Will this charger automatically adjust the current or will it fry it? I have a phone that requires 1.0A and dont want extra current flowing..

The device being charged regulates the rate at which the battery is charged. So if you have a charger that charges at a low rate, the device being charged is limited to the lower rate of the charger. But if you have 3.1 amps available, some devices can charge very quickly. With modern charging circuits, having more than enough current available is a good thing!

It definitely doesn't. Apparently the best thing that happened to me was to lose the original charger and buy this one! The only quirk about it, though, is the fact that sometimes if you plug it up to a power strip with other things plugged into the power strip, the green light on it will start flashing. It means it's not getting enough wattage, so just plug it up to the wall and you're good! it's an amazing charger, and I use it to quick charge my phone too! Hope this helps!

Yes it will work fine. Giving your phone the correct current it is a smart charger

Look at your original charger. If the output is 1A then use the 1A slot, if the out put is larger than 1A, then used the 2.1A. I heard that Samsung phone require at least 1.2A to overcome the diode for charging. So most likely you need to used the 2.1A slot. But try it, if both works, then it's your pick. Higher Amp give you faster charging.

This is a EU charger. The 1.0A port is for phones and smaller devices. The 2.1A port is for tablets.

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.

The amount of current that flows into your device (phone) varies. Batteries that are nearly depleted will initially charge at a higher rate. Also as a battery gets older it won't charge at the higher rate that a new one will. Just because your charger is capable of supplying 2 amps doesn't mean that it always will. The amp meter is a great tool for finding cables that have broken strands in them and are unable to carry as much current as another one.

They both work , the charging circuit ( smart phone or tablet ) controls how many amps it wishes to draw. The charger does not decide how many amps to push. The only problem you would have is if you plugged in something that drew more than 2.1 amps.

That is difficult to determine. Though a AC charger may state that its output is 1A, for example. This generally means that the charger should meet or exceed the posted output current. So, even chargers of the same model and manufacturer, your charging output will vary. Even so, a charger that can output 1A does not always do so. It depends on the cable and the device also. I have had some chargers which can output 1.5A charge slower than other chargers that ONLY output 1A. So, in short, maximum amperage output does not mean it is the best for charging a specific device.

Shouldn't be a problem with DC current, Better to have a continuos extension without multiple connectors (length not too much of an issue). it's best to check with manufacturer of the charger.

As far as I know the voltage rating is 120v. I do like this unique wall charger and it works well, but I only have one negative comment. The fold out trays on each side are neat but not really functional. If you have your phone in a small Otterbox or something similar, then your phone won't fit. I don't use my trays at all. Good luck!

It's unlikely to harm being below the amps rated, but it may not charge properly or give a false reading of being charged when it is not fully charged, but even this is not for sure. But if the charger sends 2 amps to a device that is only rates for 1 amp, then yes, bye-bye device.

You will have too USB port and it will give one one amp and the second 3.1 be aware from this charger ones you connect your iPhone to it it will charge for little bit thin it goes off by it sell and you have tou switch on every few minut!It's westing money DONT BUY IT!!

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

Most PC's and chargers limit the current to about a 1/2 amp. That's due to the USB 2 spec. There are a few, such as Apple, Kindle, and others, that charge at higher currents. I would have no reservations using this extension at 2.1 A. Go for it.

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

@Eric never mention any 5.1V. To answer your question this charger is stock OEM rated at 1.2 amps the phone itself can also be charged by a 2.0 amp charge it was design for that if you happen to come across a generic charger rated at 2.0 amp.
