    We bought this to use at a convention where there was potential for heavy iphone 11 use. It's a little heavy for my liking, but I guess all power banks are. It takes a while to fully charge, probably around 8 hours, starting from 19%, which I'm not sure if that is standard for a power bank or not. I like it. It is handy to have and we're already making use of it for times other than the convention.

    Is a little big but not heavy, and i love it. Takes a while to chargw so i put it overnight but the battery lasts a long time. I traveled from colombia and it was a very long trip due to delays and i charged 4 phones and still got home with 29 %. Also when hurracaine Milton we lost power for 3 days and for 2 days this was our saviour . My daugtber charged her laptop and was able to do her college work. And we also used it constantly for our phones. I bought 3 of this for myself and my kids and am going to buy a 4 th one for my other son.

    My first time using one, works great. Charges up a little slow but holds onto power for a long time. If you're traveling, just note that it's pretty heavy. I carried it in my backpack and well, you can definitely feel it. Otherwise than that, it was great and reliable.

    I was skeptical to get this after 3 portable charges. Which were wasted and not able to return or was able to return it. I had to get another one last time before I gave up. This one, better than anything else! I had to wait to let it charge for 6 hours I think but after that this battery will last you a week! I used this when we had a 3hr trip and battery still at 80% of use. Didn’t go down after 10% by the end of the trip (have 4 phones one of each of my family, need to be charged and all iPhone :,) ). Still a great buy and my parents still use it till this day I believe after a year now after purchasing this portable charger.

    So far, happy with the purchase. Having the portable charging capability works great for our lifestyle of being 'off grid' for days at a time. Also, using our dog collar tracking system uses lots of cell phone battery and need to have the power back up, just in case. Charging the battery pack seems to take a long time, but time to recharge the phone seemed to charge fairly quick. Looking forward to seeing how long the power bank lasts.

    This thing works wonderfully. I play on my oculus quest 3 and I have tried so many different battery options and every time they just fall short. if any of you have an oculus you understand that charging never charges it just slows down the time it takes to die. But this? My lord I would be at 10% and it would charge my oculus up to 100% while in active use. I can charge my iPhone up to 4 times as well. It does take a really long time to charge so make sure you plug it in before you go to bed. otherwise this thing is amazing.

    Excellent device; Charges to full power in a reasonable amount of time and holds the charge very well. It is a little on the heavier side but that was not an issue for me and worth the reliablity.

    it’s heavy well make, hold charge, I have similar unit without LED power level indicated and USB-C connector for 6 years still hold charger all way with me every time I travel by air. Cost about $5 more than Energizer make in China, Anker - Power Bank (20,000mAh, 15W, 2-Port) must better on Quality. Love it.

    While I hate to admit that this charger is extremely heavy and feels bulky, it works great and charges my iPhone relatively quick and still remains at full power. I’ve used this charger to power fans, speakers and flashlights as well as a mini vacuum cleaner and multiple rechargeable closet lights. It truly is an awesome charger and I would not hesitate to purchase it again.

    I travel for work, have 2 phones, a tablet, and a smart watch. I keep this in my backpack for emergencies. In the last 2 weeks, I have needed to use it to fully charged my watch twice, my IPhone 13 once, and my Samsung S22 Ultra once. It still has juice left it in. There is a digital display with the battery left. This only turns on in charging mode. There is a USB C and a USB port. I wish there was an additional USB C so i could charge 2 phones at once, aside from that, i charge it once a month and have it works for my needs.
