This button forces voltage to be present from YESPER even when no voltage detected from target. The normal safety protocol requires target voltage to be detected before YESPER will supply voltage itself this safety is YESPER proving correct cable hookup. In my nobattery present jump the Vehicle started right up and remained running. Obviously, target vehicle died the instant I removed YESPER and I did not let YESPER stay connected but a few seconds. The point of here is to say yes, it will start when a vehicle with a totally dead battery. **Q: Can transport it abroad?** A: Dear Customer: Which country are you from?

Got one from amazon works great. **Q: If after hooking this up and cranking the starter it does not start what steps need to take place to try and start it again?** A: Ok...when you read the little booklet it will tell you...there is a little button near the blinking green light you press to fully energize...that should get you your solid green light. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Appears as advertised *by D***Y on January 9, 2026* Came 82% charged, charged overnight, haven't had to use yet; seems as advertised. ### ⭐⭐⭐⭐⭐ Must have *by U***- on November 27, 2024* Great item to have in your car for back up.
