Customers are saying

Customers frequently mention the convenience of wireless charging and the long battery life of the Ultimate Lithium 20,000 mAh portable charger. They appreciate the LCD display that shows the remaining power and find the charger easy to use. However, some customers find the charger to be heavy and a few have experienced issues with the battery life and the charger stopped working after a short period of time.

    I purchased this charger less than two months ago and a few days ago, I noticed that the display shows gibberish on it. I can't tell if it's 100% full or how low it is, because it shows weird stuff on the display, like the "Predator" LED display on his forearm...luckily it still charges, just don't know where it's at as far as remaining charge. I only used it like three times, very lightly, mainly to test it...no bueno and I can't return it any more.

    This 20k power bank should be able to charge my phone (5k battery) multiple times before needing to recharge. I didn't even get one full phone charge from it. Would not recommend.

    Actually planning on returning this. When I applied my husbands phone to the battery pack it drained to zero and took days to get to 65%. And it’s heavy.

    I bought this because I had a trip coming. I used it before the trip and it worked. During the trip I only got to use it once before it just stopped working. Tried rebooting, recharging over night and nothing. As soon as I returned from my trip I returned it.

    Doesn’t hold a charge. I have only had 4 months and used a handful of times. Shows 100% charged, leave unused and by morning it’s dead. I waited too long to get a refund.
