What is the amperage on the output - I don't see it listed? Want to recharge an ipad and I have read that 2.1 amps is faster than lesser amperage. Do amps apply only to USB?

The 175 watt inverter will max-out at 1.46 amps @ 120 volts. I don't understand the part of your question about "Do amps apply only to USB?" -Roger

You wont have any problems. This is a great unit. run any charger just as fast as anything else.

Checked out the Scosche web site and found a reVIVE II - Dual USB Car Charger (USB12V2A) which purportedly has two 1.0 Amp USB outlets. It's anybody's guess whether this a different charger than what Amazon is selling, but it appears to be better equipeed to accomodate two iPhones at the same time.Hope this helps!

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.

I really wish people would look more closely at the product. I myself am trying to find the same information as you and almost bought this unit. However, taken directly from the manufacturer's website (Accell), I found the following: USB CHARGING: 2 Ports, 5V, 2.1A Shared. So unless the manufacturer incorrectly described it's own product, this, just like most others, have a total of 2.1A for all usb ports. If using both usb ports at the same time the 2.1A will be split, reducing the charging time of 2 devices (ipads, tablets).

From the product description: Two front-facing 2.1-amp USB outlet for charging iPhone, iPad, smartphones, and E-Readers. As with most dual port USB charging devices, if you plug two devices in, they both charge at half the charger's capacity, i.e. one amp each.

Dear Karen:Any device or adapter that can provide you with an output of 1.5 Amperes through an USB connection (v.g. Your laptop or an usb wall adapter) will help. Do not forget it takes about 6 to 8 hours to fully charge with 1.5 A and maybe a little less with 2.1 A (which an iPad wall charger may provide). If you are in Europe any local usb wall charger with 1.5 A will do.

The amperage is 1.5. I believe that it will charge an iPad. I charge my Samsung Galaxy S4 active which uses 2.1 amps if I charge it with the charger that came with the phone. I would not think there would be any concern charging the iPad.

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.

'Over-amping' a device is impossible by the laws of physics. So no worries there. The amperage listed per port is the maximum that port is capable of supplying. A device will attempt to consume the amps it was designed to up to the limits of the port it is plugged into. More amps means faster charging.This is all before Apple enters the picture because they do strange things to try and force their customers to buy only their products. So a 2A 'apple' port may not supply the full 2A to non-apple devices and vice versa. Unless Apple got their act together which I doubt...

Drew. There are two outputs with different amperages. 1 and 2.1 amps. Look at the picture above. If your phone charger is lower than 1.75 amps, I would use the 1 amp, just to be safe. If it is above that, it will charge faster on the 2.1 amp output.

I use this to charge the iPad 2 daily. Please note, it requires 2.1A for the device to charge. Lower 1A chargers or standard PC USB ports will not charge an iPad 2. It is recommended you get the 10W or 12W Apple chargers, as those are guaranteed to charge the iPad2. I also use this in a iPhone 4S and iPhone 4 to charge and Sync.

No, I would look for a 2 amp charger. It will say made for iPad on it. This is a 1 amp charger for iPhones and iPods.

There seems to be some erroneous advise posted here. I thought it advisable to repeat this:I own an iPhone 5s. It does not require a 2.1 amp charger. In fact, it will not charge faster with a charger rated above 1 amp.Also: the Apple Brand charger included in the box with an iPhone 5s purchase is clearly marked "5v, 1.0 amp".Fact: An iPhone will only draw a maximum of 1A of current, no matter the charger.

According to the specs, it will output 2.1 amps to each USB port--the same output of the iPad 2. The charger for the iPad Air is 2.4 amps, but this should charge one (if only a bit more slowly.)

Not sure about amps, but I have found that it will charge my iPhone, but not my iPad. Also, will run two 2.5" external drives (not ssd, which should run on less power) with no problem. Another user claims 7 external drives. I have a WD Scorpio Black drive and a Seagate FreeAgentGo drive attached and running flawlessly while the Satechi is plugged in.

The outlets are marked 5V1A or 5V2.1A which simply means 5 volts 1 amp or 2.1 amp. All outlets will charge most phones as they typically require only 1A of power while iPads and some tablets require 2.1A of power. You simply plug the USB end of the power cord into the correct outlet. Refer to the manufacturers recommendations for the correct outlet. The unit will work in a 120-240 VAC 50 or 60 cycle environment which means it will typically work anywhere in the world and on board almost all ships.

Do you mean the output voltage? If so, it outputs USB voltage (5 V DC at a max of 2 amps). If you're asking about the capacity, its 5,000 mah.
