approximately how fast does it charge the galaxy s4 from 0 to 100% with phone off?

Never really timed it nor had to do it. Usually I used it for 15 minute charges between vehicle trips

Well the other day my phone (S4) was dead. I put it for charging and drove for about 30 mins from my work to home. By the time I reached home it was about 50-60% charged. I drive an infinity, which has a 12V charging plug. At that rate, am guessing an 45 mins to an hour.

Should take somewhere around a little under 80 minutes on a battery that hasn't been abused too much.

I have no idea as I use it in the car with the phone on and I never start at 0% anyway.

When I use my Samsung charger that came with the phone from 0% to 100% it takes about 2 hours. When I use the Anker car charger it takes about 90 minutes. I think the car charger is faster because it is 2.4 Amps while the Samsung charger is 2.0 Amps.Also, most smartphones nowadays are able to charge 50% in about 30-40 minutes for a quick boost.

Absolutely. In actual fact I'm using it to charge my Samsung S4 while im writing this reply. And on top of that it charges the phone from near dead to 100% in just over 2 hrs! If you ask me that's pretty fast. It comes with 2 USB cables and 4 different adapters for multiple devices. So you can use a computer or pop on a wall adapter to charge the anker battery. FYI it has 2 ports for charging. So the beauty is you can charge 2 devices at once. Only difference is one port is 1amp and the other is a 2amp. I stick with the 2 amp for quicker charge. Love it every time I use it.

It charges in about 2 hours using the 750mA charger that came with my Samsung Galaxy S3 charger. Hope this helps.

Yes, it's a Samsung charger. It will charge the Galaxy S4 even while using GPS.

I've been using mine for more than six months and I've had no problems with it at all. It charges my S4 3 times or so before needing to be recharged.

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.

I don't have an S4, but it will charge an S3 in the sme amount of time as your normal charging through a wall charger. I haven't timed it exactly, but it seems the same if not faster. On one trip, it's charged my phone a couple times and my ipad. All be it, they were low on battery, but not empty. Hope this is helpful.

Not too sure on that (yet). However, after it charged in the charger, I unplugged it and left it for about 8-9 hours and when it was put in my phone it was still at 100%. Hope that helps.

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 a Galaxy S3 and from 10% I had it completely recharged in about an hour.But I did put my phone on airplane mode to charge.

Jordan if you are wondering if this one of those quick chargers you would find out there on Amazon the answer is no. Results can be different at times but on average my charge time is around 45 minutes from a completely dead phone to fully charged while off.

Most definitely! It will charge a Samsung S4 approximately 4 times before requiring a recharge itself.

No idea... it will fully charge a Nexus 5 in about 3 hrs and an s4 in about 4 hrs...

Depends what you're plugging into. If your plugging it into a power source and just using it as a basic extension it should charge at about normal speed.

Hi, using Trent Ultra (with S4) via the 2A usb outlet I think about 2 hours. I have not actually tracked this but charging time is NOTICABLY faster eith the 2A option. 1A outlet yields normal (4-6 hrs) time. Too bad the Samsung battery life sucks (IMHO) so keep the Trent close by. BTW I found on the one time I ran the S4 down to <10% my screen went dark and unusable!!!! Got online with iPad to find a setting has option to keep screen bright even WHEN BATTERY IS LOW. You are helpless with a darked-out screen.
