1. NOCO Boost HD GB70: Editor Reviewed
The NOCO Boost HD GB70 is a heavy-duty lithium jump starter rated at 2000 amps of peak power, putting it a clear tier above compact units. Based on specs and verified owner reviews, it reliably starts vehicles up to roughly 8 liters of gas or 6 liters of diesel, which covers most trucks, SUVs, and vans. That headroom is the main reason buyers step up to this model instead of a smaller starter.
Build quality is a standout, with an IP65-rated enclosure wrapped in thick rubber that shrugs off drops, dust, and moisture. The heavy-gauge clamps and cables feel substantial in the hand and match the rugged look owners consistently praise. It is noticeably bigger and heavier than a pocket unit, but that weight reflects the larger battery and tougher housing.
Beyond jump starting, the GB70 works as a 12V and 24V USB power bank for phones and tablets and includes a 400-lumen LED flashlight with seven modes including SOS and emergency strobe. Safety is handled by spark-proof connections and reverse-polarity protection, so a wrong clamp will not damage the device or the vehicle. Together these features make it a capable all-in-one emergency tool rather than a single-purpose gadget.
- 2000A peak output cranks larger V6, V8, and diesel engines that smaller units cannot handle
- Rugged IP65 housing with a thick rubber shell built to survive garage and roadside abuse
- Doubles as a 12V/24V USB power bank and a 400-lumen LED flashlight with seven light modes
- Spark-proof technology and reverse-polarity protection make clamping safe even in the dark
Pros: Enough cranking power for big gas and mid-size diesel engines; Heavy-duty construction that feels genuinely durable based on verified owner reviews; Versatile extras including USB charging and a bright emergency flashlight; Safe, beginner-friendly connection with clear clamp guidance and error feedback
Cons: Bulkier and heavier than entry-level units like the GB40; Overkill for small four-cylinder cars where a cheaper model would do
Frequently Asked Questions
Can the NOCO GB70 start a diesel engine?
Yes. The GB70 delivers 2000A of peak power and is rated for diesel engines up to about 6 liters, covering most pickups, vans, and mid-size diesels. For very large diesel engines, NOCO offers higher-capacity models like the GB150.
How many jumps can the GB70 do on one charge?
On a full charge the GB70 can deliver up to roughly 40 jump starts for typical engines before it needs recharging. Holding the charge for storage is easy, as the internal lithium battery loses very little power when left idle for months.
Is the NOCO GB70 worth it over the cheaper GB40?
It depends on your vehicle. If you drive a larger gas truck, SUV, or a diesel, the GB70 extra cranking power is well worth it. If you only need to start a small four-cylinder car, the GB40 covers that job for less money.
Our Verdict
The NOCO Boost HD GB70 earns its strong reputation by combining serious 2000A cranking power, rugged build quality, and genuinely useful extras like USB charging and a bright flashlight. Based on specs and verified owner reviews, it is one of the most capable portable jump starters you can keep in your trunk, especially for larger gas and diesel engines. If you drive a small commuter car, the lighter GB40 may be the smarter spend, so it is worth reading our NOCO GB40 vs GB70 comparison before deciding. For most truck, SUV, and diesel owners who want one tool that handles almost anything, the GB70 is an easy recommendation, and you can see how it stacks up against the field in our guide to the best jump starters.
