I have a Nexus 7 tablet and a Samsung Galaxy S3. If I were to charge both at same time, what would each device receive in Amp and watts.

I'm not exactly certain, but I charge my iPad 4 and iPhone 5 along with my jambox speaker and jay bird wireless earbuds all together and it works perfectly

I think it should be fine, I charge iPad along with my kindle fire and my iPhone. They seem get charged pretty fast. But I noticed that when I use iPad or kindle fire while charging, it barely keeps up with the battery depletion level.

I don't have an iPad 3, but I don't think you would be able to charge both, simultaneously, from the USB ports. They're standard 1500ma ports and iPad 3 requires a 2100ma port to work. You could use an iPad brick and a USB port to charge both.

I know what you want to know, but your question has a slight error. You want to know how many mA (milli-Amps) this device puts out- not how many mAh (milli-Amp-hours). From the product description: Dual USB Charging Ports: Provides 1.0 amp of current when charging one device, and 0.5 amps of current to each port when charging two devices from AC or DC power. For AA or 9V charging, single port charging is supported. DC 5V +/- 5% 1000mA MAX So if your device is capable of absorbing 1000 mA (1 A), and you leave it connected for 1 hour, you would deliver 1000 mAh. Two hours, 2000 mAh, three hours, 3000 mAh, and so on. It's perhaps a fine distinction but it is important. HOWEVER- I think you may be disappointed if you try to use this as your primary charger for a device that requires 2100 mA of charging current (note I did not include the 'h'). It will only deliver 1A maximum, so if your Galaxy Tab will even charge from this device, it will take approximately twice as long as it would to charge from the Galaxy Tab's original AC adapter. HTH

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.

We do run a phone and a tablet on this at the same time with no problems charging both, as long as one uses a USB, I've never tried charging two devices that both use the dongles, but it should work. It will also charge two USB devices at the same time.

This should charge just about any tablet or cell phone. Just as a note however, these devices are widely known for not "fully charging"-- unless you get into the more expensive ($30-$50) lines. It's just the nature of the beast; there's only so much charge one of these can push. But it's typical to get a 75% to 95% charge from these devices-- which is quite sufficient for most items. The mAh rating and the total amps are the keys. This device has a 2 amp power rating; some have only 1 amp. Total charge on this is 5000mAh; most cell phones have between 1800 and 2800 mAh batteries, so that gives you some idea of the charging capability. Hope this helps. : )

I didn't see any information about watts or amps. During the short time I had it I was only concerned about whether or not it would charge my Nexus5 as advertised. It did a fine job. I'm pretty low tech about electronics, so as long as it doesn't make my phone blow up, it's good enough for me.

The BLUE outlet provides 2 amps and the other side provides 1 amp. You have to review your specific phone charging requirments to determine if that is enough power. Generally speaking, most phones and tablets will charge (although slowly if you are also using the phone/tablet at the same time) on the 2 amp side. The units will charge more quickly if they are not being used. This works well if you are in the car and your charge is running low. You can be powered up again by the time you get where you are going. Hope this helps.

This charges both tablets and phones. The ports are labeled, one for tablet, the other for phone. The tablet port delivers a higher charge to recharge tablet faster

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".

A charger should be capable of 2 amps in order to charge tablets quickly or to even gain a charge at all if they're in use. Anything less than that and the tablet will charge so slowly that if you are using it at all it will continue to lose power, albeit more slowly.

After around 2-3 your power will be too low to support anymore. Physically, it would connect, but the amperage would have to be 4-5 times that of the normal charger to provide enough to 7 different phones. 5 volts at maybe 25 amps might do it, but you would fry any of them that where less than the 7.

It will work just fine for either one. The only thing you MAY notice is that, if charging both devices at the same time, the charger might run a little bit on the warm (not hot) side but I don't think so. Regardless, it shouldn't be a problem.

The 2 amp is theoretical for tablets but wor good for smartphones due to bigger batt really it doesn't matter which one you use ....the 2 amp is supposed to charge quicker

No. I have Galaxy Note and Nexus 10 -- both are charging at an abysmal 200mA ...very disappointing.

Compare the amps required for your Android device with the amps supplied in the specifications for this product: http://bit.ly/1d3JTe7

I've plugged my Galaxy Nexus into the 2 amp slot with no problem. In fact, when charging at home, I tend to use the 2 amp charger that came with my Nexus 7 because it charges my phone faster. It has caused no damage.
