Which 12V vehicles should you match this to
Before you buy, match the GP4000 to your engine. GOOLOO rates the 4000A booster for gasoline and diesel engines up to 10.0L, which covers most cars, motorcycles, pickup trucks, ATVs, snowmobiles, RVs, tractors, cargo vans and yachts.
We'd consider it a good fit if you want one pack that can sit in a trunk or garage and handle a 12V vehicle family rather than a single car. If your vehicle isn't 12V, this unit isn't the right choice.

What the booster can and cannot do
This is a starting aid, not a repair. It can force-start a car even when battery voltage is extremely low, because the BOOST button sends a stronger pulse through the smart jumper cables.
It cannot diagnose a weak alternator, recharge a dead battery, or make an unsafe vehicle safe to drive. If the car doesn't start, GOOLOO's guide points you to their Troubleshooting Guide, and the discount doesn't change that.
Starts engines, doesn't fix charging systems

The current offer also marks an all-time low of $79.96, so you're paying less than at any point we've recorded. With 8,963 reviews, the price is the main draw here.
What to confirm before you mount it
Charging the jump starter itself needs a wall charger, and none is included. Check that you already own a USB wall adapter for the USB to Type-C cable, and plan to top it up every 2-3 months if it sits idle.
The GP4000 arrives with an EVA storage case, so think about boot space or a shelf where the pack and clamps can live. The all-metal clamps need clean battery terminals to work reliably, and the pack does not include a permanent mounting bracket.
Who should choose or skip this pack
Choose the GP4000 if you want a high-output jump pack for a 12V daily driver, truck, RV or seasonal vehicle, and you value the BOOST button for batteries that read almost flat. The dual USB ports and Type-C input also make it useful for charging phones and tablets away from home.
Skip it if you need a charger for a non-12V system, a battery maintainer for long-term storage, or a built-in tire inflator. Also skip if you expect a wall charger in the box. Before you commit, confirm your engine size, your 12V vehicle and your access to a USB wall adapter.
