    Fairly bulky but works great, charges my phone and blue tooth speakers great. Takes a while to charge the unit to 100%, but it goes a long time between recharges.

    It is a great powerbank. It charges devices simultaneously and fast. The only disadvantages are that it is heavy and it takes a very long time to charge.

    Since I travel by bus and have to sometimes be waiting up to an hour, I use my phone a lot, deleting the battery. I've carried a power bank for years, and my last one stopped charging. I liked that this Energizer one had 2x the capacity of the old one. I also like that I can charge the bank using a variety of cables. However, I don't think it's truly the capacity claimed, though probably close, based on percentage shown after charging my phone a couple times. It's also much heavier than I expected or am used to. A little difficult to carry in a backpack, and certainly not good for your pants pocket

    Heavy at 1.5 lbs. (24oz). I found other power banks of same capacity at half that weight. 30,000mAh is too much capacity for airline travel. Slow charging time. Other than those negative points, it did work well for charging my cell phone.

    No, I would not recommend this to a friend

      Thank you for sharing your feedback about our Energizer power bank. We appreciate your honest review and are glad to hear that it worked well for charging your cell phone.
      We understand your concerns regarding the weight, capacity, and charging speed of the product. At 1.5 lbs (24 oz), the power bank is designed to be durable and reliable, which may contribute to its weight compared to other models. Additionally, the 30,000mAh capacity is intended for users who require extended usage between charges, though we recognize that this may not be ideal for airline travel due to restrictions on high-capacity power banks.

    Capacity is great but charging isn't the fastest. I like that it has more than one method of charging. I would have also liked if you can use the usb-c port to charge devices at this price point. USB-C is only for charging the power bank.

    Had this item for a year, but hadn’t used it yet. Serves a niche for camping during my bicycle tours. Have a USB fan that would always die in the middle of the night. Battery pack worked well, with minimal loss of charge. Only drawback I saw was lack of USB-C output to charge my phone. I didn’t bring proper older cable, since had to charge elsewhere. Seems to be high capacity!

    Packs a punch of power. Easily charges several devices at a time. It's heavy (1.5 lbs.) but it feels heavier. Its sleek and modern looking. If you're going to the boondocks with limited access to electric outlets, this is definitely your charger.

    I bought 2 of these a few years ago and they’re stilling working great ! They are a little heavy but it’s because of how much power it holds so I get it. If you want a lite battery pack, go buy a smaller one that dies quick! This lasts me for daysss and charges up my phone and tablets multiple times.

    Got this to use when camping. Been testing it and it charges your phone fast. Was able to get 2 phones charged for about 4 days. The only thing is the charger itself takes a long time to fully charge. Can't wait to get out into the woods and use.

    Seems to be of good quality but is very heavy for its size. Haven't used it yet, but will this coming week. Purchased primarily for travel and backup during power outages. Charges relatively slowly. Could use better markings for what each port does.

    Impressive battery life and capacity! The Energizer MAX 30,000mAh power bank lasts a long time, making it perfect for extended use. It’s quite heavy and bulky, so not the most portable. One more Type-C outlet would make it even better, but overall, it’s a reliable and powerful charger for multiple devices.
