Noco Boost Plus GB40 vs Hulkman Alpha 85 Jump Starter

The Hulkman Alpha 85 is the stronger jump starter on paper: 2000A peak, a 20000mAh battery, up to 60 jumps per charge and an 8.5L gas / 6.0L diesel rating. The Noco GB40 is smaller, lighter and simpler, rated for 6.0L gas and 3.0L diesel with up to 20 starts per charge. Owners of the GB40 praise how easy it is to use and store in the car, while some wish they had bought a larger model. Buy the Hulkman if you have a big engine, a diesel, or want a status display and long standby; buy the Noco if you want a light, no-fuss unit for a normal car.

  • Choose the Noco Boost Plus GB40 if you want a compact, lightweight jump starter for a standard gas car and value simple operation over a display and extra capacity.
  • Choose the Hulkman Alpha 85 if you drive a large gas engine or a diesel, or want a screen, faster recharging and many more jumps per charge.

Questions and answers

Which is better for a diesel truck?
The Hulkman Alpha 85. It is rated to 6.0L diesel, while the Noco GB40 tops out at 3.0L diesel.
Which lasts longer between charges?
The Hulkman, by a wide margin: up to 60 jumps per charge versus up to 20 for the Noco. The Hulkman also holds standby for up to 18 months.
Is the Hulkman worth stepping up to from the Noco?
Yes if you have a large engine, a diesel, or want a display and fast recharging. For a normal gas car, the lighter Noco covers the job.

The Noco GB40. It weighs about 2.95 lb and measures 4 x 3 x 3 inches, against about 4 lb for the Hulkman.
Do either have a built-in air compressor?
No. Neither the GB40 nor the Alpha 85 includes a tire inflator, so you would need a separate compressor.

Both protect against reverse polarity and sparks. The Noco adds a 100-lumen LED with strobe and SOS; the Hulkman adds an IP65 rating and a status display.
