MagSafe + Qi2 wireless charging compatibility, how do you flag it?

Three overlapping wireless standards customers need filtered:

• MagSafe, Apple proprietary, 15W on iPhone 12+, magnetic alignment. MagSafe-certified accessories pass Apple’s technical review (similar to MFi). MagSafe-compatible (lowercase, no cert) is the loophole, works magnetically but charges at 7.5W only.
• Qi2, cross-brand open standard launched 2024. 15W with magnetic alignment (matches MagSafe). Galaxy S24+, Pixel 9+, and iPhone 13+ all support Qi2. Adopted by Anker, Belkin, Mophie, Spigen. Qi2 cert is via WPC (Wireless Power Consortium), ~$2.5k cert fee.
• Legacy Qi (5W / 7.5W), older Samsung phones, AirPods cases. Still relevant for older device support.

On Magento, each spec is a product attribute (boolean or multi-select). PDP shows a “Works with:” row: MagSafe (15W) · Qi2 (15W) · USB-C PD (20W). Layered nav filter on the wireless-charger category page: “Qi2 only” / “MagSafe-compatible” / “MagSafe-certified”. The distinction matters because customers complain on Amazon reviews when a “MagSafe” charger only delivers 7.5W, the cert badge prevents that.

Add USB-C PD (Power Delivery) flagging for cables and wall chargers: 18W / 20W / 30W / 45W / 65W / 100W / 240W tiers. iPhone 15+ caps at 27W; MacBook Pro 16” needs 140W. Wrong wattage = slow charging = returns.
