My van's 300 watt inverter is going on 3+ years.

Only lately has my battery starting to drain too fast. Not sure if the inverter is starting to go, or if it's the two laptops, battery charger and power supplies I leave plugged in.

I'm thinking of adding another battery, just need to find a battery box that is sealed to install inside the van that won't blow up if I light up.

I use a 100 and 300 watt in my 99 F-350 with the engine running and not
running without any issue...

Hmmm... At first I had an '84 Chevy Van w/14'x7'x7' box on the back with a
1000 watt inverter.  Now I have a 2004 Ranger with a 100 watt inverter.
I
have never used the inverters with the motor running, though, so it won't
affect the alternator.

be careful using inverters.  I've used several, on two different
trucks in
my span here,
and burned out the alternator in short order in both trucks.  One was
a
Jeep
Grand Cherokee, the latest a Ford Expedition with the high output
alternator....

Running too many amps through the inverters puts a REALLY heavy load
on
the
alternator...

I've used an inverter in the past to power laptop, trango, canopy,
routerboard and tranzeo setups in varying degrees.

I'm convinced that frequent usage of the inverters kills the
alternator.
Now, I just leave with a laptop fully charged and a couple of charged dewalt
18V batteries that power my radio setup.  The dewalts last from 1 to 2

hours
which is more
than enough time.   If we're surveying at a customer's home, we use
their
power to
power the radios and recharge my laptop :)

I use a 100 watt inverter that plugs right into the cigarette lighter power
port.  May not power the laptop (haven't tested) but the CPE will stay
on
for much longer for an hour.

What is the best way to power a 12-volt radio for 30 - 60 minutes
before requiring a re-charge? (solution must be re-chargeable via
auto
adapter)

We are wanting to use an actual CPE radio with a 19dBi panel
antenna, connected to an iPAQ/Axim so we are needing a re-chargeable
power source for the radio.

BTW, we tried a 9-volt battery but it only kept the radio powered up
for 5 - 10 minutes.

Would something like http://tinyurl.com/vgm4n work?
