Kindle charger--ok for ipad

Hi, can you use a kindle plug connected to the ipad usb cord without hurting the ipad? The ipad plug doesn't fit in the adaptor we have but the kindle plug does. Both have usb cords. I've read comments online, some people say it's ok others say don't do it.

I'm confused. USB is USB. How could one fit in the adapter and the other not fit?

I don't own an Ipad so I don't know if they can be charged via USB but.... If you're referring to this thingy: http://tinyurl.com/d2pu6jz Then yes it can be used to charge any USB device. I've used it many times overseas and have used it successfully with different non-kindle devices. It's compatible with all voltages worldwide, of course you will need a separate adapter plug. They are sold on this website. I works with my Ipod Touch FWIW.

Tom, I'm not entirely clear on how you're trying to connect the "Kindle Plug" to the iPad? I don't own a Kindle, so I'm not overly familiar with the types of charging systems they use. Is the Kindle Charger similar to the one in the link that Michael provided? Is there a reason you don't want to use the Charger and cables that were supplied with the iPad? Cheers!

All "USB ports" are not c reated equal. Make sure you understand yours. I just read that the power produced at a standard USB port is 5 VDC. However, makers of power supplies might use the USB plug because it is convenient, but not respect the standard. My Asus eee pad's power supply has a female USB-A socket but produces 15 VDC. My pad's manual says you can charge it from a standard USB port, but it will take longer. I would imagine that a device designed to be plugged into a standard USB port could be hurt if plugged into a USB ports of a power supply with higher voltage. The page that Michael referenced has a customer review that says it is 4.9 VDC, so it is essentially a std USB port. However, I'm not sure that is what I am reading on the picture. I saw plug-in power supplies with USB ports (I assume standard) for sale at MicroCenter the other day for 97¢. I have an AA/AAA battery charger that fits into a computer's USB port. It says "Input D.C. 5 V".

Lee, You've raised a good point, which is a reminder that Users should ALWAYS check the spec's if they're going to use products with different Chargers than they were supplied with. The voltage on your Asus EEE is typical for Laptop / Netbook power supplies, which generally range from 15-18 VDC. The power supply on my Toshiba Netbook is 18 VDC. The "typical" USB voltage is 5VDC (±0.25 VDC). In the scenario presented in this Thread, I was more concerned with the current supplied by the Kindle Charger. An iPad requires a higher current than many other devices, so unless the Kindle Charger is able to supply that, it could be a problem. For example, Apple does NOT recommend using an iPhone Charger with an iPad. It simply doesn't have the capacity, and will be in an "overload" situation each time it's connected. It's likely that it will burn-out in a short time. Hopefully the OP will clarify the situation, as I'm not clear on what he's trying to do. Cheers!

Short answer: Yes. The kindle USB charger will work with iPad or Kindle, or anything else that charges with USB with the correct cord.

I concur with Nicholas. I've done this myself. My understanding is that the amps delivered by the Kindle plug are a little less than what the IPad plug delivers, but all that means is that your IPad might take a little longer to reach full charge when you use the Kindle plug. This has been my experience. The IPad regulates its own charging internally.
