We’ll see how it goes in the long run, but I’m happy with it so far. It’s a reasonable size and weight; it can charge both a laptop and a mobile phone, and charges itself fairly quickly. The data on the display is updated approximately twice a second, with ports alternating every 5 seconds. It would be useful to have information on average consumption and remaining battery life. It charges at full power right up to 100 per cent, which surprised me – I’d be a bit concerned about the battery life, but it’s nice from a quick-charge perspective.
0.5 m USB C-C cable included
It can charge itself and supply power to the output at the same time
It displays the voltage and instantaneous power for each port individually during both charging and discharging (the data for each port is shown in turn)
It charges to around 70% in the first hour, and reaches a full charge in around 1.5 hours – which is actually less than the stated 2 hours
Discharging via port C2 (up to 100 W) stops at 5 per cent; via C1 (up to 65 W), it allows the level to drop below
When fully charged, it shows 100% and the "%" (charging indicator) stops flashing
Actually, just a few minor things, nothing major:
It seems that port C1 is slightly less efficient than port C2
It gets noticeably warm, but not uncomfortably so; it’s within acceptable limits (though I haven’t tested it at full load, only at about 50 per cent of its capacity)
From the description, it gives the slight impression that it charges at 100 W, but that’s not the case – the charging power is 64 W via C2; When using the C1 port, the power output is a few watts lower (61 W) – figures from the power bank’s display
If there is power consumption on the other ports after the device is fully charged, the power consumption is also displayed on the charging port – which makes sense – but because the % no longer flashes, it looks as though power is flowing back into the charger, although that is certainly not the case: -)

utterly satisfied after the first use
Collected today following an order
From 27%, the first charge to 100% was carried out using a 65W charger
Connected an HP EliteBook 855 G7 laptop to a 65W socket
Charged to 93% after approx. 45 minutes
The power bank has 49% battery left
I hope it will charge a tablet as well, if necessary

Sometimes there isn’t enough space, in which case you’ll need to take two or buy a bigger one (though that won’t be allowed on the plane).
Maximum capacity per aircraft
It charges itself quickly
It charges other devices quickly
It can charge other devices whilst being charged itself

the product should be called perpetuum mobile, sometimes when I charge my phone, besides the percentage on the phone, the percentage on the powerbace also increases: D otherwise it works decently, it can charge and discharge at the same time, it handles the declared power and of course it gets a bit hot, but I don't think it's anything terrible with the power it handles.

Runs perfectly, only the plastics creak between each other, but that's a minor detail
