Anker 737 Power Bank (PowerCore 24K)

When Anker announced the 737 Power Bank with 140W output, the tech community took notice. This isn’t just another power bank—it’s a portable power station that can keep your entire tech ecosystem running. We spent three weeks testing this premium device in real-world scenarios, and here’s what we found.

First Impressions

The Anker 737 arrives in premium packaging that sets the tone for the product inside. The power bank itself feels substantial—there’s no getting around the 1.4-pound weight—but the build quality immediately justifies the heft.

The soft-touch finish feels luxurious and provides excellent grip, while the 1.8-inch color LCD adds a level of sophistication we haven’t seen in consumer power banks. The display shows remaining capacity, output/input wattage for each port, and even estimated time to full charge or depletion.

Performance That Delivers

Laptop Charging

This is where the 737 truly shines. The 100W USB-C output can charge virtually any USB-C laptop at full speed. We tested with a MacBook Pro 16-inch, Dell XPS 15, and Lenovo ThinkPad X1 Carbon—all charged at their maximum rates.

In our laptop test:

• MacBook Pro 16”: 0-50% in 40 minutes
• Dell XPS 15: 0-50% in 38 minutes
• Full charge time: approximately 90 minutes

Multi-Device Charging

The intelligent power distribution works beautifully. When all three ports are in use, the total 140W is dynamically allocated. In our three-device test (laptop + tablet + phone), each device received sufficient power for rapid charging.

Capacity Test

The 24,000mAh capacity is genuine—we measured 23,850mAh at 3.7V, which translates to approximately:

• 5 full iPhone 15 Pro charges
• 2 full Samsung Galaxy S24 Ultra charges
• 1.5 full MacBook Air M3 charges
• 4 full iPad Pro 12.9” charges

Recharge Speed

The 65W input is equally impressive. Using a compatible charger (not included), the 737 fully recharges in just 2.5 hours—a remarkable achievement for this capacity.

Build Quality

Anker’s reputation for durability holds true here. The ports are reinforced, the casing feels drop-resistant, and the premium cells should maintain 80% capacity after 500+ cycles. The 18-month warranty provides additional peace of mind.

The LCD display isn’t just for show—it provides genuinely useful information:

• Real-time wattage per port
• Temperature readings
• Estimated time remaining
• Cycle count

What Could Be Better

The 737 isn’t perfect. At $150, it’s a significant investment. Some users might prefer the lighter, more portable Anker 735 (20,000mAh, 65W) at a lower price point.

The size also means this is a bag power bank, not a pocket companion. For commuters or travelers with a backpack, this isn’t an issue, but those seeking ultra-portability should look elsewhere.

The Competition

Compared to the closest alternatives:

Feature	Anker 737	Zendure SuperTank Pro	EcoFlow River Pro
Capacity	24,000mAh	26,800mAh	72,000mAh
Max Output	140W	138W	600W
Display	Color LCD	LED	LED
Weight	1.4 lbs	1.5 lbs	16 lbs

The Anker wins on output power density and user interface.

Final Verdict

The Anker 737 Power Bank represents the pinnacle of consumer portable charging technology. It’s expensive, heavy, and oversized—but if you need serious power delivery on the go, nothing else comes close.

Who should buy this:

• Professionals with multiple high-power devices
• Travelers who need laptop charging capability
• Photographers/videographers with battery-hungry equipment
• Anyone who demands the absolute best performance

Who should look elsewhere:

• Casual users with only phones/tablets
• Those prioritizing weight and portability
• Budget-conscious consumers

At $150, the Anker 737 is a premium product for premium users. If you fall into that category, you won’t be disappointed.
