For me, if I was working on a site that had no power and wanted to
insure my days pay, the last thing I would rely on is a cordless tool.
I would have a small 1.5 or 2 KW genset (carry with one hand) or a
true sine inverter in the truck. I may still have the cordless but I
surely wouldnt rely on them for my days pay. Too short sighted. An
even further suck factor for cordless tools is many of the chargers
will not perform, or perform at 1/2 power or less, on genset or
inverted (not true sine) power. This means plugging them in to a
generator or low end inverter may result in slow charging or majic
smoke. Buying dedicated 12vdc chargers is a further nudge toward a
good small genset.
