Extremely popular 10,000mAh power bank for 300 CZK. AlzaPower Parade is now on sale, has a display and four ports

Alza has significantly discounted its best-selling power bank AlzaPower Parade 10000mAh Power Delivery. From the original 599 CZK, the price dropped to just 300 crowns when using the discount code ALZADNY50. For this amount, you get a power bank with up to 22.5W output and an LCD display showing the precise battery status.

What the power bank actually offers

AlzaPower Parade features a Li-Polymer battery with a capacity of 10,000 mAh (37 Wh). In practice, this means it can charge an average smartphone with a 4000-5000 mAh battery approximately 1.5 to a maximum of two times. Due to voltage conversion and efficiency losses, you typically only utilize 60–70% of the nominal capacity.

The power bank offers three outputs for simultaneous charging – two USB-A ports and one USB-C, which also functions as an input. The maximum output power is 22.5 W via USB-A or 20 W via USB-C with Power Delivery 3.0 support. It also supports Quick Charge 3.0, Samsung Adaptive Fast Charge, and six other charging protocols.

Compact dimensions and practical display

With dimensions of 68 × 139 × 16 mm and a weight of 210 grams, it is among the more compact models. The LCD display shows the remaining capacity in percentages, which you will appreciate when planning your charging. The power bank itself charges in approximately 4 hours via USB-C (18W) or the Micro USB input, which is located on the side of the casing.

The package includes a reversible USB-C cable and a manual. The power bank features six-fold protection against overvoltage, overload, short circuit, overheating, overcharging, and under-discharge. The body is made of flame-retardant material according to UL94 standard.

What users say after almost 2,000 reviews

The power bank received a rating of 4.6 out of 5 stars from 1998 customers. Alza sold over 20,000 units with a mere 2.07% return rate, indicating solid quality. A full 92% of buyers would recommend the product to others.

Users most often praise the AlzaPower Parade 10,000 mAh power bank for its fast charging, favorable price, compact dimensions, and low weight. The practical display with percentage indicator, the versatility of the ports, and its ability to charge a phone multiple times on a single charge are also positively rated. Many customers also highlight the pleasant design and good price/performance ratio.

Conversely, among the more frequent criticisms are lower real capacity compared to declared, sometimes unstable or inaccurate battery status display, and faster cell wear. Some users criticize the limited number of USB-C ports, occasional display defects, or whistling during charging. Another negative is shorter lifespan, where after one to two years of more intensive use, the capacity noticeably decreases. Overall, however, positive experiences significantly outweigh the negatives.
