Will the Alpha 85 start my diesel truck?

It is rated for diesel engines up to 6.0L and gas engines up to 8.5L at 2000A peak. Larger engines may need a higher-output unit.

How long does it take to charge?

Hulkman rates 0% to 80% in about one hour and a full charge in roughly 90 minutes. A standard USB charger works for topping it up.

How many jumps do I get per charge?

Up to 60 jump starts per charge, depending on engine size and temperature. Big diesel engines will use more power per start.

Can I leave it in the car for months?

Hulkman claims up to 18 months of standby, and the IP65 rating handles dust and spray. Check the display every few months and recharge before winter.

At $119.99 at Amazon as of November 8, 2026, it is priced for a high-output pack with fast charging and a display. Buyers with small cars may do fine with a cheaper, lighter unit.

Does it work on 24V systems?

No. It is a 12V jump starter, so it suits cars, trucks and boats with 12V batteries, not 24V setups.
