Wall Charger - apple, charger


Although the Amazon's product description says: "Newly released! Designed specifically for your Apple iPad," the product that I received certainly says and behaves otherwise. The plastic box that comes with it printed "Apple iPhone 3G Travel Charger", and the label sticker on the charger printed "For iPhone 3G charger, Input 100-240V, Output:5V DC 700mA." If the charger is indeed specifically designed for the iPad, it doesn't say so.



The original charger that comes with the iPad is rated 5.1V and 2.1A, and this charger is 5V and only 0.75A. The output current of this charger is way under that of the iPad original charger. I was running Pandora music app yesterday with this charger plugged in, and seeing the battery level dropped from 88% to 86% in 10 minutes. So the charging power was not even able to keep up with the burning rate (read on for a possible explanation).



After testing with several other USB chargers, ranging from 500mA to 2000mA (e.g., Tekkeon MP1800), I believe that the iPad has a mechanism to detect whether a charger is "acceptable" (as reflected by whether the "battery level" icon on the iPad is changed to a "battery charging" icon) and a separate mechanism to actually be charged. Some USB chargers are rejected by the iPad (either the iPad does not show the charging icon or the iPad may respond by saying "not charging" next to the battery icon. Some other USB chargers are accepted only when the iPad is on the home screen (i.e., without running an app). Once a USB charger is accepted, then it will normally charge the iPad (sometimes I have to turn off the screen to prevent the charging icon from quitting).



The USB charger that I received from Amazon yesterday (the one that I am reviewing right now) is "accepted" by my iPad all the time (the charging icon came out and never quitted), but I suspect actually it may or may not be charging my iPad. As I described, the battery level was actually dropping when I ran Pandora (the dropping rate makes me believe the iPad was not being charged even though the charging icon showed up). However, last night I left my iPad plugged in with this charger. It did charge to 100% (from 90%) this morning.



In conclusion, the output current of this charger does not meet the iPad requirements. At best, it can still slowly charge your iPad like your other USB chargers designed for other gadgets. But this charger may give you the false confidence that it is charging while it actually cannot even keep up with the discharging rate when your iPad is running an app like Pandora.

I purchased two of these while they were on back order expecting to receive an iPad charger. The output and labeling on this product indicates that its an iPhone charger. I had it plugged into my iPad overnight and it provided NO charge. Returning. Save yourself the trouble and don't buy this product to charge your iPad.

Unfortunately this is not engineered for the Ipad but for the 3G Iphone. I received it after it was backordered and lo and behold it was marked for a 3G Iphone. The Ipad has a higher wattage requirement than the 3G Iphone. You can charge a 3G Iphone on an Ipad charger but it will take 2x the time to charge an Ipad with a 3G Iphone charger. I returned it and I am surprised that Amazon is still listing this for the Ipad. The IPad draws 10w of power, while the iPhone charger only supplies 5w.It shouldn't hurt anything, but it'll be slow probably.

I've had a lot of trust for Amazon up until now. This charger is being sold as an iPad chgr and it is not and after reading the other reviews it bothers me that Amazon is still misrepresenting this product. DON'T BUY THIS FOR YOUR iPad!! You will be disappointed with it as well as feeling deceived by Amazon!



I strongly recommend reading any reviews if available and do further research if you see anything negative. I know I can return it but it isn't worth my time so I'll probably give it to an iTouch user.



Totally false advertising!

This item will only give your ipad at max even after plugged in only about a 20% charge even after hours of charging. I havent had this problem with any other cords so I know it is not the ipad itself. Definate lemon wouldnt buy again...

It's not like Amazon doesn't know this charger is NOT for an iPad. All they have to do is look at the product or read any of the previous 8 reviews.



I feel as if I am a victim of a bait and switch.



This item is sold by Amazon, not some associate company.



Shame on you Amazon.



I am off now to return it.



If you are looking at this item and Amazon still sells it as an iPad charger buy one and return it until they get the idea that their customers do not want crap.

I was looking for a wall charger for an iPad 1. This charger does not work on my iPad even though it indicates it is charging as opposed to other devices that definitely say "not charging". It raised the battery level about 1% in 10 hours. It does seem to work on the iPhone and iPods. - Wall Charger - Charger - Apple - Accessories'
