No, I dont. I have a dedicated stabilizer. But yes, that could do that and I should setup 1 for myself. I have few ups around home bought from time to time. Will get one refurbished or something if didnt work.
You have to use USA based vpn server as on GMG its also not available in our region. I bought it for $48 USD.
You can buy it from here if you don't want to use vpn: Dragon Age: Inquisition CD Key for Origin
But remember cjs won't give you game key until the game is released unlike GMG which will give you key 2-3 days before so you can preload.
