Do not use a power inverter!

[Bill@HPTuners]

It is NOT recommended to use a power inverter with our product as some of the cheaper inverters can create an overcurrent issue which can potentially fry your interface beyond repair.

I will try to list the worst offenders here as we find them but just consider them all off limits.

We recommend you using a FULLY charge laptop for scanning, editing & flashing to avoid risking your expensive interface as repairs for damage caused by an inverter is NOT covered under our warranty.

Thanks,

I fried the serial port on my IBM laptop through the
old style interface, using an inverter. The interface
worked afterward but the laptop port did not. The
problem came about when I was working on a truck
that had a very low idle system voltage - the inverter
began to "flicker" in and out of undervoltage cutout
and bounced the ground hard enough to hose the
hardware.

The one in question was "Vector" brand, one of the
kind you plug into the cig lighter. 75W I think.

I have since used the same one in my car numerous
times without issue, because my system voltage is
13V+ (truck was barely holding 10V). Serial and USB.
But I use battery when I can, just from the experience.

I think I'm well out of warranty. If you are covered,
take the advice.
