Can the AC Plug section be used on other power adapters?
I bought a MacBook Air while i was in the United States. The AC Plug section is the standard two pin american version. Is it possible for me purchase this adapter and substitute the ac plug on this (3 Pin UK) to the adapter for my MacBook Air?

Yes, the iPhone 7 Plus will charge quite a bit faster with the 12W power adapter. How much faster depends on some factors, but generally it'll cut charging time by about ⅓, which can save over an hour on a full charge from empty.

You can but it will charge very slowly. With the iPad screen on you will likely not see any the charge increase at all because the power drain of the screen is enough to counteract the power being received from the charger.

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.

how many amps is the 12watt charger fo ipad air?
- Asked by William P from Manildra
- 11 23, 13
- Flag as inappropriate (how many amps is the 12watt charger fo ipad air?)
When charging an iPad Air, the ~70% efficient 12W charger supplies 2.4 amps on the USB port, draws 0.1 amps from a 230V wall socket, or 0.2 amps from a 110V wall socket.
Older iPads, and iPhones, draw less power, and thus the charger draws less current from the wall.
When not charging anything, official Apple chargers draw less than 0.2W, which is 0.002 amps from an American wall socket. Over the course of a year, this amounts to 1.8 kwh 'units' of electricity, costing less than 10¢.

- Asked by David H from Pacifica
- 11 14, 13
- Flag as inappropriate (will iphone5 adapter charge ipad air)
Yes it will, but it will take a long time to charge and your charging cube will get fairly hot. It's putting out a little under half the power that the standard iPad charger does (5W compared to 12W), hence those side effects. So YES, it will charge your iPad (slowly), but NO, it's not recommended. Personally I would only do this if you were in a jam and had no other charger available. Although in technicality, it is a generic USB charger, charging any device powered by 5V USB.

Yes you can. Please refer to the compatibility list in the product description, it states that the 12W USB Power Adapter is compatible with the iPhone 5S. I personally use the 10W adapter to charge my iPhone 5S, but as soon as I pick up the the new iPad Air I will use it to charge the iPhone 5S as well. It will charge your iPhone 5S faster than the 5W adapter iPhone 5S comes with.

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.

My charger stopped working. Was it because when plugged into an extension cord it always felt hot? Is an extension cord compatible with this charger
When using an extension cord, the charger would get very warm.Best Answer:
The (over) heating of your charger when on a extension cord may be caused by thermal insulation from the surface that the charger is resting on or under during operation. If it is resting on a hard, cool surface, the charger can dissipate heat into moving air (convection) and into the cool surface (conduction) at about the same rate as the charger produces it, and it doesn't overheat.
If the charger/adapter is plugged into a strip or wall outlet, it will have maximum surface area in air and can cool by air moving past (convection).
A problem can arise if, because of the location the charger/adapter that extension cord will allow, the charger is resting on a thick carpet or an upholstered surface or bed, or worst of all, covered under a pillow, blanket, or other fabric. Now, convective or conductive heat loss (or both) will be reduced and the charger can get very hot reducing its useful life, and if completely insulated, risking a fire.
The extension cord rated for the input of the charger isn't the problem, but the extension allowing improper location of the charger itself, is.
Is it surge protected against mains spikes?
- Asked by Charles B

- Flag as inappropriate (Is it surge protected against mains spikes?)
I don't know for sure about this particular unit, but typically power supplies don't have meaningful surge suppression built-in. I always use an external surge suppressor.
For what it's worth, most surge suppressors become less effective over time, as the process of clamping spikes erodes the metal oxide varistors (MOV) most frequently employed by the devices.† So you can see that it doesn't make much since to incorporate surge suppression into power supplies (as they'd lose the ability to suppress surges eventually anyhow).
This article has a fairly accurate information about surge suppressors (you'll have to build you own URI, however, cause this site doesn't allow me to enter a functioning URI; remove the space before the first slash):
† MOVs aren't the only technology used to clamp power surges, but they are compact and economical, which is why they're most often used. Larger, bulkier, heavier, more expensive components often have longer lifespans than MOVs, but they all have limited lifespans.
