what is the maximum current for this adepter?i have a macbook charger needs at least 4A 12V to worksis Ur adapters could work with it...?

The transformer on this unit is rated at 1 amp. No way will it handle 4 amps.Bob

I don't know the answer to your question, but I have used it to charge my laptop and iPad....works fine.

According to the manual, the AC/DC adapter should be 4.5 V, 150 mA, center pin negative. Be careful of what power supply you buy. Some do not hold a constant voltage or current.

This has two outputs. Ones is marked with an "A" is for Apple devices. the other is marked with "NA" for non Apple devices I/e Samsung, Android or Other. This puts out 2.4 amperes max at 5.2 volts max. if your device falls at or under these amounts, you should be fine.

As far as I know, the 60W charger/power supply that ships with the Macbook Pro works on 120 or 240 VAC electrical systems. I assume you will have to buy an adapter to connect your charger to European style plugs.

The apple products themselves or the block on the macbook adapters convert the voltage internally. So you just need the plug adapter. This package is standalone for charging your Apple stuff abroad; when I was traveling I literally just used the plug adapter on my Macbook's power cord block. I hope that helps!

In what capacity won't it charge, if you are using a computer it should be fine, if you are using a ac wall charger then it probably isn't the proper AMP rating to charge it.

Remember, this is a 4 amp unit. That means that any single device which needs less than 4A to charge, will be charged.... as long as that is the only device attached. If you have other devices attached, they will be drawing some current, usually up to 900 mA for a USB3 device... sooo something like an iPad may not be able to draw enough current. Most other devices should be ok.

12V should be more than enough. I believe the power adapter I used was only 3.4V (or at least not more than 5V), and it worked perfectly.

Hi Actually your laptop need 45W (19V 2.37A) and this charger Output: 19V 3.42A. so the output is more than you need it, its working but not good for your laptop and Hardware..... ,search to charger output 2.37 A Best Regards Eng.Yasser

It should be, the only spec that doesnt match is the voltage which is 1.5 and 1.35 on macbook pro, im not entirely familliar with macbooks so I cant say if it matters.

I charged my US MacBook with this in India. Worked great. MacBook power supply brick supports both 110/220V. Make sure your power supply can handle 220 or it will fry it.

The voltage would be correct the only issue would be if the tips match up. I can't be 100% sure , but I don't think this adapter will fit that model.

Hi Roge,I used it to charge my Macbook and 2 mobile phones at the same time and everything fine and still working :)

Most PC's and chargers limit the current to about a 1/2 amp. That's due to the USB 2 spec. There are a few, such as Apple, Kindle, and others, that charge at higher currents. I would have no reservations using this extension at 2.1 A. Go for it.

Prior to answering, I carefully reread the instructions. No where is this question answered or addressed. I simply don't know. Technical info from instructions:" Power requirements: DC Adapter: 9vcd, 500 mA. Sorry!

Apple recommends using a 60 watt power supply for macbook airs as the 85 watt is designated for the MacBook Pro. However, it also states that the computer knows how much power to draw so using a charger that is higher wattage than recommended is completely fine also. It will not damage the computer.

Wish I could help but I bought this adapter for a USB Hub. I wouldn't know about it powering much else. Best of luck in finding what you need.
