    Works Great!
  

*by S***R on Reviewed in the United States on September 22, 2019*

This works amazingly. I was excited to use the charger at a concert yesterday. It was just what I needed. It’s not a super fast charge, but that didn’t matter. What matters is that my phone stayed charged throughout the day.

    Better than expected
  

*by T***S on Reviewed in the United States on September 22, 2019*

My job revolves around my phone every single day, I use my phone for probably 3 hours a day of gps to get to appointments and then the complete each appoint and anything else I need my phone for during the day, this phone case charges as my phone charges at night and they both leave 100% charged in the morning, after getting home from 12 hours of work my phone will be 100% charged and the case will still be half way charged at the end of the day, for under $30 this is a no brainer

    Buyer beware and buy something else!
  

*by J***N on Reviewed in the United States on December 29, 2019*

This is my second review of this product and honestly I feel worse about this product than the first time I reviewed it.  The first time I reviewed it I had a problem with the connector.  It loosens up and won’t hold the lightning connector in it.  After that review the company did step and sent me a new case.  I felt somewhat better.However here I am a little over a month later with the same exact problem.  At this point I’ve decided to completely give up on this PIECE OF JUNK case.  The quality of the connector is shabby at best, and is truly cheaply made and unreliable.  I would absolutely suggest bypassing your purchase of this item.I just purchased a new case and will just have to move on from here and consider this a complete loss.Save your money and go somewhere else.
