Quick summary:
✅ Makes sense if you need power for a laptop on your travels and also a power bank that you are allowed to take on an airplane.
⚠️ Consider that the 25,000 mAh (90 Wh) capacity is smaller than “giant” power banks, and power distribution can be a bit finicky when charging multiple devices.
💡 For 2,099 CZK you get 200W performance, two 100W USB-C ports, and a TFT display, plus a low complaint rate of 2.05%.

Why this power bank is interesting

This UGREEN power bank solves exactly what large 50,000mAh models cannot: high performance and the ability to take it on an airplane. Thanks to a total of 200 W and two 100W USB-C ports, it can charge two laptops simultaneously or quickly recharge a phone. The 25,000 mAh (90 Wh) capacity meets the limit for air travel, so you can take it on board without worries. And all this with a weight of 609 g and a slim columnar design that fits into a bag. Now, moreover, for 2,099 CZK.

Key parameters explained in plain language

The core is PD 3.1 technology with up to 200 W of power, support for USB-C PD, Qualcomm QC 3.0, and Huawei protocol, and three outputs (2× USB-C, 1× USB-A). Each of the USB-C ports can handle up to 100 W, so you can charge a MacBook Pro 16″ to 56% in half an hour. According to the manufacturer, the power bank will charge an iPhone 15 about 5.2 times, a Galaxy S23 Ultra 3.6 times, and a MacBook Pro 16″ approximately 1.3 times. It also features a clear TFT display showing voltage, current, and wattage in real-time, and 13 levels of protection.

Practical aspects: ports, charging, packaging

The power bank supports pass-through charging, meaning it can charge itself while simultaneously powering a connected device. A full charge from zero to 100% takes approximately two hours according to users (input up to 65 W). The package includes a USB-C to USB-C cable and a protective pouch. According to reviews, it does not overheat during charging and remains rather lukewarm. For small electronics (watches, headphones), there is also a special mode for small devices.

What users say

On Alza, the power bank has a rating of 4.9 out of 5 from 26 reviews and a low complaint rate of 2.05%. Users most praise the real 200W performance (powering two laptops), airplane approval, and the detailed TFT display. One user measured a usable capacity of around 85%, which is a good value for power banks. However, there are also criticisms: power distribution among multiple devices can be finicky (when another device is connected, power is redistributed; disconnecting and reconnecting cables helps) and the strap and pouch are not of the highest quality – one user’s power bank fell due to a loose strap.

When it doesn’t make sense

If you want as many charges as possible for the least amount of money and don’t need a power bank for an airplane, opt for a cheaper 50,000mAh model – it will offer more energy, albeit at the cost of weight and a ban on board. Similarly, if you only need to occasionally charge your phone, 200W performance is unnecessary, and a cheaper 20,000mAh power bank will suffice. And if you plan to continuously power two demanding devices at once, be aware that power distribution may not always be perfectly smooth.

Verdict: who it’s worth it for

For 2,099 CZK with code ALZADNY30, the UGREEN 25000mAh 200W is one of the most versatile power banks for travel and work. It combines high 200W performance with a decent capacity, and can also be taken on board an airplane. Minor compromises in the form of finicky power distribution and a lower-quality strap are not critical. For anyone who charges a laptop on the go and wants a power bank for air travel, it’s an excellent choice.
