Why this power bank is interesting

This power bank from FIXED targets those who need a lot of power for travel. With a capacity of 30,000 mAh, it can charge a phone with a 5,000 mAh battery approximately five times. This means you’ll be fine on a multi-day trip or vacation without access to an outlet.

Charging: three ports and Power Delivery

The power bank features two USB-A ports and one USB-C with Power Delivery 3.0 support. The USB-C port can output up to 20 W, while the USB-A ports can output up to 22.5 W. When charging all three devices simultaneously, the power is distributed to a maximum of 15 W (5 V / 3 A).

A practical feature is Pass Through Charging – you can charge two devices via USB-A while the power bank itself recharges via USB-C. One user in the reviews also discovered an undocumented Low Power mode for charging watches or headphones – it’s activated by holding the button until an animation starts to appear in the last digit.

Practical aspects: display, dimensions, in the package

The LCD display on the side shows the current charge status in percentages – just press the button. Charging starts automatically immediately after connecting a device, without needing to press anything. A USB-C/USB-C cable is included in the package.

The weight of 597 g corresponds to its capacity – it’s not a pocket power bank, but it fits into a backpack or bag without issues. The built-in Li-Pol battery (3× Li-polymer 1260110) is protected against short circuit, overload, and overheating.

What users say

On Alza, the power bank has a rating of 4.7 out of 5 (45 ratings) and 89% of customers recommend it. Over 2,000 units have been sold with a low return rate of 0.6%. Users most often praise its capacity, price/performance ratio, and Power Delivery. One reviewer writes: “At 550, an unbeatable price/performance ratio.”

Critical voices appear regarding manufacturing details. Several users point out the quality of the connectors – they move along with the display when inserting a cable because they are not firmly attached to the casing. The glossy surface quickly collects fingerprints and is prone to scratches. The button for activating the display feels cheaper according to some reviews. However, these are expected compromises at this price point.

Verdict: who it’s worth it for

If you are looking for high capacity at a reasonable price and don’t mind the higher weight, this discount is definitely interesting. For 699 CZK, you get 30,000 mAh, three outputs, 20 W Power Delivery, and an LCD display. This is a combination that is hard to beat in this price category. Conversely, if you are looking for a compact pocket power bank or care about premium craftsmanship, it’s worth considering smaller capacities or more expensive models.
