JP what app do you use and from where you bought it
I bought a charger 3 month ago with 18$ and I checked online the serial number it shows original it worked 2 month fine then it was giving me maximum 4w I figured out it was fake from china no original reseller in Bangladesh so I bought ugreen nexode 30w but It gave me 12w maximum usually and 17w rarely I should was bought the Anker but the Anker bangladesh said it won’t charger rapidly they said 0% hope
