
Not Recommended For
- Users needing the absolute fastest wired charging speeds (e.g., 45W+ for laptops or specific phones).
- Android users without a MagSafe-compatible case who want magnetic wireless charging without an additional accessory.
- Those requiring multiple output ports for simultaneous charging of many devices.
Watch Out For
- Magnetic wireless charging for Android phones necessitates purchasing a separate MagSafe-compatible case to function.
- The built-in cable is USB-C, so older iPhones (pre-iPhone 15) will require their own Lightning cable for wired charging, or an adapter for the integrated cable.
- The 12800mAh capacity, while stated, will not deliver a full 12800mAh to devices due to inherent energy conversion losses in power banks.

The power bank recharges via its built-in USB-C cable, which supports input. The exact recharge time depends on the wattage of the wall adapter you use.
Can I charge two devices at once?
The product description highlights a built-in USB-C cable for wired charging and 15W wireless charging, implying simultaneous wired and wireless charging is possible.

Buying Guide
When looking at power banks, you're balancing capacity, charging speed, and portability. A higher mAh means more charges, but also more bulk. Faster wattage means quicker top-ups, but your device also needs to support those speeds. The built-in cable here is a convenience factor, but make sure its type matches your primary device.
battery_capacity (12800mAh)
This number tells you how much juice the power bank holds. Think of it like a gas tank for your phone; 12800mAh is enough to fully charge most modern smartphones 2-3 times.
watts (22.5W wired / 15W wireless)
This indicates how quickly the power bank can deliver power to your device. Higher wattage means faster charging, like a stronger water hose filling a bucket faster. 22.5W wired is quick, and 15W wireless is standard for magnetic charging.
Ultra-Slim 1.1cm (0.43 inches) thickness
This is about how easily it fits into your pocket or bag. A 1.1cm thickness is genuinely thin, making it less noticeable than many bulkier power banks.
Built-in USB C cable
This means you don't need to carry an extra cable to charge your phone or to recharge the power bank itself. It's like having a charger and its cord always attached and ready to go.
Alternatives
If you need to charge multiple devices simultaneously or require significantly faster wired charging (e.g., for laptops), look for power banks with multiple high-wattage output ports (e.g., 45W+ USB-C PD) and larger capacities (20000mAh or more).
