    Great device needed for a 13 hour drive for my IPhone Pro13 and the t wired great. I changed it up. I like how it lights up to let you know how much charge you have. Of course I still had a full charge after my 13 hrs because it get’s 48 hrs on a full charge. I am very satisfied with this purchase.

    I've had this product for the past 3 years, and I must say, it works incredibly well. Its got a good amount of storage in the context of how much it'll charge up your phone. Definitely recommend for long travels/road trips.

    Quality battery pack from Anker. Slim and easy to carry, with a solid 10,000 mAh battery capacity. Add a great 18 month warranty and it's a really excellent choice. Charges the my 5,000 mAh battery in my phone twice on a charge. Great price at $19.99 on a Best Buy Deal of the Day.

    Slim: Portable. Comes with one, short standard USB-C cable, and that’s it. Luckily we have extra USB to Apple Cables available. I can probably squeeze in about two charges for an iPhone 13.

    Best Power Bank Ive Ever Used

    This power bank out does all the previous ones Ive owned by a LONG shot. It recharges my phone in a decent amount of time while still retaining a significant amount of juice. As someone who works a job that involves me being on the road quite often, this power bank has been wonderful. The way Ive managed my phone's power, on a five day work week, Id have juice in this power bank that would last me for 3 of those days on average. Would definitely recommend if you're looking for some extra back-up power for your phone when you're out an about. Ive also used it to charge my Bluetooth headset and it works well with them too.

    bought this for a couple of primitive camping trips we have coming up and an overnight stay on a WW2 battleship with limited power options. The first night I got it we ironically had a power outage at home and my phone was almost dead. My phone charged back up to 70% in about 30 minutes. Seemed faster than charging in wall plug...maybe not. Very happy with the two times I have used it. Only charged up Anker when I first got it. Still has plenty of charge left. My wife is still happy with her older model as well.

    Charges extra fast and has at least 2.5 full charges in it. It’s extra thin and small so it fits easily in small pockets

    Works well. Have charged my phone and deivces to 100% with no issues. It is the size of a medium sized smartphone but i knew that when i bought so I'm cool with size. I throw it in my back up and forget about it but ut is always there when i need it. I've taken on camping trip, concerts and other events when you know you may not have access to electricity.

    Overall, the device does what it should. It's very slim and sleek and also comes with its own carrying case, which is a nice touch. I am able to fully charge the device in a few hours and can charge most of my devices (cell, tablet, etc) fully. Anker is a great brand and this device is no exception.

    So far, the battery charger has performed well. I was looking online at Amazon for one and didn't want to spend a lot. However...Amazon had all of these crazy mfg's I've never heard of...so when it comes to my phone that I paid a $$$$ load of money for...no way was I going to risk some off-named mfg battery pack to fry my phone. Love Anker's products. This pack is exactly what I was looking for, compact, and I get 2 full charges off of it for my Samsung S20.

    Anker does not disappoint with their products. This powerbank lasts for at least 2 full charges and it charges up pretty quick. It is a reliable brand and powerbank. I have no issues with this product and I would def buy Anker again.

    Overall, this is a really nice portable charger for travel! It’s not too big, and it charged really fast for me. I just wish it had a USBC plug that wasn’t just for charging! I used it while flying from America to Japan, and while I wasn’t using it 24/7, it kept my phone charged the entire time! I still use it in Japan, and it’s still reliable!
