Buying Guide
Peak Current and Engine Compatibility
The most critical factor is how much peak current the jump starter can deliver. This determines which engines it can reliably start. NOCO offers a wide range from 500 amps on the GB20 up to 4250 amps on the GBX155. Hulkman models typically start around 1000 amps and go up to 3000 amps. For a standard four-cylinder car, 1000 amps is plenty. For a large V8 or diesel truck, you need at least 2000 amps. Always match the unit to your vehicle’s engine size for dependable performance.
Safety Features
Jump starting a battery involves high current, so safety is non-negotiable. NOCO is famous for its UltraSafe technology, which includes spark-proof circuitry and reverse polarity protection. Hulkman also includes similar safeguards, but NOCO’s patented design is widely recognized as the gold standard. Both brands prevent dangerous sparks and protect against incorrect clamp connections.

Portability and Build Quality
If you plan to keep the jump starter in your glove box or emergency kit, size and weight matter. NOCO units are compact and lightweight, with the GB20 weighing only 2.4 pounds. Hulkman models are also portable but tend to be slightly heavier due to larger battery cells. Both brands use rugged, impact-resistant housings. NOCO’s IP65 rating on many models adds dust and water resistance, making them more durable in harsh conditions.
Additional Features
Modern jump starters double as power banks and flashlights. NOCO units include integrated LED flashlights with multiple modes, including SOS and strobe. Hulkman models often feature USB ports for charging devices and some include digital displays. NOCO’s GBX series supports USB-C Power Delivery for fast recharging, which is a major convenience.

Whichever you pick, you get a reliable tool that will keep you moving.
Frequently Asked Questions
Can I use a NOCO jump starter on a diesel engine?
Yes, but you need a model with enough peak current. For diesel engines up to 3.0 liters, the GB40 works. For larger diesels up to 8.0 liters, choose the GBX155 or GB70. Always check the engine size rating before purchasing.
How long does a NOCO jump starter hold a charge?
NOCO lithium jump starters can hold a charge for up to 12 months when stored properly. We recommend recharging them every six months to ensure peak performance. The GBX series can recharge from dead in under three hours via USB-C Power Delivery.
Are NOCO jump starters safe for modern vehicles?
Absolutely. NOCO’s UltraSafe technology is spark-proof and includes reverse polarity protection, making them safe for all 12V vehicles including modern cars with sensitive electronics. They will not damage your vehicle’s computer or electrical system.
What is the difference between NOCO GB and GBX series?
The GBX series is NOCO’s extreme performance line, offering higher peak currents, faster recharging via USB-C Power Delivery, and a 60-second timer for energy conservation. GB models are more affordable and still very capable for everyday use. For a full breakdown, visit our NOCO jump starter guide.
