Does it charge Android phones at the 2.1 Amp rate?

It may depend on the phone. But I have a Galaxy S4 and it charges very quickly. But my friend has a older HTC and it does not charge at the 2.1 AMP rate. hope this helps.

I have the Galaxy S4 and it throttles down to 1200 if the screen is on and 1900 if the screen is off. You have to have the right cord though. If you are using a non-shielded cord, it will throttle both of those numbers down. But, this charger will put the max current into your phone that your phone will take. Just use the right cord.

What tcash1991 said. Some phones, like my previous HTC Thunderbolt, have a rate threshold of 1 amp when pairing with chargers. When connected to a higher amperage charger they either charge at a very low rate, or not charge at all.

It does NOT charge Samsung Galaxy Nexus (factory firmware) at 2.1 AMP rate. The phone decides to use USB charge mode at 0.5 AMP and gets hot and shuts off charging some time later.For those picky phones, I recommend ANKER Car Charger with Micro USB AND USB port dual charge.Charges perfectly on HTC MyTouch 4G with CyanogenMod firmware. (Didn't get to try OE firmware)

I think this was 5V/1A output. Its a little slower than plugging it into Wall. Yes it will take longer for phone to charge on 0.5A than a 1A. There are a few chargers like Alpatronix which have 2.1A output as well.

The current output for this charger is up to 2.1A. So it can charge any smartphone, as well as any tablet that uses a micro port for charging - CRAZYONDIGITAL

As others have stated you can't exceed 2.2 to 2.4 on a given port, but that wouldn't matter, because it isn't the charger that decides the amps to charge at it is the device. The only thing the cable and chargers do is supply enough amps and low power loss. An average device won't pull above 2 amps regardless of the output of the charger. The S4 pulls 1.8amps at its full draw and its oem cable and charger are rated for 2.1 if i remember correctly.

The charging time will not be affected, however realize that the charging rate of the 1 amp is slower than the 2.1 amp.

Should be rated at 2.1 amp. Charges as fast as my Belkin charger rated at 2.1

Hard to say for sure, but the charger/adapter output is less than 1 amp. (975 ma) combined for both supply voltages.

Yes, the specified output is up to 1 Amp. Most smartphones can be easily charged with this type of device.

Don't know for 100% sure, I haven't tried, but I'm 99% sure it will. It charges an iPad mini and my Droid with no problem. It has a 2.1A and a 1.0A outlet, the 2.1A has no problem with any device I've used so far.

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.

Actually there are such things as dc-dc converters in devices.I have 5v mini/micro usb portable charger that uses a single 1.5v battery.So it can be done.I've also read that the xoom has a menu setting that allows charging via the usb lead.Also Mr Partridge needs to learn that mA means milli-amps. So usb 2 can deliver 0.5A or 500mA.Most phones try to suck out 0.8A (800mA) yes, that is why some USB ports can't charge a device as the phone makers are breaking the usb2 spec. USB3 now has a limit of 0.9A thankfully.

The charging capacity is 2.1AMP, most phones & tablets will charge at the rate, which is limited to the device's capability. Therefore, if a specific android phone limits the charge to 500 ma, if will only charge at 500ma.

Yes, it should fully charge the Note 2 from 0-100% with additional charge to spare. ~1.5+ charges

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.

I've had my particular charger charging both my Samsung Galaxy S3 and my friends Samsung Galaxy Nexus. It doesn't seem to "care" that one port is higher rated but you will notice the 2A port charging nearly twice as fast.

No - its a simple wall charger with the amps you need to charge larger devices.

Theres a 1A and 2.1A usb on the side, I use the 2.1 and find that my droid charges up pretty fast
