Before Buying a Portable Car Battery Charger, Here are Some Things to Consider:

  • Be aware that car battery chargers are not universally applicable to all automotive batteries. Make sure you have a match before you purchase.
  • Check for a reverse polarity warning. This feature alerts users to the fact that the cables are not connected to the battery correctly.
  • Consider the recharging time. Portable car battery chargers function as second batteries in case of emergency. As a result, they should be recharged as well to ensure that the backup works and can easily jumpstart a dead car. Recharging times may vary.
  • See if a battery tester capability exists. Some car battery chargers test the charge left in an automotive battery, which can be helpful to signal time for a new battery or redirect you to a different car issue if the battery tests fine.
  • Review warranties, which can vary from model to model, and be sure that warranty length is taken into account when making a purchase decision.


Many options exist for portable battery chargers. Individuals should consider what features are necessary for their particular situations and buy accordingly. Following instructions and warnings on chargers carefully impacts performance.
