Great product

Fits in your pocket, charges quickly
It is ideal that you can see how much capacity is left on the side.

I bought this power bank to film or take photos outside the car with my dashcam.

Contrary to what Coolblue claims about it not fitting in your pocket, the device fits perfectly in your pocket.

Unless you are a resident of Madurodam; in that case, no, it won't fit in your pocket.

I myself am not from Madurodam; I am a real person and have no problem with it.

Moreover, the product charges quickly.

It comes with a 3-year warranty.

High quality and robust

Compact size
Solidly built
Display with battery percentage

A solid power bank and nicely compact for its capacity. Connecting a laptop works well, and you can power the laptop from the battery while simultaneously charging the battery.

Info: The 45-Watt output/input USB-C is the one near the display. The 30-Watt output/input USB-C is the other one and is called C1.

Wish: A color indicator (red) around the 45-Watt USB-C port near the display would be nice to show that this is the high-power port.

Compact power bank suitable for charging a laptop

More compact than the older BlueBluit model
Charge phone and laptop quickly
One cable is included.
The display looks slightly cheaper than on the product page.

The Coolblue power bank. Nice, compact, and much smaller than the previous 20W model. Charging the power bank is lightning fast. Handy for charging your phone and laptop on the go. Also very useful when there isn't a power outlet nearby for your laptop. This power bank gives even your laptop enough power in that situation!

There is, however, one downside. It lists a 50cm and a 20cm USB cable. But there is only one, the 50cm one. This could be a problem if you exchange or return it, as they assume you are returning two cables!
