Question about the charger


New Member
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. :)


... 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). :)
