    DO NOT BUY

    Absolute garbage, loses a full charge in under an hour. You literally have to stop charging it and immediately plug it into your device, and even then it loses its own charge faster than it charges your device. Buy literally any other charger in the world.

    It won't take a charge. Frustrating. I tried multiple cables and power sources. Nada. Clearance for a reason?

    DO NOT BUY THIS

    Saw several reviews from buyers warning that product either didn’t work upon purchase or only worked for a short period then stopped working. Well guess what. SAME THING HAPPENED TO ME! Mine was completely dead upon shipment. Gave it a full charge over several hours, plugged it into my iPhone 7... and NOTHING! Do not buy folks! Save your money.

    defective

    I was super excited that I was getting this Mophie case at a steal of a price; now I know why. I charged it and went to use it and it stopped working. I thought maybe my cable was bad so I tried it again and same thing happened. I was frustrated and disappointed to see that this trusted brand had lots of the same problems as the other reviews. I guess that's you get what you pay for.

    Purchased 2 and both DOA - what are the chances?

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I purchased 2 of these at bestbuy.com and had them shipped to my house and both arrived in a timely manner but both were DOA. They would not hold a charge after many attempts so I had to return to the store and exchange them. So far I have tested one and it works fine but it has been a PITA experience so far. Hope this helps ;)

    Charger is junk. Maybe charges my iPhone 6+ once and is dead. Buddy has a similar product of a different brand. Charges his phone 3-4 times at a cheaper cost. Don't buy this. Majority of people buy this junk for the cool colors. Don't make the mistake I did.

    heled about 1200mah of power not 4000 wouldn't charge mine or my GF phone to 60% after itself being charged fully. Bought a PNY device that has better display and holds fully 7200mAH of power and actually holds that much power don't waste your time with mophie they are just advertised more but aren't built with quality.

    Junk

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Only looks nice. Purchased this product, i fully charged it, charged a dead phone, phone was about 70% charged and this battery pack died. I wouldn't even give it a try to recharge and reuse, it shouldn't even die after charging A device and using it only once.

    Not working customer support could not help me, didn't understand my description of what it was doing. Youtube is useless, no one demos they just love listening to their own voices and ask for you to subscribe
