The new AlzaPower Fusion power bank impresses with a nice display and two integrated cables

A power bank where you don’t have to worry about cables and can also see exactly what’s happening during charging is a practical item for travel and work. The new AlzaPower Fusion 25,000 mAh with two integrated cables and a display is sold for 1,999 CZK. It offers a combined output of up to 170 W and 100 W per port.

Quick summary:
✅ Makes sense if you want a large power bank for both a laptop and a phone, don’t want to carry cables, and appreciate the overview on the display.
⚠️ Consider that the 170 W figure is a sum across multiple outputs — it provides a maximum of 100 W to a single device, and the integrated cables are relatively short.
💡 For 1,999 CZK you get a well-equipped unit with a three-year warranty, but expect a higher weight due to its capacity.

Why this power bank is interesting

The main advantage of the AlzaPower Fusion power bank is a combination of three things: high capacity, two integrated cables, and a clear display. Thanks to two built-in 25cm USB-C cables, you don’t have to carry your own cabling, and since both support Power Delivery with up to 100 W output, you can charge a laptop with them, not just a phone.

The power bank can charge up to four devices simultaneously, and power distribution is handled by the Smart IC chip, which automatically recognizes connected devices. This is a new product from the AlzaPower brand with a three-year warranty, so it’s not an unknown item, but a product from Alza’s established private label series.

What the color display shows

The display is what makes Fusion a smarter power bank than you’re used to. It shows the remaining capacity, current input and output power in watts, active ports, and the power of individual outputs. When recharging the power bank, there’s also an estimated time to full charge and a fast charging indicator, so you immediately know how long to wait.

You also have an overview when the power bank is simultaneously recharging itself and charging a connected device (Pass Through Charging). For more technically inclined users, a bonus is that the display also shows temperature, battery health, and the number of charging cycles — data by which you can assess the long-term condition of the battery. All important information is thus visible at any time without connecting to an application.

Key parameters explained in plain language

The capacity is stated as 25,000 mAh, or 90 Wh. Watt-hours are a more honest metric than mAh, and here’s the double good news: 90 Wh means a decent reserve for several phone recharges and laptop top-ups, and at the same time, this number remains below the 100 Wh limit, so you can take the power bank on a plane. Just keep in mind that the realistically usable capacity will be slightly lower due to normal voltage conversion losses.

Connectivity consists of two integrated USB-C cables, a separate USB-C port, and one USB-A. It’s crucial to understand the outputs: each USB-C can handle up to 100 W (ideal for laptops), while USB-A only 18 W. The declared up to 170 W is the sum when using multiple outputs simultaneously, not the power to a single device. The power bank itself can be recharged in approximately 1.6 hours with a 100W adapter, which is pleasantly fast for this capacity.

Practical aspects: cables, modes, safety

The biggest practical advantage is the integrated cables, which you always have at hand and don’t have to search for in your backpack. For small electronics, there’s a Low Power Mode (activated by double-pressing the button), which allows you to charge headphones or smartwatches without the power bank disconnecting them due to low power draw. Safe operation is ensured by sixfold protection against overvoltage, overload, short circuit, overheating, overcharging, and excessive discharge.

One thing to mention: the integrated cables are short (25 cm), which is great for travel and compactness, but they might be too short when using devices further away from the power bank. The power bank also supports Pass Through Charging, meaning it can simultaneously recharge itself and a connected device, so it can also serve as a continuous power source on a desk.

What to watch out for

The most important thing is to correctly understand the power outputs. The 170 W figure is combined, and the power bank delivers a maximum of 100 W to a single device via USB-C; the USB-A port with 18 W is more supplementary. Also, keep in mind that with a capacity of 25,000 mAh, this is a heavier unit that you won’t carry in your pocket but is suitable for a backpack.

The mentioned short 25cm cables are a compromise between compactness and convenience of use. And just like with other universal power banks, for phones with their own super-fast charging (typically Xiaomi), the device may not receive its highest speed, but standard fast charging will work without issue.

When it doesn’t make sense

If you only charge a phone and don’t need power for a laptop, the Fusion is unnecessarily large and heavy, and a lighter power bank with smaller capacity will fit better in your pocket. Similarly, if you prefer longer cables or carry your own, the advantage of the integrated 25cm cables won’t be as crucial for you. And if you don’t care about the display or power overview, you’ll save money with a simpler model without a screen.

Verdict: who it’s suitable for

The AlzaPower Fusion is a great choice for laptop owners and more demanding users who want high capacity, 100 W power, and most importantly, don’t want to deal with cables. For 1,999 CZK, you get two integrated cables, a clear display, the ability to charge four devices at once, and a three-year warranty, and thanks to 90 Wh, you can take it on a plane. Expect higher weight, short cables, and that 170 W is a combined output. Those who can handle this and genuinely utilize the power will get a well-equipped power bank for 1,999 CZK. Those who only charge a phone should opt for a lighter model.

Would you appreciate integrated cables on a power bank, or would you prefer your own longer ones?
