I've used the Whistler Jump&Go Portable Jumpstart and Power Supply a couple of times. I'm getting ready to wire in a supply for a trailer harness and will probably wire in a 10GA wire with a fuse and the correct plug to hook the jumpstart up without the clamp type cables. I may make a pigtail adapter to run an extra cigarette lighter, usb, adapter, or battery tender for when I'm not needing the jumpstart port... I'll leave it capped in the storage compartment under the seat when not in use. Any thoughts?
