The first product image (with adapter on its side) notes maximum of 0.5 A at 5 V at each port. Has anybody measured the current draw when only 1 device is attached? How about when two devices are attached?

No, never tried more than one device on mine. However, the reason I bought mine is because I had a chance to connect to one at an airport. There were four of us on it, and we were all happy. We did not mesure the current draw, but we were satisfied with the way the device was working.

The manufacture recommends not to exceed a combined current of 5A. 1.5+2.1=3.6 leaves just 1.4 for the remaining ports. Divide that by 5 and u get less than 300ma.

The specification sheet from Cooper would lead me to believe it's 2.1A combined for both ports as the MilliAmp rating for teh entire recepticle is shown as 2,100MA, not 4,200MA as it should of both USB ports could pull 2.1A independently. http://www.cooperindustries.com/content/dam/public/wiringdevices/BuyersGuides/RBG/B/RBG-B-Sec-14.pdf

Total = 750mA both ports combined. This isn't suitable for charging more than one modern phone at a time (It's very under-powered.)

I tried charging two at once and it didn't work. I think what was really intended is the one mini/micro whatever it is connection on the face is the only charging connection... On the positives, its a neat little device and I do mean little, the power adapter is much bigger than the hub.. I would still recommend buying it just based off its overall size and portability, I just kind of like the thing... Sorry no I dont think its capable of charging two devices at once.

Tablets are no problem. Laptop at same time is probably ok. If you are just charging all 3, it should be fine. But, when running, today's "normal" laptops, (as apposed to high power gaming laptops) can draw as much as 150W. Most don't come near that. Check the small print on your laptop charger for power usage info. I have one PV150 running my DirecTv DVR and a 26" LCD TV with no problem. The other runs a HP 17" laptop. But, haven't tried charging tablets at the same time. What I love about it is it's quiet. No fan.

Measured Draw at 13.2volts is 2.4 Amps, just purchased the product in December and connected to a Voltage/ Amp draw meter and there is no initial "strong" draw, just constant draw at 2.4 amps, this unit is running off a battery storage unit, charge by solar panels, for my fish pond in my Aquaponics System

MANUFACTURER ANSWER:Thanks for posting your question here, ck001! Both ports on the 2 port hub share the available power from the one upstream port.If you need any additional information, please do feel free to shoot us an email at support@plugable.com. We are here to help!Thanks!Regards,RozePlugable Technologies

i do not have difinitive answer; however, if you read carefully the accompaning instructions in some of these adapters, it reads "if you connect more than one device, the charging is slow.i if you use all ports the time to charge will "increase". it will require more time to charge.

Easy. ianker.com (mfr) explains that the white model has ports that handle up to a max amperage but only that specific port. This is "smart" and will handle as much as the device asks for regardless of the port you pick. I have not seen a port max - they imply 8. Some devices must have a minimum amount so with the white model you had to pick the correct port when plugging in an iPad or it would not charge. I think this has a bit more future proofing than the white one so I'm getting it instead.

My understanding is that 2A is the maximum. If you use one usb port, that port will get the 2A. If you use both the current will be distributed. 4A seems too much to take from your car battery anyway.

This is something that could be done, but I would not recommended doing so. Each port is designed to support a maximum of 0.55 Amps draw and a total maximum draw for the entire output of 10 amps. If I needed the extra draw for that one camera I would connect it to its own power adapter, recommending a minimum 2A or 3A adapter. The lower the draw you place on a power adapter, the longer it will live. An ideal draw is 50% or less of rated capacity, 75% considered a maximum. Anything more than this you are stressing the components and will have a lower life expectancy, both the power supply and the connected devices. If things were manufactured the way they used to be (dating myself), everything had a large over design factor so the rating was actually 50% of the theoretical maximum. These days too many products no longer have this over design built in, unless you are talking about military or other specialized use products, at substantially higher cost. It is all about "cheap" while giving the illusion of large output. Do what you want, but please consider what has been stated here. Test your camera to determine its actual current draw, you might find it is substantially lower than rated, or not. Also remember however that draw will vary depending upon duty cycle and environmental temperature. Worth finding out exactly what your equipment uses in all scenarios. I am using this power box for a maximum of ten cameras (each rated at 0.5A) so as to not overload or stress any components. My two cents worth.

Hi M. Prince,Just like the listing note stated, we recommend that you avoid simultaneously connecting five or more of such "self-powered" devices. To ensure a stable connection, the connected devices must not exceed a combined current of 5A. This is especially important for any devices with high power requirements such as "self-powered" hard drives which draw power from the USB port.

You will be using the adapter at a current that exceeds its rating. I doubt that you will damage your device. It is more likely that the adapter will burn out or have a shorter life.

I'm sure that is max for the unit. Using two 1200W devices isn't the problem, the issue would be how many amps they'll draw when in use. For example, if you connected two 1200W grills, it'll not work due to the amps.

I have not seen anything on the device or on the box or in the instructions that says that it is limited to 500 on each port.I am suggest you ask the manufacturer about that because That information is not there to be found.Ask corporate for an answer.

Good question and I don't fully know. What I do know is there is more than 2 amps coming from the wall, or car, so it's not limited at the source. Does it have the right chips to fully deliver that, I think so, but that's just from use. When I use 2 devices at the same time, the 2 amp one always charges faster. Not a scientific answer but it's what I know. Love this product btw.
