Product Details

45W Full Load Fast Charging – Perfect for iPhone 17 & More

The Anker Nano 45W GaN Charger delivers full 45W output via its single USB‑C port. Real‑world performance with iPhone 17 series:

The charger supports max 45W output; iPhone 17 series tested max 39W. Actual charging time may vary by scenario.

For larger devices like MacBook Air or iPad Pro, the charger provides up to 45W – enough for rapid top‑ups and sustained power.

Smart Digital Display – See Your Charging Speed in Real Time

The built‑in screen is the standout feature. It shows:

• Wattage output – e.g., 39W, 20W, 8W

• Device recognition – e.g., “Charging iPhone 17 Pro Max”

• Battery level indication – e.g., “65%”

No more guessing whether your charger is fast‑charging. The transparent display lets you monitor performance at a glance.

3‑Stage AI Power Matching – Protects Battery Health

Anker’s intelligent algorithm dynamically adjusts charging power based on your device’s current battery level:

Battery Level	Charging Mode	Power Output	Benefit
0‑15%	Ultra‑fast charging	39W	Get power quickly when battery is critically low
15‑50%	Fast charging	20W	Balanced speed for daily top‑ups
50‑85%	Trickle charging	8W	Reduces heat, extends battery lifespan
85‑100%	Maintenance mode	Minimal	Prevents overcharging, preserves long‑term health

This smart matching ensures your device charges efficiently without unnecessary stress on the battery.

Recognizes iPhone Models – Exclusive Charging Curves

The Anker Nano 45W communicates with your iPhone to deliver the optimal charging profile. The display confirms the device model, so you know the charger has identified your phone correctly. Safe, worry‑free, and optimized for Apple’s latest iPhones.

GaN Technology – Small Size, Big Performance

Gallium Nitride (GaN) is the next‑generation semiconductor material that replaces traditional silicon. Benefits:

• Smaller charger size – 45W power in a body smaller than many 20W chargers

• Less heat generation – GaN is more efficient, so less energy is lost as heat

• Higher energy efficiency – Faster charging with less power waste

• Smoother charging experience – Stable power delivery without voltage fluctuations

Ultra‑Compact & Travel‑Ready – 75g Pocket Size

The Anker Nano 45W is designed for portability:

• Dimensions: 34 × 35.5 × 40 mm – smaller than a golf ball

• Weight: 75g – lighter than a deck of cards

• Foldable plug? Not specified but likely fixed prongs (US plug)

Slip it into a pocket, laptop bag, or even a small purse. Perfect for daily commutes, business trips, or international travel (100‑240V in
