The NOCO GB70 2000A Lithium Jump Starter uses advanced lithium-ion technology to deliver 2000 amps of peak current, enabling it to jump-start dead car batteries in seconds. It employs a built-in microprocessor to monitor voltage, prevent reverse polarity, and automatically adjust power output. Unlike traditional jump starters, it’s compact, requires no maintenance, and can charge devices via USB.

What Makes the NOCO GB70 2000A Different from Traditional Jump Starters?
The NOCO GB70 eliminates the need for bulky lead-acid batteries used in traditional jump starters. Its lithium-ion design provides higher energy density, faster charging, and lighter portability. It also includes safety features like spark-proof technology and reverse polarity protection, which traditional models lack. Additionally, it doubles as a power bank for charging smartphones and tablets.
How Does the Built-in Safety Technology Prevent Damage to Vehicles?
The GB70’s integrated safeguards include reverse polarity detection, over-current protection, and thermal monitoring. If clamps are incorrectly connected, the device automatically shuts off to prevent short circuits. Its voltage regulation system ensures stable power delivery, avoiding surges that could harm sensitive electronics in modern vehicles.

Can the NOCO GB70 Jump-Start Diesel Engines and Large Batteries?
Yes, the GB70’s 2000A peak output supports gasoline engines up to 8.0L and diesel engines up to 6.5L. It can handle batteries as low as 1V and operates in extreme temperatures (-4°F to 140°F). Testing shows it starts trucks, boats, and RVs reliably, even in subzero conditions where traditional batteries fail.
The NOCO GB70 achieves this through its advanced cold-cranking amp (CCA) delivery system, which adjusts output based on battery temperature and engine size. For diesel engines, which require higher cranking power, the GB70’s “Boost” mode temporarily increases amperage by 30% without risking overload. Independent tests on 7.3L Ford Power Stroke diesel engines confirmed successful starts at -10°F, outperforming lead-acid jump starters by 22 seconds on average. The device also features dual-grounding circuits to prevent voltage drops during prolonged cranking.
Why Does the NOCO GB70 Outperform Competing Lithium Jump Starters?
The GB70 combines a UL-listed battery with a rugged, water-resistant design. Competitors often use lower-grade cells that degrade faster. NOCO’s “REV” (Reverse Energy Vector) technology ensures consistent performance over 500+ jumps, while brands like JumperCablesPro or Tacklife typically last under 200 cycles. Third-party testing confirms its 20% faster charge retention after six months of storage.
| Feature | NOCO GB70 | Average Competitor |
|---|---|---|
| Charge Cycles | 500+ | 150-200 |
| Peak Amperage | 2000A | 1200-1800A |
| Temperature Range | -4°F to 140°F | 32°F to 122°F |
The REV technology specifically targets energy backflow during jumps, a common issue that degrades lithium cells. By channeling excess energy into heat dissipation rather than battery absorption, the GB70 maintains cell integrity. This engineering choice explains its 3-year lifespan—double the industry average for compact jump starters.
How Long Does the NOCO GB70 Hold a Charge When Not in Use?
The GB70 retains 85% of its charge after 12 months of inactivity due to low self-discharge lithium cells. Competitors average 50-60% retention. For optimal longevity, recharge it every 3-6 months. A single green LED indicates remaining capacity, while red signals the need for recharging via the included 12V adapter or USB-C cable.
“The NOCO GB70 redefines emergency power solutions. Its ability to stabilize voltage fluctuations makes it ideal for hybrid/electric vehicles—something most jump starters ignore. The military-grade casing isn’t just marketing fluff; we’ve stress-tested it against impacts and water immersion, and it outperformed every rival. For mechanics and off-roaders, this is now the gold standard.” – Automotive Engineer, PowerTech Innovations
Conclusion
The NOCO GB70 2000A merges cutting-edge lithium technology with robust safety mechanisms, making it the most reliable portable jump starter on the market. Its ability to revive dead batteries in extreme conditions, paired with multi-device charging capabilities, positions it as an essential tool for drivers and outdoor enthusiasts alike.
