REDSHINE Ultra Slim Power Bank 8000mAh Portable Charger Lightweight External Battery with Fast Charging for iPhone X/ 8/7/ 6/ Plus/ 5/ SE, iPad, Samsung, LG, Google Pixel and More (Black) (Black)

I absolutely loved this product at first. It fit great in my purse, and charged my phone as quickly or even more quickly than the wall charger. Unfortunately it no longer will hold a charge. The lights still light up as if it's charging when plugged in to power and it appears to charge (4 blue solid lights), but once connected to the phone there is a charge of less than a minute and the power bank dies. If they can make the life of this product longer I would be more than happy to buy it again, but I sure expected more than 7 weeks of use out of it.Update: Amazon made a one time exception and refunded me for this item once I returned it. Personally, I would have preferred to keep the product but have it working as purchased.

Bottom line, it's cute they make the form factor the same as an iphone 6/7. But the iphone is designed to minimize volume and maximize surface area (screen size). The form factor for a battery should be the opposite: Maximize volume, minimize surface area. So with this battery you get something that is not optimized for the purpose. I'd prefer something about the size of a cigarette package in terms of volume to surface-area compromises.

This was my first time purchasing a battery pack like this. I was impressed with the Redshine power bank. It is super slim and light weight. About the size of a regular iPhone and similar weight. It comes in nice packaging, which impressed me. It takes forever to fully charge...5-6 hours. Once fully charged it recharged my Iphone X from 10% to 100% and still had about 1/4 juice left over.If you're looking for something to help keep the phone charged during a busy day I would definitely recommend this. It's so lightweight and slim that you can throw it in a hack, purse or even extra pocket.

Only first couple of charges were fast charge, then after a few the battery pack failed to fast charge my phone. Right now when this battery pack is fully charged, it takes about 4hrs to charge my phone. Dubious of the quality of the battery cells they are using in this power bank. I would return it for a full refund if I could, but the return period window already closed. Never buy it again. Other users who buy this or have already bought this, have you had the same issue as well??

This thin, sleek, silvery-smooth power bank is my new best friend. It's about the size of an iPhone 8, and it does everything I need it to do. To satisfy me, a power bank like this must charge my iPhone X once, because that's precisely the maximum number of times I'll be using up all of its battery power before I can get to an available power outlet (barring some unforeseen disaster). It also needs to be small and light, not taking up much room in my limited carrying space while traveling.This little Redshine power bank shines at all those things. It's light, weighing 135 g (4.8 oz), and it carries enough juice to charge up my iPhone X from 0 to 100% with an extra 8% for good measure. It looks great, too, where it mimics an iPhone's allure to the point of receiving covetous compliments from all who see it. If you want to hide its beauty, it has a cute velour carrying bag that protects it from prying eyes as well as scratches and dents.Although its maker claims it has 8000mAh of charging power, according to my experiments, the math says its effective available milliamp hours is 2,933.28. (I figured that out by using the known milliamp-hour capacity of an iPhone X, 2,716, and my testing showed that it can charge the iPhone 1.08 times, and that's where I arrived at 2,933.28mAh.)But that's a lot of arithmetic. What really matters is, can this little power bucket charge a dead iPhone X to 100% if I'm too far away from a power outlet to plug in? Indeed it can. Even though I'm unusually persnickety, I couldn't find a single thing wrong with it. It passed my rigorous tests with aplomb. Strong buy.

I was so excited to order this only to take it out of the box and find out that it doesn’t work at all. I tried multiple different cables and iPhones. What a waste of time. Why would they send me a broken battery?!! Why not test the product before sending out to the customer?? It’s really frustrating to order an item only to find out it doesn’t work and now I have to make the trip to the UPS store to return it so I can get my money back. Don’t waste your time like I did, order a battery from a different maker that actually works.

stopped working after three weeks of use....past refund date of courseblue lights turn on and then nothing chargesabsolutely uselessdo not buy

As described it's about the same size as an iPhone and smaller than the iPhone+. Its easy to slip into your pocket to carry around. I almost got one full charge for my iPad and it gets about 1.5 charges for my iPhone+ enough to get me around when I can fully charge at home or office. If you're looking for an ultra-slim design this was my choice of many.
