Noco GB70 Review
NOCO Boost HD GB70

The NOCO Boost HD GB70 is an easy-storing unit with the looks and feels of the quality unit it is. While packed together each part has its place in one small package, that once fully charged, makes the lithium-ion jump-starter battery perform up to 40 uses while at the same time, its ultra-safe technology secures the device from polarity reverse, overheating, and even overcharging being spark and mistake proof.

Going by the size this heavy-duty jump-starter power up high-displacement gas and diesel engines matching its design for the peak-current draw of 2000amp 12-volt that jump-start diesel engines of up to the capacity of 6.0-liters as well as 8.0-liter petrol engines.

The big beast GB70 is for 12V lead-acid batteries where much smaller batteries can be worked despite its size because the vehicle will draw required current only.

For professional use, the battery clamps have strong crocodile jaws and 400 lumens LED flashlight on one end providing a handy camp-light option for times under-bonnet work requires some illumination.

The built-in LED light comes seven different modes where low, medium, and high, strobe, and SOS are also listed to ensure possible roadside danger prevention. Continuous runtime with up to 6-hours makes sure the Noco Boost HD GB70 is not dying at the time when you need it the most. But when carrying this compact and lightweight unit for safety, the GB70 will remarkably hold a full charge for over a year.

  • Compared to the weight of 2.3kg, and the size of 185mm in width, 315mm in length, and 92.5mm in height, the NOCO Boost HD GB70 jump-starter has managed to jam high technology with too much power inside.
  • The NOCO Boost HD GB70 is technically a 2000amp 12-volt jump-starter capable of jump-starting diesel engines (up to 6.0 liters) and petrol engines (up to 8.0-litre) as well.
  • Along with the usual engineered protection against polarity reverse, sparks, overheating as well as, and overcharging, GB70 has propensities for 40 jump-starts per charge while the highlighted operating range is claimed between -30°C and +50°C temperature.
  • The recharging time of NOCO Boost HD GB70 2000amp 12-volt jump-starter is between 2-3 hours from 12 volts and can also be charged through the USB.
  • The portable NOCO GB70 contains a USB port and has an included 12V plug, to provide personal electronic device charging while being rugged enough to power tire pumps, inverters, camp lighting, and chargers remotely through the 12V power outlet.
  • On top of all why questions- is light with seven modes and 400 Lumens of output production including 2 emergency-flashing modes and 1-strobe mode.


  • Lighter with carrying ease
  • Multifunctional and compatible
  • Provides consistent performance.
  • Renders 40 boosts max once charged.
  • A 2000 peak-amps charging capacity.
  • A 400-lumen system has 7 modes.

  • Could be relatively costly.
  • Device charging drains it quickly.

NOCO Boost HD GB70 Noteworthy Features

  • Ultra-secure and mistake-proof NOCO Boost GB70 is a lithium-ion jump-starter that makes boosting batteries easy for even someone with zero technical understanding.
  • Super powerful rating of 2000 amp- peak is hands down for diesel engines up to 6 liters gas engines up to 8 liters.
  • Included manual override functionality serves to boost a battery discharged down to 0-volts.
  • The 2.1A USB built-in output recharges personal electronics and 12V DC attachment power 12-Volts devices like power inverters.
  • A built-in 400-lumen ultra-illuminated 8-LED flashlight is designed with 7 light modes that include SOS and emergency strobe.
  • Compressed and lightweight power unit with easy storing ability recharges fast from zero to jump-start ready in about 15 minutes.


Q: What happens if the clamps touch together?

A: Nothing, there will be zero sparks and hence, it is completely safe. NOCO Boost HD GB70 has built-in sensors for preventing power deliverance to anything unless a battery is detected.

Q: What happens if you connect to a battery backward?

A: This is called the reverse polarity where the error LED will be illuminated only without any sparks at all. It is perfectly safe unless the battery is properly connected, GB70 will not deliver power. 

Q: How do I charge NOCO Boost HD GB70?

A: This should come with 12V cables for making use of the cigarette lighter/power port to charge it in vehicles besides a micro-USB cable for using a powered USB port for charging it. This second cable has usability with computers/laptops with USB connections, AC power adapters, car charger ports, etc. 

Q: How does the NOCO Boost GB70 work?

A: Press down the Power Button of GB70 to begin the jump-starting process after all necessary connections are made and the vehicle’s power loads are switched off. For indicating properly functioning LEDs all LEDs will flash. The White LED should illuminate to indicate a proper connection to the battery and to tell you that it is ready. If starting your vehicle does not immediately start it means the GB70 is required to be connected for a max of 30 seconds before starting. Remove the GB70 and the battery clamps once the vehicle has been started. However, only attempt up to 5 back-to-back jump-starts within a short span of 15 minutes and try again after a break of 15 minutes.

Q: Does the NOCO Boost GB70 charge battery?

A: No, Noco GB70 is a jump-starter and not a battery charger so it will not serve the purpose.

Q: Where can I purchase the NOCO Boost HD GB70?

A: We like Amazon for competitive pricing and fast delivery, although there are other good and trusted resellers and the possibly directly from the manufacturer
