As someone already wrote here - charging laptops (and actually iPhones) rather doesn't work. With the M4 macbook, I had both the macbook and the powerbank discharging, the macbook reported that it was charging, but realistically its battery charge was dropping. And at the same time, the power bank was being developed! With the Asus laptop with usbc, which so far willingly let me charge somewhere, I have failed to succeed here. I've tried USB A, USB C, various cables, without success. It wasn't charging at all. I have an older powerbank and this was supposed to be an upgrade, unfortunately I ended up having to return this new one. Oh, and I was most surprised that the powerbank "jammed" when charging from the charger, it had to be unplugged and plugged in to continue charging itself. Swisstem never again, I'll take the same brand I've already tried.: )
Relatively small dimensions
Alza quickly refunded the money for the returned item
Charging PD not working
Powerbank charging sometimes gets stuck

Charging with this powerbank is a lottery. usually doesn't work at all. My main concern was charging via PD and USB-C port. Unfortunately, a big mistake. Neither macbook nor classic laptop can be charged immediately after connection. Twice the PD indication lit up on the display and the laptop started charging, but that was more of a coincidence. Through the classic ports, the mobile can usually be charged, but the power bank was purchased for charging a laptop, which has severely missed the effect. We are disappointed and very dissatisfied.
cannot be overlooked
it works for practically nothing.
The USB-C port is so recessed that the laptop can't be reliably charged with the included (and for my taste very thin) cable, nor with another purchased

after purchase, I have charged my iPhone and iPad several times on the road with this powerbank. However, I was very surprised that when I charged the iPad overnight, the power bank was empty by morning.
So I bought a USB tester and found that the power bank has 30% less capacity than advertised - only 98 Wh from full charge to full discharge compared to the announced 148 Wh.
For this reason I recommend not to buy this powerbank at all!
Modern power bank supporting fast power supply and modern QC and PD protocols
Nice look
real capacity is only 98 Wh compared to the announced 148 Wh - measured with a tester
