I'm now back travelling regularly for business after a few years of pretty much leisure only travel with a netbook and iPhone.

I now find myself regularly travelling with a HP work laptop, iPad, work Blackberry & iPhone. I don't mind lugging the hardware but I'm looking for the beat way to optimise powering each device by
1) bringing the fewest mains chargers
2) bringing a portable charger than can cope with the variable power consumption of the iPad, iPhone & Blackberry.

I would imagine my combination of gadgets is fairly standard amongst many posters so how are you dealing with powering your devices when you travel?

I only I have one real constraint, I really don't want a solution that needs me to power up my laptop to feed USB ports to charge the other devices if avoidable. Too much hassle as my laptop has so many boot up security features it takes an age to get going.
