NOCO Boost Plus Jump Starters: 5 Best-Reviewed

Compact, powerful, and safe, NOCO Boost Plus jump starters just work.

You hit the key and hear nothing. It is late, cold, and you need to be on your way. That is exactly when a pocket-sized jump box can save the day. NOCO Boost Plus Jump Starters give you fast starts, safe cables, and handy extras like a flashlight and USB charging. I have used and tested jump packs for years, and these stand out for reliability and ease. If you want a simple, safe solution that works across cars, trucks, boats, and more, the NOCO Boost lineup is hard to beat.

NOCO Boost GB40 1000A UltraSafe Jump Starter

The NOCO Boost GB40 is the pocket jump starter I suggest to most drivers. It is a 1000-amp, 12V lithium booster rated for up to 6.0L gas and 3.0L diesel engines. It slips into a glove box, yet packs enough punch to revive a car, SUV, or small truck. NOCO’s UltraSafe tech keeps sparks down and protects against reverse polarity, which gives new users peace of mind.

In daily use, the GB40 feels solid and simple. The clamps are compact, yet they bite well on side and top posts. The unit doubles as a power bank with USB output for your phone, and the LED flashlight helps in dark engine bays. NOCO Boost Plus Jump Starters like this one shine because they combine safety, power, and portability.

Pros:

• Compact size fits glove boxes and center consoles
• 1000A peak current handles most sedans and SUVs
• UltraSafe design reduces spark risk and polarity errors
• Built-in LED flashlight with multiple modes for night use
• USB power bank charges phones and small devices
• Clear, simple status lights make it easy for beginners
• Reliable even after long storage when properly maintained

Cons:

• Short clamp leads require getting close to the battery
• Not strong enough for big V8 gas or larger diesel trucks
• No wall charger in the box; you charge via USB

My Recommendation

If you want one jump starter that fits almost any daily driver, pick the GB40. It is the sweet spot for reliability and size. It is ideal for small to midsize cars, crossovers, and even light pickups. It also makes a smart gift for new drivers. NOCO Boost Plus Jump Starters like the GB40 are easy to store, charge, and use, which means you will actually carry it.

Best for	Why
Most daily drivers	1000A peak starts 6.0L gas/3.0L diesel with room to spare
Glove-box carry	Small and light but still powerful and safe

Overall value is excellent. It saves time, towing costs, and stress, and it is easy to find in stock.

NOCO Boost GB70 2000A UltraSafe Jump Starter

The NOCO Boost GB70 steps up to 2000A peak for bigger engines. It is rated for up to 8.0L gas and 6.0L diesel, which covers full-size trucks, SUVs, and many boats. The body is larger than the GB40, but it is still portable. If you want strong cranking power without moving to a full shop booster, this is the one.

I like the extra features on the GB70. The 12V output port lets you power 12V devices in a pinch. The clamps are beefier and bite through corrosion better. As with all NOCO Boost Plus Jump Starters, the GB70 includes spark-proof protection and reverse polarity defense, which makes high-power jumps less stressful.

Pros:

• 2000A power to start larger engines, including V8 gas and 6.0L diesel
• Rugged build with hefty clamps for secure connections
• 12V DC output for powering compatible gear on the go
• Bright multi-mode LED with SOS for roadside safety
• Good cold-weather performance for tough winter starts
• Clear controls and indicators help avoid user errors
• Still portable enough to live in a truck toolbox

Cons:

• Bigger and heavier than the GB40 for glove-box carry
• Premium price compared to lower-amp units
• Like others, needs regular top-ups to stay ready

My Recommendation

Choose the GB70 if you drive a full-size truck, tow, or own a small diesel. The added amperage pays off when batteries sag in cold weather. It also suits boat owners and DIYers who want a flexible 12V power source. Among NOCO Boost Plus Jump Starters, the GB70 balances serious power with simple use.

Best for	Why
Full-size trucks and SUVs	2000A peak jumps 8.0L gas/6.0L diesel engines
Cold climates	Extra power helps crank tired batteries in winter
DIY power on the go	12V DC port runs compatible accessories

It is worth the higher cost if you need dependable, high-current starts. It is widely available and often discounted during seasonal sales.

NOCO Boost X GBX155 4250A UltraSafe Starter

The NOCO Boost X GBX155 is the heavy hitter. With 4250A peak, it is rated for up to 10.0L gas and 8.0L diesel engines. That makes it a fit for heavy-duty trucks, big SUVs, RVs, and some commercial equipment. It also uses the Boost X platform for better thermal control and USB-C fast charging.

In real use, the GBX155 inspires confidence. The clamps are the most robust in this group and clamp well to thick posts. It will feel big in hand, but it is still more portable than shop units. If you want one of the strongest NOCO Boost Plus Jump Starters money can buy, this is it.
