When the phone operating system is off, the hardware still remains sensitive to the introduction of charging power to the 30 pin dock connector. Not only does this help in cases where the OS has frozen and run down the battery past the point where available voltage can even run the system (including the charging circuitry) but it also helps in the more ...

From MagSafe Wikipedia page
Pin 1 - Ground
Pin 2 - V+ @ 16.5 V DC
Pin 3 - Charge control pin
Pin 4 - V+ @ 16.5 V DC
Pin 5 - Ground
The inner large pins are V+ (16.5 VDC). Measuring with no load will give 6.86 V DC; the full 16.5 V is provided to the proper load.
The outer large pins are ground.
The tiny center pin is a charge control pin that assists ...

In my case, the problem was the temperature of the charger. Since it's currently winter in the southern hemisphere, removing the MacBook from charge causes the charger to cool down (since it apparently draws very little mains power when there is no load on the MacBook side). At some point when it is cool enough, it will refuse to supply power when the ...

Yes this is fine (assuming you refer to the 60W Magsafe) and this has been confirmed by Apple to be safe
Although you should always use the proper wattage adapter for your Apple portable, you can use an adapter of a higher wattage without issue.

You can use it, but how much actual charging goes on may be minimal. It depends how much power your MBP is drawing (i.e. if you're doing CPU or graphics intensive tasks, you'll draw more power, thus less charging), but I suspect the 45W won't do much more than slow the rate of battery drain. If your MBP is asleep or turned off, it should charge the battery, ...

Your mileage may vary. Most 3rd-party accessories use inferior parts or less rigorous quality assurance. They may work, they may not.
Paying the extra $10 for the official Apple charger is probably worth it, when weighed against the risk of buying a new iPhone.
Plus, any issues with official accessories will be covered by the warranty.
Basically, it's hit ...

Most of the third party iPhone ones are mostly safe most of the time. However there isn't a good way to tell which ones aren't. Here is a teardown of an Apple one and a clone.
I say most of the time since some of the safety issues are only problems if there are faults. But in a poorly designed one, faults can cause fire and/or shock. Also poorly designed ...

While an iPad typically charges very slowly on a regular USB port, you could still use your MacBook Pro's USB ports to charge your devices. You definitely can charge your iPhone using your computer's USB port.
There also exists an accessory to "plug" a 10W USB port onto your MacBook Pro power adapter called PlugBug. This should be fine for charging your ...

The USB-to-30-pin-dock cables are electrically identical. All of them can carry enough charging current for both devices. The same is not true for the power sources as the iPad gets a 10W supply and the rest 5W.
What power source are you using with the cables? iPads need more power than most USB ports offer to charge with the screen on.

The original Apple charger has an output limited to 2.1 A at 2.1 V.
I occasionally charge my iPad 2 Wifi with the old charger of my passed Palm Pre. It provides an amperage of 1 A at standard 5 V USB voltage.
I don't know if you can go even lower than 1 A, but the standard USB amperage of .5 A is not enough to charge it. It shouldn't be a problem to get a ...

Anandtech has some nice charts detailing the wattage of the iPhone 4S running various apps, which could be a good starting point for you.
You may also want to check out existing kits/projects, such as MintyBoost - they seem to work reasonably well with iPhones. There's a specific MintyBoost page detailing Apple device charging that may also yield some ...

It's not a bug, it's just because the GPS app is using much more power then the charger can deliver. You should check the amp. of your charger. I have one of 2100 mA and I can use my iPad with Navigon while my iPad is charging.
This charger sold in the Apple Store will provide your iPhone enough power to both run the GPS app and charge at the same time.

I happen to have a C8 plug from my PS Vita charger, and my iPad (3rd gen) charger here. I plugged them into each other, and plugged in my iPhone. Sure enough, it started charging my phone.
So yes, this does work fine. C8 plugs will plug into the iPad 3 chargers.

Are all third party chargers safe? No - not even close.
Are all third party chargers unsafe? Same answer.
If you use a charger somewhere where it won't start a fire and you can afford to replace a damaged phone / iPad if it comes to that then I'd say it's worth it to take into account your familiarity with electronics and perhaps decide to get a third ...

This may be a (possibly unavoidable) problem with that particular type of GPS app on that particular device model.
An app using lots of graphics GPU features at high display frame rates in addition to continuous access to the GPS radio plus with the cellular radio power turned up in weak cell signal areas might consume more current than the battery charge ...

The standard iPad/iPhone/iPod Touch cables are identical and interchangeable. As the Apple store item notes:
This USB 2.0 cable connects your iPhone, iPad or iPod — directly
or through a Dock — to your computer's USB port for efficient syncing
and charging or to the Apple USB Power Adapter for convenient charging
from a wall outlet.
However, the ...

A standard USB charge should be enough to charge it, albeit very slowly. It's important to note on a very low charge like this, often it will provide enough to either a) charge when the screen is of, or b) not charge but allow enough to run it without any change in charge levels. In this mode, the charging indicator will always show not charging, as by ...

This will not affect the Mac at all. It will not charge faster. It will not damage your battery. It will not damage your adapter.
Information on power adapters is detailed on Apple's support site: http://support.apple.com/kb/HT2346

The cableJive dockStubz may do the trick. Designed to extend the port in bulky cases, it features a MicroUSB port on the side to charge with older accessories that don't support charging.
MicroUSB should also support an iPad charge, though it may be very slow. See here for someone saying they can charge their iPad with a MicroUSB adapter (admittedly ...
