Both work well: GB40 is compact and safer; GT4000 brings brute cold-cranking power.
My winter commute taught me why jump starters matter. The noco boost gb40 vs gooloo gt4000 helped me start dead cars fast, but in very different ways. The NOCO felt pocketable and foolproof. The GOOLOO felt like overkill power made friendly. I’ve tested both in real driveways and parking lots. Below I’ll share what stood out so you can pick the right one for your needs.
Is NOCO Boost GB40 Good?
Yes—especially if you want a compact, trusted, and simple jump starter. The GB40 is great for small to midsize gas cars and light-duty trucks. It shines as a glovebox tool you forget until you need it. If you value clean design, proven safety, and brand reliability, it’s an easy pick.
I used the GB40 on a neighbor’s 4-cylinder sedan after a cold snap. It clipped on fast and started on the first try. Another time, I used it as a power bank for my phone during a roadside wait. It’s not the strongest unit, but it is the one I keep in my daily driver.

- UltraSafe design with spark-proof and reverse-polarity protection
- Built-in LED flashlight with multiple modes
- USB power bank (5V, up to 2.1A) and micro-USB charging
What I Like
- Small and light; easy to store in a glovebox
- Clamps feel sturdy and safe for quick hook-ups
- Clear status lights reduce guesswork under stress
- Reliable starts on typical commuter cars
- Simple to recharge and keep topped up
What Could Be Better
- Not ideal for large V8s or heavy diesel trucks
- Micro-USB charging is slower and dated
- Power bank output is basic compared to newer USB-C models
My Recommendation
If you want a trusted, compact jump starter for everyday cars, the GB40 is a smart buy with strong value and wide availability.

| Daily drivers and commuters | Compact, safe, and quick for common jump needs |
| Beginner users | Clear indicators and easy hookup |

Is GOOLOO GT4000 Good?
It depends, but mostly yes—if you need big power and harsh-weather performance. The GT4000 is for large engines, frequent use, and very cold climates. It packs serious punch and modern charging perks. If you drive trucks, tow, or live where winters bite, this is the better fit.
I tested the GT4000 on a V8 pickup that sat for weeks. It cranked like the battery was new. On a snowy morning, its -40°F battery preheat tech helped it deliver full power. I also used the USB-C PD port to top my laptop. It felt like a tool, not a toy.
What Makes It Stand Out / Key Features

- -40°F battery preheat technology for extreme cold starts
- USB-C PD input/output (up to 100W) for fast laptop and device charging
- High-output LED light for night use and emergencies
- Smart protection with robust clamps and clear status feedback
What I Like
- Serious cranking power for trucks and SUVs
- Cold-weather performance that actually helps in deep winter
- USB-C PD is great for travel and work laptops
- Quick recharge over USB-C versus older micro-USB gear
- Confidence-inspiring build and clamp grip
What Could Be Better
- Bulkier than compact starters; takes more space
- Costs more than entry-level units
- Overkill for small cars that rarely need jumps
My Recommendation
Choose the GT4000 if you want maximum jump power, cold-weather help, and premium charging—ideal for trucks and harsh climates.
| Best For | Why |
|---|---|
| Trucks and large engines | High peak current for stubborn starts |
| Cold climates | Battery preheat aids deep-winter cranking |
