So, I have bought a total of 3. First one by itself, and after it broke (who would have thought it would be a defective product), I bought 2 extra together. All 3 broke within 3 months. If the wireless charging stops working, charging with a cable doesn't work either. Literally wasted money. Stay away.

I bought it for iPhone 13 Pro Max. Maybe because of the phone's battery it heats up easily. Maybe for a smaller iPhone it would be just fine. Nevertheless, very convenient and of good quality construction.

It swelled after 11 months of use.
Charged once every 20 days a 14 Pro Max with a MagSafe Pitaka case.

When it was charging, the phone was burning.

Suddenly, and after 15 days in the drawer, it swelled on its own.

Skroutz Plus (fortunately) gave me the option to return the amount.

Go for something more branded/expensive.

There are many like this, they are mass-produced.

Fast charging. It takes a bit of effort to align it properly with the phone, but if you get it right, it charges satisfactorily quickly and without getting too hot.

The extender worked normally and was indeed very convenient, but after 20 days it stopped charging the power bank, so it became useless. This may be due to the specific piece that I received, of course. The issue is that from the store I was informed that the supplier sets a 14-day return policy, so I was left with the now useless extender.

Very useful accessory for anyone who is out for many hours…
It charges slowly, gets warm but does its job…
Owner of iPhone 13 mini
update (December 25) after a few months of use, it stopped charging and is useless...
I don't know if it is covered by warranty...

Very convenient and charges the mobile relatively quickly.
The only disadvantage is that the battery takes a long time to charge

Very nice brand but indeed the mobile phone and powerbank get hot, resulting in having to go for a motherboard if you do about 10 charges..!
iPhone 15pro max
Stay away! That's why it's cheap..

Very good construction. It charges the iPhone 14 Pro Max satisfactorily twice (from 20%), slowly but steadily. Good magnetism relative to its weight. In the attempt to charge Airpods Pro 2 (MagSafe), you have to place them vertically on the charger for it to start charging, otherwise it makes attempts and stops until it closes. An attempt was made to charge the Apple Watch 7th Gen with its cable, but it did not have consistent results. It showed that it was charging and then stopped after a while.

It does its job, but it is much bigger than the photo, therefore heavier than what I wanted

My personal opinion is very good.
It charges the phone quickly (15W wireless charging, 20W wired charging).
It does not raise the temperature.
As for the build quality, it is very good and the magnet is very stable on the back of the iPhone. The power bank itself charges quickly as well.
The only negative thing I find is that even though it is very small, it is heavy.
