As I wold only need this for charging cell phones, would there be problems if the cell phones were charged on the 2.1A port vs. the 1A port?

I would not foresee any problem with that. I've charged my cellphone on several of the ports.

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.

Assuming this device is a relabeled Anker 25 W five port USB charger which is the device I purchased (it appears to be identical), then there will be no problem charging phones with a port that can support tablet charging. However a tablet will charge more slowly if plugged into a phone port. I don't know if I can post links here but the Anker site has a manual that describes this feature. http://www.ianker.com/support-c7-g262.html

Im sorry but I dont know what 2.1 A or 1A port is,lol I can say this. We have Iphones and it charges those.It also charges my gf I pad and the kindle fires the kids have and my e pad. It does not charge my Play station 3 controllers. I ended up buying another one after my 1st purchase so we now have two.One for the bedroom and one for the family room.I think its a great item to charge multiple things with one plug in instead of having outlets through out the house charging phones ect.

Two devices can be plugged in at once. One in the 1A port (like a phone, camera, etc) and one in the 2A port (like a tablet, or other device). Tablets will not charge off of the 1A port, but phones and other low-draw devices can charge off of both ports.

I do not own any I products, but the answer should be yes. Since this is dual voltage, If the 2.1A port will not work for the Iphone then you can use the 1A port instead. I have used both ports on all my android devices and have not had any issues with either port.

No - I have not see any issues plugging in 0.5A devices (BT headsets) in a 2A port on this charger on both the device and charger. I have noticed the charger gets hot when I plug 3+ devices onto the charger but not unusual compared to other charging bricks.

Both should require the same 5v for charging. This charger has a 1 Amp and a 2.1 Amp output. The 2.1 Amp is stronger, but software on the tablet and phone should be able to adjust as needed. The issue is typically whether a third party charger has enough amperage for what the individual device expects. 1A and 2.1A should be more than enough. Plus this charger is sleek, sexy and solidly designed.

I use it to charge my iphone from the 1.0A port all the time and it works fine, but it probably wouldn't work as well with the 2.1A port since charging input is only 1.0A

I use both ports for phones including my Samsung galaxy phones with no problems although they do charge a bit faster on the 2.4A port

Hi Alex, I have used a 1A, 2A charger & my laptop USB port. They all worked perfectly, charging at different speeds, of course.

You only want to use the correct amperage for your device. I believe that this device requires the 2.1A charger.

I'm not a genius, but it appears to function the way you describe. The instructions indicate that the "A" port (I assume the "A" stands for Apple) will put out the 2.4 A when used as a single port. The second port, labeled "NA" is for non-Apple devices, although I charge my iPhone with it. The catch is when you plug in two devices, the overall output is still 2.4A, but it is distributed to both ports.Hope that helps!

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".

This device will not charge two tablets (2.1a) at the same time. It will charge a phone and a tablet or two phones at the same time.

The 2.1 is a faster charging port for newer devices, but you can really use either one.

Hi Terrence, The 1A is used for charging most smartphones and small devices. The 2.1A is used to charge bigger devices such as IPAD and other tablets more efficiently as they have a bigger battery. Having said that, the 2.1A is not limited to charging tablets, you can use it to charge a smartphone too and it will work just fine. Thanks, Omi Labs Store

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.

All you need would be a usb cable that's a 3.0 and being that it has a 2A port it will charge your phone

Yes one of the ports is 2.1 amps and will be able to. I have an LG G2 and it charges great
