    I use this when I go camping, comes in handy for my phone and charging a portable fan for the warm nights! It is pretty heavy but worth it for me.

    Hand straps thin but works great otherwise

    The hand strap broke/tore off almost immediately. It’s got some serious weight to it so it would have been nice to have a strap that didn’t break so easily and immediately. It takes a longgg time to charge BUT once it’s charged it works very very good. Charges my phone fast and I still haven’t had to recharge it yet. If the strap didn’t break/wasnt so thin and flimsy, would have gave it a 5

      Hi Madison,
      We appreciate your honest feedback! The strap issue sounds frustrating, especially for a power bank of that size and weight. We’ll share this with the design team for improvement. For the long charging time, that’s expected with a 50,000mAh capacity, but it’s great to hear the performance once charged is excellent.

    Its not too heavy and seems well made. At 30w charging it takes about 7-7.5 hours to charge. This charged my 11,200 mah tablet battery from 0-100% pretty slowly, 4 hrs, but there was still 70% left on this power bank, thats insane! If i had a complaint it would be it doesn’t show how many watts its inputing or outputting. Other than that its been great so far. I haven’t owned it for long but I hope it lasts for at least 2 -3 years

    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

    Good portable.

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The portable is pretty good, it takes a long time to charge but that's because it won't go down fast at all. The only issue's I've seen are that my phone battery won't go up, but it also won't go down at all. The other issue is the weight, but that's to be expected so I didn't let it affect my rating. Overall, good for someone who's out a lot and needs a long lasting portable, don't expect it to actually charge your phone.
