-Self-jumpstarting means jumpstarting one's vehicle without the use of another vehicle.  The most common way to do this is by [[electrical:12v:alternator|combining]] house and chassis batteries.+Self-jumpstarting means jumpstarting one'own vehicle without the use of another vehicle.  The most common way to do this is by [[electrical:12v:alternator|combining]] house and chassis batteries.
  
-isolators+It will be easiest on the system to combine the batteries and allow the starter battery to come up a bit instead of immediately attempting to start.   
 +===== solenoids =====
  
 +Solenoids/relays //always// self-jumpstart assuming there is enough voltage in the starter battery to energize the solenoid. It is a mechanical connection and power will flow both ways.
  
-jump packs+===== voltage sensing relays ===== 
 + 
 +It is common for VSRs to have a button to combine the batteries for self-jumpstarting.   
 +===== relays ===== 
 + 
 +[[electrical:12v:alternator#isolators|Solid state isolators]] are diode based and will not allow power to flow from the house battery to the starter battery.  Therefore they cannot be used to self-jumpstart. 
 + 
 +===== jump packs ===== 
 +[[https://amzn.to/2ITeBba|Lithium "jump packs"]] have become more popular.  Lithium-chemistry batteries can discharge quickly, so even relative small packs can jumpstart a car.  
 + 
 +'Dwellers may want to pick a jump pack that has 12v or USB outlets so it can have other uses.
