Did you lose or break the charger for your SpeedHex cordless driver? This 8.6V AC/DC power adapter is designed as a direct replacement. It's compatible with a bunch of models, including the SpeedHex TA414, Speed Hex FlipOut 2, and others like the FOSH2014, FOSH162BP, and RB-FOSH2016. It should also work for tools that use the myACT APS-L010086100L-G power supply. Basically, if your tool runs on 8 to 8.6 volts DC, this adapter has a good chance of being the right fit. It plugs into a standard wall outlet (AC) and outputs the DC power your tool needs to charge or run. Always double-check the voltage, polarity (the symbol on the label), and connector size on your old charger to make sure this one matches perfectly before you buy. A lifesaver if your original charger has given up!
