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 :) R -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Nash - Lists Sent: Sunday, October 29, 2006 11:53 PM To: WISPA General List Subject: Re: [WISPA] Powering 12-volt CPE via battery for site surveys 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.
