-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'​s ​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.
