The new power bank from Alza is on sale for the first time. It has a built-in USB-C cable and costs only 349 CZK

Are you looking for a thin power bank for travel or city use, for which you won’t have to carry a cable every time? AlzaPower City 10000mAh has now dropped from 499 CZK to 349 CZK with code ALZADNY30 – and this is its very first discount. It features an integrated USB-C cable and is primarily aimed at users who prioritize affordability over performance.

Quick summary:
✅ Makes sense if you want a thin and light power bank with a cable always at hand and a display showing the charge status.
⚠️ Consider that this is a new product with a small number of reviews and that 22.5 W applies only to one port, not all simultaneously.
💡 For 349 CZK you get 10,000 mAh from AlzaPower with a three-year warranty – for a newly discounted item for the first time, this is a decent entry point.

Why this power bank is interesting

This AlzaPower City power bank targets people who don’t want to carry a brick and appreciate having a charging cable always with them. The body measures only 15 mm, and the integrated USB-C cable with a curved tip also serves as a loop. For 349 CZK with code ALZADNY30, it’s one of the cheaper ways to get a thin power bank with a display from an established Czech brand – and for a model that’s discounted for the first time.

Key parameters in plain language

The capacity is 10,000 mAh (38.5 Wh), which realistically means about 1.5 to 2 full charges of a typical phone – due to voltage conversion losses, you’ll never get the full 10,000 mAh into a device. The power bank supports Power Delivery 3.0, Quick Charge 3.0, as well as protocols for Samsung and Huawei. But pay attention to the output: 22.5 W is offered only by the USB-A port, the USB-C port itself provides max. 20 W, the integrated cable 18 W, and when charging via all outputs simultaneously, the power drops to 15 W. For one phone, this is fine; don’t count on maximum speed for multiple devices.

Practical aspects: cable, ports, charging

The main advantage is the integrated cable directly in the body – you don’t have to look for a free USB-C cable, you just pull it out of the power bank. Although it’s only 18 cm, making it better suited for “pocket-to-pocket” charging than reaching a wall socket, it makes sense as a travel solution. In addition, there’s a classic USB-C and USB-A port, so you can charge up to three devices simultaneously. The Low Power Mode for headphones and watches is also useful, preventing the power bank from shutting down due to low current draw.

Charging the power bank itself takes approximately 3 hours (with at least an 18W charger), and the display shows the charge status in percentages. A nice bonus compared to competitors is the three-year warranty (36 months), which is one year more than the standard 24 months – although the battery itself is always considered a consumable item from a warranty perspective.

What users say

Caution is needed here: the power bank currently has a rating of 4.5 out of 5, but only from 6 customers and based on 3 reviews. This is too small a sample to draw conclusions about long-term reliability. While the return rate is low (0.46%), this is also based on a small number of units sold, as it’s a new product with 500+ sales. Consider this more as an indicative signal than a verified verdict from thousands of people.

When it doesn’t make sense

If you need a lot of capacity for several days without a power outlet, 10,000 mAh might not be enough, and a 20,000 mAh model would serve you better. Those who want maximum charging power for multiple devices simultaneously will hit the 15 W ceiling when using all ports. And if you rely on verified ratings from hundreds of users, you’ll have to wait a while for robust feedback on this new product. Under these conditions, it might be more reasonable to opt for a more established model.

Verdict: who it’s worth it for

If you want a thin power bank with an integrated cable and a display and don’t mind that it’s a new product, the AlzaPower City 10000mAh for 349 CZK is a successful compromise between size, features, and price – plus it comes with a three-year warranty. However, keep in mind that ratings are currently based on a handful of reviews and that 22.5 W applies only to one port. For a saving of 150 CZK on a model that’s on sale for the first time, it’s a reasonable entry point if you’re betting on a slim design and a brand with solid service.

Would you prefer a thin power bank with a cable at hand, or rather the largest possible capacity?
