NOCO Boost HD GB70 2000A 12V Lithium Jump Starter Review (2026)

Who the GB70 is built for

The NOCO Boost HD GB70 is aimed at owners of trucks, SUVs, tow vehicles and other larger engines that smaller lithium jump starters are not rated to handle. NOCO rates it at 2000 amps, enough for gas engines up to 8.0 liters and diesel engines up to 6.0 liters, covering full-size pickups, work trucks and larger camping tow rigs that a compact car-focused jump pack would struggle to start reliably. That heavy-duty rating is the whole reason to choose the GB70 over one of NOCO's smaller Boost models, so buyers with a compact car or small SUV are better served by a lighter, cheaper pack sized to their actual engine rather than paying for capacity they will not use.

Power, safety and included flashlight

Under the hood, the GB70 uses high-discharge lithium technology rated for up to 40 jump starts on a single charge, backed by NOCO's patented spark-proof and reverse polarity protected clamps that guard against a wrong connection at the battery. NOCO builds the unit with a water-resistant IP65 enclosure and rugged rubberized housing, reflecting its positioning as gear meant to live in a truck bed or tool box rather than a glovebox. Beyond jump starting, it doubles as a power bank capable of multiple phone recharges, and includes a built-in 400 lumen LED flashlight with seven light modes, useful for working on a vehicle or lighting a campsite after dark without a separate light.

Using it and keeping it charged

At 5.0 pounds, the GB70 is noticeably heavier than NOCO's compact Boost Plus or Boost X models, a direct trade-off for its higher amp rating and larger internal battery. NOCO states the unit holds its charge for up to a year in storage, which matters for gear that might sit in a truck for months between uses, and it recharges in a few hours when it does need a top-up. A 12-volt auxiliary port lets it power accessories like a tire inflator or small inverter beyond just starting an engine, which adds some versatility for campers who want one device to cover jump starts, device charging and basic 12-volt power in one unit.

How it compares with other NOCO jump starters

Against the NOCO Boost X GBX155, which our data ranks close behind and offers a higher 4250 amp rating for even larger diesel engines, the GB70 sits in the middle of NOCO's heavy-duty lineup rather than at the top, making it the right choice for large gas trucks and mid-size diesels without paying for capacity meant for the biggest commercial engines. Compared with the smaller NOCO Boost Plus GB40, rated at 1000 amps for smaller car and motorcycle engines, the GB70 is a clear step up in both weight and capability, so the right choice between them comes down to matching the pack's rating to the actual vehicle being started rather than simply buying the highest number available.

Verdict and who should size differently

For anyone regularly starting a full-size truck, tow vehicle or diesel engine, the NOCO Boost HD GB70 earns our score of 8.4 out of 10 by combining a genuinely heavy-duty amp rating with NOCO's proven safety features and a useful built-in flashlight. It is a strong, purpose-built pick for that use case. Owners of compact cars, motorcycles or small SUVs will find the GB70 heavier and pricier than they need, and should instead choose one of NOCO's smaller Boost Plus or Boost packs sized to a smaller engine, saving the GB70's extra capacity and weight for vehicles that actually require it.
