A dead car battery is one of those problems most drivers don't think much about until it happens. Keeping a jump starter in your vehicle lets you get back on the road without having to rely on another vehicle or wait for roadside assistance. But with different models offering different levels of power and features, choosing the right one isn't always as simple as picking the one with the biggest number.
GOOLOO has several jump starters designed for different types of drivers, from compact models for everyday emergencies to more powerful options that can handle larger vehicles and provide additional features like tire inflation and portable charging.
GOOLOO A5: A Jump Starter and Air Compressor in One
The GOOLOO A5 is designed as an all-in-one roadside tool, combining a 4000A jump starter with a built-in 160 PSI air compressor. That makes it useful for more than just dealing with a dead battery. The compressor can also be used to inflate car and SUV tires, bikes and sports equipment, with preset modes and automatic shut-off.
The A5 also includes a sunlight-readable color display, USB-C fast charging and an LED emergency light. Its compact design is intended to make it easy to keep in a glovebox or other storage area in your vehicle. GOOLOO says the A5 can restart most 12V gasoline and diesel vehicles and includes SUPERSAFE protections such as spark-proof and reverse-polarity protection.
For drivers who want one device that can handle both battery and tire emergencies, the A5 takes an all-in-one approach.
GOOLOO GT4000S: Built for More Demanding Vehicles
The GT4000S takes a more performance-focused approach, with up to 4000A of peak current and enough capacity to restart 12V engines in larger vehicles, including trucks, RVs and boats. GOOLOO lists support for gasoline engines up to 12.0L and diesel engines up to 10.0L.
One of its biggest differences is its 100W two-way fast charging system. GOOLOO says the unit can fully recharge in around 1.2 hours, while a few minutes of charging can provide enough power for a jump-start. A 3.2-inch LED display provides status information, while USB-C and USB-A ports allow it to charge other devices.
If you drive a larger vehicle or simply want a jump starter with more charging capability and a rugged design, the GT4000S offers a more powerful option.
GOOLOO GP4000: A Straightforward Emergency Powerhouse
The GP4000 also delivers 4000A of peak current, but its focus is on providing strong jump-starting capability in a relatively straightforward package. GOOLOO says it can restart all gasoline engines and diesel engines up to 10.0L, and its BOOST mode is designed to help with extremely low-voltage batteries.
Beyond jump-starting, the GP4000 works as a portable power bank with USB and USB-C charging. It also has an LED flashlight with SOS and strobe modes, while its rugged, drop-resistant design is intended for use in roadside emergencies, travel, camping and workshop environments.
For someone who primarily wants a powerful jump starter with some useful extras, the GP4000 keeps things relatively simple while still offering plenty of capability.
What Should You Look For in a Jump Starter?
The first thing to look at is whether the jump starter can handle your vehicle. Peak amperage is an important specification, but you'll also want to check the manufacturer's listed engine-size limits for gasoline and diesel vehicles. If you drive a larger truck, RV or other high-displacement vehicle, choosing a model with enough capacity is especially important.
Next, you want to think about what else you want the jump starter to do. If tire inflation is something you'd like to have available in an emergency, a model with a built-in compressor such as the A5 can eliminate the need to carry a separate inflator. If charging phones, tablets or other devices matters more to you, check the available USB ports and charging speeds.
Size and storage are another thing to consider. A jump starter isn’t going to be useful sitting at home when you need it on the road, so look for something you can realistically keep in your vehicle. Features such as an LED flashlight, display and safety protections can also make the device easier to use when you're in the middle of an emergency.
Finding the Right Fit
A jump starter is ultimately about being prepared for something you hope you never have to deal with. The best fit is going to depend on your vehicle, the amount of power you need and which additional features would actually be useful to you.
Whether you want an all-in-one jump starter and air compressor, a higher-performance option for larger vehicles or a straightforward emergency power bank, GOOLOO offers several ways to approach the decision. Take a look at your vehicle and the situations you want to be prepared for, then choose the model that gives you the features and capacity that make the most sense for you.
