I know very little about this, other than that it has 2 fuses, and 8' of power card. I got it as part of some other stuff in an auction. Calling (703-four-nine-four-1057) works best, as I do not check my email more than twice per day (some days just once). Expect to leave a message, as that is how I filter out the spam calls. And I do NOT have texting capability. If the ad is up, it is available (unless there is a PPU in the title, in which case you may still call if you want to be the backup).
