Honestly I think it's stupid to use other batteries on hitachi tool until I tried my mate's hitachi framer.

It just shoots so smooth, sinks nails into anything in a stealth and solid way. And its bump fire definitely outranks all other battery framers on the martket, fast and consistent.

With the intention to leverage from hitachi's framer while staying with my current platform (I mainly use makita and milwaukee), this little gadget is launched.

Maybe you have more ideas with how to use it, but whatever that is, I've built this to last. It's from abs and only uses thick gauge copper pin, galvernised screws/springs, with latch just as the original hitachi battery do. And on this ground, it comes with 1 year warranty, easy as.

Note that some models I have both colored version and plain black version, please leave me a note if you are particular about colors, otherwise I'll dispatch randomly.

Disclaimer: all adaptors can only be used between your tools and batteries, they are not designed to be used with the charger. And logically if you got the charger, you should get the adaptor the other way around right? :)
