    Solid well made brick. This has held 100% charge for a week. Charges iPhones rapid and still have over a 50% charge after two uses.

    rarely write reviews, but I had to make an exception for this power bank. It's by far one of the best purchases I've made. The build quality is excellent, it's compact yet powerful, and it charges my devices incredibly fast. Whether I'm traveling, working remotely, or simply out for the day, it gives me peace of mind knowing I won't run out of battery. What really impressed me is how many full charges it can provide before needing to be recharged itself. It's reliable, durable, and performs exactly as advertised—if not better. If you're looking for a high-quality power bank that delivers on performance and convenience, look no further. I highly recommend it!

    Fully charged both my phones in under an hour and the power bank still had over 70% charge. Only downside is the size and weight, but it fits perfectly next to my MacBook charger.

    You can get about two and half full charges off of a fully charged box so I usually go three days without charging up the power box. Only thing I would say is that if you want to carry it you better have some big pockets.

    Very reliable. The percentage full indicator is great as well as the trickle charge function. I like this power bank for its capacity and also for its simplicity. The attached usb-c to usb-c cable is very handy and I think more reliable in the long run than a built in cable.

    Excellent power bank. Can charge my phone multiple times & it will also charge other items like an iPad, watch or tablet. I have not used it for my laptop yet but I feel that it would be able to charge it without being too slow. Best part is it comes with a USB-C - USB-C charging cable that attaches as a strap. You can see it in the photo. Honestly the only downside is it’s slightly heavy. It will still fit in your back pocket. Highly recommend.

    I use it alot, its bulky and heavy...wich is fine, but it drains awfully quick, idk if i got a dud but my buddy has one a forth this size that last 3 times longer, he let me borrow it when a tree ripped my power lines out....anyways i had higher expectations, charge this thing just as much if not more than my phone, wich kinda defeats the point of it i was hoping to ge able to charge my phone more but it drains so fast i have to keep both these on the charger now. Still it comes in useful many times and i do use it almost everyday and bring w me on occasion so its nit a bad device just heavy and for the size it should hold more juice imo

    This thing is a beast! I use it to charge my Samsung S24 Ultra mobile phone. I use the app "Ampere" to measure the amount of charge it puts out and it showed upwards of 3500mA on average abour 2900mA with the included cable, which doubles as that strap that you see in the product image. This is super fast! I can't complain. Another good feature with this Power Bank is the display screen of the charge level of the battery. It'll show you how much percentage of "juice" is left that it has to allow you to charge. It does have a USB A and two USB C ports. The Power Bank is smart enough to know if it is plugged into another device (Phone, Tablet, or other) or if it is plugged into some kind of wall outlet for Power Bank recharge. The only down side to this product is that it is a little bulky. Make sure you read the specs in terms of size and weight. I just put it in my backpack and run the cable out of it to my device. It doesn't get 'hot' as it charges. It does warm up slightly but nothing of concern.

    We were going to Italy and needed to be sure to have a portable power bank to take with us on our outings for our electronic equipment. This little baby did an outstanding job keeping all of our gear charged for the entire duration of the trip and we only had to recharge the power bank once. Would highly recommend this for all of your hand held electronic equipment.

    It's great for when you are on the go and need to be working on your phone, or if you have kids it recharges my phone more than 4 times on a full charge, also it recharges pretty quickly great job Anker.
