Anker Charger 20W 1C White — Anker Nano Charger
The Anker Charger 20W 1C White is a single-port USB-C wall charger, roughly the size of a standard 5W charger despite delivering up to 20W of fast-charging power. It uses a stacked design with custom magnetic components, letting Anker shrink the internal parts down to a compact 29.5 x 29.5 x 30mm cube without sacrificing charging speed. The single USB-C port outputs 5V/3A or 9V/2.22A, automatically switching into fast-charging mode on supported iPhones and other USB-C devices as soon as it’s connected. It covers a broad range of Apple devices from iPhone 8 through 14, several iPad models, AirPods, and Apple Watch, along with select Samsung Galaxy and Google Pixel phones. The charger also handles Nintendo Switch charging, though it doesn’t support “Charge-and-Play” while docked in TV mode.

Best Suited For
- iPhone 8 through 14 owners who want a compact charger that automatically engages fast charging without extra setup
- Buyers with older or mid-range Samsung and Pixel phones, since compatibility extends to models like the Galaxy S10 series and Pixel 3/4/5, though newer Super Fast Charging-capable Galaxy models won’t reach their fastest speeds
- Travelers and minimalists wanting the smallest possible 20W charger to save space in a bag or on a nightstand
Recommended Action: Note that charging speed slows noticeably after 50% battery, which is a normal safety behavior for lithium batteries rather than a fault with the charger — factor this into how long a full charge actually takes.
