Anker 737 PowerCore 24K Product Review, A High-Capacity Powerhouse for Heavy Users

If you’re always on the go and need a reliable portable charger to keep your devices powered, the Anker 737 PowerCore 24K is one of the best options available. With a massive 24,000mAh capacity, 140W fast charging, and a sleek yet durable design, this power bank is built for professionals, travelers, and tech enthusiasts who need serious battery backup.

In this review, we’ll break down its key features, performance, pros and cons, and compare it with other high-capacity power banks to help you decide if it’s the right choice for you.

Key Features of the Anker 737 PowerCore 24K

1. Massive 24,000mAh Capacity

With 88.8Wh of power, the Anker 737 can charge:

• A MacBook Pro 14″ (2023) 1.5 times

• An iPhone 15 Pro 4-5 times

• A Samsung Galaxy S23 Ultra 4-5 times

• A Nintendo Switch 3-4 times

This makes it perfect for long trips, workdays away from an outlet, or emergencies.

2. 140W Ultra-Fast Charging

One of the fastest charging speeds in a portable charger, the 140W output can:

• Charge a MacBook Pro 16″ from 0% to 56% in just 30 minutes

• Refill an iPhone 15 Pro to 50% in ~15 minutes

• Supports Power Delivery 3.1 (PD 3.1) for future-proof compatibility

3. Smart Digital Display

Unlike most power banks, the 737 PowerCore 24K has a built-in screen that shows:

• Remaining battery percentage (in 1% increments)

• Input/output wattage (so you know charging speeds in real-time)

• Estimated time remaining for charging/discharging

This is incredibly useful for monitoring power usage.

4. Triple-Port Versatility (2x USB-C, 1x USB-A)

• USB-C1 (140W Max Output) – Best for laptops and fast-charging phones

• USB-C2 (60W Max Output) – Great for secondary devices

• USB-A (18W Max Output) – For older devices like wireless earbuds

You can charge three devices simultaneously without slowdowns.

5. Premium Build & Portability

• Sleek, grippy exterior with a travel-friendly form factor

• Slightly heavier (1.5 lbs) due to the high capacity, but still manageable

• Airplane-safe (under 100Wh per battery cell)

Performance & Real-World Use

Charging Speed Tests

Battery Life & Efficiency

• Efficiency: Delivers about 85-90% of its rated capacity (typical for high-wattage power banks).

Who Is It Best For?

✔ Frequent travelers needing multiple device charges
✔ Digital nomads & professionals using power-hungry laptops
✔ Gamers who want extended playtime for the Steam Deck/Switch
✔ Tech enthusiasts who love high-speed charging
