    Pokemon Go Fest New Jersey 2025

    Bought this for Pokemon Go Fest. It works really well, even if it is bulky. This battery is allowed on Allegiant airlines since it is less than 28k mAh, but it isn't like they checked my batteries. This battery feels sturdy and it lasts for a while, especially for Pokemon Go. Pokemon Go drains a lot of phone battery, so this battery pack does the trick.

    Best charging block for the money. We were able to charge all our phones with a rapid charging cord very quickly. It charged back up pretty quick so we could use it again on our next excursion in Hawaii. We took so many videos and photos we needed that charging block to be ready to go!Will never go on vacation without it.

    Great charger. Bit bulky and capacity went down to about 80% within 6 months. Size is too big for the realized capacity of this battery.

    Great power bank! This Energizer 20,000mAh charger is super reliable. Charges my phone multiple times and even works well for tablets. The LCD screen is a nice touch, showing exactly how much battery is left. A bit bulky, but worth it for the capacity. Great value for the price!

    Excellent product. I primarily use it to power LED lights and a small fan in the rooftop tent in my overland vehicle. It has enough power to last all night. Additionally, if I fully charge it and then dont use it for weeks on end it retains full charge.
