Walmart offers the Stanley FatMax 350-amp Jump Starter with Compressor
in Silver, model no. J7CSR, for $39.96
. Opt for in-store pickup
to dodge the $4.97 shipping charge. That's tied with last week's mention and $30 under the lowest price we could find for a similar 350-amp jump starter sold elsewhere. It features an output of 350 amps (with a peak output of 700 amps), 120 psi compressor, pivoting LED light, and 12 months of Priority Auto Assistance road-side service.
