Laptop power bank for a great price! Hama has 24,000 mAh and a useful display

You’re sitting on a train, your laptop is showing the last few percent, and there’s no outlet anywhere. This is exactly the situation where a larger power bank makes sense — if it can deliver the power your computer needs. The Hama High Power 150 W offers two powerful USB-C ports, a capacity of 24,000 mAh, and a display where you can see what’s really happening during charging. On Alza, it now costs CZK 1,129 without a code. That’s a price that makes it worth considering even alongside more well-known charging brands.

Quick summary:
✅ Makes sense for: Your backpack for your laptop and phone, when you want to charge quickly even out of reach of an outlet.
⚠ Consider: It weighs 639 grams and is not a small pocket backup. Performance also depends on the connected device.
💡 The price is CZK 1,129, availability on Alza is “in stock with supplier”. Check delivery time before ordering.

Two USB-C ports that are not just for show

The total maximum output is 150 W. From a single USB-C port, you can get up to 140 W, but only with a compatible device supporting the corresponding USB Power Delivery 3.1 mode. When both USB-C ports are connected, the power is split into 65 + 65 W. This is more practical than one fast connector and another that barely suffices for a phone. A typical work laptop with USB-C charging support can thus receive a decent power supply simultaneously with another device.

The color display shows the remaining capacity and the output of individual ports. This makes it easy to see if your laptop is actually drawing tens of watts. The package includes a half-meter USB-C cable rated for up to 240 W — this value refers to the cable, not the power bank’s output.

Quickly charged in tests, but no miracles at the end of the battery life

Techtest tested a unit provided by the manufacturer and measured a full charge in 61 minutes at an input of around 95 W. This is convenient if you’re topping up the power bank quickly before a trip; however, with a slower adapter, expect a longer time. The review also showed a limitation: with continuous draw of 140 W, the output dropped to 65 W once approximately 30% capacity remained. Thus, the maximum output does not last until complete discharge.

Do you already carry a power bank for your laptop, or do you only use it for your phone?
