Qi mini wireless charging receiver with TI BQ51013, 5V/1A 5W

Product detailed description

This miniature Qi-standard wireless charging receiver module is based on the Texas Instruments BQ51013 integrated circuit, featuring a synchronous rectifier and a linear regulator. It provides a stabilised 5 V output with a current of up to 1 A, enabling wireless power or charging for your own projects without a single connector. Thanks to the thin, flat ferrite-shielded coil and a small PCB, it easily fits into 3D-printed enclosures, watches, sensor nodes, or encapsulated IoT devices where waterproofing is required. The module is compatible with common Qi transmitters, including 9V fast-charging pads.

Package contents:

• 1× Qi wireless charging receiver module with BQ51013

Note:

• The module provides a stabilised 5 V output. To charge Li-Ion/Li-Pol batteries, an additional charging module is required (e.g. with a TP4056 circuit).
• For correct operation, the receiver coil must be placed as close as possible to the centre of the transmitter coil – metal objects between the coils prevent energy transfer.
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.
