    So far great! It's a heavy charger, but it lasts for a while. Charging the battery takes several hours, but the amount of charges you get from it is worth it.

    Has lots of power to charge for days without running down. I charged many different devices on vacation for 4 people and on the 5th day I had to charge it back up. Its picky about the cord you use to connect, so high speed cables are prefered for faster charges. The cheaper ones work, just not as fast. It's a bit heavy so I used long cords & kept it in my backpack. It's well worth the money.

    Although it is larger than most power banks and kind of heavy, I really like that it has 30,000 mAh power for charging multiple times.

    This thing is a beast! I'd say it charges slower than I would like, but that may be the cord/charger/outlet we were using and not the unit itself. Given its capacity it still charges fairly quickly. And the capacity is AWESOME. It charged a camera and 3 phones and still had about a 30% charge left on it. We had it for a week in Hawaii and never needed to recharge it despite using it frequently to charge our devices. Highly recommend!

    The Energizer MAX 30,000mAh Power Bank proved to be a reliable travel companion during my recent trips outside the US. Its 30,000mAh capacity provided ample power to keep my devices charged multiple times, while the LCD screen kept me informed on battery status. The fast charging and sturdy build make it a trustworthy choice for anyone seeking a high-capacity power bank on their travels.

    I bought this with hurricane season in mind. Laat year we were without power for a little over a week. We have a small generator to run the most important appliances, like the fridge, freezer and some fans. My boyfriend's little batter pack gets maybe two charges before it needs charged. Ive charged my phone 3x, my tablet 2x and my watch at least 3x before I needed to charge it. Its a bit bulky and heavy but it's well worth it in my opinion!

    Very good battery life, weighs a lot, wish it had more usbc ports but very good considering the life of the battery. I wish the usbc cable would fit perfectly, but seems to easily slide out.

    [Employee of bestbuy] The title speaks for itself. The device has a huge amount of power storage. It has extra ports to charge multiple devices and can charge them several times over. On the last full charge I was able to charge my iPhone 14 Pro Max to full over 5 times before this device was empty. It charges quickly and is very easy to use. Highly recommended.

    [Employee of bestbuy] this lithium Bank is part of a gift for a college student. I dragged my feet on purchasing one of these, after my first hand account of other inferior brands during the release of a very popular trading card game app several years ago. yet, after this item flawlessly charged a laptop and phone during a courting date and while casting to a larger screen. it's safe to say this is a staple for them. also the numbered display is very nice.

    [Employee of bestbuy] Big battery. Only issue I have is that it takes a long time to charge. Even with a PD charger. But it will last for days. Will charge my Galaxy 22 Ultra 5 and Buds Pro times before having to charge it up again. Would give it five stars if it charged quicker.

    Battery life lasts long but this thing is Heavy. You can not fit it in your back pocket like some of the smaller ones. It I needed something with a lot of juice that would charge faster than my older smaller battery pack. I still have the smaller on though for when I need to carry one with me.

    Big and a bit heavy but works well for charging multiple items. Charges pretty quickly if you plug it into a USB-C power supply with 20 or more watts. As noted in other reviews it won't charge to 100% right out of the box but if you draw it down to a low charge and then plug it in then it will go to 100%.

    It's a brick, a good brick. A battery brick.

    Without sounding too flippant... It's a charging brick. What do you want? It works perfectly. Charges with either USB, USB-C, Micro USB, or Apple's special cord. It also has a numerical value for how much battery is left so it's helpful to gauge how much is used to charge something fully. For example, charging my iphone12 only takes 9/100 of the battery so I can fill my phone battery 10 times over in one charge.

    I have only used this item for a short time. So far it is working well, but I was worried in the beginning when charging it because it was stuck at 84% for quite some time and I thought that I might need to return it. It took a few hours to completely charge. This battery pack is quite heavy.

    Great Large Capacity USB power bank

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

    This is a hefty USB charger that can charge several cell phones at once and it still has most of its charge. The downside would be taking several hours to charge if it's low. It's a bit heavy and might not be a good choice to keep in the purse for a phone emergency charge. This power bank would be great to take camping, hiking or keep on hand during an emergency situation such as a hurricane resulting in power outages.

    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.

    As a massage therapist I always bring music to my clients homes. I also use the DigitalClock on my phone. Which eats up a lot of my battery. I purchased this to make sure I never have a low battery on my phone. It works fantastic. I love the digitaldisplay so I know how much battery life I have. Highly recommend if you’re somebody on the go.
