BlueBuilt Power Bank 20,000 with Fast Charging 45W

Can power my recent, powerful laptop for about 3 (power-hungry) to 6 hours (average).

The form factor is a bit of a brick, which can stand flat or on its back, and has a handy display that shows how much power is going out of or into each port.

Specs say 140W: I managed to get up to 100W from 1 port, which was also pretty much the maximum my laptop draws; this was possible without the pack getting very hot. With standard use, this adds something like 5 hours of runtime to a power-hungry (20W) laptop.

I am not sure if the 140W is a maximum of 100W per port or total per port, but I also haven't found a power-hungry enough device that can draw 140W. In any case, this pack would last a maximum of 45 minutes.

All in all, a solid pack that can ensure my laptop lasts a good workday.

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.

Absolutely fantastic. Nice and compact. Fits in your pocket.
