Charging my Galaxy Note with a 0.7A charger from Galaxy S2

Hi, I just lost the charger of my Galaxy Note but I have a charger of my last Galaxy S2 which still works fine but it has only 0.7A output. I remember Galaxy Note comes with a 1A output charger.

So is it safe to charge my Note with that S2 charger which has lower output A?

Thank you guys!
