    Purchased for my wife for Christmas 2022. Lasted just a few days past the return date! It never dawned on me to get an extended warranty on a power bank! Energizer support and warranty is absolutely useless... i ended up get my wife an Anker. I have one anker power bank that is well over five years old and still works! I guess Energizer just needs to stick to making regular batteries!

    My I purchased this power bank based on my experience with another Energizer power bank. Great for trips where AC power is not available or is limited. I use it to charge my mobile phone and tablet. They seem to go forever.

    This thing hold so much power. We had three cell phones charging from it for about an hour and all three were at 100% . Bought one last year for our disney trip and bought another one this year for our disney trip for the rest of the family to share. Highly recommend.
