    Charges my phone fast. The battery pack last for days demanding on how much you use it. I like how heavy duty it is! I’m not afraid if I accidentally drop it will fall apart.

    So far so good. It's light enough and thin so it easy to carry. Hopefully it will continue to be what I need when out and about.

    Charges quick and charges my device well. I am happy with my purchase and would recommend it to someone looking for one. The charge lasts for quite a while. I used it a couple of days without needing to charge it.

    If you’re taking a trip to Disney or a trip period, this bad boy comes in handy! Charged my phone from 2 percent to 98 in an hour. I definitely recommend this device. Can also fit in a small purse.

    If I were to die and be reincarnated as a portable charger, it would be this one. Not too big, not too heavy, but just right for fitting in my pocket while walking around the zoo.

    I honestly love it. Has a long battery life. You don’t have to turn it on for it to charger your device. It also knows when to shut off so the batter power won’t go to waste. Look no further, this Energizer portable is the one!

    This portable charger will charge my Samsung Galaxy s10+ twice and still have enough juice to charge my earbuds. Good price, a little smaller than my phone, and not too terribly heavy. I recommend it

    quick charging with multiple ways of charging and charging the power bank at the same time. The charge holds for a long time and the speed at which it charges my devices is better than some direct outlets.

    The description on this portable charger is misleading and false information, based on my experience. I purchased the 15,000mAh, which says BOTH on the box and in the product description that its rated 54hours of charging. This is NOT the case. Out of the box it had 2 bars batter life, charged it to the full four and it took about 4 hours. On a FULL charge, I decide to test it out charging my phone. I have a regular 6.1 iPhone 12 pro; I was charging from a 40% battery range. When it was close to 100, the portable had lost a bar. Since its rated at a 54 hour charge for smartphones, it should be about a 12 hour charge per bar. My phone did not take 12 hours to charge. My wife also charged her phone, an iPhone 12 pro max. She was from the 30% battery range. The portable charger now dropped 2 bars. In the span of ONE DAY, the charger was already used up and needed to be charged. On the good side; it charges fast but not blazing fast, its hefty which should mean good battery life and material?, its slim, small enough to carry, and it has a good charging variety meaning 2 USB entrys and two others. Still, I’m very disappointed.

    Works great and charges devices fast. Fairly light for a 20k. Used in traveling and charged 2 iPhones and an iPad at the same time, lasted me an entire day of regular use of all 3 devices.
