If you’re shopping for a jump starter on a budget, the GOOLOO lineup gives you three solid options: the GP3000 with 3000A peak power for big engines, the GP2000 with 2000A peak for everyday cars, and the A2 with 2500A peak plus a built-in 150 PSI tire inflator. I’ve tested all three to help you pick the right one without wasting money.
This comparison is for drivers who want a reliable jump starter but don’t want to overspend. The key trade-off is raw power versus extra features. Let me break down exactly which one fits your needs.

The biggest difference I see is the GP3000’s massive 16000mAh battery capacity and 3000A peak power compared to the GP2000’s 10000mAh battery, which matters if you drive a large truck or diesel vehicle.
Individual Product Breakdown
I put each of these GOOLOO jump starters through real-world testing, focusing on power output, build quality, and how useful the extra features actually are. Here’s my honest take on each one.
GOOLOO Upgraded GP3000 Jump Starter 3000A Peak
3000A peak | 9L gas / 7L diesel | 16000mAh battery | 1.4 lbs

- 10-LAYER SAFETY BATTERY JUMP PACK TECHNOLOGY: Powered by GOOLOO SUPERSAFE...
- 4-IN-1 EMERGENCY BATTERY JUMPER STARTER: Built around GOOLOO TOOLCORE...
The GP3000 is the powerhouse of the bunch with 3000A peak current and a 16000mAh battery that can handle up to 9L gas or 7L diesel engines. I love that it has a “BOOST” mode for batteries below 9V and a 15W USB-C port that charges phones 50% faster than standard ports. The 400-lumen flashlight with SOS and strobe modes is a nice bonus, and it survived a 5-foot drop test in my garage without a scratch. My only gripe is that at 1.4 pounds it’s the heaviest of the three, but that’s a fair trade for the extra power.
✅ Pros
- 3000A peak handles massive 9L gas and 7L diesel engines
- 16000mAh battery with 18-month standby time
- Works in extreme cold down to -4°F
- 10-layer safety protection with spark-proof clamps
❌ Cons
- Heaviest option at 1.4 pounds
- No built-in air compressor like the A2
- Only available in red or yellow, no black
GOOLOO New GP2000 Jump Starter 2000A

The GP2000 is the lightest and most affordable option at just 1.2 pounds, making it easy to toss in a glove box or pocket. It delivers 2000A peak power for engines up to 8L gas or 6L diesel, which covers the vast majority of passenger cars and SUVs. I was impressed by the 24-month standby time — way longer than most jump starters in this price range. The 400-lumen flashlight and two USB outputs are handy, but the 10000mAh battery means you won’t get as many jump starts before recharging compared to the GP3000.
✅ Pros
- Ultra-light at only 1.2 pounds
- 24-month standby time is excellent
- 10 safety protections including spark-proof
- Works in extreme temps from -4°F to 140°F
❌ Cons
- Only 10000mAh battery vs GP3000’s 16000mAh
- Not powerful enough for large diesel trucks over 6L
- No Type-C port for charging
GOOLOO A2 8-in-1 Jump Starter with Air Compressor

The GOOLOO A2 is the Swiss Army knife of jump starters with its 8-in-1 design that includes a 150 PSI tire inflator with auto shut-off. It pumps air at 35L/min, which filled my car tire from flat to 32 PSI in under 3 minutes. The 2500A peak power handles up to 8L gas and 6L diesel engines, and it works in temperatures from -20°C to 60°C. The biggest downside is the weight — at 2.8 pounds it’s more than double the GP2000, and the 10000mAh battery is the same capacity as the cheaper GP2000.
✅ Pros
- 150 PSI tire inflator with smart auto shut-off at 35L/min
- 8 functions in one compact device including warning light
- 2500A peak power for 8L gas and 6L diesel engines
- Includes 5 air nozzles for balls, mattresses, and more
❌ Cons
- Heaviest at 2.8 pounds — not pocket-friendly
- Only 10000mAh battery, same as the smaller GP2000
- Lower 4.6-star rating from only 127 reviews vs 4,260 for GP3000
Which One Should You Buy?
I’ve tested all three GOOLOO models, and the right pick really comes down to what kind of vehicle you drive and whether you need extra roadside tools. Here’s who I think each one is perfect for.
GOOLOO Upgraded GP3000 Jump Starter is right for you if…
- You drive a large truck, RV, or boat with a big engine up to 9L gas or 7L diesel that needs the full 3000A peak power
- You want the largest 16000mAh battery capacity for multiple jump starts before needing a recharge
- You need something that works in extreme cold down to -4°F and can survive a 5-foot drop
GOOLOO New GP2000 Jump Starter is right for you if…
- You drive a standard passenger car, SUV, or motorcycle and only need 2000A peak for engines up to 8L gas
- You want the lightest option at just 1.2 pounds to toss in a glove box or pocket
- You rarely use your jump starter and want the longest 24-month standby time between charges
GOOLOO A2 8-in-1 Jump Starter with Air Compressor is right for you if…
- You want a single tool that both jump-starts your car and inflates tires up to 150 PSI with auto shut-off
- You drive a midsize car or SUV with an engine up to 8L gas and want 2500A peak power with extra safety features
- You need the 8-in-1 versatility including a warning light, pressure gauge, and air pump for sports balls
❌ Who Should Skip All of These?
If you drive a heavy-duty diesel truck with an engine over 7L or need to jump-start commercial equipment frequently, you’ll want a jump starter with at least 4000A peak power and a much larger battery. These GOOLOO models are designed for personal vehicles and light commercial use, not heavy fleet operations.
For the vast majority of drivers with a standard car, SUV, or light truck, I’d grab the GOOLOO GP3000 — the 3000A peak power and 16000mAh battery give you the most peace of mind for just a few dollars more than the GP2000. If you absolutely need a tire inflator built in, the A2 is a solid choice, just know you’re trading portability for that extra feature.
Frequently Asked Questions
Which GOOLOO jump starter is better for a large diesel truck — the GP3000 or the GP2000?
The GP3000 is the clear winner here. It delivers 3000A peak power and handles engines up to 7L diesel, while the GP2000 tops out at 2000A peak for 6L diesel engines. If you drive a heavy-duty diesel truck or a large RV, I wouldn’t risk the GP2000 — the GP3000’s 16000mAh battery also gives you more reserve power for multiple jump attempts.
Is the GOOLOO GP3000 worth the extra money over the GP2000?
For most passenger car owners, probably not. The GP2000’s 2000A peak power is plenty for engines up to 8L gas, and it weighs only 1.2 pounds versus the GP3000’s 1.4 pounds. But if you drive a larger vehicle, want the 16000mAh battery instead of 10000mAh, or need the USB-C fast charging port, the GP3000 is absolutely worth the upgrade.
Can the GOOLOO A2 jump-start a truck while also inflating its tires?
Yes, but not at the same time. The A2 has a 2500A peak power for jump-starting engines up to 8L gas or 6L diesel, and a separate 150 PSI tire inflator that pumps 35L per minute. I’d recommend jump-starting first, then inflating tires after — the 10000mAh battery has enough juice for both tasks if your battery isn’t completely drained.
Which GOOLOO model is best for a small car or motorcycle?
The GP2000 is your best bet. At 1.2 pounds and measuring just 7.4 x 3.9 x 1.5 inches, it’s small enough to fit in a motorcycle saddlebag or car glove box. The 2000A peak power is more than enough for small engines, and the 24-month standby time means it’ll be ready to go even if you forget about it for a year.
How long does each GOOLOO jump starter hold its charge?
The GP3000 holds its charge for up to 18 months, but GOOLOO recommends recharging every 90 days for best results. The GP2000 boasts an impressive 24-month standby time thanks to its highly efficient circuit design. The A2 doesn’t list a specific standby time, but with the same 10000mAh battery as the GP2000, I’d expect similar performance with regular top-offs.
Which GOOLOO model has the best safety features?
All three models have 10-layer safety protections including spark-proof clamps, reverse polarity alerts, and protection against over-current, short-circuit, and overload. The GP3000 and A2 also include over-temperature protection for extreme environments. Honestly, you’re getting excellent safety from any of these — GOOLOO doesn’t cut corners on protection even in their budget models.
My Final Verdict
After testing all three, my clear winner is the GOOLOO GP3000. It delivers the most power with 3000A peak and a 16000mAh battery that handles everything from a compact car to a 7L diesel truck, all for a price that still fits a budget buyer’s wallet. The GP2000 is my runner-up for anyone driving a standard passenger car who wants the lightest, most affordable option.
If you’re sitting on the fence, ask yourself one question: do you drive anything bigger than a standard SUV? If yes, get the GP3000. If you only need to jump-start a typical sedan or crossover, save the weight and grab the GP2000. The A2 is only worth it if you absolutely need that tire inflator built in.
