What Is the Anker 737 Power Bank? Tech Specs and Features Explained

The Anker 737 Power Bank (PowerCore 24K/Anker Prime) is one of the best portable chargers for laptops, designed for users who need more than just a phone charge. It stands out among Anker’s lineup and is frequently recommended as one of the best Anker power banks in 2025—especially for students and mobile professionals.

Key Features: Build Quality, Capacity, and Portability

• Battery: 24,000mAh—enough to fully recharge large laptops like the MacBook Pro, plus phones and tablets
• Power Output: Supports USB-C Power Delivery 3.1 at up to 140W, which matches even the latest Apple laptops’ max input
• Technology: Utilizes Anker’s PowerIQ 3.0 smart-detection and Power Delivery (PD) for device-optimized charging speeds
• Design: Durable, travel-friendly build (bigger than a phone charger, but fits easily in bags and backpacks)
• Pass Through Charging: Charge devices and the power bank at the same time

Thanks to its high capacity, wide voltage support, and rugged design, the Anker 737 consistently tops lists for best portable chargers for students and professionals who depend on all-day MacBook power.

What Is Fast Charging for MacBook Pro? Understanding USB-C PD and Speed Requirements

When users ask about "fast charging MacBook Pro," they want real speed—getting the maximum charge rate so they spend less time plugged in. Fast charging for MacBook Pro means meeting the specific power requirements for each model, mainly over the USB-C PD (Power Delivery) standard.

What Does “Fast Charging” Mean for MacBook Pro Laptops?

• 13-inch MacBook Pro/MacBook Air: Up to 67W
• 14-inch MacBook Pro: Up to 96W or 140W (configuration dependent)
• 16-inch MacBook Pro (2021 and later): Up to 140W for true fast charge

A USB-C PD power bank or PD charger for MacBook Pro must meet or exceed these wattages to unlock fast charging. Ordinary USB-C charging—without PD support or with a lower wattage—will result in much slower charge times.

USB Power Delivery (PD 3.1) Explained

• USB-C PD 3.1 supports up to 240W, but the key milestone for MacBooks is 140W (the max for the latest 16-inch model).
• For fast, safe charging, use a cable rated for 140W or more (often labeled “E-Marked” or “PD 3.1”).

Understanding your MacBook Pro’s charging requirements ensures you avoid underpowered chargers or slow-charge scenarios.

Anker 737 Power Bank Compatibility with MacBook Pro — The Definitive Answer

Short answer: The Anker 737 Power Bank is fully compatible with all MacBook Pro models, including the newest 14-inch and 16-inch versions that support up to 140W fast charging.

Which MacBook Pro Models Are Compatible?

• 16-inch MacBook Pro (2021+): Full-speed 140W charging—matches Apple’s wall adapter, provided your cable is rated for 140W/PD 3.1.
• 14-inch MacBook Pro (2021+): Supports up to 96W or 140W, depending on the configuration.
• 13-inch MacBook Pro & Air: Supports up to their respective maximums (typically up to 67W).

How to Confirm Compatibility and Fast Charging

1. Check Your MacBook’s Maximum Power Input: Look at your MacBook’s original charger or Apple’s specs.
2. Choose a High-Quality USB-C Cable: Look for cables that are specifically rated for 140W/PD 3.1 and E-Marked.
3. Plug In and Check: Connect your MacBook Pro to the Anker 737’s USB-C output. macOS will indicate "Charging on AC Power" or, on newer OS versions, show “Fast Charging.”

User Insight: Recent buyer reviews and Reddit reports confirm that the Anker 737 enables fast charging as long as you use a compliant cable. Community consensus and real-world feedback are clear—this power bank delivers as promised.

Is Anker Good for MacBook Pro? Absolutely. Anker’s reputation for reliability, safety, and innovation makes the 737 a popular alternative to Apple’s official (often pricier) chargers—especially for those who want a portable solution.

Real-World Fast Charging Results: What You Can Expect with the Anker 737

Charging Speed & Real-World Testing

Extensive user reviews and tech community feedback agree on charging speeds close to Apple's own adapters:

• 16-inch MacBook Pro: Around 50% charge in 40 minutes, full charge in 1.5 hours (just like Apple’s official 140W adapter)
• 14-inch MacBook Pro: Reaches full speed according to model specs—matches official wall chargers
• 13-inch MacBook Pro/Air: Delivers up to their top supported charge rates

How Many MacBook Charges from One Cycle?

• 16-inch MacBook Pro: About 1 full charge (from empty)
• 14-inch MacBook Pro/MacBook Air: Around 1.3 full charges per cycle
• Phones like iPhone 15: Up to 4–5 full charges

Actual results vary based on device usage while charging, battery age, and settings.

Charging Multiple Devices: What Happens?

• If you connect more than one device, the maximum wattage is divided, so your MacBook won’t get 140W.
• For best results, charge your MacBook alone.

Portable Power On The Go

The flexibility to work from coffee shops, airports, or even outdoors—without outlet anxiety—is a true game changer, as many Reddit users and reviewers point out.

Expert Tip: Always use a certified 140W USB-C cable (E-Marked/PD 3.1) to guarantee top speed. Even expensive devices will be underpowered by a low-rated cable.

Essential Setup: Cables, Accessories, and Maximizing Fast Charging Performance

Getting the most from the Anker 737 Power Bank (and your MacBook Pro) means paying attention to your cables and accessories.

Cables Matter—A Lot

• For Maximum Speed: Only certified 140W (or higher, e.g., 240W) USB-C PD 3.1 cables will enable full fast charging.
• Avoid Generic Cables: Older or cheap cables often lack the proper internal wiring, limiting safe wattage.

Accessory Safety and Reliability

If you want a replacement, safe charger that matches the Apple charger for MacBook Pro but costs less, consider a high-quality USB-C to MagSafe 3 cable or universal power brick.

• Use Certified Adapters and Accessories: Choose recognized brands for dongles, hubs, and MagSafe adapters.
• Refill Faster: Recharge your Anker 737 with a high-output PD wall charger (65W or more recommended).

Travel and Usage Tips

• Pack the Anker 737 in your carry-on (not checked luggage—required by airlines for all power banks).
• Keep your MacBook and at least 2 reliable, certified cables handy.
• If charging is slow, double-check for device sharing and try reseating the connection.

Troubleshooting: If your MacBook isn’t fast charging, check your cable and ensure no other devices are connected, then unplug/reconnect.

Frequently Asked Questions
