    Love this thing, well worth the price. I just moved from FL to CO and this was perfect for the drive. I made sure to charge it every night at whatever place I stopped, and it never died on me during the journey. A++.

    This actually surprised. I knew it boasted being a quick charging device. But in the minimal time I used it, my phone was completely charged compared to my old portable charger. Better 35 minutes than a hour and 20 minutes.

    This was a Christmas present for my mom because her phone is always dying. It works very well and she loves it. It does what she needs it to do when she’s out on the field and needs to use her phone. My mom’s very happy with it.

    Decent price! And a good size. I gave it as a gift but the person seems really happy with it. It came in handy to charge his cell phone during the week when he’s away from home and unable to just get up and plug in his cell.

    This was a great thing to bring with me during my trip to NY! Being that you spend majority of the day walking around and not having time to stop to charge your phone it definitely comes in handy.

    I had before the 10,000 mAh version which was empty after charging two phones. This one has a higher capacity of 20,000 mAh. The counterpart is that it is heavier and bigger.

    We purchased this battery pack to use on a long road trip with 3 adults, two teens and a toddler. It worked great for keeping all of our entertainment powered up and thus keeping us sane for the 26 hours we were in the van.

    Holds a charge for several months. After a flight cancellation at an airport, was trapped in line for six hours trying to reschedule. Backup power while standing in line was a great stress relief.

    Power stations that I’ve purchased on eBay has always been a disappointment. They NEVER deliver the output that they’re advertised to do, and battery fatigue occurs far too soon. The Energizer has been only IMPRESSIVE.

    Terrible power bank

    I would not recommend this power bank. Main reason it doesnt charge your phone fast at all, it literally takes hours to even get a charge let alone maintain the charge you have. The battey may last awhile but again you would have better luck charging it using via wall plug or your car port. Wouldn't recommend.

    No, I would not recommend this to a friend

    Energizer mobile charging battery

    I would like to briefly state that this is a very good mobile battery charger for all your small android devices like your phone and tablets. It is a very necessary item, because in 2019 my family and I had to deal with some tornadoes here in northwest Dallas, TX and our local electric transmission company left us without electric power for about 48 hours. Therefore we had to charge our devices using the electric power from my steddad's SUV battery. It has 2 USB ports for your USB charging cables, 1 USBC charging port, and another small port for the mobile battery's charging cable.

    I purchased the Energizer phone bank just in case I lost electricity during a winter storm. It comes already charged most of the way. It has stayed fully charged and ready if I needed it. It gives a peace of mind.
