Dual Wireless Fast Charging Power Bank
- Product Function Specification
Document Version: V1.2
Update Date: 2026.01.27
1.Product Overview
This power bank is a high-performance portable charging device specially designed for the European
and American markets. It features dual-sided wireless charging as its core differentiator and supports
22.5W wired fast charging. The circuit design strictly complies with CE (EU) and FCC ID (US)
certification standards. With a simple and practical appearance, it meets efficient charging demands
while delivering convenient user experience, suitable for daily commuting, business trips, outdoor
travel and other scenarios.
2.Dual-Sided Wireless Charging Module
Hardware Configuration: Both sides of the device are equipped with independent 15W magnetic
single-coil wireless chargers (the main side has a visible ring-shaped charging module with a
lightning icon in the center). It supports simultaneous wireless charging for two devices, allowing
two mobile phones or compatible magnetic devices to be powered at the same time without
extra data cables, satisfying the charging needs of users with multiple devices.
Smart Sensing Technology: Built-in Q-value sensing function. The wireless charging mode is
activated automatically when a device approaches the corresponding coil area, with sensitive
and fast response, compatible with mainstream magnetic charging devices.
Safety Adaptation Logic: When charging multiple mobile phones simultaneously, the device
automatically switches to 5W slow charging mode to effectively avoid overloading and ensure
charging stability and device safety.
3. Wired Charging Function
Interface Specification: Equipped with a Type-C bidirectional fast charging port, which is highly
universal for both input (self-charging) and output (powering external devices), compatible
with most electronic device interface standards.
Output Parameters: Supports 22.5W wired fast charging output for efficient power
replenishment. In slow charging mode, it provides stable 5V/2A output, suitable for devices with
special power requirements (such as small digital products).
Safety Adaptation Logic: When charging multiple mobile phones simultaneously, the system
switches to slow charging mode to prevent overloading, ensuring stable and safe charging.

improved production efficiency.
PCB components are neatly arranged with rational layout, matching the housing design and
balancing internal practicality and external aesthetics.
5.2 Market Compliance Standards
The circuit design strictly meets CE (EU) and FCC ID (US) certification requirements, ensuring lawful
sales and use in European and American markets.
6. Appearance and Form
Integrated rounded body with smooth edge transitions for comfortable hand feel.
Symmetrical dual-sided wireless charging areas with fine surface texture, presenting a
minimalist, high-tech style.
Portable size and moderate weight, easy to store and carry for daily use.
FCC Warning
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
NOTE 1: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of
the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
-Consult the dealer or an experienced radio/TV technician for help.
NOTE 2: Any changes or modifications to this unit not expressly approved by the party responsible
for compliance could void the user's authority to operate the equipment.
The device has been evaluated to meet general RF exposure requirement. The device can be used
in portable exposure condition without restriction.
