    I bought this item due to the brand Anker. I read the reviews online from customers who have purchased items from Anker and they were very satisfied with their products. My relative has a smaller portable charger and she is very pleased with it. I also like the idea of the nylon carry bag that allows me to place the charger and cord inside the bag so it will not be damaged.

    This works great with my Samsung note 9! It does have the fast charge capability and that's a plus to the size of the note 9's battery. The price is right on point for what your getting. I like the mesh, kinda padded, carrying case that comes with this power bank. Its mesh material does allow the battery to "breathe" while in use or when your recharging this battery.

    This was my travel buddy for a long time. Got me through many flights. Overseas, did wonders making sure my devices were powered, keeping me online, and thus keeping me safe. Can't stress enough how important having auxiliary power is even during daily life. This is a great option for longer travel. I'd use a smaller powerbank for daily use.

    I was looking for a good portable charger to use while I’m at work. Since I prefer to have my phone by me at all times instead of leaving it somewhere by an outlet. It takes a bit to fully charge since I’m using the Apple block. But it lasts a long time it’s been 5 days since last full charge and it’s still going strong. It doesn’t come with it’s own charging block. The cable is included.

    I had the older version of this charger, but you know what happens when you let people borrow your things.. Yep, they loose them. Bought this one on sale, and it’s better than the one I had.. super happy to keep this in my car in case I end up somewhere that I need to charge my devices. I get many charges without having to constantly having to recharge the charger.. thank you Anker!!

    This is a great product. I have owned portable chargers before and they dont last very long and are horrible at charging. I have owned this for almost a year with no issue. I even bought a 2nd one in 10,000 mAh. It does take 12 hours to fully charge so keep that in mind, but it will charge my phone several times between charges. Highly reccomend!

    I bought this on the recommendation of a BB sales associate and couldn't be happier. I needed to replace a 30k battery pack I've had for years as the ports had finally worn out. Dual USB ports, 1 standard and 1 quick charge. Solid, well made and doesn't take forever to fully charge. It's not small in size but considering its capacity it's not overly large either. Great price as well.

    This is a great portable charging device. I have used it for about a week and it works perfectly. I am always on the go and not always able to leave my phone on the wall charging somewhere for fear of leaving it. I can put my phone and the charger in my pocket and have them both close by when I need to do something. The fast charging is the same as having the device plugged into the wall.

    Anker makes a bigger battery, 26,800 mAh, but this one is plenty big enough. I even got a usb a to usb c cable and use it to charge my laptop. I have never had this thing run out of power on me. The only bad thing I have to say about it is that it takes a long time to charge up. However, so long as you plug it in overnight, you should be fine based on my experience.

    I am very satisfied with this device. The gentleman who told me about a few others which were more expensive, yet still did the same thing, always came back to this product. I am glad he gave me the knowledge I needed to make the right decision, because I love it. And you get a case with it. Super easy to use and slides in anywhere! Happy customer right here!

    I’ve used this portable charger for several weeks. I can get 5 full charges to my iPhone from one charge to the portable charger. It is a bit heavier than the less expensive models, but the power output is definitely worth the extra ounces. I am pleased with its performance. I purchased a Warrenty through Best Buy. Time will tell if that was necessary or not.
