For those of us that benefitted from Amazon $25 off Bosch tools deal at http://www.ozbargain.com.au/node/84949, Power Tool Specialists has on clearance the 240 volt versions of the chargers needed, as well as spare batteries, all with free shipping.
I know el cheapo stepdown transformers can be had for $25 - $30ish on ebay, but they reduce the portability of the solution by having to lug the transformer around with you as well as the charger.
Their complete clearance page (with other brand chargers, batteries and tools as well) is http://www.powertoolspecialists.com.au/filterShopProducts.do…
Direct 240v Replacement for the BC430 110v 30 minute charger that comes with the CLPK27-120 10.8V/12V combo is the AL1130CV - $49 free shipping
http://www.powertoolspecialists.com.au/loadShopSingleProduct…
Cheapest I could find on ebay for the AL1130CV above was about $70 with shipping but from the UK. Australian prices were $105 + shipping from Sydney Tools, one of the few places that sell the charger by itself.
Spare battery for the 10.8V/12V models such as above is $49 free shipping. Available for same price elsewhere without shipping - http://www.powertoolspecialists.com.au/loadShopSingleProduct…
240v replacement for the 18 volt battery charger is $79 free shipping - http://www.powertoolspecialists.com.au/loadShopSingleProduct…
Spare battery for the 18 volt models is $99 free shipping. Available for same price elsewhere without shipping - http://www.powertoolspecialists.com.au/loadShopSingleProduct…
Not sure if this is more suited to forums or not, as it's clearance and quantities are unknown.
Hope this helps someone.
Just saw those links myself.
Ended up buying a $26 step down off ebay however.
Opened the bosch charger today, and has a 170v cap, so wont like 240 at all.
Curious to see what is different between the 2 models.
Was hoping I could just supply 12v after the US step down, but less effort with step down.
