Can you charge *any* (e.g. 1amp) device in *any* port (e.g. 2.1amp) and be assured that it won't be harmed by over-amps being supplied

I've charged 1amp devices in the 2.1amp outlets with no problems. I have. Blackberry which will not charge off the 2.1amp outlets for some reason but no damage has been done to the device

'Over-amping' a device is impossible by the laws of physics. So no worries there. The amperage listed per port is the maximum that port is capable of supplying. A device will attempt to consume the amps it was designed to up to the limits of the port it is plugged into. More amps means faster charging.This is all before Apple enters the picture because they do strange things to try and force their customers to buy only their products. So a 2A 'apple' port may not supply the full 2A to non-apple devices and vice versa. Unless Apple got their act together which I doubt...

I use 2.1 to my Htc one m7 and i dont have problems. . I usually use 2.1 because my others chargers are for iPad (first Gen)

All of the ports are labeled with what they take from android to apple. Then on the side it tells you the amperage. There are 2 - 1 amp ports

I just received this and it has changed from the description and picture. All of the ports are now referred to as "intelligent ports" and none are labeled with any particular device. The instructions say it will adjust to the device and deliver appropriately for a full charge.

I ordered this device and all of the ports are intelligent, no need to plug into a specific port. Great improvement but the description has not changed.

As far as I can tell, you can charge anything that uses a USB charger. I have charges an iPad on it with no problem.

I wouldn't risk it... in my experiences, plugging a charger with stronger wattage into something can cause rather unfortunate problems

Yes it is perfectly safe to use the adapter as you are using only 2.7 amps. I would groung the plug to be safe but everything would be ok.

You can do it without a problem . I used it to charge my laptop with 90W rating.

You don't have to, your device will only pull as much current as it can handle. The 1300mA is an upper limit, not a fixed value.

2.1 amps shared; it can produce the full 2.1 amps only if 1 port is being used. 1 amp per USB port can be used if both ports are in use.

Yes you can .You can charge anything useig 5volt .That's mean all phones and most of the tablets .

If a device requires 2 amps to charge, but you only supply 1 amp, it will not charge, and it, the device will strain the charger, possibly damaging it. This is dependent on the battery type, charging circuit etc.It's best to have more available current than needed.

Shouldn't hurt at all. Computer will only draw what it needs. It won't fry any more than plugging that 90w charger into a wall outlet that has about 1800 watts or more potential in it. (120V X 15A)

Yes, I believe that should pose no problem. The resistance of a longer wire would just slow down the charging rate slightly, 1 amp is a good charging rate. -a rocket scientist

Not really. It only charge USB devices iPad, phones etc. Computer needs much higher voltage.

I'm sure you can. I use it for all sorts of different devices. I have noticed that it may take longer to charge certain items than their own plugs may but I haven't found anything that didn't charge at all.

No, I would not. It does not seem to be strong enough to charge more demanding devices.

Well, all I can say is that I use it with an Anker battery pack, which says 1.5A input current. As far as I know these new chargers, which output via a USB connector, establish sort of connection with a device being charged. And the device itself will only take whatever it is capable of. So it's not like the charger will shove those 2Amps down the device's USB connector. Your device is supposed to support whatever current is listed on the device. Otherwise it will just use as much as it is capable of. That's what I've been told. Hope this helps.

That's what I'm using one of them for. Works well, but make sure you get yourself a 2.1amp charger. You'll thank me later.

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.
