how many amps does the usb put out with only one devise charging?

According to the product manual: 5volts / 500mA each port.Charging smartphones is easy. It will take a long time to charge larger devices such as tablets.

Average is .5A each port, design up to 1A max since can charge an iPad2 pretty fast. I have no problem charging an iPad2 and Nexus 7 at the same time.

Short answer: 0.08 - 0.10 watts. I measured it with a Kill A Watt Model P4400 while charging a Kindle.

It uses a standard USB out for both outlets. One is 1amp and the other is 2.1 amp. It charges my IPad Air and IPhone 5s easily and can do so at the same time.

Usb is 5Volts with .5A maximum draw. My multimeter won't even measure the current it's drawing so I'm not sure the exact wattage. So by using the above figures... 2.5 watts maximum although I guarantee it's definitely less than that. Hope that helps. The actual unit itself has no power listing so that's all I can figure for that.

A USB port uses a max 500ma of +5vdc power = 2.5 watts. Thanks for using AnswerParty!

Input: ac 100-240v ~50/60 hz 0.15a Output: dc 4.35v~ 350 mA~ +/-50 mA USB 5.2Vd.c 800 mA That's what's it shows me on the charger

pc usb ports typically put out 0.5amps. these power packs can do 1A and 2A, it probably can.

Yes - "Two high-powered USB charging ports with 3.6 Amps of charging capacity" I bought this and have no issue charging two of anything (including ipads) - love the product!

my ipad charger says 5.4v - 2.4amp. this unit has two USB's one is 1amp and one is 2.1amp output.

Don't know, don't have one. I use it to charge Logitech keyboard. Connection does not appear to be iPad anything compatible.

It seems to be a universal adapter, so if your devise has a micro USB plug it will allow it to accept the standard USB plug. It works for my tablet. Also, it is cheap.

I would check with Wagan to be sure, but as near as I know the output from any port is standard USB at 2.1 amps. I hear some Samsung devices have problems due to their proprietary wiring of USB.

The first answer is a bit off, because they did not consider the step down from the power supply at 12V to the USB slots at 5V. The power supply is 5A at 12V, or 60 watts. The 9 USB slots provide .9A each at 5V, for a total of 36.5 watts. Add the 2.1A at 5V for the charging slot, and you have a total of 36.5 + 10.5 = 47 watts. This is within the capability of the power supply. So, you should be able to deliver the full rated power to all of the slots simultaneously.

This is Levin Service. Both the USB outputs are 1A. Two devices can be charged simultaneously by 1A. But the output power is 2A if only one USB outlet is used. That makes the power output better suited to a tablet. Thanks for your concern to Solstar.

I can't give an exact number, as I use it casually, but charges up quickly plugged into a USB

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.

Remember, this is a 4 amp unit. That means that any single device which needs less than 4A to charge, will be charged.... as long as that is the only device attached. If you have other devices attached, they will be drawing some current, usually up to 900 mA for a USB3 device... sooo something like an iPad may not be able to draw enough current. Most other devices should be ok.

Although Cooper's website doesn't specify explicitly, this outlet is most likely 2.1 amps shared between the two USB ports. Most USB power adapters rate their output as a total - that is, the combined maximum current. That means that the 2 USB ports "share" the maximum current supplied by the adapter circuit. So, two iPads plugged in simultaneously would likely charge at slow (overnight) rates, while one iPad would charge more quickly.
