Question about the charger

[smookeyjoe11]

Hi all,

The Surface Pro comes with this 48W charger and no one has written about its specs in detail.

Does anyone know the output voltage of the charger?
I guess it has to be 16V or 19V, but as the surface pro isn't available in Germany yet, I have to ask this question here.

I was thinking about using an external notebook battery like this one Amazon.com: Ultra Capacity High Quality 33600mAh Portable Charger External Battery Pack Power Bank Charger For Laptops and Notebooks - Compatible with Dell HP Sony IBM Lenovo Samsung Toshiba Acer Compaq Fujitsu Gateway Lition Asus: Cell Phones & Acce
But it depends on the specs of the original surface charger.

I would appreciate it if someone could measure the voltages of the adapter.

Thanks in advance.

On the charger it shows the following:

Output: 12V - 3.6A, 5V - 1.0A (I assume for the usb port)

Thank you very, very much. This helps a lot

... and since the charging port is very new, I suspect that no vendor of external batteries has a "tip" for it.

I'm planning to use the "tip" of an charger i bought on ebay and attach it to one of the adapters that come with the external battery. If this works, i will be able to use the surface pro for about 8-9 hours (or even longer).

Thanks, I have also been waiting for a confirmation on that. The 5V - 1A is for the usb port which is a little unfortunate as a 5V - 2A port for have been more useful. This can now be updated http://www.surfaceforums.net/forum/...2884-surface-rt-pro-power-charging-specs.html.
