Anybody use the 3000mAh version of this for charging a Samsung Galaxy S4? If so, can it charge S4 at least once completely and how fast?

Yes I bought this for my s4. It can charge it from 10-100% and still have 25% charging power left. It definitely does not charge as fast as your wall charger but it will do the job. I highly recommend this product! Easily stored in a backpack or bag. 8 out of 10

That is around how many hours it takes to charge mine when using their charger. It is done by the time the second battery is drained low from normal use, and then I just swap them out. If you charge one in your s4 cell phone using your OEM charger that the Samsung S4 came with, then it is much quicker.

The most I've tried to charge my S4 on a full charge of the NewTrent is six times. It takes about 90 mins. to charge.

I have the Galaxy Note 2, though the Sprint version. I've used mine multiple times to charge my device--but only for a couple of hours here or there. (I've never left it charging for hours to see if I could achieve a full charge.) It works great! It's 3000mAh, so it will charge my 1900mAh battery, no worries. Hope this helps! =UPDATE= Upon double-checking, I find my Samsung battery is 3100mAh, so I'm sure a full charge cannot be achieved. That being said, it does work great for bridging the gap between a low battery and the time you can get back to a wall charger.

It takes 2 hrs 45 mins to fully charge my S3 (0% to 100%) with a 3 ft cable. If you use a longer cable, it might take longer. In general, device will pull power at a rate of what it is capable of. Higher amp will not necessary charge your device faster. I believe S series cell phone only requires less than 1 amp for charging. This charger will be more than enough for your cell phone. This charger is good for device that requires 2 amp+ of power source. Also be aware of specs of the charger. A lot of dual port charger claims to support 2+ amp. However, the total is split between the 2 ports (ie each port can only supply 1 amp power source). One more thing, Apple charger (even though it supports 2.1 amp) will not work with Android devices. It will work. However, it will be painfully slow. You might get 1% per hour. Hope this helps.

It should have no problem charging the S4. It is strong enough to power and charge many cell phones and tablets.

Well, I have an S4 and compared to the charger that came with it, no it does not charge "quickly". It takes a very long time to charge without using the phone, and if you're using the phone with it plugged in it will actually continue to drain or stay where it's at depending on the brightness.

I tried it with a coworkers S3 and it did not work. The S3 does not have a Qi chargeable battery so it will not charge on its own. I think you would need to use a third party battery if you want to be able to use it. I think they added Qi to the S4 though I have not looked into it.

Yes, this cable will charge a Samsung Galaxy S4. It will, however, charge slightly slower than a plain cable as some of the power is going to the glowy bits & their controller circuitry. I've had mine several months, use it regularly, and have experienced no problems. I find it particularly useful in the car at night where the cable can be hard to find.

I have charged my Galaxy S4 on both. It charged quicker on the 5V2A slot it seems.

You just plug it in with the provided charger. It's not a USB or micro USB. They send you a propriety charger with it. It charges fairly fast too. I use this power pack to get extra juice for my note 3 phone (huge 3200 mAh battery) and my note 8.0 tablet (also huge battery). It works like a charm for both. When I had the galaxy S4, I was able to get 3+ charges out of the power pack.

I owned the Motorola atrix and it would charge that well past 75% before dying. I now own the Samsung galaxy s3 and I get a little over 60% when charging the phone from 1%. The device is great when you don't have an outlet nearby and just need to buy time until you can sit you phone down for a period of time and charge it...but to directly answer your question if you charge the portable power pack fully it stays fully charged until you use it to charge another device. I've let it sit for weeks after a full charge, powered it on and it was still fully charged

It charges my Samsung Galaxy S4 almost 3 times when fully charged. Hope that helps.

Indeed. I'm in fact responding to you right now on my S4 while it and my ipad are charging. I was concerned when I received it because the packaging alluded that multiple requiring 1A could be charged at once but only one if the unit requires 2A (like an ipad). I can confirm however that I can charge my S4 and ipad at the same time. It may take longer, I'm not sure. But if I plug both in when going to bed, both are charged when I wake in the morning.

I have an S4 (Verizon, but that shouldn't make a difference) and it works great. Though a little more flimsy than the more expensive ones, I found it charges just as well if not better than more pricey models. I got the receiver here Expower(R) Qi Wireless Charging Receiver Card Coil for Samsung Galaxy Note 4 IVA word of advice, don't get the Anker charger. They sent me 2 and neither worked with the S4

I let mine sit for ten days unplugged and when I went to use it it showed full charge still and it charged my galaxy S4 twice to full and still had at least 50% left. I like it. Even though it has 4 ports the strongest output is 5v. At 2mah which is what my phone takes. Dont know about multiple charging. But fantastic as long term stored power for your cell

I have the Samsung Galaxy S4 with the Samsung wireless charging case (QI compatible) and it works great! It charges at 620 milliamps, which is a little faster than over usb charging on a computer and slower than plugging in the cable to the wall directly. I bought 2 - one for overnight charging and one for charging at work in the afternoon. There is only a dim blue light when you start charging, no beeps or noise.
