How-to

How often should you recharge a jump starter?

Lithium jump packs slowly self-discharge. A pack that sat for a year may show LEDs yet still fail under load. Build a simple recharge habit.

Simple schedule

  • After every jump attempt — recharge soon
  • Every 2–3 months in storage (or per your manual’s standby claim)
  • Before winter and before long road trips
  • After using USB ports as a power bank

Fast-charge models

GT-series packs with bidirectional USB-C can return to ready much faster than micro-USB trickle charge. That matters if you jump and then drive away the same day.
