Product Description The 5V 2A Wireless Power Supply Module is a high-power inductive charging solution designed for applications where physical connectors are impractical or impossible to use. This kit consists of a transmitter circuit with an induction coil and a receiver circuit with its own matching coil. It uses electromagnetic field induction to transfer energy through air, plastic, or wood. Unlike standard low-power wireless modules, this version is capable of delivering up to 2 Amperes at 5 Volts, making it powerful enough to charge smartphones, power Raspberry Pi boards, or run high-torque DC motors in waterproof robotic projects.
Key Highlights
High-Current Output: Capable of delivering a steady 2A, which is significantly higher than standard DIY wireless charging modules, suitable for power-hungry electronics.
Fully Regulated Output: The receiver module includes a buck-boost or regulation circuit to ensure a stable 5V output even if the distance between coils fluctuates slightly.
Non-Contact Power: Ideal for sealed, waterproof, or dustproof enclosures where you cannot have an external charging port.
Broad Transmission Gap: Works effectively across a 2mm to 10mm gap. Note that thinner gaps generally yield higher current and efficiency.
Easy Integration: Simple two-wire input (Transmitter) and two-wire output (Receiver) make it a "drop-in" wireless power solution for any project.
Technical Specifications
Transmitter No-load Current: ~30-50mA
Coil Inductance: 20uH
Receiver Circuit Dimensions: ~24mm x 10mm
Transmitter Circuit Dimensions: ~17mm x 12mm
Operating Temperature: -40°C to +85°C
Installation Tip from Robogears For maximum efficiency, the transmitter and receiver coils must be aligned parallel to each other. If the coils are tilted or off-center, the power transfer will drop significantly. While the module can handle a 10mm gap, it performs best at 3mm to 5mm. Because high-current wireless transfer generates heat, ensure there is adequate ventilation or a small heatsink on the transmitter IC if you plan to draw a full 2A for extended periods. Do not place metallic objects between the coils, as they will interfere with the magnetic field and heat up rapidly due to eddy currents.
Note: This kit includes both the Transmitter and Receiver modules with coils. A 12V DC power source is required for the transmitter side. Product images are for illustration purposes only.
