5V 2A Wireless Transmitter Receiver Charging Coil

Inductive Wireless Power Transfer: Uses electromagnetic induction via matching transmitter and receiver coils to deliver wireless power across short physical air gaps.

High Output Current (5V 2A): Delivers a regulated 5V DC output up to 2A on the receiver side, capable of powering high-draw electronics or charging lithium batteries.

Compact Copper Coil Modules: Features ultra-thin, flexible transmitter and receiver copper coils designed to fit easily inside small custom enclosures and tight prototype housings.

Integrated Control & Regulation Circuitry: Transmit and receive modules include onboard voltage regulation and power management to ensure stable power delivery and protect connected devices.

Contactless & Sealed Operation: Enables completely sealed, waterproof, or dustproof device designs by removing the need for exposed physical charging ports or electrical contacts.

Wide Input Range: Flexible transmitter input operating range allows smooth integration with standard 5V, 9V, or 12V DC power adapters or battery packs.

Housing & Coil Style: High-purity multi-strand copper induction coils mounted on insulating substrate backings with connected PCB control modules.

Contact & Terminal Style: Color-coded lead wires (Red/Black) on both transmitter and receiver PCB modules for quick soldering to power inputs and loads.

Technical Specifications:

Input Voltage (Transmitter): 9V–12V DC (or standard 5V DC depending on supply configuration).

Output Voltage (Receiver): 5V DC regulated.

Max Output Current: 2A peak.

Coil Outer Diameter: Approx. 40mm – 43mm.

Inductive Gap Distance: 1mm–8mm recommended.

Color: Copper coils with green PCB circuit modules.

Usage Advice: Keep magnetic metal objects (e.g., iron filings, steel plates) out of the gap between coils during operation to prevent thermal heat buildup. Pay strict attention to positive (+) and negative (-) wiring polarity.

Maintenance: Ensure coils remain flat and free from sharp bends or physical punctures. Store in anti-static packaging when not in active use.

Essential Wireless Power Kit: Position as the ultimate solution for makers creating waterproof electronics, custom contactless charging pads, sealed IoT sensors, medical devices, and mobile robotics.

Highlight High-Amperage 2A Output & Port Elimination: Emphasize its impressive 2A charging capability, enabling fast wireless battery top-ups while completely eliminating mechanical wear on USB charging ports.

Recommended Cross-Sell Add-ons: Pair with TP4056 1A lithium charging module Type-C, 2 x 18650 Lithium Battery Shield Power Expansion Board, TP5410 5V 1A LiPo Charger & Boost Converter, and ESD antistatic mat 50x40CM PCB Welding Mat.
