Since the iPhone chargers are rated at 5 amps and iPad chargers at 10 amps, this recepticle would take much longer to charge at 2.1 amps. Correct?

M. Miller, the information you base your question on is wrong. I see in another comment you made, you state "the amps ratings come straight from Apple". No doubt you mis-read something there. HERE is a link straight from Apple explaining the various charger modes/power levels (watts and amps). https://discussions.apple.com/docs/DOC-3511 Note: This charger is rated for 2.1A (10W total divided by 2 ports). Either port will charge an iPad or new iPhone. Plugging both in probably results in reduced charging rates for each (until one device is fully charged and stops drawing power). M.

These chargers are rated at 5 and 10 watts, not amps. That means that the Apple adapters supply about 1 amp for iPhone and about 2 amps for iPad (or 3 amps for the latest, larger Apple power adapters). This Cooper outlet is rated at 2.1 amps for the USB ports, so that's about ~10 watts (2.1 amps x 5 volts). An iPad should charge fine, but might not charge quite as quickly as Apple's larger 15W (3 amp) power adapter. In my experience, a 3rd-gen iPad takes about 4 hours to fully charge using a 2.1 amp USB adapter.

It seems like it does take longer to charge an iPad, however, mine will fully charge overnight

I don't know where you got this info, but the high capacity chargers for both devices are rated at 5VDC, 2.1A. So NO. And, if you charge at a faster rate the battery will fry!

No, the first two (5 and 10) are Watts, not amps. At 2.1A, this provides about the same power as the 10W iPad charger (multiply by 5V, which is USB standard). I have this outlet and it does seem to charge at full rate.

I don't know why you need more powerful charger for iPad as this will perfectly do the job. if you think this is not enough, try this "PowerGen White 4.2-Amp (20 Watt) Dual USB Wall Charger Designed for Apple iPad & iPhone". I believe this is more powerful and definitely will suit your needs.

Hi Jason,To be totally honest with you I can't tell you exactly seeing I don't have an iPad air, however the charger is designed with it's smart charging and fast charging capabilities that it will charge it as fast as the device allows it to be charged at. I have cut 2 1/2 hours off charging by battery pack with it. It is truly the best charger I have had. I actually use it on top of my nightstand instead of plugging it directly into the wall. Overall Jason, is recommend it if you want good quality and a fast charge.

I haven't measured it with a meter, but my iPad charges as fast as using the standard 2.1 amp charger so I'd say it does. If you charge an iPhone or iPod it charges faster than a standard 1 amp charger? You don't have to worry about too many amps - the device will only draw the current it needs.

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.

The charger works very well, at 1 Amp and 2.1 Amps. And both together simultaneously also. Your device is a separate issue, and it's function depends on the cord you have and your device's amp requirements.

The TR7740 should be producing 1 amp +/-, much like a car phone charger. My only suggestion is to try another cord with your iPhone. As for an Ipad, the newer ones I believe require 2 amps to charge in a reasonable amount of time. I use the TR to charge a Samsung tablet (restarting helps after plugging it in), but it does take overnight, 8 hrs or so.

Yes, I used it to charge my ipad2. This is a smaller charger so it might not recharge it 100%. I would get the 12000 which would recharge your iPad 2 one and a half times!

My iPad 2 charges fine. According to Wikipedia, iDevices charge like this: "When D+ = D&#8722; = 2.0 V, the device may pull up to 500 mA. When D+ = 2.0 V and D&#8722; = 2.8 V, the device may pull up to 1 A of current. When D+ = 2.8 V and D&#8722; = 2.0 V, the device may pull up to 2 A of current." I measured my USB charger just now (purchased a few months ago) and I got these values in order: 5 V , 2.8 V, 2.0 V, 0 V. This corresponds to D- (pin 2) = 2.8 V and D+ (pin 3) = 2.0 V. This means an iDevice would limit its pull to 1 A. The problem with this is that it follows Apple's method of telling a device how much power is available. So other phone/tablets may not know how much is available and will only pull 500 mA. For my phone, I purchased a special USB charging cable which shorts the D+ and D- pins on the phone side (NOT the charger side). This tells my phone that it can pull more than 500 mA. Using this method, I'm not sure how the phone knows if it can pull 900 mA, 1 A, 1.5 A, or 2 A.

Probably not... remember the max amp is 5. The iPads draws 2.1A each while the iPhones can be charged via 1A. Maybe you can charge 2 iPads and 1 iPhone or 3 iPhones and 1 iPad. I don't own iPhones so don't know if they can be trickle charged like my Android phones; if yes, then you can slow-charge more iPhones. If you want to charge them all without worries, I suggest you get the 8A 5-port charger for your needs.

I believe the higher AMPs may charge devices more quickly, depending upon the device. However a smaller AMP could take longer to charge a device. Sorry for confusion. Maybe someone could answer this better than I.

The USB ports have a combined voltage of 2.5 amps. So with one connected you get all 2.5. With two connected you get around 1.5 amps each. It will charge but not as quickly as with just one connected. The AC Outlet works independently. So I currently have an iphone, and an ipad connected to the usb ports and a bluetooth speaker recharging on the AC outlet. All 3 are charging, albeit slower then if fewer devices were connected. Short answer is YES.

Yes. An iphone charger is 5W, and an iPad2 charger is 10W, for 15W total, so you should have enough current.
1407311
Yes you can charge an iPhone 5. I haven't seen any over heating when I've used the 2.1 amp. The 2.1 is suppose to charge your devices faster. It is suppose to work best with the devices that have the 3.0 charging ports, but I've used it on my nexus 5 and it charges it a lot faster.

one on left is 1 amp is for iphone, one on right is for ipad - and yes it can make a difference - ipad won't charge on 1 amp and the 2.1 is too much for some iphones - I take a white magic marker and put a dot on to identifiy the 1 amp

No. The charger would be damaged if your device needed 2 amps and the charger only provided 1 amp. The 2 amp rating means it could charge 2, 1 amp devices at the same time. I've used it many times without issue on a variety of devices.

Everything in the specs says that it'll charge it, but it's going to be slow. The standard iPad wall charger is around 2A depending on which model you have, and since this one has an output of half that, it'll take twice as long as normal to charge. The thing is that it has a 2200mAh built in battery which is smaller than the one in an iPad, so it won't fully charge it and you'll have to wait 10 hours to recharge the battery but if I were you, I'd get another external battery, like a 10000+mAh battery and use the solar panel to recharge it once it's dead. Sure, more losses, but I think it'll work better for you.
