NOCO Boost GB70 2000A Jump Starter vs AstroAI S8 Jump Starter

The NOCO GB70 is the stronger jump starter: 2000A peak, 40 starts per charge, and support for engines up to 8.0L gas and 6.0L diesel. The AstroAI S8 is smaller and lighter, with a smart boost mode for fully drained batteries, but it tops out at 6.0L gas and 3.0L diesel. Owners of both rate them well; the NOCO has the longer track record and the more rugged clamps and cables.

  • Choose the NOCO Boost GB70 if you drive a truck, SUV, or diesel and want the most starting power and starts per charge.
  • Choose the AstroAI S8 if you want a compact, light pack for a car or motorcycle and like the automatic boost mode for dead-flat batteries.

What reviewers say

NOCO Boost GB70 2000A Jump Starter

  • 4.6 / 5512 ratings

  • Size and weightCriticisedSome find the unit too bulky and heavy to keep in a small car or glovebox.
  • Battery upkeepMixedThe long hold time is praised, but owners note it still needs periodic recharging.

  • SizePraisedBuyers like that it fits in a glovebox or under a seat.

Questions and answers

Which is better for a diesel truck?
The NOCO GB70. It is rated for diesel engines up to 6.0L, while the AstroAI S8 is rated to 3.0L.
Which is easier to keep in the car?
The AstroAI S8. It weighs about 0.95 lb against 5 lb for the GB70, so it stores in a glovebox or bag more easily.
Can either start a completely dead battery?
The AstroAI S8 has a smart boost mode that unlocks a BOOST button when voltage drops below 9V. The GB70 relies on its UltraSafe clamps and does not need a separate boost step.
Which lasts longer between charges?
The GB70 is rated for up to 40 jump starts per charge and holds its charge for up to a year. AstroAI does not publish a starts-per-charge figure for the S8.
Is the GB70 worth stepping up to?
Yes if you own a large gas engine, a diesel, or several vehicles. For a small car or motorcycle, the lighter S8 covers the job.
Do both work as phone chargers?
Yes. The GB70 has a USB power bank output, and the S8 has two USB outputs at 5V 2.4A.
