8*18650 Battery DIY Power Bank Case Charge Storage Box Dual USB Type C Battery Holder Box PD QC3.0 Quick Charge For SmartPhones

there is fast and super fast charging, for the power bank to work, you need to put it on charge for a second, even from another power bank, it charges iPhone 15, it charges itself from 80w fast charging. . . it says fast, I need a quality USB tester, my cheap Chinese one doesn't measure fast, only 5 volts. . . , but no, it does measure, but when you turn on the camera, it disables fast charging 9V+, 1A+, so you have to take my word for it, 9.25*1.03≈9.3W is not 80.60, and not even 20W, but the phone sees it as super fast charging. . . Overall, I am satisfied with the product, it cost 315 UAH, and it arrived in Bucha quite quickly. . .
