Frequently Asked Questions
Q: What vehicles is this 20W wireless charging module compatible with?
A: The module's weld lead input supports 9V–30V, making it compatible with standard 12V passenger vehicles, 24V trucks, vans, and most other automotive electrical systems. Simply connect the leads to a switched power source in your vehicle's console or dash for a clean, built-in wireless charger.
Q: Will this wireless charger module work with my iPhone?
A: Yes. iPhones with Qi wireless charging support (iPhone 8 and later) are compatible. Apple devices will receive up to 7.5W–10W of wireless charging power, as determined by Apple's open protocol. Android Qi devices can receive up to 15W or 20W depending on the phone's supported fast-charge protocol.
Q: How thick of a surface can the module charge through?
A: The module can transmit through up to 2–6mm of non-metallic material, such as plastic trim panels, wood, or acrylic. This means you can mount it beneath a desk surface or behind a car console panel for a seamless, hidden wireless charging pad.
Q: Does this module require a special power adapter?
A: For bench or desktop use, connect via the Type-C port using a QC or PD adapter (5V, 9V, or 12V). For vehicle use, connect the solder weld leads directly to your 12V or 24V vehicle power supply — no additional adapter is needed for automotive installations.
