NOCO GB70 Jump Starter Genius Lithium – 2000A

The NOCO GB70 uses a lithium-ion battery that delivers 2,000 amps of starting current – enough to revive a flat battery within seconds. It handles up to 8 litres of petrol engine or 6 litres of diesel engine, covering cars, vans, boats and motorhomes. Trucks are also within reach. The patented safety technology enables spark-free connections – even with reversed polarity. Connect and start, without the hassle of sparking cables.

What sets the GB70 apart from simpler jump starters is its built-in protection. The device detects reversed polarity and prevents short circuits. The clamps are spark-free – a reassuring thought when you're working in the dark or the rain. NOCO calls this 'Genius' technology, but it essentially means you can't go wrong as a user. The manual is universal, so you can consult it in any language. The only thing you need: a battery that isn't completely dead – no jump starter can help with a fully depleted battery.

Specifications at a Glance

• Starting current: 2,000 A – peak current of 15,700 J3S for quick starts
• Battery capacity: 4,666 mAh – enough for up to 40 start attempts on a single charge
• Charge time: 420 minutes – expect 7 hours for a full charge via USB-C
• Maximum load capacity: 24,000 W – sufficient for larger diesel engines
• Waterproof: Yes – splash-proof to IP rating, not suitable for submersion

At 22.2 x 16.2 x 6.5 cm and 2,367 grams, the GB70 isn't something you slip into your pocket. It's a sturdy plastic casing that can take a knock. The 40 cm cable length is on the short side – ideal for batteries that are easily accessible, but less handy if the battery is deep in the engine bay. On the front, there's a 400-lumen LED torch with multiple modes, including SOS. That light is useful for breakdowns on the road, but it does drain the battery. The GB70 is waterproof according to the specs, making it suitable for use in the rain – though submersion isn't recommended.

The GB70 also functions as a portable power source. Via the USB output, you can charge smartphones, tablets and other devices. The 12V socket powers tyre pumps, inverters or other 12V equipment. That makes it useful on a campsite, at a job site or during a road trip. The 4,666 mAh battery isn't intended as a power bank for multiple devices – you can charge a phone, but don't expect multiple charges. The real strength lies in starting engines. NOCO claims up to 40 start attempts on a single charge, but that depends on battery condition and outside temperature. With cold engines or a nearly flat battery, you'll use more power per start attempt.

The GB70 comes without a case. That's a miss for a device of this size – you'll need to find your own storage solution. The packaging measures 260 x 200 x 130 mm and weighs 2,367 grams, so a sturdy carry case is recommended. The CE mark is visible, indicating the product meets European safety standards.
