Well, being a supportive member, had I known Pashnit had them I would have gottin it from him.
The "cheaper" units do not come with the fuse holder and do not produce enough voltage for the I-anyting. Nor do they come with the weather proof "boot" to cover the USB plug in case of bad weather. Nor can you easily find a short cable with a right angle tip.
Didnt think that would matter until it keeps getting hung up when I turn. Argggg.
The cost difference:
If you add your own fuse holder it comes out to about what Pashnit is selling them for. Any other members selling them Im not sure. I also noted that the "attachement" clip/mount that comes with the cheaper
unit doesnt have much to mount with. Pashnit's unit has a slightly different way it wraps around the plug, and then can be mounted, thus giving more options. All in all, the cheaper one works fine. I have two, one on the left and one on the right of the ignition key. I have a sig lighter with a battery tender plug in the trunk. Plugs into the battery tender cable when im riding. Good for on board compressor, phone, etc if needed. I put fuses on all connections fyi. Savings with cheaper model, and I dont use and I phone etc, about the same cost minus the rubber boot covering and the right angle cables. Get what you pay for.
Just my observation 2 cents.
