Our review
The NOCO Boost HD GB70 is a 2,000-amp lithium jump starter NOCO rates for gas engines up to 8 liters and diesels up to 6 liters, with a 56 Wh battery, a 400-lumen flashlight, a 12-volt output and an IP65 rating at 4.18 lb. This researched review reads NOCO's product and spec pages, says which vehicles need this much pack, and covers its limits.
What NOCO lists
NOCO's page describes the GB70 as a portable lithium-ion jump starter delivering 2,000 amps, designed for gas engines up to 8 liters and diesel engines up to 6 liters in cars, SUVs, trucks, boats and RVs. The spec page lists 2,000 A peak, a 56 Wh lithium-ion internal battery, a USB-C input at 5 V and 2.1 A, a weight of 4.18 lb (1.9 kg), an IP65 rating and a 1-year hassle-free limited warranty. The box includes a USB-C to USB-C cable and a microfiber storage bag.
Like the smaller GB40 it is for 12-volt lead-acid batteries only, which covers nearly every truck, SUV and boat but not 12-volt lithium batteries or EV traction packs.
Why a bigger pack
Peak amps are what turn a cold, big-displacement engine over. A 6-liter diesel pickup on a January morning asks far more of a jump pack than a sedan does, and NOCO's engine limits for the GB40 stop at 3 liters of diesel. The GB70's 2,000 A and 56 Wh cell give it the current and the reserve to try more than once; the extra pound and a half is the price.
NOCO's page also notes a 12-volt output for devices such as tire inflators and power inverters, and says the USB output gives up to six smartphone recharges. That makes it a more useful piece of roadside kit than the GB40 for a truck that tows or goes off pavement, and a fair companion to a tire inflator.
Safety and the IP65 shell
NOCO says the GB70 is spark-proof with reverse polarity protection through its mistake-proof design, so reversed clamps do nothing. The spec page's IP65 rating means the sealed, rubberized case shrugs off dust and water jets with the port covers closed; NOCO describes it as sealed against water, dust and impact, with an over-molded casing to avoid marring surfaces.
A lithium pack still needs care: keep it charged (NOCO's 2.1 A USB-C input makes a full charge a slow affair, so do it overnight), keep it out of a baking cab in summer, and read our lithium battery fire safety guide for storage. NOCO's spec page does not state an operating temperature range in text we could verify.
The 400-lumen light
The built-in LED flashlight is rated at 400 lumens with seven modes including SOS and an emergency strobe. On the side of a road at night that is enough to see under a hood and to be seen, which matters more than it sounds; it belongs in the winter car emergency kit with the flares or triangles.
How it compares, and who should skip it
The NOCO Boost Plus GB40 is half the current, half the engine range, 2.45 lb and quicker to recharge; for a car or small pickup it is the better fit and easier to live with in a glovebox. Our jump starter comparison puts them side by side.
Skip the GB70 if a compact car is all you drive: the GB40 is plenty and lighter. Skip it too if your vehicle's battery is lithium rather than lead-acid, or if you want a true power bank; 56 Wh is a few phone charges, not a day's power.
