How to choose a phone charger

• Connector: most recent Android phones and iPhone 15 or later use USB-C. Older iPhones use Lightning.
• Wattage: the phone only draws the power it supports, so a higher-wattage USB-C PD charger is safe to use and can charge compatible devices faster.
• Fast-charging standard: USB Power Delivery (PD) is the most widely supported; some phones also support their own fast-charging systems.
• Cable rating: use a cable rated for the power you need, especially for laptops.
