Factors to Consider When Choosing a Dual Charger for iPhone and Apple Watch

These elements impact how well an iPhone charges when using an Apple watch charger:

Type of charger

Apple watch chargers stick to the watch’s back using a magnetic cable or dock. It’s different from iPhone chargers that need a USB-C to Lightning cable or a wireless pad. 

The magnetic charger is for the Apple watch only, not other gadgets. 

However, some chargers like the MagSafe Duo Charger, or certain third-party ones, can charge both the Apple watch and the iPhone wirelessly.

iPhone Model

Wireless charging isn’t for all iPhones. Only models from iPhone 8 onwards have this. Older models need a cable to charge. 

So, with an iPhone 8 or newer, a dual charger will work for both your Apple watch and iPhone. But, it’s a no-go for older models with an Apple watch charger.

Power Adapter

The adapter you use matters for charging speed and efficiency. Apple watch chargers need a 5W adapter, but iPhones need a 20W adapter for best results. 

A lower-wattage adapter slows down the charge and is less efficient. A higher wattage adapter speeds it up but might create more heat, which could cut down your gadgets’ battery life

The MagSafe Duo Charger needs at least a 15W adapter to charge both gadgets together.

System conditions

Your gadgets and charger’s system conditions are also crucial in the charging process. Temperature, battery level, system activity, and connected accessories can change the power delivery and optimization. 

For instance, an iPhone in low power mode charges quicker than in normal mode. Also, if there’s a Lightning accessory like headphones connected to your iPhone, the wireless charging drops to 7.5W to meet regulatory standards.
