    Love this Energizer Portable Charger. Fast charges my iPad and phone quickly without draining the charger, has a lot of charges for my iPad and phone. Lost count on how many charges it has but it’s plenty. Take it with me on trips to family or just riding along just in case my iPad or phone charge runs low. Highly recommend this Portable Charger.

    This power bank is a beast! 50000mAh is no joke, it charges my phone like a dozen times before needing a recharge itself. Totally worth every penny, it's a lifesaver on trips and during power outages. Highly recommend it to anyone who needs a reliable and powerful portable charger. Seriously, buy it, you won't regret it!

    Ive had this for about a week. I havent used it for anything but charging my cell phone. But ive only charged it once since purchase and have used it to fully charge my phone 6 times before having to recharge! Amazing product that actually can be called a useful portable charger

    Great! Much better than the old Energizer 30k mah I used to have. That thing was so SLOW and drained fast. Took a full DAY to charge from 0 after use. But only lasted probably 3-6 hours charging. But this one. Much better. Charges fast. heavy but robust. People ask me what is that a portable battery?! Haha I definitely Will get another one eventually.

    The charge it holds and the amount of devices it can charge is unbeatable. I took this to flordia for a disney world trip and was able to charge multiple devices from completely dead to fully charged all throught out the day.

    technically too high capacity to fly with but TSA does not seem to notice or care. positively ridiculous amount of charging power kept me fully charged the whole week i was in vegas for wrestlemania. handle broke about two days after i got it though so i can't give it a full 5 stars but it looks like i should be able to replace/upgrade it with a standard camera wrist strap so no worries there really. also, it is a bit heavy/awkwardly shaped to carry around or put in a pocket so if you need to go somewhere with a no bags policy this ain't great

    If you need to take this on the go better wear a back support. It's heavier then a bowling ball. Nobody could snatch your purse and run off for sure.
