Traditional jump starters often rely on bulky lead-acid batteries, which are heavy, bulky, and can suffer from corrosion and shorter lifespans. The NOCO Boost GB50, by contrast, uses advanced lithium-ion battery technology, which offers several key advantages:

• Compact and lightweight: The GB50 weighs only about 2 pounds, making it easy to carry and store in a vehicle glove compartment or backpack.
• Longer lifespan: Lithium-ion batteries generally last longer and retain charge better over time than lead-acid counterparts.
• Faster charging: Using USB-C charging, the GB50 recharges quicker and more conveniently than traditional models.
• Enhanced safety: Features like spark-proof clamps and reverse polarity protection are less common on older jump starters.
• Multi-functionality: Acts as a power bank and flashlight, unlike many traditional single-use devices.

Overall, the GB50 is more user-friendly, durable, and versatile, making it a superior choice for modern drivers who want convenience and reliability.

What maintenance does the NOCO Boost GB50 require?

The NOCO Boost GB50 requires minimal maintenance, thanks to its rugged design and modern battery technology. However, to ensure optimal performance and longevity, some best practices are recommended:

• Keep it charged: Recharge the device at least every 3 to 6 months to maintain battery health, even if unused.
• Store properly: Keep the jump starter in a cool, dry place when not in use. Avoid extreme temperatures that can degrade lithium batteries.
• Inspect cables and clamps: Periodically check for wear, corrosion, or damage on the clamps and cables and clean as needed.
• Avoid water immersion: While IP65 rated for water resistance, avoid submerging or exposing it to heavy rain to protect internal electronics.
• Test regularly: Consider testing the jump starter once a year by attempting a jump start or verifying the battery charge.

Following these guidelines will ensure the GB50 is always ready to perform when needed and extends its useful lifespan for many years.

Can the NOCO Boost GB50 be used for diesel engines?

Yes, the NOCO Boost GB50 is designed to jump start diesel engines up to 4.5 liters in size. Diesel engines require higher cranking power due to their compression ratio, so having a jump starter rated for diesel engines is important if you own such vehicles.

The GB50’s 1500A peak current is sufficient for many light and mid-sized diesel trucks, vans, and boats. However, it may not be adequate for very large commercial diesel engines (above 4.5 liters), which generally require jump starters with higher amperage ratings.

If you frequently drive large diesel vehicles, it may be wise to consider a more powerful model like the NOCO Boost GB70, which offers greater jump-starting power tailored to heavy-duty diesel engines.
