Detailed overview: NOCO Boost GB70 2000A jump starter
The NOCO Boost GB70 is one of the beefier lithium 12V jump starters in the NOCO lineup, with a peak current of 2000 amps. Where the GB40 (1000A) targets commuter cars and sedans, the GB70 is built for big engines: gas up to 8.0 liters and diesel up to 6.0 liters. It restarts a dead battery with no other vehicle involved, in seconds.
Its main strength is safety. UltraSafe technology protects against reverse polarity and sparks: as long as the clamps are not connected correctly, the unit will not deliver current. That is a valuable safety net, especially for anyone who is not used to handling jumper cables.
Its 56 Wh internal battery allows up to 40 jump starts per charge and doubles as a USB power bank, handy for topping off a smartphone or tablet on the road. The GB70 recharges over USB-C. It also carries a 400 lumen LED light with several modes (including SOS and strobe), useful for working after dark.
For toughness, the housing is IP65 rated (resistant to dust and water spray) and built to last. At around 2.3 kg, it stays portable enough for a trunk or a bag. Versatile, the GB70 suits cars, SUVs, trucks, RVs, and boats, and stands out as a go-to pick for anyone who wants a reliable, safe standalone jump starter capable of handling big engines.

Our tester's review: Gilles Caron
The NOCO GB70 is the kind of accessory you toss in the trunk hoping you never need it, and that becomes a lifesaver the day the battery finally gives out. We tested it on a 2.2L diesel in cold weather with a fully dead battery: clamps connected the right colors to the right terminals, green light, and the engine fired on the first crank. The 2000 amp margin is reassuring, you can tell it has headroom to spare even on a big block. What we appreciate most is the UltraSafe protection: reverse-polarity and spark protection takes all the stress out of connecting, even for someone who does not do this often. The build is tough, the IP65 housing shrugs off garage dust and damp, and the 400 lumen light genuinely helps at night on the shoulder of the road. As a nice bonus, it works as a USB power bank to top off a phone. The only downsides: it is a bit heavy at around 2.3 kg, and a full recharge over USB-C is not exactly fast. But for the peace of mind it buys, it is an investment we recommend without hesitation.
