On sale completely unbeatable price (under 800 CZK)
The display shows the charging power and voltage very accurately and shows it sequentially for all used ports
Thanks to its high performance, one of the few reasonably priced power banks you can really charge multiple devices at once without compromise
It can also recharge very quickly
Capacity looks realistic
Can really recharge even low-power devices
As with all Alza power banks, the battery level in % is only very indicative
workmanship is average at best

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

Nice power bank for more energy-intensive laptops. I would certainly be happy with just 65W of output and would appreciate more efficiency or capacity. Overall, I am satisfied with it mainly for the price and I give 4 stars because of overheating and low efficiency.
The design looks fine
Capable of delivering up to 140W
Very tempting price under a thousand on sale
The display shows the delivered power
Multiple outputs, pulls everything and laptops
Low power mod charges even watches
It gets quite hot even when running at lower power (around 20W) - as someone wrote here, it will have low efficiency (I will test)
Feels heavy even at the claimed 25000mAh
The body of the power bank is plastic and easily scratched
