NOCO Boost HD GB70 2000 Amp UltraSafe Lithium Jump Starter
2000 peak amps handles the heaviest consumer vehicles—full-size diesel trucks, diesel SUVs, motorhomes, and boats—that the 1000A GB40 can't reliably start, making this the right choice for owners of large-displacement engines
NOCO's UltraSafe technology provides spark-proof clamp connections—you cannot cause a battery explosion by connecting clamps in the wrong order; the unit detects polarity and voltage before allowing current flow, making it idiot-proof
At 2.3 lbs it fits in a glovebox or center console where a 18-lb Clore JNC660 cannot go—the lithium vs. lead-acid weight difference is dramatic and the practical consequence is that the NOCO actually stays in the vehicle
USB-C PD input means you can recharge the jump starter from a laptop charger, phone brick, or car USB-C port rather than needing a wall outlet or automotive charger specifically
⚠️ Worth Knowing
Lithium batteries have reduced performance below -20°C; NOCO recommends warming the unit in your hands or the vehicle interior for a few minutes before attempting a jump start in extreme Canadian winter conditions
2000 amp lithium peak amps are not directly comparable to lead-acid peak amps—the sustained cranking performance of lithium units is shorter duration per jump, though adequate for most passenger and light commercial applications
At $199 it's considerably more than the GB40 ($149) and only necessary if you own diesel trucks (6L+) or very large gas engines (8L+); most passenger cars are well-served by the GB40
What Real Buyers Are Saying
What buyers love
“"Jumped my 6.7L diesel Cummins in -28°C after warming the unit for 5 minutes. Started on the first try. No other lithium starter I've tried worked in that cold."”

“"My motorhome has a 454 gas and the GB40 wasn't confident starting it. The GB70 cranks it immediately. Worth the extra $50 for the peace of mind."”

“"The UltraSafe is real. My teenager connected the clamps backwards and nothing happened—the unit detected the wrong polarity and refused to allow current until she corrected them."”

Common complaints
Performance reduced in extreme cold
Below -20°C to -25°C, lithium battery chemistry degrades meaningfully. Users in northern Canada and Prairies report needing to warm the unit inside their coat before use in extreme winter conditions—lead-acid performs more consistently at extreme cold.

More expensive than necessary for most cars
For a standard passenger car with a gas engine under 4L, the GB40's 1000 amps is more than sufficient. Paying an extra $50 for 2000 amps is unnecessary for most buyers who don't own trucks or diesel vehicles.

Clamp cable is short
The included clamp cables are shorter than professional-grade jump starters, which can make connecting to batteries positioned deep in engine bays of SUVs and trucks awkward without repositioning.

ClearPick Verdict
The NOCO Boost HD GB70 is the right jump starter for owners of diesel trucks, large-displacement gas trucks and SUVs, commercial vehicles, and boats. The 2000 amps and UltraSafe spark-proof connection make it the safest and most capable lithium jump starter available for heavy-duty consumer applications. Passenger car and compact SUV owners don't need this much capacity—the GB40 at $50 less is the better value for most households. Buy the GB70 if you own something with a large diesel or plan to keep one unit for a mixed fleet.
