How long does it take to charge a Galaxy S4 with this device?

I'm not sure I used it with my iPhone when our power was out and it wasn't fully charged either. It basically maintained my power while I made calls. I've used it multiple times like this. To maintain my power.

I have galaxy s4 mini and it took about four hours to charge a battery but here is the real deal I got two of them and both broke within a week of use. Not worth the money for the effort Needed to replace it and make it work.

I would say this link could shed some light on your issue. http://lmgtfy.com/?q=s4+maximum+charging+current

Yes it will, charge is not that quick as when you have it connected to the outlet but yes this will charge your Galaxy S4.

The coil says 500ma on it, so it most likely only does show charging. On my S4 mini it said "USB" on the charging screen, which is slow charging.

Im unsure specifically for the S4. But for the S3, and using the 18 000mAh battery, it could charge that phone about 8 times.

It doesn't take long... just about as much time as your cell... It is best to turn off any device while charging for faster time. I plug my unit in at night and charge while I'm sleep... since I only use in the mornings! Very neat with great sound... more than you really need in an average crowd.

I have an iphone 4s and it completely charges in about 2 hours. However, you can use the phone while it is charging.

Not sure about the s4 but the device can also charge the blackberry? Hope that helps.

Hey if you're using the 2.4 amp super charging side on the top front, I'd estimate about 2 hours. It takes less time to fully charge my Samsung Galaxy Note Edge. I can get a full charge in under 2 hours.

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

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.

I bought this charger specifically for the Galaxy S4 and it works great. No problems.

Typical time it takes to charge your phone roughly four hours but there are indicators on the front of the charger. They blink whilst it charges and they stay lit up once it's completely charged.

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.

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

If you have the regular USB cable then yes, it may take a bit... depends if you are placing the charger in full sun... then it's a breeze. Regular IPhone4s in about 30 min.
