Most small engine shops carry either a screw on terminal or a crimp on type. The latter has a boot that slips over the terminal. A couple of bucks should get you back in business.

If you have the spark plug terminal off the plug and pulled away so it doesn't make contact with the spark plug - it won't try and run. If you wish to ground the terminal - any piece of conductive wire attached to the terminal and the other end to the chassis of the mower .Tip the mower w/ the air filter up as to not contaminate the filter w/ fuel.

If the top of the head and spark plug get hot enough to ignite wood a fire is going to be the least of your engine problems. Mike

All you want is to not have to use the apple wall plug and still have fast charging? Your question could be clearer. Your best bet is as above stated...buy it. If you want to mod the cable thats a little different. I was looking into making a hub useable for fast charging and data transfer at the same time. I found it to be complicated by apple. They add ressistors to there plug lines to disallow fast charging from some devices. The resistor can vary from iphone models. I was looking at the time the 4 was the thing so maybe things have changed. There was a company that would sell the mod parts but I forget the name. For some reason I think they could not sell completed units... legalese crap. In the end I never made the time to do the mod. Just use the wall plugs. You make me wonder if fast charging will work in the hard wired wall usb outlets I bought... never though to check. I never had an issue other than hubs. You may be better served asking at a place like XDAdevelopers.
