18 W via USB-A, 30 W via USB-C.
One USB-C built-in cable, one USB-C connector, one USB-A connector.

met expectations
a USB-C cable is included, which also serves as a handling strap - so far it seems that it could be durable and durable enough; in case of its failure, however, a separate cable can also be used
handles charging multiple devices at once without problems
relatively high capacity (but with which it is possible to board most airlines without problems)
out of the box, the first thing that catches the eye is the weight, which is quite logical considering the battery capacity

Despite the drawbacks (mainly charging speed), I would buy it again because of its compactness, smart built-in cable and high capacity.
Very light for its capacity (the lightest available at the time)
Intelligently implemented built-in cable (used for charging both the power bank and the connecting device). When I'm not charging them, it serves as a strap
Nice display, where you can of course see the charge level but also the icon if it is Fast charging
When charging the Macbook, it overheats very quickly and the charge drops to only some 18 W
When you connect multiple devices at the same time, they all charge very slowly
Pass through charging is then so slow that it won't even charge you overnight via the fast charger itself (powerbank) + connected phone
The dark plastic on the body of the power bank scratches quite easily

The Macbook (slowly, of course) charges for just a moment and then shuts down after a few minutes
