large capacity. It doesn't charge quite as quickly and the charging speed of the devices is okay. However, so far it seems to be well built, reliable, and if you need it for travel and carry it in a bag (it's not lightweight and that's reasonable for this battery) then it's a good choice. If you find it around 40, it's okay for the money.

For the price of 36€, it was exactly what I was looking for, a home power bank. Satisfactory charging speeds for devices, although the charging of the power bank itself is moderate to slow (using a 45W power brick).
The volume and weight are almost prohibitive for use outside the house without some kind of bag.

Perfect device, high quality. The only thing that remains is to see how long it will last over time...
Of course, the price has now doubled (to 54€).
