I would assume so as long as its a charger that works on the 3GS. I have a couple of third-party dock devices and had a car plug for my original iPhone that don't work on the 3GS. But my Apple-branded cables work on both.
Can you charge iPhone with iPad charger? Can you charge the iPhone with the iPad charger? Traveling will be easier with only one charger.
From what the techs were saying ... Yes you can use any charger that works with the iPhone, but won't charge fast. The best way to charge is using the supplied adapter or using a full powered USB 2.0port on your computer.
i buy my iphone 3G and 3GS from singapore , can it's charger charge the IPAD i buy from U.S ? i heard there maybe some different voltage , 220V and 110V
All the charging bricks apple makes are universal voltage, meaning they will work plugged into any outlet providing 100 to 240 volts AC. It still outputs the world standard 5 volts, so yes it should work just fine, but it will charge the iPad more slowly.
Its been hit and miss for me. My car stereo and cigarette adapter do not work. One USB port on my computer works, the hub does not... etc etc.
The actual USB cables themselves are the same thing as far as I know, the only complication with the iPad is that the screen means that some USB ports can't give it the power it needs.
Does your car stereo and cigarette adapter charge your iPhone 3G or 3GS? Many (most?) car stereo iPod cables and many (most?) iPod cigarette lighter chargers charge via the 12v Firewire pin found on older iPod models. Background: When Apple first released the iPod with a dock connector, they provided TWO power pins for charging within the 30-pin dock connector. One pin was designed to be used with a Firewire port (which is 12v) and the other pin was designed to be used with a USB port (which is 5v). For several years, all iPods made continued that same tradition of supporting both charging pins. However, in 2008, with the release of the iPhone 3G, Apple DROPPED support for the 12v Firewire charging pin. They also dropped that pin on subsequent iPod models. The only iPod model that continues to support the 12v Firewire charging pin is the iPod Classic. Anyway, since a vehicle's standard electrical system is 12v, the majority of car stereo manufacturers and iPod cigarette lighter adapters simply designed their products to use the 12v charging pin. Oops.... Apple dropped support for that pin in MOST iPhone/iPod/iPad products since that time and now those 12v chargers won't charge the newer devices. So, the most likely reason your car stereo or cigarette lighter adapter won't charge you iPad is because they use 12v, not the 5v USB that the iPad requires. Slowly, manufacturers are figuring out they need to change their products to support 5v USB charging on that different pin. But, in the meantime, you can use one of these to correct the problem: http://www.scosche.com/products/sfID1/210/sfID2/318/productID/1667 That device (and other like it) convert the 12v pin power to 5v and send it to the appropriate pin. And, for those interested, Scosche also offers USB cigarette adapters that support the iPad: See that 2.1amp port, that one is for the iPad! http://www.scosche.com/products/sfID1/210/sfID2/318/productID/1921 Mark
A pc USB port is far from high powered. Let's clarify this. Pc/mac - 5v @ 500ma iPhone power brick - 5v @ 1000ma ipad powerbrick - 5v @ 2100ma
According to apple you can not use the same charger for the iPad as your iPhone. The wattage is different. It may appear to work but you will not get the proper full charge. The iPad charger is a 10 watt charger and is larger than the standard iPhone or iPod charger. It also takes longer to charge a iPad.
But can you use the iPad power brick to charge an iPhone or iPod? Will the 10-watts fry the iPod? When travelling, it would be very nice to only have to carry one charger.
I've been charging mine in the car whenever im on the road. Works with the USB car adapter I bought from frys.
Yes. The 10W iPad power brick works fine with the iPod or iPhone. (It even says so on the apple website).
Is an iPhone charger okay to use if I just don't want to use battery power for extended uses? I'm not really concerned about charging the battery on the iPad, just want to make sure I don't screw something up. What about the USB extension on my iMac keyboard, would it be okay to use that in line with the iPad charger so I have a little more cable?
Can you point me to where it says this on the apple site? On their store site, they only list compatibility with the iPad: http://store.apple.com/us/product/MC359LL/A?fnode=MTc0MjU4NjA&mco=MTc0Mjc1NDQ
Here's a question: Does the USB port on the MacBook Air that has higher power output for the external SuperDrive charge the iPad?
So Many replies .... so many different answers Take mine for what it's worth - from a former Radio Amateur. The voltage will be the same in any USB power brick - it's the deliverable wattage in this case that matters. Imagine a stream of water. You can imagine Voltage to be how fast the stream is going and the current (amps or milliamps) is like how big a cross section the stream is . The iPad battery is a bucket that has to be filled. The iphone charger puts out a stream going 5 volts fast but it is a thin tiny stream. The iPad charger puts out a stream that is also 5 volts fast but it coming from a firehose. Which one will fill the iPad battery faster? Right. Both will work but only the iPad charger will fill the battery in a reasonable amount of time. The iPhone charger puts out a 1 Amp wide stream and the iPad charger puts out a 2 Amp wide stream. Your computer USB port puts out a stream that is only half an amp "wide". Hope that explains it.
