It works as a charger but the color changing part of it is already starting to malfunction worth the price compared to what you pay at a store

It is billed as a keyboard that can change colors but if it is possible to get the lights to do anything other than breath then I can not figure out how. Other than that it is a great keyboard.

First off, Anker service is top notch.  Have issue with it not always fast charging Google Pixel and they ship me a new one right away.

Unfortunately the new one has the same issue.  After the 2nd charger, didn't bother to ask for more since this is likely a design problem.  At least it works as a charger.
 Not "charging rapidly" or "charging slowly" - just "charging" - unlike my wall USB-C charger or even my 2A USB-A-to-C that shows charging rapidly.

As a 4 port car charger with 1 USB-C, it is good.  If you want to use the USB-C one thinking it will fast charge, then it may not work for your phone.

Bought this cable to use as a secondary charging cable for my iPad 2.

Color is definitely not as bright as pictured. More of a peach color than a true orange.

Shipping did take a very long time (about a month), but they were honest about that with the delivery estimate given at time of purchase.

The cable works okay. It doesn't tangle like traditional charging cables, but the flat cable isn't much easier to use. It has limited range of motion, meaning that while plugged in to charge it can only move up and down, not side to side like traditional round cables. It definitely doesn't charge as fast as the original iPad cable (which is to be expected with most after market/non-Apple iPad products).

The part that connects to the iPad is rather short and (because it doesn't require you to push the sides in to release from the iPad) it can sometimes come out pretty easily. I fine myself checking pretty often to make sure that it's still plugged in and charging.

The color and style make it stand out from other people's charging cables, which prevents mix-ups. If you're looking for a pop of color to stand out from the everyday, this is for you. If you're looking for great performance and speed, I'd look elsewhere.

The color does not at all match the gold Samsung color. It looks like it does on the pictures but does not match at all. It charges good but wish it would charge better, when the charger is low it won't charge your phone. Over all it is worth the price and good to have but just make sure it is fully charged so it can bail you out of a situation where you are not able to charge phone any other way.

Works as advertise. Still need to see what color shifts it has.

Batteries work fine but there is no color change in the light that I can perceive when the batteries are charged. I bought another wall charger that changes from pink to blue when charged. Will only use this when I need to charge another battery at the same time.

This charger works great for charging my Lumia Icon, but the super-bright LED indicator lights up the entire room at night. It's like a mini-flashlight. You can use it for a night light. Don't put this on your bedroom. I like the price though.

It works fine.  The problem is the blue light that turns on when plugged in is very annoying at night.  It is so bright, it could be used as a night light.

It works, I just think it's an ugly color of light. I tend to turn it off and use a warmer lamp.

It works ok to keep my phone powered up while it's plugged in but it doesn't charge the phone.  I have not tried data transfer so I don't know how that would work.  I bought this as a charger and it's just not doing the job.  Reading the description, it doesn't say very much about charging so maybe I bought the wrong item.  It fits my Galaxy S5 perfectly and the cord doesn't tangle and the color makes it easy to identify.  My phone gives me a message when this cord is plugged in that for "faster charging" I should the cord that came with my phone.  I just wanted a cord to travel with so I could leave the original cord at home but it doesn't do that.  If I plug this cord in while my phone is at ~15% battery I maintain ~15% battery whether I use the phone or not but it doesn't ever increase the charge.

it works, however after I charged mine, the blue charging light stayed on, dimmer than when charging, but it stayed on while off, and disconnected slowly milking the battery.

It worked fine the first two weeks or so. But now it won't charge full and the lights glitch up so its not working properly now.

Only have this for about 6 months. Lights have stopped working for a while now. Charger seems like it is still working. Not sure how fast and well it charges via solar, but it does work and have used it to re-charge my phone a couple of times.

It work perfectly but should work on making paint match the actual color of the phone when you put it on you can notice that they do not match color

The color changes all of a sudden to greenish or orange. Sometimes only 10% of the picture is seen.

Also Samsung Hub is not that good. Inbuilt browser hangs many times.
