    Portable power pack

    I got this power pack because my phone is older and won't stay charged. This works very well. It came ready to use and holds charge for a long time. I like that it shows how much charge is available on it when you plug your device into it. It is heavy but I don't carry it all the time so that's not a deal breaker. It charges my phone and has never gotten hot like some do. It stayed cool to the touch. This makes me feel like it is safe.

    The unit was already partially charged upon receipt. While charging it to full capacity, it would only reach 86%. Online research instructed to discharge the unit to 50% and upon doing so, it now reaches 100% charge! The unit has multiple outlets to charge more than 1 device simultaneously. I will be using this mostly for my phone and needed a power bank for times when there are extended power outages from hurricanes/storms here in Texas. The unit is heavy and not petite, BUT, when one needs power, this is great insurance to keep your device operational. If you are looking for a compact, lightweight power bank, this probably isn't for you. So far, I am pleased with my purchase.

    Havent had it very long. Bought it to take with me on a trip. I was gone 8 days and it kept my phone watch and tablet fully charged the entire time. I was at the beach a few days so i wasnt using them all the time. But i am still impressed. For the price i feel it should be that good, and it didnt disappoint! With Heavy useage id guess about 4-5 days before it would be out of charge. I like the mutiple input/output ports it has, however it did take all night to recharge. Included in the photos are the charge\discharge information on the back of the decive for those interested.

    The Energizer battery pack is very simple to use. You can charge it with a micro USB, USB-C, or Apple charger. It outputs to up to two USB cords so you can charge two devices at once. The digital display on the battery pack clearly shows how much charge the battery pack has. It comes with a short USB to USB-C charging cord that was perfect for me since I have a Samsung Galaxy. The charger is about the same size as my Galaxy 9, and about twice as thick. Even though it's large, it is very effective. I would buy it again.

    For my 30,000 mAh 15W, I am still working with this power bank and testing it out. It is a pretty heavy power bank. PRO: Charges my FitBit watch and iPhone pretty quick. Has multiple ports for devices Shuts off automatically when not charging a device CON: The weight (22.2 ounces...1.38 pounds) When down to 0%, took 3 consistent days to charge to 100%. I am not sure if there is a better way to charge it faster...working on that. When charging my FitBit watch, it constantly shuts down and I have to hit the side button to finish charging. It does come with a charging plug, but it is only about 11 inches long. I do like this charger and if you don't mind the weight, I do recommend this.

    This is a great battery. It last long but it should because it’s as large as a mini-tablet. I was able to charge multiple devices without a hitch. Note it takes a long time to charge so do it well before a trip.

    Pro- a physical solid battery. No empty space. Largest battery in compact space vs others, 2 usb Out. Power % display Con- max output is 2amps, only comes with small USB C charging cable no wall plug. Would be better if had 3amp fast charging to device and came with wall plug.

    This powerbank is powerful enough to charge four phones and can probably charge two tablets. Although it is not slim and sleek, it is not bulky and can fit into any ladies handbag. One good feature is that it does not get hot during recharging. With two output ports you can similtaneously charge your phone and tablet.

    Great Portable Charger

    This portable charger is great! It’s a tad on the heavier size but still gets the job done. I am able to charge multiple devices at once and multiple times without having to recharge the actual charger. I have had previous portable chargers and nothing compares. It’s still small enough to travel with as well.

    Always nice to have a power bank that I trust for times when my access to a power source may be limited. I especially like the ability to clearly see how much power is left in the bank. So many charges before I have to recharge the power bank itself!

    Great battery to change several mobile phones, run your Firestick, tablet or iPad (large), great for three/four days before needing to rechange. 2 USB, one USC. To rechange, you can use a Micro or Lighting. This a heavy battery, not light in weight.

    This portable charger is a great charger for someone who needs a lot of power without having to recharge the unit often. It has over 100+ hours of charge time so this one is great for camping for any trip that you will be without a power source for a long period of time. It's a little heavy but holds a lot of power.

    I purchased the Energizer cordless charger based on the name. Although larger and heavier than some, I'm hoping it stands up to its name. I've purchased several other brands, and their longevity and charging times were quite poor. So far, so good.

    I charge this battery pack about two weeks ago before I went on my flight. I read some of the flight rules and learned that I could not bring a battery pack in my carryon, so I just left it at home. Two weeks later, it still shows 100% charged. It doesn’t slow drain light other battery packs. Definitely worth the money.

    It's a solid battery that lasts for a long time. I can get nearly 6 full charges on my iPhone 13 Pro Max before needing to recharge this. The battery charge indicator is great too as it lets me know what percent my battery is left with, so I know when I have to recharge it.

    Not optimal as a vr power pack

    Bought this to use VR gaming. It's a good product, its just not ideal to use for VR, imo. Its a bit too big & heavy to clip on anything or place in your pocket. Assuming a standard power pack is the approx size of a deck of playing cards, this is slightly bigger than 2 decks side by side, and almost as heavy as a half gallon of milk(the best universal items I can think of for comparison). Consider something else if you're looking for a vr power pack. If you're spending the day outdoors and a source to recharge a few devices, this is more than capable and a good choice. Photo is with a few cards for comparison.
