Performance & 140W Ultra-Fast Charging

The PD 3.1 Advantage

The 140W max output of the **Anker 737 Power Bank** is a direct result of supporting the **USB PD 3.1 Extended Power Range (EPR)** standard. This allows it to charge a compatible laptop, like a 16-inch MacBook Pro, from 0% to 50% in an astonishingly short time—often under **30 minutes**. This level of speed is almost identical to using the laptop’s original wall charger, making it a true performance replacement on the road.

Total Shared Output

When charging multiple devices (e.g., a laptop, phone, and earbuds), the power bank intelligently manages the total 140W output. It can, for instance, deliver 100W to the laptop while simultaneously providing 40W split between the smartphone and tablet, ensuring all three devices receive optimized fast charging without throttling the laptop’s primary charge speed significantly.

Deep Dive: 24000mAh Capacity Analysis

The 24,000mAh capacity (90 Wh) is the sweet spot for maximizing power reserves while remaining compliant with airline carry-on regulations. This capacity allows for:

• **Smartphones:** 5 full charges (iPhone 15 Pro Max, Galaxy S24 Ultra).
• **Tablets:** 1.5 to 2 full charges (iPad Pro 11-inch).
• **High-Wattage Laptops:** Approximately 0.8 full charge for a 16-inch MacBook Pro, providing crucial hours of extended use during travel or long meetings.

Recharge Speed and 140W Input
