70mai Jump Starter - Automotive Roadside Emergency Equipment Review

70mai Jump Starter - Automotive Roadside Emergency Equipment Review
70mai Jump Starter: 600 CCA worth of 40 jump starts in compact rechargeable Lithium Ion unit

Lithium Ion battery cells might be on the electric motor propulsion rise, supplanting Nickel Cadmium. However, 6 cell 12V lead acid batteries still provides the critical voltage to fire up the internal combustion ignition and run accessories for 99% of the world's passenger vehicles, including those pesky petrol electric hybrids.

Extreme conditions take their toll on lead acid battery performance:

  • TIME - After 5 years typical passenger automotive use results in corrosion of the lead cathode plates, reducing the ability to hold charge current
  • HEAT - Ditto the effect of TIME (above)
  • COLD - Electrolyte passes current more slowly, while reduced engine lubrosity demands more electric current to crank
  • SHORT TRIPS - Sulfuric acid needed for cathode process stratifies at bottom of battery leaving upper lead plates only with water solution.

The recurrence of these extremes over time may necessitate a battery jump to start the vehicle. The traditional go-to is an available and willing running donor car with a pair of long jumper cables is one resource.  When the running donor isn't available a portable jumper is the next best bet.

Automotive accessory distributor 70mai supplied Roadblazing.com editors with their latest portable car jumper, the  70mai Jump Starter by Xiaomi Youpin.
