CUKTECH 45W Power Bank Review: The Best Budget Power Bank Under $30

As someone who has reviewed countless power banks, including the premium Anker 737, Anker Prime, CUKTECH 20 and Sharge Storm 2, I’ve seen it all—sleek designs, fancy displays, and impressive charging speeds. However, these features often come with a hefty price tag. That’s why the CUKTECH 45W Power Bank caught my attention.

At under $30, this power bank delivers exceptional value, making it a standout choice for budget-conscious users who still want reliability, portability, and performance. While it may not cater to extreme fast-charging enthusiasts, its 20,000mAh capacity and built-in USB-C cable make it the perfect companion for everyday users who value convenience and affordability.

We Don't Like

Charging Speed: While 45W charging is decent, it is not the fastest—so it’s not ideal for those seeking extremely fast charging or fast charging while charging multiple devices simultaneously.
Bulkier Size: The 20,000mAh capacity makes it a bit bulkier compared to smaller power banks, which might be an issue for people looking for an ultra-portable option.
No Wireless Charging: This power bank does not support wireless charging.

My Power Bank Journey: Why the CUKTECH Stands Out

Over the years, I’ve tested many power banks, and while I love the fancy designs and advanced features of models like the Sharge Storm 2, I’ve found that these extras are often unnecessary for most users. Complex displays showing battery details or intricate functions may look cool, but they tend to consume more capacity and add bulk without offering much practical value.

I’ve also encountered a recurring problem: losing cables. As someone who often misplaces things, I’ve had power banks with me but no cable to charge my devices—a frustrating experience, especially during travel or emergencies. That’s why the built-in USB-C cable on the CUKTECH 45W Power Bank is a game-changer for me.

Another challenge I’ve faced is the small capacity of certain power banks. With two phones to charge daily, smaller capacity models don’t last long enough. The CUKTECH’s 20,000mAh capacity solves this problem, ensuring I have enough power for multiple charges without worrying about running out of juice.

What Makes the CUKTECH 45W Power Bank Exceptional

1. Unbeatable Price

Let’s start with the most impressive aspect: price. At less than $30, the CUKTECH 45W Power Bank delivers features typically found in products costing twice as much. While premium models like the Anker 737 and Sharge Storm 2 are excellent, they come with price tags that can exceed $100.

For budget-conscious buyers, the CUKTECH is an incredible deal that doesn’t compromise on essential features like capacity, portability, and charging speed.

2. Massive 20,000mAh Capacity

With its 20,000mAh capacity, this power bank is built to handle multiple charges for a variety of devices. Here’s what you can expect:

iPhone 15: Up to 4.1 full charges
Samsung Galaxy S24 Ultra: Up to 2.9 full charges
iPad Air: About 1.9 charges
MacBook Air (A2337): 1.2 charges

This makes it an ideal choice for travelers, commuters, and anyone who needs a reliable backup power source. Whether you’re working long hours, traveling across time zones, or preparing for emergencies, the CUKTECH ensures your devices stay powered up.

3. Built-In USB-C Cable

One of my favorite features is the built-in USB-C cable. As someone who frequently forgets to bring charging cables, this feature has saved me from countless headaches.

The cable is durable, tested to withstand over 10,000 uses, and even doubles as a carrying strap. This small but thoughtful design element adds a layer of convenience that’s rare to find in a power bank at this price point.

4. 45W Charging: Reliable but Not the Fastest

The CUKTECH offers 45W maximum output, which is fast enough for most users but may not satisfy those who need extreme fast charging or want to charge multiple devices simultaneously at high speeds.

Here’s what it can do:

Charge a Samsung Galaxy S24 Ultra to 50% in 20 minutes
Power up a MacBook Air (A2337) to 42% in just 30 minutes

However, if you’re charging multiple devices at once, the speed will slow down. For example, charging two or three devices simultaneously may result in moderate charging speeds rather than the blazing-fast performance some high-end power banks offer.

That said, at less than $30, the CUKTECH strikes a good balance between price and performance, making it a solid choice for everyday users who don’t need ultra-fast speeds.

5. Multi-Device Charging

The power bank is equipped with:

2 USB-C ports (45W PD)
1 USB-A port (18W QC)

This means you can charge up to three devices at once, which is handy for anyone carrying multiple gadgets like smartphones, tablets, or wireless earbuds.

6. Compact and Travel-Friendly Design

At just 5.76 inches in length, the CUKTECH is small enough to fit in your backpack or even a pocket. Its lightweight design and built-in cable make it a practical choice for travelers who want to pack light without sacrificing charging capacity.

7. Safety Certified

The CUKTECH 45W Power Bank meets multiple safety certifications, including UL, CE, CB, and FCC, ensuring a safer charging experience for your devices.
