5V 2A Wireless Power Supply Module – High-Current Wireless Charging Transmitter and Receiver Coil Kit

Product Description The 5V 2A Wireless Power Supply Module Kit is a high-power induction solution designed for short-distance wireless energy transfer. This kit consists of a dedicated transmitter module with a high-frequency induction coil and a matching receiver module that outputs a stable 5V DC. Unlike standard low-power wireless modules, this version utilizes the XKT-801 high-current chip, capable of delivering up to 2 Amps of current. This makes it ideal for charging high-capacity lithium batteries, powering robotic limbs, or creating waterproof electronic devices where physical charging ports are undesirable. The magnetic resonance technology allows power to pass through non-metallic materials like plastic, wood, or glass.

Key Features

• High Current Output: Delivers up to 2A at 5V, sufficient for powering Raspberry Pi boards, large LED arrays, or fast-charging mobile devices.

• Large Sensing Range: Maintains stable power transmission at a distance of 2mm to 8mm between the transmitter and receiver coils.

• Stable Voltage Regulation: The receiver features an on-board buck-boost stabilization circuit to ensure a steady 5V output regardless of minor distance fluctuations.

• High-Frequency Induction: Operates at a frequency that maximizes energy transfer efficiency while minimizing heat generation in the surrounding environment.

• Industrial Grade Design: Built with high-quality ultra-thin copper coils and heat-dissipating PCB layouts for continuous long-term operation.

Technical Details

• Core Circuitry: Features the XKT-801 high-power wireless charging chip for intelligent energy management and oscillation control.

• Inductive Coupling: Works on the principle of electromagnetic induction; the transmitter generates a high-frequency magnetic field that the receiver converts back to DC.

• Efficiency Optimization: Achieves peak efficiency when the coils are perfectly aligned and separated by approximately 3-5mm of non-metallic material.

• Standby Power: Features an ultra-low no-load current draw, making it energy-efficient when no device is placed on the charging area.

• Thermal Management: The transmitter PCB is designed to dissipate heat effectively; however, adequate airflow is recommended for high-load (2A) applications.

• Coil Construction: High-quality multi-strand oxygen-free copper litz wire used to reduce skin effect losses at high frequencies.

• Protection Mechanisms: Includes internal over-temperature protection and output short-circuit protection to prevent hardware failure.

• Non-Interference: Designed to operate without interfering with standard WiFi or Bluetooth signals in the vicinity.

• Input Compatibility: Specifically tuned for 9V to 12V DC input, allowing it to be powered by standard industrial adapters or 3S Li-Po batteries.

• Output Ripple: Low ripple voltage ensures the output is safe for sensitive digital electronics and microcontrollers.

• Physical Durability: Coils are flexible and can be glued or taped inside enclosures, while the PCBs feature standard M3-compatible mounting points.

• Bi-Directional Alignment: For maximum power, the coils should be parallel; angular deviation will result in reduced current capacity.

• Material Transparency: Power successfully penetrates plastic, wood, acrylic, and glass; it will not function through metal or carbon fiber shields.

• Plug-and-Play Setup: Comes with pre-soldered wires for immediate connection to power sources and loads.

• Miniature Controller: Despite the high current, the control PCBs are small enough to fit inside compact wearable or portable enclosures.
