Does it only have one port capable of charging at 2.5A? I have 2 galaxy devices and would need to charge them at the same time.

MANUFACTURER RESPONSE: Thanks for asking! 2.5A is the total power available from the power supply- NOT the amount of power available to ANY ports. To say that another way, you would have 625mA (.625A) power per port max when using all 4 ports. The max current draw for a device complying with the BC 1.1 specification from any given port is 1500mA (1.5A). Please note this full current draw would be available to only one device at a time. When charging 2 devices simultaneously, we would expect charging at a max rate of around ~1250mA (~1.25A)- assuming no current is required by devices in the other two ports. Sorry we can't offer a more clear explanation here- USB charging is really a complex topic where devices from different manufacturers have very different behaviors. To top that off, many devices actually negotiate with the host PC to determine what rate to charge at, so behaviors on these will vary depending on whether a host PC is on and awake versus when there is no host PC or when the PC is sleeping.

I tried charging two at once and it didn't work. I think what was really intended is the one mini/micro whatever it is connection on the face is the only charging connection... On the positives, its a neat little device and I do mean little, the power adapter is much bigger than the hub.. I would still recommend buying it just based off its overall size and portability, I just kind of like the thing... Sorry no I dont think its capable of charging two devices at once.

Hi, I just tried charging two Galaxy S4 phones with this device. They are displaying a charging status. What I don't know for sure is what charge current they're drawing. If there's a way to get the phone to tell me that, let me know and I'll check (yeah I could cut the cable and put an ammeter on it, but I'm not quite that curious...).

It has multiple USB port along with one mini USB port. Multiple USB port can be charged/powered at the same time.

I use this purely as a charger not as a USB hub. The key is being BC 1.1 compliant. I charge an iPad and iPad mini at the same time. It can pump 2.5 amps max across all ports. It will charge all 4 devices at normal USB rates but if you only hook up 2 devices they should both charge twice as fast! (1000 mA rate)

Not one port charges my iPad. I believe the 2.5A is the power into the Hub and it distributes that power to each port.

They both are connected to the same circuit inside, and it is the total current of 3.1A that matters. So any one of the port you can use for charging a tablet (and it will take 2.1A current from that port), and the other port can be used to charge a smartphone (which will take 1A current from that port). Thanks!

Hello Tim. The USB ports can be used for charging one 2.1Amps device or two 1Amp devices.

It's an 8amp charger, 4x 2amp ports. It charges Samsung phones and tablets just fine, also iPhones. I did not try iPads yet. They are listed with 2.1amp

I've used both ports for my galaxy S2 and also used one for my phone and another for my nexus 7 at the same time. Just use the 2A port for whichever device requires more power or in the absence of such a distinction, whichever device you wish to charge faster.

The first one you use Will always charge at the full 2A rate. If while one item is charging you charge another item, that port will always charge at the lower rate.

Features & details4 ports (5V / 7.2A total) power maximum-speed charges to 2 Apple (2.1A max) and 2 Android (1.5A max) devices - simultaneously.

In theory it should be able to supply 500mA to any given port, of course with a power supply of only 1000mA it will not do so to all ports. I have been able to charge both phones and tablets without any problem, however I have not tried more than two at a time.

No, there are no problems if you charge cell phones on a 2.1Amp port, The rating shown here is a limit. so let's say your phone only allows charging at 0.7 amps, You can put it in any of the 4 ports.But let's say you have a tablet that can take up to 1.8 amps you can put it in the 1 amp port but it will just take longer to charge unless you are using it at the same time where it may not actually charge it would just keep you at the same level while you were using it.

I use the 2.1A port to charge my Samsung Galaxy S4 and it works well. I know this doesn't answer your question about the S5 (sorry), but it may help S4 owners.

The specs provide the information you are asking. It provides 2.1A per port simultaneously which is enough to charge two ipads at the same time as quickly as if you were using two individual ipad chargers. In practice, it seems to work as advertised although I don't have any way of measuring the output while both units are charging.

Hello, yes you can charge 2 devices simultaneously. If you only use the blue 2.1A output, then the output current is 2.1A; and if you only use the 1A output, then the output current is 1A; if you charge 2 devices simultaneously, the total output is 2.1A.

1A port can charge a smartphone; another port (2.1A), is for larger devices, such as the Apple iPad and other tablets. Currently there are smartphones that accept the 2.1A input as well.

Yes. It has dual charging USB ports so that you can charge two devices at once.

There's a 2amp port for tablets so you can use charge and use your device at the same time.

I have had my phone (Droid RazrM) and my tablet (Galaxy Tab 2 7") charging at the same time. The tablet uses the 2.1 volt port. Not sure if they got the same charge rate as they would have one at a time, but they both showed as "charging" while plugged in.

Yes, you shouldn't have any problems charging any of those with the 2.1 amp port. You need to use the 2.1 amp port to charge tablets or else it will take a looong time to charge.
