Does it provide high power (2A or is it low power, I want to power a LG G3 or Galaxy S5)

I use mine with my nexus 7 2014 version that uses a 1.7a charger and don't notice a power drain while in use.

I used this with a Galaxy S2 and it worked ok. It is a bit on the slow side. I currently have a LG G2 and it seems to work ok with that, but still a bit on the slow side since it is only 700mAh. It is good on a long trip, but would not recommend it if you are looking for a quick charge.

Yes this is the best Power Supply I ever had..Has the 2 6plus and the 2 optional. Nice and quiet too. Buy this and you won't regret it.

Your Samsung Galaxy S5 should charge fine on the 2.1A port, as well as a 1A port. My iPhone 4 charges and works well with either. The voltage is the same. The difference is the amount of power (amperage) available to power devices. Here's a very well written article on USB charging ports for those who want to know more: http://www.extremetech.com/computing/115251-how-usb-charging-works-or-how-to-avoid-blowing-up-your-smartphone

I have one and it works great. Lots of power. I keep it charged all the time so it is ready to use at a moments notice. Your phone is the same as mine so no problems.

On my LG G2 with a 3000mAh battery, it will fully charge 1 and a half times. I forgot to fully plug in my phone one night and it was totally dead. I fully charged it, ran it for a full day (very bad reception in my building which drains the battery faster than normal use) and charged on the way home . On the second charge, the phone went from 40% to 95% before I unplugged it. The Anker was not fully discharged but only had one light left on it's indicator...if this helps at all.

Depends on your phone, your usage, and distance from cell tower.It recharged my Galaxy S3 from 20% to full, my Galaxy Tab Pro 8.4 from 65% to full, and a friend's Galaxy S4 from 15% to 45% and still showed 2 out of 4 LEDs worth of remaining power. This was over a two-day period. I would GUESS that I could get maybe (or almost) 3 charges (from 20%) on my Galaxy S3, but I wouldn't count on 5.I'd recommend adding a car charger and/or solar solution to this battery if you're shooting for five days.

Not sure if it works with your specific phone, works with my LG G3, but it does need A.c. power.

Most likely check you wall charger if its under 2.4A or 2400Milliamps output no problem. If its over that rating it might just charge a little slower in your car.I have not found any of my power hog devices that I can't charge. USB2 is rated at 500 MA and USB3 is 900MA so this charger output is well beyond USB3. Not much using this power level and the devices I have charge very well. I charge a Samsung Galaxy 10.1 note and it has no issue even when playing games during the charging.

I believe the newer phones may require more power, you may need to unplug some other devices that are also drawing power. Also, plugging in the adapter and into a computer will give you added power.

It is powered by the USB port. In fact, actual USB 3 ports have stronger power than USB 2.

I don't know the power as I haven't a means to test it, but I'd assume that 500mA is what they provide. I do know that they provide power and I use thme to charge usb speakers, a small helicopter, usb headset and many other devices as well as a Nook HD+ and IPad all at the same time. I also use it as a hub when I'm on my desktop computer (usually on the laptop).

I've had my particular charger charging both my Samsung Galaxy S3 and my friends Samsung Galaxy Nexus. It doesn't seem to "care" that one port is higher rated but you will notice the 2A port charging nearly twice as fast.

I bought the Galaxy GT 430 because it works with a 300 W power supply. Check the specs for the power requirements for the Evga and make sure your system supports it.

The device operates on AA battery power but is supposed to draw power from a USB port that connects it to the PC. If an AC adapter is needed, I would look for a 3V universal adapter at Home Depot, Radio Shack, or Frye Electronics: take the unit in with you but save time by calling them over the phone ahead of going there..

I have to disagree with the posts here. Yes, you can but only under certain conditions. If you are hooked into your computer USB port to charge the battery pack, then no, it won't. However, if you are plugged into a higher amperage charger ( I use my 2.1 amp Samsung tablet charger) then yes, it will power both ports and charge. I have run my tablet and my Galaxy 3 phone off of it while having the battery pack plugged into my tablet charger and it worked just fine. Started at 43% charge on the battery pack, charged both the tablet and phone to 100% and unplugged at 63%. I'm sure it would have continued to go up if I had left it on but I was at work and had to move to another department.

I have one of these and charge Samsung and iPhone's on it (and up to 4 devices simultaneously). However, there are no AMP markings over the ports and the "owners manual" that came with it does not specify. With a supplemental power supply, you shouldn't have any issue charging, but it may not be "rapid charging".
