Kill the Jumper Cables

Waiting on the side of a freezing highway for a tow truck or a generous stranger is a brutal waste of time. The NOCO Boost Plus GB40 severs that dependency entirely. It forces 1000 amps of pure starting power directly into your engine from a box no larger than a hardcover novel. Amazon just knocked 20% off the MSRP, dropping this critical piece of automotive hardware just beneath the psychological $100 barrier.

Flaws & Benefits

• ✓ Pro: The user interface is completely foolproof. Reverse polarity protection guarantees you will not fry your vehicle's expensive ECU or throw sparks if you accidentally clamp the leads backward.
• ✓ Pro: Holds its charge for months in a cold trunk. You do not need to constantly bring it inside the house to top off the battery level.
• ✗ Con: The attached jumper cables are frustratingly short at just 23 inches, making it difficult to reach deeply recessed battery terminals or awkward remote ground posts.
• ✗ Con: It systematically fails to detect and jump completely dead batteries (under 2V). You are forced to manually engage the override safety feature, which temporarily disables the spark-proof protections to force the charge.

Buyer Consensus: Sustaining a massive 4.6 rating across over 123,000 reviews, it is universally recognized as the market standard for reliability. However, some buyers note that the protective carrying pouch included in the box is a flimsy microfiber bag, rather than a hard shell case.

Insight: NOCO heavily guards its pricing model. The GB40 rarely drops below $100 outside of major retail purge events. Securing a clean 20% discount on the gold standard of portable jump boxes is a highly calculated acquisition.

Final Diagnostic

Expert Take & Tip: The GB40 handles standard 4-cylinder and V6 engines effortlessly. However, do not attempt to use this specific model to crank a heavy-duty 6.7L diesel truck; it lacks the necessary sustained burst. Savvy Tip: If your car battery is completely flat, the unit will display a white error LED and fail to push power. Press and hold the red exclamation point button for three seconds. This bypasses the internal safety relay and forces raw current to the clamps, allowing the jump.

Frequently Asked Questions

Q: Can I leave the NOCO GB40 in my car year-round?
A: Yes. The internal lithium chemistry is highly stable. However, extreme sub-zero temperatures will temporarily reduce its peak cranking output, so bringing it inside during severe deep freezes is optimal.

Q: How do you charge the unit itself?
A: It recharges via a standard Micro-USB input. You can plug it directly into a wall adapter or your vehicle's 12V USB port while driving.

Q: Will it jump a 12V motorcycle or boat battery?
A: Absolutely. It is rated for any standard 12-volt lead-acid battery, making it highly versatile for motorcycles, ATVs, and marine applications.
