I wonder how many of you carry jump packs? Cars and Bikes. In the state partol, we had to turn in our jumper cables when a trooper jumped a car that blew out every computer in his car, including the two way radios. We got jump packs. Now, you can pay $20-60 for a jump pack that will do the job. But they dont last for ever, like your cell phone battery. And I have some that are going on 7 years old now. I check them with a simple resistive checker and if under a major load, they drop below 9 volts, I consider that marginal. But They would probably still work for a bike. Vehicles are full of complex computers and there is no way a weak battery is gonna run the computers and fuel injection system without a jump. My wife has saved 3 people so far with hers at dog shows.....with mine, Frosty and I were able to proove his truimph battery was toast by the side of the road and just went and got another one. Now I have a car where even the refueling door is controled by a computer. So I am trying out a new jump pack. I think for $50 its pretty cool. It uses a C type USB to charge it up and the plug for the jumper cables has a digital voltmeter on it. Hopefully, it will outlive me. I check and charge them twice a year.....they will power an air compessor or cell phone also. Here it is being charged for the first time with the cables plugged in.
