    This is tough to review for me. There is always an outlet, or car charger, and most places you go have places to charge your devices. Then it happened. A snowstorm that knocked out all the power for miles and miles, 10s of 1000s of people without electricity. The roads were frozen and nobody could drive, even getting necessities, like food and water were very hard to get. We were jumping in the car with one outlet-adapter-charger to charge up so many things. This item became a luxury. It’s nice to have for emergencies, or if you temporarily don’t have a charger. Super easy. The question is how much would people pay to be able to charge their device once maybe twice and that’s it in case of emergencies. It’s a balance of situation or circumstances. Depends on what you do and what your needs are.

    I shopped around forca new charger and I settled for this one. It has qyick charge capability and it is really fast. I like also that it is built like a rock. I have dropped this product on floor and its like a brick. Tough and strong

    I have bought different portable chargers over the last couple of years. This portable charger is amazing! It charges very fast even with two phones plugged in. It also has a longer life. I highly recommend it

    I love how long the battery last, the fact that has multiple ports and it has helped me with so many new USB charger devices that I don't need to connect to a power outlet.

    Mixed feelings

    My prior battery from some generic brand was good. That one was maybe 5000mah approximately. That old one with a usbA-to-usbC cable was able to keep my iPad Pro powered during long zoom calls. It wouldn’t make my iPad battery percentage climb, but had enough to stop its number from shrinking. Then I got this Energizer one. Using its best usbA port and the same cable and the same iPad, my percentage would fall! Only after buying a usbC-to-usbC cable did it perform well. The iPad percentage would even climb during heavy use. So after paying extra money for a cable, I got the expected results that I intended. Let’s say I got mixed feelings on this Energizer battery and with their prior products I bought.

    This is one of the best purchases I've ever made! It can charge multiple devices at once and has a fast charging port! I can charge my phone twice without charging this portable charger.

    Heavy. Haven't had a chance to use it yet. Will likely try to get a smaller/lighter one to carry around with me. Charging now. Reviews seem mixed with several saying it no longer holds a charge after 2 months. Will see.

    It’s a great charger for phones and other low watt devices. If you’re thinking about laptop or SteamDeck, I would not recommend. Because it works best for only for low watt devices, For this price I would look elsewhere.

    This is a great rechargeable battery bank. I primarily bought it to augment my Oculus Quest 2's lifespan, having it in my pocket while plugged into the VR headset. I played for 2-3 hours, and the Quest 2 barely dropped any charge. Following this, I was still able to fully charge my phone twice as well as fully charge my electric toothbrush with it before the battery was in need of recharging. Having power delivery as well as two-way charging through its USB-C port are both excellent features alongside a quick-charge USB port and standard USB port

    Heavy. Very heavy, but does the charge in terms of charging devices. Does seem to get scratched easily and hold its marking so mine does show signs of use already. Takes a while for it to fully charge, but once it does... it works wonders. I love it, just wish it was lighter

    It's a little heavy but it charges fast your devices, it can be recharged with the same cable it comes with, just keep in mind that this cable is quite short.
