AstroAI S8 Jump Starter vs Gooloo GT6000 Jump Starter

The Gooloo GT6000 is the stronger jump starter: 6000A peak, up to 12.0L diesel, a 3.2-inch display, IP65 water resistance and roughly 1.4-hour recharge. The AstroAI S8 is the smaller, lighter pack for cars, motorcycles and lawnmowers, with 1500A peak and 6.0L gas/3.0L diesel coverage. Owners rate the S8 highly and call it easy to store; the GT6000 is the one to step up to for trucks, RVs and repeated starts.

  • Choose the AstroAI S8 if you drive a car, SUV or motorcycle and want a compact pack that fits in a glovebox or travel bag.
  • Choose the Gooloo GT6000 if you need to start large diesel trucks, RVs or ATVs, or want a power bank that can charge a laptop.

What reviewers say

  • SizePraisedBuyers like that it fits in a glovebox or under a seat.
  • Battery reserveCriticisedSome owners find it needs recharging after only a few jump starts.
  • ClampsCriticisedThe jumper clamps and cables are described as short and stiff in cold weather.

Gooloo GT6000 Jump Starter

Owner feedback on the GT6000 centers on its starting power for large engines and its fast recharge. Some find it heavier and pricier than a basic jump pack needs to be.

Questions and answers

Which is better for a diesel truck?
The Gooloo GT6000. Its 6000A peak and 12.0L diesel rating cover heavy engines that the S8's 1500A and 3.0L diesel limit cannot.
Which is easier to keep in the car?
The AstroAI S8. It weighs about 1.1 kg and is small enough for a glovebox, while the GT6000 is a larger pack better suited to a trunk.
Can either charge a laptop?
Only the GT6000. Its USB-C port delivers up to 100W, enough for many laptops. The S8's USB ports are 5V/2.4A phone charging.
Which lasts longer between charges?
The GT6000, with a 27,000mAh battery and up to 24 months of standby. The S8 has a 37Wh battery and is meant for occasional starts.
Is the GT6000 worth stepping up to?
Yes if you own a truck, RV or ATV, or want fast recharging and a screen. For a sedan or motorcycle, the S8 covers the job in a smaller package.
Do both have safety protections?
Yes. The S8 lists eight protections, including reverse polarity and short circuit. The GT6000 uses a 10-layer safety system.
