Jump starters for diesel trucks
A diesel needs serious cranking amps. Your jump gear should too.
Updated October 5, 2026
Nothing empties a truck stop parking lot of good Samaritans faster than "can I get a jump?" at 4am in January. Carry your own solution.
Jump packs
14/20
NOCO Boost X GBX75 (14/20)
The compact NOCO for when the GB150 is more than you need. Same name, smaller punch.
Look for diesel-rated peak amps, and keep the pack itself charged — a dead jump pack is a paperweight. Store it where it won't freeze solid; lithium packs lose punch in deep cold.
Cables (the backup)
12/20
TOPDC heavy-duty jumper cables (12/20)
No-battery backup. Scored 12/20 in our power & electrical rankings.
Heavy-gauge, long enough to reach between trucks parked nose-to-tail, with clamps that actually bite. Cheap thin cables won't carry diesel cranking current.
The best jump is the one you give yourself.
Be seen while you're vulnerable
15/20
Tobfit LED road flares (4-pack) (15/20)
LED flares that don't burn out, blow out, or need a flame. Four in the pack, because one is never enough.
Jumping a truck on a shoulder at night is dangerous. LED flares set out early give traffic time to move over.
Questions, answered
Will a car jump pack start a diesel?
Usually not — diesels need far more cranking amps. Buy diesel-rated.
How do I keep the pack ready?
Charge it monthly, store it above freezing when possible.
Cables or pack?
Both. The pack is convenient; cables never run out of charge.
