I would reccomend a lab style powersupply. With it you are able to set both voltage and current. You probably will fine it suite usefull in many situations later. Dont buy the cheapest økes om ebay, as they probably agent delivering clean poser for LD use. (My psu have had a few diodes pop for no obvious reason bit dirty current. Saging a few USD have become expensive).
Using tablet to write is a bitch.
