• traditional jump starter batteries are lead acid chemistries excluding most deep cycle batteries
• most 12V lithium batteries are NOT suitable for jump starting cars
• a jump starter which uses a LiFePO4 battery will be more efficient than one that uses a Li-ion or Li-Po battery
• this page outlines some options for batteries which can jump start cars as well as battery-less options

• most devices have a peak amp rating
  • in general this is not very useful as it is only the maximum current for a few secs not the 30secs you may need to crank your engine
  • however, it is likely that a device rated at 1000 peak amps will do better that one rated at a lower peak amperage
• some devices give the cold cranking amps (CCA) rating
  • this is better but perhaps not in Australia - the rating is for 30secs current at 0 °F (-18 °C)
  • a small car needs 150 CCA
  • a SUV may need 450 CCA
  • 500 CCA should start most vehicles
• a better measure is the cranking amps (CA) rating
  • this is how much current it can put out for 30 secs at 32℉ (0 °C)
  • presumably this is what manufacturers are referring to when they state starting current
  • a small - medium car with 6 cyl petrol engine or 4cl diesel engine will draw a peak current of 300 CA
  • a 4WD, especially if diesel will require at least 400 CA
  • most of the devices below provide at least 500CA which is adequate for most vehicles
• how much cranking amps do I need?
  • the larger the engine the more energy needed to turn it over
  • the older the engine the more energy you need
  • the colder the device the less it will output at zerodegC the max output may be reduced by around 35% for a lead acid jump starter
  • the colder the engine the greater the cranking amps you will need at zero deg C you may need 50% more power
• a device with greater capacity will give more jump starts

• as a minimum, these generally have:
  • a lithium polymer battery
  • LED torch with SOS mode

• these do not contain a battery but uses a super-capacitor to provide the charge
• they have the advantage of rapid charging:
  • at 12V source might charge them in under 2 minutes
  • a 12V 10A cig lighter source may charge them in 5 minutes
  • a USB source may charge them in under 1hr
  • may even be charged by a flat battery with only 3V left so they can be left uncharged in the car and used when the battery goes flat
• another advantage is they do not lose charge over time
• the disadvantage is that they can't charge or power other devices
