Review

What to know about GOOLOO GP2000

An inexpensive 2000A lithium pack rated for engines up to 8L gas and 6L diesel, with a 400-lumen light and 24-month standby claim. TechGearLab's Best Bang for the Buck: it handled eight consecutive boosts on a 2.5L engine. It is for budget buyers with small and mid-size engines.

Editorial notes

Why it stands out

Why we like it

TechGearLab named it Best Bang for the Buck after it handled eight consecutive boosts on a 2.5L engine. It is the cheapest way here to get a pack for the glovebox.

For a typical four-cylinder car or small crossover, that performance is enough, and the low price makes it easy to keep one in each household vehicle.

What to know

Skip it if you have a large engine or diesel. TechGearLab found it struggles with big engines, and its cables and plastic are thin. Our evidence is a single lab and no measured capacity.
