I have an LI3000 Type 2 LI screwdriver, but no charging Craddle. Could someone tell me what the voltage & current (AC/DC) output of the craddle is? This information is usually printed on the part that plugs into the wall. Also, does that craddle appear to have any electronics in it or just contacts. From looking at the inside of the screwdriver all the charge control stuff seems to be in the screwdriver. Thanks much
