Add MagSafe to your pre-iPhone 12 iPhone
My wife really wants MagSafe on her iPhone for use in the car and to lose the hassle of cables. It was never really a big problem, but she got strangely jealous at how easy it is to charge my iPhone 13 Pro. Her 11 Pro does not have MagSafe and so she had to stick with cables or older wireless charging.
And then I saw the (deep breath!) RHOADA Clear For iPhone 11 Pro Case 5.8" Magnetic Case Compatible with MagSafe Charging, [Anti-Yellow] [Ultra Slim] [200% Drop Protection] PC + Silicone Frame Protective Cover… which was on sale for £12.99 from Amazon and decided to give it a try.
It works. I put her iPhone in the case and attached it to my MagSafe charger, and yes it actually works at a slightly slower rate than a true MagSafe phone. The fact it works, however, is enough for us.
