Together, these functions make the GB70 more than just a jump starter; it’s a compact emergency power tool that supports a range of practical needs for drivers who want a well-rounded roadside or workshop companion.
Safety & Protection Features
The NOCO Boost GB70 is engineered with multiple safety systems that make it accessible and reassuring for drivers of all experience levels. At its core is NOCO’s UltraSafe protection technology, which helps prevent sparks and instantly alerts you if the clamps are connected with reverse polarity — a common user error that can damage vehicle electronics or the jump starter itself. Beyond polarity protection, the GB70 also incorporates safeguards against over-current, over-voltage, and over-temperature, so it only delivers power when conditions are safe.
These protections work together to reduce risk during real-world use, especially in roadside or low-light scenarios where stress and haste can lead to mistakes. Visual indicator lights provide clear feedback on connection status and readiness, removing guesswork and helping users confirm proper hookup before attempting a jump. With these integrated safety systems, the GB70 isn’t just powerful — it’s smart about how and when it delivers that power, enhancing confidence for both first-time users and seasoned drivers alike.
Battery Life & Running Costs
Because the NOCO Boost GB70 uses a high-capacity 12V lithium (Li-ion) battery, it delivers strong cranking power without the bulk and maintenance of traditional lead-acid jump boxes. One of the advantages of modern lithium chemistry is low self-discharge, meaning the GB70 can hold its charge for extended periods when stored properly. For best readiness, NOCO recommends recharging every 3–6 months if the unit remains unused, which helps maintain optimal battery health and ensures it’s ready when you need it.
In terms of running costs, the GB70 requires minimal ongoing expense. There are no consumables like fluid, replacement cells, or wear parts to routinely service, and the only regular maintenance is keeping the internal battery charged and inspecting cables and clamps for wear. The occasional electricity used to recharge the unit after jump starting is negligible. Over the life of the device, maintenance and operating costs are low and predictable, making the GB70 an economical investment for drivers who want a dependable jump starter without recurring service costs.
Comparison With NOCO Boost GB40
If you’re shopping in the “2000A class,” the NOCO Boost GB70 is mainly about higher starting power and broader engine coverage than smaller jump packs, while still keeping NOCO’s safety-first approach. The two most useful comparisons are against NOCO’s own GB40 and against other 2000A jump starters that compete on price and peak amps.
NOCO Boost GB70 vs GB40
Power difference: The GB70 delivers 2000A peak current, while the GB40 is 1000A, so the GB70 is better for harder starts, larger batteries, and bigger engines—especially diesel up to 6.0L and gas up to 8.0L. The GB40 is excellent for normal cars and smaller SUVs, but it has less headroom when the battery is deeply drained or the engine is larger.
Size and portability: The GB40 is more compact and lighter, making it easier to keep in a glove box or tight storage. The GB70 is still portable, but it’s larger and heavier because it’s built for higher output and more demanding jump starts.
