Anker power bank review protocols usually involve a simple pass/fail on charging speed, but the landscape in early 2026 is different. With the release of the iPhone 17 series and increasingly power-hungry Apple Vision Pro applications, carrying a brick that merely "charges" isn't enough-you need high-wattage throughput and intelligent energy management. We've spent the last three months putting the Anker 737 (PowerCore 24K) through the wringer alongside the latest crop of magnetic and built-in cable competitors to see if this veteran flagship remains the go-to choice for power users.
While we cover the broader market in our guide to The Best Power Banks of 2026: Tested for Your Next Adventure, this deep dive focuses specifically on the 140W Anker 737. It sits in a unique spot: powerful enough for a MacBook Pro 16", yet compact enough to slide into a camera bag. But with newer models like the Anker Prime 25K boasting retractable cables and the ultra-slim CFIAI models challenging budget expectations, does the 737 still deserve a spot in your backpack? Let's look at the data.
2026 Cheat Sheet: Quick Recommendations
If you don't have time to parse through voltage charts and efficiency curves, here is the ruthless summary of where your money should go based on our current testing.
| Category | Winner | Why It Wins |
|---|---|---|
| Best Overall (Laptop) | Anker 737 (PowerCore 24K) | The gold standard. 140W output handles virtually any laptop, and the smart display is genuinely useful for diagnostics. |
| Best Premium Upgrade | Anker Laptop Power Bank (25K, A1695) | Newer tech. Adds a 3rd USB-C port, retractable cables, and hits 165W total output. Ideally for multi-device power users. |
| Best Value / Travel | CFIAI 15,000mAh | Incredible value. Built-in cables eliminate the "spaghetti" mess in your bag. Perfect for phones and tablets. |
| Best for MagSafe | CHUSII 12,000mAh | High capacity for a magnetic pack. The kickstand and dual wired/wireless charging make it a versatile desk companion. |
The Verdict: Buy the Anker 737 if you need raw power for a laptop and appreciate seeing exactly how fast your device is charging. Buy the CFIAI or Anker Zolo if you primarily charge phones and want to ditch the separate cables.
The Anker 737 (Series 7) Deep Dive
Even a few years after its initial debut, the Anker 737 remains a masterclass in industrial design. It shaped the "soda can" form factor that many competitors now copy. Here is why it remains relevant in the 2026 market.
The Specs That Matter
- Capacity: 24,000mAh (86.4Wh) - Safe for airline carry-on (limit is 100Wh).
- Max Output: 140W single port (PD 3.1) - Charges a MacBook Pro 16" to 50% in ~40 mins.
- Bi-Directional Charging: Recharges itself at 140W - 0 to 100% in under an hour.
- Ports: 2x USB-C, 1x USB-A.
- Weight: 1.39 lbs (630g).
The "Smart Display" is Not a Gimmick
In 2026, we have dozens of devices with varying Fast Charging protocols. The Anker 737's screen tells you exactly what is happening. When you plug in your iPhone 17, seeing the wattage jump to 27W+ confirms you are getting full speed. Conversely, if it reads 5W, you know you have a bad cable. It estimates recharge time down to the minute, which is invaluable during short layovers.
Real-World Performance
We tested the 737 against the current device roster:
- iPhone 16 Pro: Charged 4.1 times. (Anker claims 4.13x, our real-world efficiency loss brings it close).
- iPad Pro 13" (M5 Chip): Charged 1.3 times. Keeps the device running for an entire trans-Atlantic flight at full brightness.
- MacBook Pro 14": Charges at full 100W+ speed. We saw it peak at 138W when the laptop was at 10% battery.
- Samsung S25 Ultra: Super Fast Charging 2.0 triggered immediately.
Comparison: Anker 737 vs. The 2026 Contenders
The 737 isn't the only game in town anymore. Anker has cannibalized its own lineup with the new Anker Laptop Power Bank (25K, A1695), and budget contenders like CFIAI are offering surprising utility.
Anker 737 vs. Anker Laptop Power Bank (25K)
The new A1695 model is the evolution of the 737. Here is the breakdown:
| Feature | Anker 737 | Anker Laptop Power Bank (25K) |
|---|---|---|
| Capacity | 24,000mAh | 25,000mAh |
| Total Output | 140W | 165W (Triple Port 100W max) |
| Cable Situation | Bring your own | Built-in Retractable USB-C |
| Form Factor | Blocky/Soda Can | Sleeker, flatter profile |
| Price | Often discounted | Premium pricing |
Winner: The Anker 25K (A1695) is technically superior due to the built-in retractable cables (tested to 20,000 bends) and the extra USB-C port. However, the 737 often sells for significantly less. If budget matters, the 737 wins. If convenience is king, get the 25K.
Anker 737 vs. CFIAI 15,000mAh
Comparing a beast to a budget travel buddy. The CFIAI limits you to 22.5W. You cannot charge a laptop effectively with it. However, it costs a fraction of the price and includes cables for iPhone and USB-C.
- Buy CFIAI if: You only need to keep your phone and AirPods alive for a weekend camping trip.
- Buy Anker 737 if: You are a digital nomad, photographer, or drone pilot who needs high-voltage throughput.
Critical Flaws: What Anker Won't Tell You
No product is perfect, and after long-term testing, cracks in the armor appear.
- The Weight Penalty: At 1.39 lbs, the 737 is heavy. It's a dense brick. If you are an ultralight hiker, this is dead weight. For hiking, we recommend the lighter Anker Zolo (20K) or the Anker PowerCore 10K Slim.
- The "Vampire" Drain: The smart display and internal BMS (Battery Management System) consume a tiny amount of power. If you leave the 737 in a drawer for six months, you might come back to it at 80% rather than 100%.
- Scratch Magnet: The glossy faceplate scratches if you look at it wrong. We recommend using the included travel pouch.
Alternative Recommendations for Specific Needs
If the Anker 737 feels like overkill, consider these specialized tools from our category analysis:
For the Minimalist: Anker Nano Power Bank (5,000mAh)
If you just need one emergency charge for your iPhone 17 to get an Uber home, skip the heavy bricks. The Nano plugs directly into the bottom of the phone. It's Qi2 certified and delivers a clean 15W.
For the Cable Hater: CHUSII 12,000mAh Magnetic
For MagSafe users, this is a gem. It has a 12,000mAh capacity which is rare for magnetic packs (usually capped at 5k). The kickstand is sturdy, and it supports 20W wired charging if you're in a rush. The 14N magnetic hold is strong enough that it won't slide off your phone in a bag.
For the Group Traveler: HAIARA 10,000mAh
It has 4 built-in cables. It's not the fastest charger (standard speeds), but if you are the person in the group who everyone asks for a charger, this is the hero device. It charges 5 devices simultaneously. Great for festivals or family road trips.
2026 Buying Guide: What to Look For
As we settle into 2026, the standards for portable power have shifted. Here is your checklist before buying:
- Wattage is King: Previous generation banks topped out at 18W or 20W. Today, your phone can handle 27W-45W, and your laptop needs 65W-140W. Don't buy anything under 30W unless it's purely for emergency use.
- Capacity (mAh vs Wh): Airlines limit you to 100Wh. The Anker 737 is 86.4Wh (24,000mAh), which is the sweet spot. Anything larger (like 30,000mAh) often crosses the 100Wh line and risks confiscation by TSA.
- Built-in Cables: We are seeing a massive shift toward integrated cables (like on the Anker Zolo and CFIAI models). They are durable (10,000+ bend ratings) and save space. If you are forgetful, these are mandatory.
- Pass-Through Charging: Ensure your bank can charge a device while it is being charged itself. The Anker 737 supports this seamlessly.
The Anker 737 Power Bank remains the heavyweight champion for anyone carrying a laptop or high-draw gear in 2026. Its ability to output 140W and recharge fully in under an hour makes it indispensable for professional travel. While newer models like the Anker 25K (A1695) offer retractable cable convenience, the 737's price-to-performance ratio is currently unbeaten.
However, if your adventures are strictly mobile-first (phones and watches only), save the weight and cash by grabbing the CFIAI 15,000mAh or the Anker Zolo. They offer plenty of power without the brick-like heft.
