Great power bank for laptop charging discounted by 30%. It impresses not only with its excellent performance

Looking for a power bank suitable for charging a laptop? Ideally, such models offer a capacity above 20,000 mAh and power exceeding the 100W mark. The UGREEN 25000mAh PD 145W, which has now dropped from 2,399 Kč to 1,679 Kč on Alza, meets both these conditions. Users in reviews rate it predominantly positively and it has a total of three outputs.

Quick summary:
✅ Makes sense if you want one power bank for your phone, tablet, and laptop and will utilize 140W USB-C charging.
⚠️ Consider if you expect a hundred percent match with the declared capacity or if you mind the weight over 600 g.
💡 For 1,679 Kč, it offers a strong performance/price ratio, even though it was slightly cheaper in a previous sale.

Why this power bank is interesting

Most power banks of this size stop at 22.5 W or 100 W and are insufficient for truly recharging a more powerful laptop. UGREEN 25000mAh PD 145W aims higher: the main USB-C port delivers up to 140 W, and the total output across all connectors is 145 W. In practice, this means it can power laptops where a standard 65W power bank would just helplessly blink. One reviewer describes that their Asus Zenbook with a 96Wh battery charged from 10 to 90% directly while working.

Originally, the model sold for 2,399 Kč, and even outside of deeper sales, it was among the more expensive pieces. The drop to 1,679 Kč moves it into a price range where it can realistically be considered a replacement for a standalone backpack charger. Fairly, we add that it cost 1,559 Kč in a sale a month ago, so the current price is not historically the lowest, but it is still a significant drop compared to the standard 2,399 Kč.

Key parameters in plain language

The capacity is 25,000 mAh, which corresponds to approximately 92.5 Wh of energy. Due to voltage conversion losses, about 80 Wh is actually usable, so you can charge a phone with a standard battery three to four times, not “infinitely” as marketing sometimes suggests. The power bank offers three ports simultaneously: two USB-C (140 W and 65 W) and one USB-A (22.5 W). It supports PD 3.1/3.0, QC 3.0, and PPS, making it compatible with phones, tablets, and laptops.

A practical detail often overlooked: with its 92.5 Wh, the model is below the 100 Wh limit, so you can take it on an airplane in your carry-on luggage without special airline approval. Power banks over 100 Wh are usually a problem, but this one is not.

Practical aspects: ports, weight, charging

On the front is an information display that shows battery status and power. The power bank supports pass-through charging (it charges itself while simultaneously powering a connected device), even though Alza doesn’t mention it in the description. However, be aware of one limitation: the main 100W port serves as both input and output simultaneously, so you charge the power bank and draw power from it using the same connector.

Expect a weight of around 620 g. For its performance and capacity, this is to be expected, but you won’t put it in a shirt pocket; it’s more of a permanent resident of a backpack. The good news is the low complaint rate of 2.49% and 85% of customers who recommend it, which is not a given for charging electronics.

What users say

On Alza, the power bank has a rating of 4.5 out of 5, but there are only 15 written reviews (47 ratings in total), so consider the sample more as indicative. People most often praise its really high performance and ability to charge demanding devices: one user managed to charge a Steam Deck OLED, phone, and tablet simultaneously, while another uses it as a power source for a second monitor for their laptop.

Criticism mainly revolves around two things. The first is the real capacity, which according to several reviews does not match the declared 25,000 mAh; one user states it has 10% less than their three-year-old AlzaPower 20000mAh. The second complaint targets the display, which sometimes freezes for tens of minutes, and one reviewer described it as a “random number generator.” There was also a mention of faster self-discharge and material that wears out sooner.

When it doesn’t make sense

If you just want a light pocket power bank for your phone, this model is unnecessarily large, heavy, and expensive; a model up to 10,000 mAh for a few hundred crowns will suffice. It also won’t suit people who insist on an exact match between real and declared capacity, as this is the most frequent complaint in reviews. And if you mind a display that occasionally shows unreliable values, expect this to be a weak point here.

Verdict: who it’s worth it for

The main reason to buy is its 145 W power and ability to charge a laptop, not its record capacity. If you need one device that powers your phone, tablet, and work laptop and you utilize the 140W USB-C port, then for 1,679 Kč, it’s a reasonable choice with a low complaint rate. However, take two things seriously: the real capacity is lower than the number promises, and in a previous sale, the power bank could be bought for 1,559 Kč, so if you’re not in a hurry, it might be worth waiting for a return to a lower price.

Do you also charge your laptop from a power bank, or is it purely for your phone?
