good price
quite compact
From time to time, it's noisy when dispensing – a rushing or even a whistling sound.

Excellent for fast charging.
The USB to USB-C cable is missing. I received a dual USB-C in the package.

Small and compact with a large capacity. And on top of that, it's also relatively light compared to similar solutions. Ideal for a backpack for a trip into town or into the countryside.

The power bank does what it's supposed to. It would be sad if it didn't. But what I'm literally fascinated by is the box. I don't know where to start. The paper is sturdy, recycled. The ink for the print is soy-based. The packaging exactly matches the size of the product, so no air is being stored or transported. That perforated 'open here' sticker snapped so nicely. Simply put, even just unboxing the product was a positive experience for me. Especially when you compare it to, say, an impenetrable blister pack. A big thanks to whoever deals with such a 'silly' thing as packaging.
He's doing what he's supposed to do.
