    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.

    I do “gig” work full time right now, and my car charger does not work. I heavily rely on power banks, and have tried quite a few. If this model was a little bit lighter it would win hands down. I love the number display with accurate battery percentage remaining in the bank. Sometimes I have to carry it along through a store, and with the weight of it I’ve dropped it a couple of times with barely a scratch so it seems durable in that aspect. I feel like I’ve put it to work for a couple months now and still charges both in and out just as strong as it did new so it seems durable that way as well. If you don’t have to carry it around it is a great power bank at a decent price.

    I bought this power bank before my trip to Japan and it saved me! I had an older one (brand unknown) and it would die out so fast! But this was easy to use and kept the charge! For someone who was constantly on their phone for maps and translating, this power bank was great! The only thing is, it is a little on the heavy side. But for me, it did what it was bought for, some I'm thankful.

    I bought this charger for backpacking in the backcountry. I love the power/recharges held in this unit. The digital readout on power remaining is so much easier than little blue dots to determine how many more charges are left. In backcountry backpacking every ounce counts. The hefty one pound weight is my only concern. If this unit is to be used at home, car camping or any other activity that weight doesn’t matter, then this is you product.

    My iPhone was out of charge after an hour Zoom meeting... the Power Bank prevents the phone from dying before the meeting is over! It's great!

    This power bank is literally a power house. We went an entire weekend topping of battery life on 3 cell phones. My daughter uses them when she has dance recitals so she doesn't have to be locked to a wall outlet in a strange green room. I bought two, 1 for my family and 1 for my father. He was hesitant about using his, but he charges it overnight and uses it to charge his E-Reader. Definitely recommend this product.

    The size might be a problem, but overall great usage. I bought this for my trip overseas, and it never once died on me kept my phone charged never overheated and rarely had to charge the actual power bank. Only thing is that the size is huge but it’s perfect for when you go out and you have a bag on you Overall for the price and for how long you can use it extremely underrated product.

    it has worked really well. Fully charged two phones from 5% to 100% before running out of juice. Its a bit bulkier/heavier than expected, taking up more space (pockets, bags...), BUT charging capacity is GREAT

    Originally I wanted to use this for my tablet but it needs to be left off in order to charge other than that it charges really good, very bulky I think it’s Best to just use it for phones

    This battery has a very long life. The very simple display shows the percentage of life remaining and is incredibly useful bc that's all you need to know. It connects via both USB and USB-C to support a variety of electronics. The only limitation I found is that I tried to use it as the source for a small LED light. The current draw was too small, so it kept turning itself off, lol. Obviously not it's intended use, but I tried.

    This portable external charger is amazing. It holds a charge for at least two days after i have used it 4 times eash day without having to recharge it until the third day and it recharges super fast to 100% from Zero within an hour to 75 minutes. I talke with me on vacation and daily when i am out all day on public transportation, knowing that i can depend on all my devices will be ready all day. Great investment
