Re: (ET) new electrics
Don't forget to include an inverter, so (Joe) can use all of his
cheap AC Power tools anywhere on his property. This is an area
where I think GE made a mistake, they had all of the powered
attachments but they used 36volt design, so required large
currents which requires bulky cables. My ET chainsaw for example
has a power cord that is kind of like a garden hose, thick and
heavy. My AC Remington chainsaw runs off a simple 14 gauge
extension cord, much lighter and much easier to manuever. Also the
AC powered tools are already mass produced and "cheap", and most
homeowners already own them, so won't have to buy new ones.
I don't have an inverter yet, but I will get one, It will be nice
to carry my AC string trimmer on the tractor with me and use it as
I need it.
Now if I could get a company to build a decent AC string
trimmer........they currently have good power, but the motors are
simply not reliable, mainly because of crappy bearings. I have 3
dead trimmers, 3 different manufacturers, all with bad bearings.
Lucky for me they're as cheap as they are cheap.
Stay Charged!
