    I needed a good quality portable charger for my long hikes to keep my iPhone charged. 20,000 mAh is overkill but this Anker is top rated, has an 18 month warranty, is at a great price, and can keep my entire group charged. Great for road trips too.

    Can charge my note 8 3 times and keeps me going for the whole day despite too much video streaming for podcasts.

    Bought this in November for my Bday trip to Florida. Was in such a rush and a panic ( first time flyer and i was getting right off work ) ended up pulling it out of my bag and leaving it in the car. Didn’t realize it until i got to Charlotte and spent my whole 20min flight taking a video which killed my battery. HAHA I try and keep it in my purse now but it takes so long to charge that I dont use it often.

    I would buy this again, it stays with me and my Note 8, but it can charge two phones or whatever at the same time. There's only one port for fast charge and the second is normal. Too bad there's no USB-C on this model, but I am buying another one from Anker

    Bought this item on the recommendation of my son-in-law. He knows all about the tech stuff. I haven't really had a need for it yet but based on what he said I will be satisfied with my purchase. The idea of having a portable power supply is nice!

    Not intended for the Switch though, there’s a special version of this that won’t brick your console.

    Great power pack that easily fits my every day carry bag. I’ve used it to charge phones, tablets, drone remote, and even my DSLR camera. The fast charge USB port is REALLY fast. Would highly recommend to anyone looking for portable power!

    This device does what I purchased it to do, which is primarily to charge my phone while I’m mobile and don’t have the access to a charger (i.e., going for a hike, taking photos with my phone). Definitely recommended for people always on the go.

    If you don't use the IQ output, you're good. The regular USB output charges my phone fast even while I'm on my phone. The IQ output however is terrible. I try charging my Samsung s9, it'll charge for a little bit and then stop. Nothing I did would keep it charging until I switched the cable to the regular USB output. It's a shame because I liked the idea of the IQ. Too bad it doesn't work right. This charger is also great for switch owners.

    Bought this product based on the other reviews and they were not wrong. The charger does a great job for all charging needs. It does take at least 24 hours to fully charge it for the first time so make sure to plan ahead for that.

    I bought this for my daughters 16th birthday for one of her gifts. She absolutely loves it and says it doesn’t have to constantly be recharged since it has such a high capacity. I’m actually going to bu one for myself now!

    I am prepared for any power outages that may occur in my area. This particular item was recommended to me by a friend and I’m certainly glad that I was able to purchase it and have it if and when a power outage occurs.
