The Anker 737 Power Bank Review: Is This the Ultimate Portable Power Solution?

How many times has this happened to you?

You’re in your flow state, cranking out work at a coffee shop. Your deadline is in an hour. You glance at your MacBook’s menu bar and see that dreaded red battery icon. 7%. Panic sets in. You scramble for a seat near an outlet, but they’re all taken. Your productivity—and your peace of mind—vanishes in an instant.

As a remote worker and frequent traveler, this was my reality for years. I’ve owned more “miracle” power banks than I can count, only to be let down by sluggish charging, insufficient capacity, or bulky designs that never left my drawer.

That’s why I was so intrigued by the Anker 737 Power Bank (PowerCore 24K). It promises not just to top up your phone, but to fully charge a laptop—all while sporting a brilliant digital display.

I’ve been using it as my daily driver for a month. Is it worth the investment, or is it just another overhyped gadget? Let’s break it down.

First Impressions: A Premium, “Get-Stuff-Done” Feel

Right out of the box, the Anker 737 feels different. It has a substantial, weighty feel that screams quality, not cheap plastic. The dark grey, textured finish provides a great grip, and the form factor is surprisingly compact for its massive 24,000mAh capacity. It fits comfortably in a laptop sleeve or backpack pocket.

But the star of the show is the smart digital display. Before you even plug it in, you know exactly how much power you have left. No more guessing games with blinking LED lights.

Key Features & Real-World Performance

This is where the Anker 737 truly shines. It’s packed with cutting-edge technology that justifies its price tag.

• GaNPrime™ Technology and 140W Output: This is a game-changer. Unlike older power banks, the GaN (Gallium Nitride) design allows for more power in a smaller space with greater efficiency. The 140W output means it can charge a 16-inch MacBook Pro at full speed. In my testing, it took my MacBook Air from 15% to 80% in just over an hour while I continued working.

• Massive 24,000mAh Capacity: The numbers are impressive, but what does it mean? In practical terms:

  • ~2.5 full charges for a 16” MacBook Pro

  • ~5 full charges for an iPhone 15

  • ~10 full charges for Galaxy Buds
    I was able to get through a full 3-day workcation, charging my laptop, phone, and earbuds daily, without needing a wall outlet once.

• 3-Port Versatility: Two USB-C ports and one USB-A port mean you can charge almost any combination of devices simultaneously. I regularly charged my laptop, iPhone, and Kindle all at once with no noticeable drop in charging speed.

• The Brilliant Digital Display: This might seem like a gimmick, but it’s incredibly useful. It shows the exact battery percentage remaining, the current input/output wattage, and even the time remaining for a full charge. It eliminates all the anxiety of not knowing your power status.

Who Is This For? (The Perfect User)

The Anker 737 isn’t for everyone. If you just need a tiny battery for an emergency phone charge, this is overkill.

It’s PERFECT for:

• Digital Nomads & Remote Workers: Work from anywhere without outlet anxiety.

• Frequent Travelers: Power through long flights, layovers, and hotel rooms with limited outlets.

• Students: Be the hero in the library during finals week.

• Content Creators & Photographers: Keep your laptop, camera batteries, and accessories powered during all-day shoots.

• Anyone who values preparedness: For peace of mind during power outages or busy days on the go.

The Only Downsides (Keeping It Honest)

No product is perfect. Here’s what you should know:

• Price: This is a premium product with a premium price. You’re investing in top-tier performance and reliability.

• Weight & Size: At about 1.5 lbs, it has a noticeable heft. It’s designed for a backpack, not a pants pocket.

• The Cable Isn’t Included: For a device capable of 140W charging, you’ll need to buy a compatible high-wattage USB-C cable separately, which is a slight annoyance.

Final Verdict: Is the Anker 737 Power Bank Worth It?

Absolutely, yes.

After a month of rigorous use, the Anker 737 has fundamentally changed how I work and travel. The anxiety of finding an outlet is gone. I’m more productive because I’m not worried about my device’s battery life.

While the initial cost is higher than basic power banks, you’re paying for:

1. The ability to charge a laptop.

2. Blazing-fast charging speeds.

3. The invaluable digital display.

4. The reliability of the Anker brand.

It’s not an expense; it’s an investment in uninterrupted productivity and peace of mind. For anyone whose livelihood or lifestyle depends on having reliable power, the Anker 737 is, without a doubt, the best power bank I’ve ever used.
