    Good product, great capacity

    I purchased this product due to 1). The capacity and 2) the Energizer brand. I believe that Energizer would select quality cells (for both safety and long life) for their products. The instructions were unclear and too brief. I was confused with the flashing display and to press or not press the one button. My iphone did not charge reliably with the wireless charging option when it was in the case. This charger requires removing the case which I do not have to do with my two other wireless chargers. The capacity is great. It is capable of charging my iphone and my ipad twice each.

    I just love it. I’ve been using it so far charged my I phone three time and the battery can take at least two more. I would recommend it to my friends and anyone.

    Cannot move the phone when charging wirelessly

    I returned this item because it charges wirelessly but it does not "stick" to the phone, the phone basically needs to stay still in order to charge. We could even charge it when we were in the car because of the movement. We were expecting a charger that we could attach to the back of the phone (magnetically). Otherwise it worked fine.

    No, I would not recommend this to a friend

      Hi AngelicaR,
      Thanks for clarifying your expectations. Based on the product sheet, this model (QE20010PQ) is designed for Qi wireless charging only and does not include magnetic attachment. The features highlight “wireless charging up to 15W” but make no mention of MagSafe or magnets. That’s why the phone needs to stay still on the pad for proper charging. If you need a charger that sticks to the back of your phone, look for MagSafe-compatible magnetic power banks instead.

    Having magnetic charging would be better so you don’t have to think about whether the phone is charging or not.

    Decent battery but slow wireless charging

    I bought this power bank mainly for travel, and overall it works okay but not great. The wireless charging is slow and sometimes doesn’t connect properly unless I adjust the phone position multiple times. The wired USB-C PD charging works better but still doesn’t feel as fast as advertised. The battery capacity is good and it can charge my phone a couple of times, but the unit is a bit heavier than I expected. The LCD display is helpful, but overall performance is just average for the price.

      Hi SSrivastava, thank you for sharing your experience. Wireless charging can be slower and require precise alignment compared to wired PD charging, but it should still perform reliably. If the speed feels much lower than expected, the unit may need inspection. Please visit https://support.energizerpowerpacks.com/ so we can assist with troubleshooting or replacement.

    Worked really well for a trip my family just took. I would definitely buy a 20k over a 10k. This model has a digital readout of % left as well.

    After using this product for over three months now, I can say it was worth buying. It has good quality and charges quickly. The one issue is that it takes more than three hours to fully charge, but this is understandable given the size of the product.

    Product works well. The battery is big enough to charge several phones at once to full battery. (From about 20% on 2 iPhone 15 Pro Max phones) Had plenty of battery left for a future charge.
