| Starts per charge | Up to 40 |

Starting Power
NOCO rates the GB70 for gasoline engines up to 8.0 liters and diesels up to 6.0 liters. That covers the vast majority of pickups and full-size SUVs, along with boats and RVs with smaller engines. You also get up to 40 starts per charge, so it can help more than one stranded driver before it needs a recharge.
Safety You Can Trust
Like every Boost model, the GB70 has spark-proof technology and reverse polarity protection. It will not send current if the clamps are connected incorrectly, which takes most of the risk out of jump-starting.
Flashlight and Power Bank
The GB70’s 400-lumen LED is four times brighter than the GB40’s light, with seven modes including SOS and strobe. The built-in power bank charges phones and tablets, and the unit recharges in about six hours over USB-C.
GB70 vs GB40 vs GB150
- GB40: 1000A, 6.0L gas / 3.0L diesel, 2.5 lb
- GB70: 2000A, 8.0L gas / 6.0L diesel, 5.0 lb
- GB150: 3000A, 9.0L gas / 7.0L diesel, 7.5 lb
For most truck owners, the GB70 is the sweet spot between size and power.
Who the GB70 Is Built For
The GB70 sits in the middle of NOCO’s lineup, and it is the one many mechanics and truck owners recommend. Its 2000 amps are rated for gas engines up to 8.0 liters and diesel engines up to 6.0 liters. That covers full-size pickups such as the F-150, Silverado and Ram 1500, large SUVs like the Tahoe and Expedition, and many diesel trucks.
It is also a good choice for drivers in cold climates. A battery loses a large share of its power below freezing, and a thick-oil engine needs more current to turn over. Having extra amps in reserve gives you a much better chance of a first-try start on a winter morning.
Using the GB70 Safely
NOCO’s UltraSafe system prevents sparks and protects against reverse polarity, so the GB70 will not send power if the clamps are on the wrong terminals. The Manual Override mode is there for completely dead batteries, but it removes those protections, so double-check the clamps before using it.
- Turn off the ignition and all accessories before connecting.
- Attach the red clamp to positive and the black clamp to negative or a solid ground.
- Press the power button. The LEDs show that the connection is correct before power flows.
- Crank the engine for no more than a few seconds, then rest 30 seconds between tries.
- Once running, turn the unit off and remove the clamps, black first.
GB70 vs GB40 vs GB150 at a Glance
| Model | Peak amps | Gas / diesel | Weight | Recharge |
|---|---|---|---|---|
| NOCO Boost GB40 | 1000A | 6.0L / 3.0L | 2.5 lb | About 3 hours |
| NOCO Boost GB70 | 2000A | 8.0L / 6.0L | 5.0 lb | About 6 hours |
| NOCO Boost GB150 | 3000A | 9.0L / 7.0L | 7.5 lb | About 7 hours |
For most truck and SUV owners, the GB70 is the right balance. The GB40 is lighter but can struggle with V8s and diesels. The GB150 adds more power than most drivers will ever need and is noticeably heavier.
Extra Uses Beyond Jump Starting
The GB70 doubles as a power bank. Its USB output charges phones and tablets, and the 12V output can run small 12V devices such as a tire inflator or a cooler for a short time. On a camping trip or during a power outage, that makes it more useful than a simple jump pack.
The 400-lumen flashlight has seven modes, including SOS and strobe, which helps if you break down at night. It is bright enough to light up an engine bay or the side of the road while you work.
Care and Warranty
Recharge the GB70 after every jump and every three to six months in storage. A full recharge takes about six hours, so it is best to do it overnight. Keep it somewhere that does not get extremely hot, such as under a seat rather than in a black trunk in summer.
NOCO covers the GB70 with a one-year warranty. Look after the clamps and cables, avoid dropping the unit on hard surfaces, and it should serve for many years.
Common Mistakes to Avoid
- Buying a jump starter that is too small for a V8 or diesel.
- Leaving the unit uncharged for a year and finding it flat in an emergency.
- Clamping onto the wrong terminal and forcing Manual Override.
- Cranking the engine for too long without rest.
- Storing it in a sealed trunk through extreme summer heat.
Who Should Buy the NOCO Boost GB70?
Buy it if you drive a pickup, full-size SUV or diesel up to 6.0L, or you want extra starts per charge.
Skip it if you drive a compact car. The smaller and lighter NOCO GB40 will do the job.
Alternatives to Consider
- NOCO Boost GB40: Smaller 1000A model for cars and small SUVs.
- NOCO Boost GB150: 3000A for engines up to 9.0L gas and 7.0L diesel.
- Clore Jump-N-Carry JNC660: A classic lead-acid unit trusted by shops.
Final Verdict
The NOCO Boost GB70 is the jump starter most truck owners should buy. It has the power for big engines, the safety features beginners need and enough capacity for multiple jumps. It is larger than the GB40, but still easy to keep behind a seat.
