I've recently been a bit jealous of Festool tool owners, specifically their fancy "plug-it" power cable connectors. More often than not a power tool case (in my mind at least) is there to keep the cord tidy as good tools are rugged enough not to need one and often used tools never end up back in their case anyway. When you are doing a job that requires more than a couple of tools you’ll end up with a spaghetti pile of cables getting in the way, having just one or 2 quick release cables plugged in at once would be a boon for tidiness. I randomly stumbled upon Neutrik power con True 1 connectors, very similar in style to Speak-on connectors that are common on P.A and larger bass amps to deliver the low voltage, high amperage signal to speakers. These power con ends are designed for mains voltage and are rated for 16amps and a capable of being connected and disconnected under load, as well as being made of robust GRP they are IP rated too. I bought a couple to try them out. Wiring instructions are here and here.
I put the female ends on the cable I cut off. I've got a few more tools to convert but it takes less than 5 minutes per tool. Easy
