Shanwu News Center covers wireless charging trends, plus technical and certification know-how on magnetic, 3-in-1, multi-in-1 and furniture wireless chargers — helping buyers and brands follow selection and compliance风向.
A bank card's black stripe needs roughly 4,000 gauss to wipe, while the magnets in a typical magnetic accessory measure only 50 to 200 gauss at the surface. The fragile ones are hotel keys, access badges and older transit cards, and the culprit is not the magnet but the alternating field during charging. Here is what the bench tests and Apple's own documentation say, plus a practical checklist.
On July 16, WPC Executive Director and CEO Paul Struhsaker visited Foryou Multimedia, a leading Chinese automotive wireless charging supplier. Together with the Qi 50W standards meeting held in Beijing in late June, the standards body has turned its attention to China twice within a month. The 25W certified era of in-car magnetic wireless charging, and a shift in supply-chain influence, are happening at the same time.
How much does a wireless charger cost you when it sits plugged in with no phone on it? Published power-meter tests show mainstream magnetic pads idle at just 0.02-0.05W, and even 3-in-1 stations stay around 0.3W - a few cents per year. The real waste hides in the roughly 40% conversion loss and in misaligned phones that keep the coil pinging all night. Here is the full math, item by item, plus a buying checklist.
With the Qi2 desktop ecosystem mature, the next frontier is contactless power: spatial charging and dynamic highway charging are moving from lab to pilot. This article uses real figures to show how far off they are.
That restaurant table that starts charging your phone the moment you set it down relies on a wireless charging module hidden beneath the tabletop. Before copying the setup at home, sort out five things first: desk material, penetration depth, heat, installation method and foreign object detection.
The WPC database now lists fifteen Qi2.2-certified phones from Apple, Samsung, Google and Motorola. Magnetic wireless charging is spreading beyond Apple, but picking the right accessory still means checking for native MPP support.
In 2026, five specs decide whether a wireless charger is worth buying: wattage, magnetic alignment, certification, cooling and multi-device support. Here is how to read them.
A magnetic charger holds the phone with magnets; a stand charger props it up like a dock. One wins on stability, the other on visibility. Here is how they differ in efficiency, cooling and where you use them.
Most magnetic wireless power banks are well within the airline capacity limit. What actually gets travelers stopped at security is a worn 3C mark, a recalled batch, or a label hidden under a magnetic ring. This guide walks through China's current civil aviation rules, the watt-hour math, what to do if your power bank is refused, and what to look for when buying in 2026.
Apple's updated MagSafe Charger now supports Qi2.2 at 25W and fast-charges Android phones like the Pixel 10. After iOS 26, iPhones (except the 16e) hit 25W on any Qi2.2 puck — cross-brand magnetic wireless charging is real.
We share trends, certifications and buying guides on magnetic, 3-in-1/multi-in-1 and furniture wireless chargers and Apple Watch charging to help buyers and brands follow the industry.
Magnetic wireless chargers focus on alignment and portability (car/desk); 3-in-1/multi-in-1 wireless chargers charge multiple devices at once (bedside/office).
Prioritize Qi certification; for export add FCC/CE. Factory-direct can support market compliance and audits.
