Metal power bank for three hundred crowns. This super popular model has 10,000 mAh and four ports

Looking for a quality power bank that won’t break the bank? The AlzaPower Metal 10000mAh Fast Charge + PD3.0 is now available at a significantly reduced price. From the usual 549 CZK, it has been discounted to just 329 CZK, with the offer valid when using discount code ALZADNY40. What parameters does this power bank offer and for whom is it actually suitable?

Compact power bank with three ports

The AlzaPower Metal 10000mAh boasts an elegant metal body with dimensions of 67 × 137 × 14 mm and a weight of 225 g. Although the manufacturer states an all-metal design, some reviews suggest it’s more of a pseudo-metal look, but this doesn’t detract much from the overall impression. Due to the metal body, you can expect the power bank to scratch over time, which is a common phenomenon with similar products.

Regarding connectivity, the power bank offers two USB-A outputs (5V/3A, 9V/2A, 12V/1.5A) and one combined USB-C input/output (5V/3A, 9V/2A, 12V/1.5A). For charging the power bank itself, either the USB-C port or the Micro USB input can be used. Thanks to this configuration, you can charge up to three devices simultaneously, which is especially practical when traveling with multiple gadgets.

What about actual power and capacity?

The manufacturer states a capacity of 10,000 mAh (37 Wh), which is a standard value for a power bank with smaller dimensions. In real-world operation, however, we must account for energy losses that occur during voltage conversion between the power bank and the device being charged. These losses typically range around 20-30% of the capacity. Considering the battery capacity of current smartphones, the power bank will realistically offer approximately one and a portion of another charge for a typical phone. For charging headphones, smartwatches, and similar devices with smaller batteries, the capacity will suffice for many more cycles.

The power bank supports several fast charging protocols: Power Delivery 3.0, Qualcomm Quick Charge 3.0, and others including Samsung AFC or Apple 2.4A. The maximum power output is 18 W, which is certainly not a record, but given how much the power bank costs now, we cannot expect miracles. For today’s phones, it might be slower, especially if you have a Chinese model and are used to at least 45W charging, but you probably won’t notice a difference with accessories.

Who is this power bank suitable for?

The AlzaPower Metal 10000mAh is an ideal companion for everyday users who need a reliable power source for one to two days away from a power outlet. Thanks to its compact dimensions, you can comfortably store it in a backpack or a larger pocket without it unnecessarily weighing you down.

The power bank is particularly suitable for:

• Traveling on day trips when you need to recharge your phone and possibly other small electronics.
• Business meetings outside the office, where you’ll appreciate the option of simultaneously charging your phone and tablet.
• Users who want a solid power bank at an affordable price

However, if you are a more demanding user who spends several days in the field or needs to charge more powerful devices like laptops, you will need a power bank with a larger capacity and higher maximum power output.

What do customers say in reviews?

The power bank has a rating of 4.7 out of 5 stars on Alza based on over 1400 reviews, which is an impressive number. Let’s look at what customers specifically appreciate and what they dislike.

Positives according to customers

• Quality metal craftsmanship that feels premium
• Compact dimensions suitable for portability
• Fast charging of connected devices
• Excellent price/performance ratio, especially at the promotional price

Negatives according to customers

• Metal surface scratches easily
• Some users report lower actual capacity than stated
• Slower charging of the power bank itself (3.5–6 hours)
• The body can be slippery in hand
• LED charge status indication could be more precise (only 4 diodes)

One reviewer offered an interesting insight: “Given the exceptionally high efficiency at 5V 1A (5W) draw, the real capacity is probably higher than the stated 37 Wh.” This suggests that the power bank might be more efficient at lower power draw.

Verdict: A solid choice at an excellent price

The AlzaPower Metal 10000mAh Fast Charge + PD3.0 represents an excellent price-to-performance ratio, especially now that it’s available for just 329 CZK. The power bank offers sufficient capacity for everyday users, support for modern fast charging standards, and the ability to charge multiple devices simultaneously.

Although it doesn’t offer the latest technologies like wireless charging and the highest power outputs for charging laptops, it reliably performs its basic function, and for its price, it’s one of the best products on the market. The ALZADNY40 code promotion is valid for a limited time only, so if you are considering purchasing this power bank, don’t hesitate too long.
