    I purchased this product for an event. The day if the event, it never worked. When I tried to return it, I was told it was passed the 15 return date. I was not aware it was only 15 days. I thought it was 30 days. I asked if they could switch it for another or a store credit, I was told no. $40 wasted!!!

    No, I would not recommend this to a friend

    It was already charged 77% when I got it. So I tried to charge my phone but then battery depleted after within 30 min. It took me 12 hours to charge the power bank for 36%. I was really disappointed this Energizer power bank.

    Worst charger ever. It takes forever to charge with either port. And charges soooooo slow. Also should have capacity to charge more than 2 full phone charges, but did less than 1.5. Mine came partially charged, so maybe it was a defective return. Either way: Not cool reselling it or it’s just a bad product.

    Pretty disappointed. Had read the reviews so was excited to try it out but I don’t know if it’s just mine that does this but first charge charges up to 70%-80%. Then have to unplug for 10 minutes before I can plug it back to get a charge to 100%.

    I was very unsatisfied with this purchase. This device died on me after an hour of being used even though it's at 85% of it being charged. Also the associates in this Best buy acted as though everything was a joke.

    Charging is VERY SLOW. To re-charge, it is even slower! It drained from 25% to 0% in matter of seconds. No wonder they are on sale!

    The enclosed cord is USB-C. The charger port on this device takes mini-USB. Why would you package this device with a cord that does not charge the device? Rating 1 star for the sheer annoyance of having a device that I now I have to locate a cord that will charge it.
