Portable Need help with a charger

I'm trying to find a third party charger to test an ASUS X705M for a friend.

Amazon has come up short with exact specifications and eBay seems like I'll be getting it from Eastern Europe.

I need to find something from a reliable source with the following specifications -

19V
1.75A
33W
5.5mm connector

Any advice will be very much appreciated as the warranty runs out on the unit in just over a week and she doesn't want the unit wiped if returned without backing up first!

Thanks so much in advance!

 

I'll have a look tonight - I have a bunch of laptop bricks - most of them are 19v but I'm not sure on the barrel size.

 

Thanks matey

 

I've bought one and will check if it works tomorrow!

Works fine and dandy!
