Written CairoVolt Warranty Delivery Within Egypt
High ambient temperatures in Egypt combined with inefficient 5V/1A legacy car chargers cause thermal throttling and battery degradation in modern iPhones.
The solution requires a Power Delivery (PD) 3.0 car charger with PPS where the phone supports it, so the charger negotiates voltage/current and shifts conversion heat off the phone’s power-management IC. Pair it with a USB-C cable rated for the negotiated power — a USB-A-only car adapter cannot provide USB-C PD/PPS.
No for USB-C PD. iPhone 15 needs a USB-C PD source. USB-A adapters typically stay near 5–12W and push more conversion heat into the phone path via adapters.
Cabin temperatures often exceed the phone’s comfortable thermal envelope. Any inefficient charger adds conversion heat on top of GPS, cellular radio, and a bright screen.
PD is the baseline. PPS helps some Android phones more than iPhone, but a quality PD 3.0 car charger still reduces heat versus legacy 5V adapters.
