GOOLOO GP4000 4000A Peak Lithium Jump Starter
High-output 4000A 12V lithium jump starter with USB-C and Quick Charge power-bank ports.
Quick verdict
The high-power-for-the-money pick — 4000A covers essentially all gas engines and up to 10L diesel at a price well under premium-brand heavy-duty units; a consistent reviewer value favorite.
Who it's for
Truck/diesel owners and value hunters who want the most cranking amps per dollar.
Key features
- 4000A peak
- all gas
- up to 10.0L diesel
What to know before you buy
- GOOLOO's amp ratings run higher/less conservative than NOCO's, so don't compare 4000A one-to-one. Reputable and well-reviewed, less premium finish.
