On the trip to Ballarat for the National Rally the power outlet on Streak's ST stopped working
This was an issue as we were using Streak's phone as a GPS and without power GPS apps will flatten a phone battery in no time at all
So to keep going until we could fix the power outlet we plugged the phone charger into the XP-3 jump starter and placed it in the side pocket
It kept the phone going all the next day
So it's got a few ways of saving you when out and about
Definitely a good investment
