I have done some research and the 6 hour charger that came with the AA batteries seems to be the best and quickest I am going to get,the batteries have so far lasted 8 days is my Bluetooth keyboard and I am happy at that,,thanks for your comment matey.
no prob. I haven't been happy with the lifespan of the rechargeable AA's. Not enough to convert transmitters over etc. Sorry to say the Duracell's still get my vote.
