What's the input and output Amp? I see some case listed as 5V/1A and some listed as 5V/0.5A. Does it take longer for 5V/0.5A to charge the phone?

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.

It charges 5V/1A or 5V/2.1A. It works reasonably well with my ipad 3. Check the output of the OEM charger comes with your ipad air, does it say 5V/1A or 5V/2.1A ?

Less than four hours is my experience. Easily get 6-8 hours of talk time as a result. Output is typical cell phone rated 5.0V=1000mA.

It takes about an hour to fully charge an s107. The chargers output is 5 volts at 0.5amps.

It is not like the 5V stuff supplied with phones and headsets etc. It is 12v output at .75 amp. A 2 amp at 5 volts unit is 10 watts, this .75 amp at 12v is 9 watts, but it IS different. It's a good thing this has a round power connector to the unit and a non-detachable cord to the transformer.

This has two outputs. Ones is marked with an "A" is for Apple devices. the other is marked with "NA" for non Apple devices I/e Samsung, Android or Other. This puts out 2.4 amperes max at 5.2 volts max. if your device falls at or under these amounts, you should be fine.

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.

The picture says, Apple 2.1A and Android 1.5A. The description says otherwise.Apple: iPhone 5, 4S, 4; iPads and iPods (YES, all of them) @2.4 Amp(Please use your own cable)Android Phones: Samsung Galaxy S4 S3 S2, Galaxy Note 2 / Motorola Droid RAZR MAXX / HTC One X V S; All models @2.0 Amp

It only has a 500ma output, and the Moto X probably requires at least 1A of output. I've had the same experience trying to use an original Motorola Droid (not Droid X, but the first Droid) charger with my Galaxy S5.

I bought one and it's a USB 2.0 cable input and a USB 3.0 on the dock. But for some reason charging speed is as fast as plugging in with factory charger. Also it has a removable base on the cradle itself to fit the phone with a slim armor case. Which was a big plus. Overall a great product Imo

Thanks for the input, i bought this couple of months back.Great product but lowest charging amp is 200mah.Was hoping for 50mah.

The amperage for charging would be base on the charger you're connecting the cable to. This just passes the info and power. I have connected to my Samsung Galaxy Note 10.1 and a power bin charger outpotting 2.1 amps. If I use a lower amperage, it'll take longer to fully charge.

Data is fine. For charging, it only delivers 0.5 Amps, so charging will be much slower than with the 2 Amp cable supplied with the phone.

Specs: -Add 500~600% to smartphones, 300~400% to large screen phones, 100%~130% to tablets -Input: 5V / 2.1A (max) -Output: 5V/1A + 5V/2.1A -Size: 3.6 x 3.4 x 0.9 inch; Weight: 8 ounce -Recharge time: 8-10h via 1A USB wall charger (AC charger not included) This should be the correct size.

This won't even charge modern cellphones as fast as most car-chargers (or that type of USB output that you plug into the cigarette lighter) can do. RE: John Taylor's misleading answer.2.1amp standard for USB3.0 and newer USB2.0 * 5volt standard USB socket = 10.5 wattsThis product's 0.5 amp * 12v = 6wattsUSB3.1 in 2015-16 = 100 watts!!!!! Try to wait for charging products that accomodate USB3.1 if you can; it's a HUGE jump in wattage & e.g. my Galaxy Note2 (USB2.0) take 8+ hours to recharge; also expected in 2015-16 are 1080p 3D head-mounted micro-LED displays worn like sunglasses for <$500 (mass-consumer price range) that draw ANOTHER 7watts or so.

I do not know exactly what you mean with output. If you are talking about the voltage it yields, I have no idea. If you are talking about the voltage of the outlet where the charger can be plugged in, I will say 120V. This charger works really well, and the cable is long. If you have a blackberry, it will perform wonderfully, and it also works with Samsung, LG, Motorola, and Nexus.

On the phone or old battery there should be a voltage and milli-amp rating, ideally you get the same, never less on amps. Physical size and connector is next check, make sure red and black are on same side, I have only seen two styles of connectors through the years. Last make sure you give new battery the twelve or eighteen hour initial charge as recommended. Happy hunting.
