Verified purchase - review from a price comparison website
The power bank has a large enough charging capacity, it lasts a very long time, we had an older one with a weaker capacity and that makes a difference. And the price of this product was a big plus. Definitely worth the purchase.
It's a heavy brick, probably gets worn out on the road, takes a long time to charge, but these are negligible minuses.

Verified purchase - review from a price comparison website
I am satisfied with the powerbank. I bought the 50 000 mAh variant for 844 CZK on sale, so I counted on the fact that due to the very low price and high capacity I may encounter some compromises. People complain that the power bank charges slowly. This is an extremely stupid criticism in my opinion, because the powerbank indicates an input power of max. 18w and this power according to my measurements can really manage to charge. That you can't charge a 50,000 mAh 18w fast is simply physics, the powerbank nowhere promises to charge fast. He promises 18w input and he takes it. At this rate, simply charging an empty powerbank of this size takes over 10 hours and there is nothing you can do about it. My only complaint is with the output power. The powerbank promises up to 22.5w output power via USB-A, but on my phone (Poco F8 Ultra) I managed to achieve a maximum of 15w when measuring. You should therefore expect your phone to take a little longer to charge. Maybe with other phone models it can reach full 22,5w power, I can't test it, just pointing out what I measured. Overall, despite my complaint, I am satisfied with my purchase. Getting a 50,000 mAh power supply for 844 Kč is just a bargain. For a weekend under a tent, for a festival for a few days or in your backpack for a few days hike, it's perfect. Of course, the weight and dimensions are higher, but given the capacity, this cannot be taken as a criticism, but as a feature. No one expects a 50,000 mAh power bank to be light and pocketable for everyday use.
Display shows charge percentage
Large capacity
Very favourable price
It has a practical loop
In practice I managed to measure the output power max. 15w
Input power could be higher than 18w due to the charging speed of the powerbank
some people here mention the scratched display. Like, I seriously wonder if they're really that stupid or what's going on. Whether they were born that way or it just happened over time. THERE IS A FOIL GLUED ON THE DISPLAY IS NOT SCRATCHED!
