Alza discounted a metal power bank that can charge three devices simultaneously. Users praise it

Are you looking for an affordable power bank with 10,000mAh capacity and care about its construction? The metal model AlzaPower Metal Gen2 10000mAh can now be bought for 449 Kč with discount code ALZADNY25, which is the lowest price since December. It has excellent ratings in user reviews.

Quick summary:
✅ Makes sense, if you are looking for a compact power bank for travel with fast charging and don’t want a plastic design.
⚠️ Consider, if you need to power a laptop or want wireless charging – this model is not built for that.
💡 For 449 Kč you get a metal body, 3 output ports, PD 3.0/QC 3.0 support and a 3-year warranty – that’s above standard in this category.

Why this power bank is interesting

AlzaPower Metal Gen2 targets users who want something between the cheapest plastic models and expensive premium power banks. The metal body feels solid, dissipates heat better, and withstands normal handling in a backpack or pocket. A capacity of 10,000 mAh practically means about 2–3 full charges for a typical smartphone – usually sufficient for a weekend trip or business travel.

Key parameters in practice

The power bank features two USB-C ports and one USB-A, allowing you to charge up to three devices simultaneously. The maximum power output reaches 22.5 W on USB-A and 20 W via USB-C (Power Delivery). Support for protocols like PD 3.0, QC 3.0, AFC, FCP, and others ensures compatibility with most phones from Samsung, Apple, Xiaomi, and other brands.

The power bank itself charges in approximately 3 hours (at 9V/2A). The package includes a 30 cm reversible USB-C cable, so you don’t have to immediately look for additional accessories. Dimensions of 137 × 67 × 14 mm correspond roughly to the size of a larger phone – it fits easily into a jacket pocket.

Practical aspects: modes, safety, warranty

A useful feature is Low Power Mode – you activate it by holding the button for 2 seconds, and it allows you to safely charge low-power devices such as wireless headphones or smartwatches. Without this mode, the power bank might automatically turn off, thinking nothing is connected.

Safety is ensured by 6-fold protection against overvoltage, overload, short circuit, overheating, overcharging, and under-discharging. The charging status is indicated by 4 LED indicators. And an important detail: Alza provides a 36-month warranty for this model, which is above standard for power banks (however, a shorter period may apply to the battery as a consumable item).

What users say

On Alza, the power bank has a rating of 4.8 out of 5 (115 ratings) and 97% of customers recommend it. The return rate is very low – only 0.1%. Users most often praise the charging speed, solid metal construction, and the fact that a USB-C cable is included in the package. One reviewer mentioned that for the promotional price of around 400 Kč, it’s a “top pick”.

Critical feedback mostly concerns details: Low Power Mode does not activate automatically (you have to turn it on manually), which some users find inconvenient. One user of the 20,000 mAh variant noted that when simultaneously charging the power bank and a connected device, fast charging drops to a slow 5V. And in winter, it might be necessary to “warm up” the power bank under a jacket before it starts working correctly – but this is a general characteristic of lithium batteries.

When it doesn’t make sense

If you need to charge a laptop, this is not the right choice – the maximum output voltage of 12V is not sufficient for most laptops. Similarly, you won’t find wireless charging or MagSafe here.

Verdict: who it’s worth it for

For 449 Kč, you get a power bank with a metal body, three outputs, fast charging support, and a 3-year warranty. This is a hard-to-beat combination in this price category. The model is suitable for everyday carry, shorter trips, or as a backup in a backpack. If you’re not looking for extreme capacity or laptop charging, it’s a very reasonable choice – especially now that the price is at its lowest since December.
