The well-equipped Anker power bank can now be yours for 1,553 CZK. All it takes is one thing

Power banks with enough power for a laptop are usually not cheap, so it’s worth paying attention when a good option appears with a price several hundred crowns lower. The Anker Power Bank 25K with 165W output costs 1,533 CZK with AlzaPlus+ membership instead of the regular 2,190 CZK. This model is also currently being tested in our editorial office, so in addition to its parameters, we will also offer you our first impressions from real-world use.

Quick summary:
✅ It makes sense if you need to charge both your laptop and phone on the go and want a 25,000 mAh capacity with a display and integrated cables.
⚠️ Consider if you mind the weight of 595 g and if you will actually use AlzaPlus+, because that’s how you get to 1,533 CZK.
💡 For 1,533 CZK with AlzaPlus+ you get a lot of power and capacity, but 165 W is a peak value for two ports, not for every device simultaneously.

Why this power bank is interesting

This Anker power bank is primarily aimed at laptop owners, offering enough energy and power to charge a laptop, not just a phone. The combination of 25,000 mAh and up to 165 W output places it among the more robust pieces, but at the same time, it can power several devices simultaneously thanks to its four outputs. It is precisely the member price of 1,533 CZK with AlzaPlus+ that makes it a more interesting purchase than you would expect for equipment of this type.

You get the price of 1,533 CZK through AlzaPlus+ membership (299 CZK annually, or 59 CZK monthly), which, in addition to the discount, also provides free delivery for the entire year. Without membership, the regular price is 2,190 CZK.

Key parameters explained in plain language

A capacity of 25,000 mAh is enough to charge your phone several times and add a decent amount of battery to your laptop when away from an outlet. Connectivity is handled by a trio of USB-C ports and one USB-A port, with two integrated USB-C cables, including a retractable one, so you don’t have to carry your own cables when traveling. The USB-A port will be appreciated by anyone still using older accessories.

Regarding output, it’s good to understand one detail. The total of 165 W is a peak value when charging two devices; when three to four devices are connected, the power bank delivers a maximum of around 130 W, with up to 100 W flowing through a single USB-C port. In practice, this is sufficient for fast charging of both a laptop and a phone. Charging is managed by Anker Power IQ 3.0 technology along with support for USB Power Delivery and Qualcomm Quick Charge 3.0.

Practical aspects: our first impressions from testing

We have the model in our editorial office and are preparing a full review for it, so here are just a few quick observations. We really like the color display, which shows power, percentage, and remaining time during charging, complemented by the cell temperature and number of charging cycles — this will please more technically-minded users. The retractable USB-C cable is also practical, ensuring you always have a connection at hand.

We can also confirm the manufacturer’s promised charge to 30% in approximately 20 minutes; the charging power initially jumped to 94 W, but after a few minutes, it decreased to about 52 W due to higher cell temperature, which is to be expected with such powerful devices. You also have to factor in the weight of 595 g — it’s not an ideal companion for short walks around the city. Additionally, the second, fabric-braided integrated cable might be a bit cumbersome for some when traveling.

Ratings are decent, over a thousand units sold

On Alza, the power bank has a rating of 4.5 out of 5, but so far from a small sample of 17 ratings and 8 reviews, so take it as an indication rather than a firm conclusion. 82% of customers recommend the model, and the return rate is at a low level of 0.52%, with over 1,000 units sold.

When it doesn’t make sense

If you don’t charge a laptop and just need to top up your phone or headphones, this power bank is unnecessarily large, heavy, and powerful — a lighter 10,000 mAh model will fit better in your pocket. Similarly, if you don’t want to pay for AlzaPlus+ membership, the 1,533 CZK price doesn’t apply to you, and at the regular 2,190 CZK, competition increases. And for those looking for the lowest possible weight for trips, opt for a more compact piece, because you’ll notice 595 g on your back.

Verdict: who it’s worth it for

The Anker Power Bank 25K is a sensible choice for laptop owners who want ample capacity, high power, and a smart display in one unit. With AlzaPlus+ membership for 1,533 CZK, it is, according to our verification, currently the best offer for this model in the Czech Republic, and the features match: 165 W, integrated cables, and a clear screen. Be aware of the higher weight of 595 g and that the peak 165 W applies to two ports. Those who can accept these compromises and genuinely use AlzaPlus+ will get a lot of power for 1,533 CZK; we will provide a detailed verdict in an upcoming review.

When choosing a power bank, do you prioritize laptop power or the lowest possible weight for travel?
