Have my eye on this to power the laptop, charge cell phone, watch
DVD's on laptop, etc. It would be connected to my auxiliary Optima
Yellow Top deep cycle. I would replace the alligator clips that come
with the unit with eyelet connectors to connect it permanently to the
Optima.

It's a 300w pure sine wave inverter, which is exactly what I want. I
can't tell from the photo, however, whether this unit has an "off"
switch - I don't want the fan to be running constantly if I'm trying
to sleep.

Any opinions would be welcome. I'm not connected with either the Web
site or the manufacturer.
