    I would never recommend this phone to anyone. My family has told me they are trying to call and it goes straight to voicemail. From the same car they have showed me. It's fully charged and volume on. Turn it off and back on works good for about 12 hours then starts again

    We returned this because it would not charge to 100% and would not hold a charge. What good is a charger backup battery that won’t charge up and won’t hold a charge.

    This item charged to 100 % but would not charge a phone. I tried 4 different cords with no luck. I am willing to return it and try a different one because I have always trusted Energizer products. I may have gotten one that was made during Covid.
