QOOVI 22.5W Power Bank 20000mAh Portable PD20W Fast Charging Poverbank Mobile Phone External Battery Portable Charger For Samsung iPhone Xiaomi

Good morning, I don't know if it's because it took a long time to arrive, I don't know If it is because the product is defective but the power bank that I ordered was supposed to be fast charging and of course if you plug it into the mobile phone with 100% charge in the power bank and with thirty-something battery percentage on the phone, what doesn't seem normal to me is that in practically an hour it only goes up Only 3 or 4% of the phone's battery is charged because if that's the case with fast charging, how can it be with slow charging? Deeply disappointed with the purchase. And this is without taking into account that when you charge it with a power bank it also takes a long time to reach 100%.

very satisfied!I charged the phone once!From 80 percent it went down to 66 percent!So it used 12 percent on one charge!I think I have about 4 full charges!

It's good, keeping charge perfectly. The only reason for 4 star it is not 20 000 mah. It's about 16-17000

It's a bit hard for a product that claims to be one you can always have on hand.
