No problem.
I took a longer look through the various product specification documents. Did not note any Joules rating.
You posted that you live in Macedonia - the surge protector is for "Germany". Does Macedonia use the same outlet/plug standards?
From the product link (my italics)
- PURE POWER
- Protects valuable equipment from harmful power surges
- Suitable for high power consumption devices
Pure power: Not sure what that really means. However power strips do nothing to add power or clean up power.
Protects from "harmful power surges" - no ratings or explanation. Maybe just the built in 16 A breaker.
Suitable for high power consumption devices. Such as.....? How is "high power defined" ? Again no specifics and I would be very surprised if the power strip would support, for example, a washing machine
. (Which should never be run via a power strip in any case.)
Mostly vague and subjective and lacking technical details.
Summary: the power strip appears to be a low end product that is shy of meaningful documentation and supporting facts that I would look for.
Although color, cord length, etc. have some relevancy those features are not important. How well the power strip is designed, what materials are used, how well assembled, and tested are all far more important.
Look for brand name products that are known, well rated, and available in your area. Avoid discount bin/box items often sold in bulk for low prices.
Go online and look for product reviews by known reviewers.
For example (not an endorsement or product recommendation):

Try to find review links applicable to power strip products available within your country.
May be more than you wish to spend - still less costly than replacing damaged or destroyed electronics.
Just my thoughts on the matter.
