    Love this portable charger which allows us to recharge my phone, my ipad, and my kindle while camping out in the forest with no electricity and without resorting to firing up the generator.

    I've been using 5below banks for a while, while they're good for$5, it's nice to upgrade to a better bank. With the 5below banks, they took 2+ hours to charge, but with this fast charging bank I can get a good amount inb1 hour 5 minutes.

    I bought this to help charge my Nintendo Switch better since a lot of chargers don't charge it as fast as it drains for some reason. This one does it though and does it well.

    Fast charging sometimes glitches. It charges but sometimes fast and sometimes normal. It discharges faster than what states. Could only charge by phone twice before it ran out.

    We use this to power our led lights and from all the power banks we have tried this is by far the best. The battery last a long time before needing to be recharged.

    Must have for those power draining devices. This battery pack allows multiple devices to juice up at once and still have enough juice leftover for some more. I highly recommend this for all.

    I love this charger. It has the capacity to charge multiple devices out in the field. I have developed charge anxiety over the years and this battery takes the fear away. It is solidly built and at first, I had reservations until I remembered Energizer has been making batteries for decades. It fast charges my Note 9 even on the "slow" charge port.
