Transducer efficiency is 84%
Really small against the competition
One of the lightest 20.000mAh powerbanks - 295g
Display (even though the last % goes down by leaps and bounds)
Price
Integrated cable may bother some people, looks awkward
Realistically, it delivered 12,470mAh at 5V (remember that 20,000mAh is at 3.7V)

the lightest 20 Ah budget powerbank
35 watt is awesome and it actually gives those 35 as stated (measured with a smart cable)
only 295g (not 297 as stated)
theoretically the lightest 20Ah you can get (even the carbon nitecore weighs 293 g (but it doesn't have an integrated cable, so it would be heavier with it)
really small
35w also charges
display with percentages
low energy mode
eco packaging
product description
construction and design integrated cable can also be charged
price (580 CZK)
charged to about 70% I don't know exactly
the cable could be at least 5 cm longer, right
the display could show more information
the supplied cable should be C to C in 2026 and not A to C as they give

For little money, even AlzaPower has it all. What I missed with one powerbank and other brands was with another and vice versa. And if she already had it all, she also had extra unnecessary "stuff" for more money. For the average user, a blast.
Integrated USB-C cable
Fast charging up to 35W
Additional USB-C to C cable included
Price (purchase for 600 CZK)
Low Power Mode for safer charging of watches/earphones (but don't look for adapters in the package)
I don't think it's even very big
The manual does not tell you about the Low Power Mode function or how to start it

capacity met expectations
one of the lightest besides Nitecore specialties
I am concerned about the lifetime of the built-in cable when carrying it on treks
