GreenTekMobile Premium Qualcomm Quick Charge 3.0 Bundle: 10000mAh QC Aluminum Exterior Power Bank with Type-C + QC Wall & Car Chargers + QC Cables + Type-C Converters: LightningPoweraid (Silver)

Thus far, and I haven't had to use it a lot, it has mostly done its job. I'm using this with a Galaxy S8. It's nice to know that I have emergency power in case I'm not near an outlet for very long periods at a time. Frankly, the S8 currently (no pun intended) does a good job of holding its charge, but we'll see what happens after a while. I bought this because of the added feature of being able to charge and/or use the phone while the Quick Charger unit is also charging.In any case, the one small blip with this is that I tried charging my S8 from about 30%. I got a fairly quick charge, but the unit stopped charging when it reached 99%. Using a cord straight from the wall, my phone regularly charges to 100%. Any reason it would stop at 99%?

I have been using this for about a week and am happy to say that this is one of the nicest batteries I have ever owned.The packaging itself is really sleek and well protected, coming with all the advertised parts neatly wrapped and securely fit. Everything in the kit just feels nice - the wall charger, adapters, cables, and the car charger all feel robust and fall into that nice, clean aesthetic. To my surprise, even the travel pouch felt high quality and housed the battery perfectly.As for the battery, its design already makes it nicer than anything else I've ever owned. First off, it basically looks like an IPhone. For reference, the battery's length/width runs less than my IPhone 7+ while slightly thicker and slightly heavier - pretty incredible. It's easy to use - press the power button once to turn on, press twice to turn off. There is a simple LED light display on the side which indicates the battery power level, and once fully charged it will shut off automatically.The best thing about this battery though is that it charges FAST. There are three ports on the battery, 1 micro USB, 1 USB Type-C, and 1 USB A port (traditional USB.) I believe the micro USB and USB A support Quick Charge 3.0. I tested the Quick Charge 3.0 USB port with my Plus and it went from 35% to 80% in a little under 40 minutes. I would like to try this with my dad's Galaxy S6 just to see how it compares as I'm sure the charge time will vary between devices. I was only able to test the car charger for a short amount of time, but it went went from 45% to 58% in around 15 minutes. The car charger supports QC 3.0 as well so definitely excited to be able to try that for an extended amount of time in the future. Haven't been able to fully charge the battery itself yet, but the product description says 3 hours to a full charge which is pretty quick as well.For how quickly it charges and the number of accessories you get with the entire kit, this is a solid buy. It looks good, charges fast, and is versatile. Considering the wall charger brick, cables, and adapters run you a few dollars each, the value is really there. I was looking to buy a battery for the longest time and am so glad I got this one. Will definitely be recommending to my friends.

the price of course it was got me! I was in need of a type c charger and quick charge wall charger! so when I saw everything that this came with for the price I was very skeptical, especially since its been on sale for over a year and only has 20 something reviews. well I should have gone with my gut instinct and got something else because I've only had this for 4 days and the type c to type c doesn't work anymore..I guess it was too much wear and tear for 4 days because the wires are coming out where it bends..I hope I don't get charged for shipping trying to return this..ill do an update if I do! but other then that is been charging my phone..I have another power bank that has 10,000mah and it lasts longer than this one does..this one is also very heavy..

This Greentekmobile powerbank does what it says it does: charge phone batteries real quick and no buts about it.Being an engineer, the form, fit and function matters to me. I have used it for two weeks plus, and like it very much.The charge time for this for my Samsung Note 4s were about 1%/min. This, by the way, is what you get with thewall plugged quick charger.Cost effectiveness is the word that I use for this product package. It came with everything I need to use it withouthaving to buy any accessories for a charger. The box it came with had cut outs for each device for storage.This is good as I have lots of devices scattered on my desk.This battery also has that hefty feel about it. The weight of it makes it feel like it is built solid, not too heavy, nor too light.Its slim design fits perfectly with my Note4 phones to carry around for whole day for office meetings.The kick I get is that I don't have to find a seat next to wall plug anymore. This is a big plus if you need your space.I am sure you will find this device very useful. I am very happy with this power bank package.
