I am going to hazard a guess and say that the 120 VAC to 19.2 VDC charger
requires a good sine wave for operation. It could be that both the inverter
and the honda genset (I believe it has an inverter also - or at least the
web site said so) power output is a modified sine wave that does not get
correctly inverted to 120 VAC.

Perhaps he could try a pure sine wave inverter.... Mucho dinero!

Correction/addition - what I should have said is that the fuse on the
110 VAC charger blows on both the inverter and the Honda - that's why
the battery doesn't charge.

A friend bought a 19.2 v Sears cordless drill for use on his boat.
He's cruising now in Aust so no 110 VAC wall power. The charger won't
charge the 19.2 VDC battery on either his inverter or his Honda
generator. Sears doesn't have a 12VDC charger so now what.

Any ideas why and how to fix this ? Any possibility of a generic
charger that runs on 12 VDC? I don't know what the 110 VAC charger
puts out - maybe 25 V ??

Ny the way the cheapest option may be a new drill :-)

My DeWalt will charge on little cheapo inverters like you can find at
WalMart.

what would happen if he put 2 12v batterys in series & made 24 volt charger?

Add a back up light bulb in series to slow the charge rate and it will work
just fine, as long as he wont leave it on all the time. A much smaller ( dash
) bulb most probably could be used as a trickle charger.

A smaller battery ( Big lawn more ) with a DPDT, switch and a light bulb in its
charging circuit would be a good bet.
