I just bought this on Amazon, and tried to charge it and it would only sometimes shows 21 on the screen and then goes blank, and then sometimes shows 21 again. I tried to charge over night and its still the same. I thought maybe it was because I didn't have the 90W GAN charger, so I ordered that. And its still the same thing after 4 hours.
I tried plugging my phone into the battery to see if it would charge my phone, and it doesn't even charge the phone.
Is there something I else I need to do or I need to return the X6G and the charger.
