    Unfortunately I waited to late to try this out but would not recommend. The battery pack itself dies pretty fast and the openings for the usb port seems off, as you have to practically shove it in to fit properly.

    The moment I got I charged it to 3 bars of charge and when I plugged it into my phone it doesn’t charge at all!! The indicator is on but acts as if my phone isn’t plugged in. Very disappointed, waited two hours with curbside pickup only to receive this swap meet charger. Not saluted

    20000 mAh Battery Option: Disappointed.

    Disappointed. Got 20000 mAh. Charges my IPhone extremely slow, I think it even drained my battery. It completely shuts off at 10% now. It’s also heavier than my phone, which is unnecessary. Really not worth it. Going to Amazon for a cheaper one.

    If I could give this product less stars I would. Bought it but one of the ports wouldn’t charge. Figured it was just a bad product so i exchanged it and the same issue happened again. Returned it and got my money back

    It won't charge whatever you connect to it. It will only barely keep it on. Had my phone on it and it charged maybe about 2% in 2 hours and didn't charge my little JBL pill speaker. Terrible product! Look for another brand and save your money.
