What is the difference between this 12W USB Power Adapter and the 5W USB Power Adapter, i.e. speed of charging, plug, durability, compatibility?
I have a iPhone 5s and iPad Mini Gen-1 to charge.Best Answer:
An iPad requires at least 10W to charge at full speed. The 5W charger, when used with an iPad will cause it to display a "not charging" message - it will actually charge, but very slowly. Your iPhone will probably charge at the same speed with either adapter.
WRT the plug, the 5W adapter has a US-standard plug. You will need an adapter to plug it into any other country's outlets. The circuitry is universal, so you can use a simply adapter and won't need a voltage converter outside of the US.
The 12W adapter comes with a US-standard plug, but it is removable. You can attach a cord/plug (like those the laptop chargers include) or use Apple's international plugs, if you are so inclined.
WRT durability, I've never had a problem with any of Apple's chargers. But make sure you're buying an actual Apple product. There are a lot of third-party knock-offs that look similar, but are lousy quality. Given that it's often impossible to know until after you make your purchase, I would recommend only buying Apple chargers directly from Apple.
WRT compatbility, These chargers should work with any USB device. Given that a standard USB port supplies only 2.5W, you should be able to use either Apple charger with any device that can charge from a computer's port. I would recommend using the 12W adapter with anything that may require high power of if you're not sure. Fortunatley, they both cost the same price ($20 right now), so there's really no reason not to get the 12W model, unless you really want a very small device.

All of apple's iOS power supplies have been universal switching power supplies so there should be no reason why this one shouldn't be as well. As such, just like with the older models this should be able to take any voltage between 110-230v no problem, although obviously you do need the right kind of plug end for whatever country you want to use it in.

Absolutely. The iOS device regulates the charging, not the Power Adapter.

Will overcharging the ipad mini harm its battery life or decrease it?

I haven't seen the new wall charging unit, but if we assume that the output voltage is 5 volts -- then the charging unit would be putting out 2.4 amps.
Quick calculation to find watts: Volts * Amps = Watts, so 5V * 2.4 amps = 12 watts.

what power adapter do i need for ipad gen 1

Any of the iPad adapters will work for the iPads. You can purchase this 12w adapter and just use a 30-pin USB cable with it. It will draw as much power as it needs to (since the iPad 1 uses 10 watts, it will draw 10 from this).

No!!! The only concern is if it is of a different voltage. The wattage has no affect.

I notice the charger for a Iphone 4 is 5w 5v and 1amp. Wouldn't this charger damage an iphone 4? Surely the faster charging speed is bad for it?Best Answer:
No, it will not damage the device as the device negotiates the correct wattage, voltage, and amperage with the charger

will a 12 w charge an ipod nano 7th gen?

Yes it will charge but i dont know if the 2 amps rate will degrade the battery life. Some batteries have an upper charge rate on ampres and volts; if these are exceeded then the battery loses ability to fully charge and life. Im here trying to find out this myself. Im currently charging my iPod 2015 w/my iPad pro 9.7 charger. It definitely works but...damage?

All Apple power adapters are rated with a AC voltage ranging from 110 V all the way up to 240 V. This way, you can use them everywhere on Earth.

How much faster will this charger charge my iPad3 ?
- Asked by Michael H from Conway
- Flag as inappropriate (How much faster will this charger charge my iPad3 ?)
It won't contrary to popular belief.
The new iPad has its max load info printed on the back of the device.
The faster charge time depends on the new iPad's (iPad 3) capabilities to accept the higher value charge. Over supplying the circuitry when it is not capable can cause fault and possibly fire. A step down feature exists within apple devices to prevent over supply of electricity. When you use a 12 Watt charger on a iPad 3 it will only accept the max load which is 10.71 Watt
The 12 Watt power adapter outputs more voltage and amps than its predecessor at ~ 10 Watt; The 12 Watt is rated at 5.2V and 2.4A respectively so actually the total output is 12.48 Watts. The ability for a device to be charged quicker is usually restricted by the device and in cases where it is not, over supplying power can cause overheating and damage to the device or worse even cause a fire.

Yes. I have the 7plus too. this charger charges the 7plus from dead to 100% in 2.5hr. If memory serves me right, the standard iphone charger charges it in 4hr.
