Customers are saying

Customers enjoy the Ultimate Lithium power bank for its fast charging speed, especially the wireless charging feature, and long battery life. Many appreciate its portability and overall performance, finding the LCD display helpful for tracking battery life. While the size and port count are also seen as positives, some customers find the weight to be a drawback. The price offers great peace of mind.

    Helpful but I imagine there’s better. If you’re not using a cord the charge is slow and you have to get it positioned “just right”. Better than nothing though

    Not info on the package. Did not come with an outlet charger and the connecting end for an outlet charger did not fit what we already had. Will not have to purchase an outlet charger just for this item.

      We are sorry for the frustration and inconvenience caused by the lack of a wall adapter and the confusion over the cable. We understand your disappointment that the included cable didn't fit the charger you already had. To recharge this power bank, you'll need a USB-C wall adapter that supports Power Delivery, as this allows for the fastest charging speeds. We apologize that this was not made clearer, and we appreciate your feedback on the packaging information.

    It's a handy powerbank. I like the most is the wireless charging and USB-C output. I can use both.

    Good product, great capacity

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

    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.

    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.
