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, ...

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 ...

The physical MagSafe adapter remains unchanged from a pinout perspective (the shape has altered externally from a T shape to an L shape and back again) for almost every Macbook except the 2012 Macbook Air and Retina Macbook which use MagSafe 2; Adapters are available to connect a MagSafe power supply to these machines, but you cannot use a MagSafe 2 adapter ...

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 ...

The short answer is: there's a better chance you want your phone ON than OFF. That's why Apple chose to make it turn on whenever there's a power source available.

The battery is no where near that part - it's in the hand rest portion of the computer. Also, lithium polymer batteries don't really ooze liquids that would travel that far inside the computer, so it's probably the result of a spill near that area or just corrosion (rust) of the contact once the plastic covering has worn away. However, any liquid or ...

If it’s a genuine Apple charger, you should be fine, those are universal. If it’s not (and it’s not unheard of for counterfeit items to be sold on eBay), all bets are off. See for instance Ken Shiriff’s teardowns of iPhone chargers to see what enormous differences there can be among charger designs and their safety: ...

There are only 2 types of connector for iPhones/Pads; the old-style 30-pin & the new-style Lightning connector. The change to Lightning, for phones, is at iPhone 5; prior to that they were 30-pin. The output of a phone/pad charger has only 2 variations, 1A for phones, 2A for pads. Any device needing 2A or less will work on a 2A charger, a 2A device on a ...

iPhone 5, 5S, 5C, 6, and 6+ all have the same ports and wires. I'm a bit confused what you're talking about, all the wires that come with the devices just plug in.

There really isn't any difference, there is no chance of anything bad happening regardless, although if you were particularly worried about this sort of thing, then frankly you would be better to turn the charger unit off at the wall socket first, after which it is utterly irrelevant (assuming you are using a wall charger). If you are charging from a PC ...

Yes. The wattage ratings are maximum and all iOS devices will only pull the current they need to charge. Should a device or an adapter get too hot to operate safely, they will shut off.

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 ...

Also note that a Pro with a completely discharged battery will not be able to start up off a 45W or 60W adapter at first - I know from first-hand experience that a 60W can charge a 15" Pro's battery enough after a few minutes to allow booting.

The original Apple charger has an output limited to 2.1 A at 5.1 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 ...

This can happen when the MagSafe cable is failing, generally at the plug end. As the cable strands break down due to mechanical wear, the power being supplied has to be carried by fewer strands. These strands invariably begin to heat up and become oxidized, increasing resistance and therefore generate yet more heat. This is why your MagSafe is getting hot. ...

Your battery will only take as much as it needs. Thus a larger charger will not harm it.

Apple Charges are universal (worldwide) Every charger has a label that has to say something as following: 110-220 Volt (or 100-240 Volt) 50- 60Hz. Then it is a Universal charger. FYI: The USA system is 110 Volt 60 Hz while the European is 220 Volt 50 Hz. And Apple charger covers both systems. And you do not need a expensive converter or some traveler ...

Assuming that the wall socket is providing power (or the switch for the socket is on) it is normal, or rather common, for power adapters of devices to be a bit warm when connected to the wall socket (mains) without a device connected to the other end (iPad, iPhone, laptop, etc.). In many cases, the charger would be considerably warmer while actively charging ...

In other laptop chargers the pin is of round shape, so that there is no orientation of direction for the connection i.e. always +pin of charger connected to +ve pin of laptop and -ve to -ve. In Apple's version out of 5 pins, 1 pin (middle) is for the battery status which provides a signal to LED to change color red/green. As the connecter is of ...

Absolutely it is safe. It has been designed for that, it does not have a locked in plug, but a magnetically coupled plug for that reason. I have done that on purpose or by accident (tripping over the cable) many times without problems.

The cables go bad so easily, particularly 3rd party. Do you have another to try?

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 ...

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 actually have the same problem but a different solution worked for me: The problem only arose when I unplugged the charger from the MacBook (but not from the power supply) and plugged it back in. Unplugging the charger from the power supply for a moment solved the issue instantly.
