A quality metal power bank for your pocket is useful for anyone who is often away from an outlet. AlzaPower Metal Gen2 has now dropped from 599 CZK to 389 CZK with code ALZADNY35, reaching an all-time low again – it hasn’t been this cheap since December. You can verify the current price and stock availability (which changes quickly with code promotions) directly on the product detail page.

Quick summary:
✅ Makes sense if you want a durable and popular power bank for your phone, headphones, and watch at an excellent price.
⚠️ Consider that the real usable capacity is lower than 10,000 mAh, and the power is not enough for charging a laptop.
💡 For 389 CZK, you get a metal body, three ports, and a cable included, meaning a lot of value for little money.

Why this power bank is interesting

This power bank from AlzaPower targets a classic scenario: power backup for travel and everyday use. Its main advantage is a durable metal body, which not only looks good but also better protects electronics than plastic models. It offers three ports (2× USB-C and 1× USB-A) for charging up to three devices simultaneously, and thanks to Low Power Mode, it can safely charge headphones or watches. All this in compact dimensions of 137 × 67 × 14 mm, so it fits in a pocket or a small backpack compartment.

Key parameters explained in plain language

The capacity of 10,000 mAh (37 Wh) looks great on paper, but it’s fair to know how it works in practice. This figure applies to cells at 3.6 V, so after conversion to 5 V and with losses, you will realistically get around 6,000–6,500 mAh – which translates to approximately one to two full phone charges. The output handles up to 22.5 W via USB-A and 20 W via USB-C (Power Delivery) and supports a range of charging protocols. Charging the power bank itself takes approximately 3 hours, and four LED indicators provide an overview of its status. A reversible USB-C cable is also included in the package.

Practical aspects: ports, charging, and for air travel

The power bank charges up to three devices simultaneously, but be aware: when all ports are used at once, the total output drops to 15 W, so three devices will charge more slowly. It charges via the USB-C input (max 18 W) with the included cable, but note that a wall adapter is not included, so you’ll use a charger you already own. A big plus for travelers is the 37 Wh capacity, which allows you to take it on a plane without issues (the limit is 100 Wh). On the other hand, it lacks wireless charging, and the power is insufficient for charging a laptop.

What users say

Here, the power bank really shines – it is among the most popular in its category. It has a rating of 4.7 out of 5 from 155 ratings, with 133 customers giving it five stars, and 92% of buyers recommend it. With over 2,000 units sold, it is a proven bestseller, and satisfaction is further confirmed by an exceptionally low complaint rate of 0.15%. Users most often praise its durable metal body, compact dimensions, three ports, and price-performance ratio. It proves reliable as both an everyday and travel backup.

When it doesn’t make sense

If you need to charge a laptop or want more full phone charges, opt for a more powerful model with PD 65–100 W and higher capacity – here, the ceiling is 22.5 W and realistically one to two charges. It also won’t suit people who want wireless or MagSafe charging, as this power bank is purely wired. However, as a durable and popular backup for phones, headphones, and watches for 389 CZK, it fulfills its purpose exactly.

Verdict: who it’s worth it for

The AlzaPower Metal Gen2 10000mAh is a proven and popular compact power bank – its durable metal body, three ports, included cable, and capacity that allows it through airport security make it an excellent choice for travel and everyday use. It’s important to note that the real capacity is lower than 10,000 mAh, and the power is insufficient for a laptop. For 389 CZK with code ALZADNY35 instead of the usual 599 CZK, and once again at an all-time low with a rating of 4.7 out of 5, it is one of the best value purchases in its class.

Would you bet on a durable metal body for a power bank, or is the lowest possible weight more important to you?
