Hi all, I'd like to know if anyone knows what kind of amp the razer blade 14(2013) uses on normal use. I want to know thus because I'm thinking of buying an external battery (40.000 mah, 19V at 4,5A). I know I can see on the power adapter what kind the adapter provides. But since the adapter is used for all razer blades, it doesn't mean a lower Amp won't recharge my razer. If anyone could help me out it would be much appreciated. If anyone has an external battery which you use for your razer blade feel free to share your experience!
