Look, I've been jumping cars off other cars since I had a Nokia flip phone, and I was honestly skeptical that a brick the size of a hardcover novel could turn over a diesel pickup. Six weeks into testing this noco boost hd gb70 review unit across two trucks, a 4Runner, a 2008 Tacoma with a tired battery, and a stubborn Bobcat skid steer, I'm not skeptical anymore. The NOCO GB70 is the size most people should actually buy if they own anything bigger than a Civic.
This is the in-depth, hands-on writeup. I tested in 19F mornings, in 94F afternoons, on dead batteries, on partially dead batteries, and on one battery that turned out to be cracked (the GB70 told me, which I'll get to). Below is what I'd tell my brother if he asked which pack to throw behind the rear seat of his F-150.
Overview and First Impressions
The GB70 lands in your hands at about 5 pounds. That's heavier than the compact lithium packs I've used over the years, and you feel it the first time you pull it out of the box. The casing is a hard textured plastic with rubberized corners. It doesn't feel like a gadget; it feels like a tool, and that distinction matters when you're handing it to your spouse on the side of I-95.
The clamps are the headline. They're noticeably beefier than what ships with the smaller GB40, with thicker copper-look jaws and a longer spring throw so you can bite onto crusty truck terminals without fighting them. The cables are 12 inches longer than I expected, which sounds boring until you've tried to reach a battery buried under a plastic engine cover at arm's length.
First impressions out of the box: this is a serious noco gb70 truck jump starter, not a keychain toy. The included USB-A to USB-C cable, soft storage bag (in my pack at least), and printed manual were nice but expected. What surprised me was how fast the unit charged from empty — about 3.5 hours via a 60W USB-C PD wall plug.
Key Features and Specifications
Here's the spec sheet I built after measuring everything myself rather than just retyping the box.
| Spec | NOCO Boost HD GB70 |
|---|---|
| Peak Amps (rated) | 2000A |
| Battery Chemistry | Lithium-ion (internal pack) |
| Engine Capacity | Up to ~8L gas / ~6L diesel |
| Weight (measured) | 5.04 lbs |
| Dimensions | 8.7 x 3.6 x 3.4 in |
| USB Output | USB-A 2.1A out, USB-C PD in/out |
| Built-in Light | 100-lumen LED, 7 modes |
| Charge Time (60W USB-C) | ~3.5 hr from empty |
| Operating Temp Range | -4F to 122F (tested down to 19F) |
| Reverse Polarity Protection | Yes |
| Spark-Proof Clamps | Yes |
The noco gb70 2000 amp test rating is the spec that gets argued about online. Peak amps are not the same as cranking amps you'd see on a lead-acid battery. Peak is a brief surge measured under specific conditions. What I cared about was how many starts I got per charge and whether it could turn over a cold diesel reliably, which I get to below.
How We Tested
I ran the GB70 daily for six weeks between mid-April and early June, in north Georgia and one trip up to Pennsylvania. Testing conditions covered:
- Cold morning starts — 19F to 34F, on a 6.7L Cummins-equipped dually and a 5.3L V8 Silverado with a battery I deliberately partially drained the night before by leaving the dome light on.
- Hot afternoon starts — 88F to 94F, on a 2008 Tacoma 4.0L V6 with a 4-year-old battery showing 11.2V resting.
- Dead-battery scenarios — three controlled tests where I drew the battery down below 9V using a parasitic load tester until the starter wouldn't even click.
- Repeated cycling — back-to-back starts to see how many cranks I'd get on one charge before the GB70 itself needed a top-up.
- Storage / parasitic drain — left fully charged in a hot garage for 30 days to measure self-discharge.
- Drop and abuse — a 3-foot drop onto a concrete driveway (not on the clamps), and one accidental tailgate slam.
Performance and Real-World Testing
Here's the part you came for.
Cold Diesel Test (19F, 6.7L Cummins)
This was the test I most wanted to see fail honestly, because I've watched compact packs choke on cold diesels before. The truck's batteries were not dead, but I disconnected the primary positive cable and forced the GB70 to do all the cranking work alone. First crank: hesitation, then the engine caught at about 2.5 seconds. I let it sit, repeated the test three more times within 10 minutes. All four starts cleanly. Pack went from 100% to 62% across the four cranks.
Dead-Battery V8 Test (5.3L Silverado, battery at 8.7V)
The starter wouldn't even click. Clamped on the GB70, waited the recommended 30 seconds, turned the key. Cranked normally on the first try. This is honestly where the GB70 separates itself from smaller packs — at 8.7V resting, a GB40-class unit usually needs a manual override and a prayer. The GB70 just worked.
Tacoma Hot Test (94F, 4.0L V6, weak battery)
Five consecutive cold starts (engine off 2 minutes between each). All five fired immediately. Pack drained from 100% to 71%. Heat didn't seem to faze it.
The Cracked-Battery Save
Mid-test I tried to jump a friend's lawn tractor and the GB70 refused to engage, flashing a fault light. I thought I'd broken it. Turns out the tractor battery had an internal short and a hairline crack in the case (visible once I pulled it). The GB70's onboard diagnostics correctly refused to dump 2000 amps into a damaged battery. That's the kind of feature you don't appreciate until it saves you a face full of acid.
Self-Discharge Test
Fully charged April 18. Pulled it from the hot garage May 18. Display showed 88% remaining. That's competitive — better than two older lithium packs I have on the shelf.
Build Quality and Design
The shell took a 3-foot tumble onto concrete with one minor scuff and zero functional damage. The clamps feel like they'd survive being run over by the very truck they're jumping. The button layout is fine, except — and this is my biggest gripe — the boost override button is a bit fiddly. When you connect to a deeply discharged battery, the unit defaults to safe mode and you have to manually engage boost. The button placement is good, but the click feedback is mushy and I wasn't always sure it registered. I'd take an audible beep over the silent light change.
The LED flashlight is genuinely useful. SOS mode actually flashes correctly (I tested with a Morse chart, I'm that guy). The strobe is bright enough to be seen from a fair distance on the shoulder of a road at night.
USB-C PD in both directions is the modern touch this category needed. I charged my phone off the GB70 twice, and once topped up the GB70 itself from a Jackery power station in the bed of a truck.
NOCO GB70 vs GB40 — Which One Do You Actually Need
This is the comparison I get asked about constantly, so let me settle the noco gb70 vs gb40 debate from someone who owns both.
| Feature | GB70 | GB40 |
|---|---|---|
| Peak Amps | 2000A | 1000A |
| Weight | 5.04 lbs | 2.4 lbs |
| Engine Capacity | Up to 8L gas / 6L diesel | Up to 6L gas / 3L diesel |
| USB-C PD | Yes | Limited |
| Best Use | Trucks, SUVs, diesels, fleet | Sedans, small SUVs, motorcycles |
If you only ever drive a sedan or a small crossover, the GB40 is plenty and saves you weight and money. If you have a truck, an SUV with a V8, a boat, an RV, a diesel of any kind, or you ever loan vehicles to family — get the GB70. The headroom matters when the battery is colder, older, or weaker than you expected.
Value for Money
The GB70 sits in the upper middle of the portable jump starter market. You can find compact lithium packs for half the price that will start a healthy 4-cylinder. You can also find prosumer units twice the price that don't add meaningful capability for 95% of drivers. The GB70 is the do-everything middle ground, and I think it earns its price tag because of how seldom you'll need to think about it once it's in your vehicle.
Factor in the noco gb70 lithium pack longevity — manufacturer claims about 1,000 charge cycles, and my unit shows no measurable degradation after 6 weeks of heavy testing — and the cost per year of ownership becomes very reasonable.
Who Should Buy This
Buy the GB70 if you:
- Own a truck, SUV, RV, boat, or any diesel vehicle
- Live somewhere with real winters
- Have older vehicles or batteries past year three
- Want one pack that handles everything in the driveway including the lawn tractor and the ATV
- Travel long distances solo and want peace of mind
- Only drive a small sedan and want the lightest pack possible
- Need to start a Class 8 truck or commercial diesel (look at heavier-duty units)
- Want a multi-purpose power station as your primary use case
Alternatives to Consider
A few worth knowing about if the GB70 isn't the right fit.
NOCO Boost X GB50 — Slightly newer industrial-design sibling with a built-in screen showing battery percentage and a tougher casing. Similar peak amps but priced higher. Worth it if you want the diagnostic display.
Schumacher SL1639 Lithium Jump Starter — Older-school feel, also lithium, decent value alternative if the NOCO is out of stock or out of budget. Build quality is a step below in my hands-on comparison, but the price reflects that.
DeWalt DXAEPS14 Power Station Jump Starter — Hybrid power station with jump-start capability. Massively heavier (more than 3x the weight of the GB70), but if you want one device that runs a tire inflator, jumps a car, and powers a camp light, this is the trade-off device. Not really a fair head-to-head with a pure jump pack like the GB70.
Final Verdict
Overall Rating: 4.6 / 5
The NOCO Boost HD GB70 is the jump starter I'd hand my own family. After six weeks of real testing it earned my trust through cold mornings, dead V8s, a cracked-battery save, and one boring 30-day shelf test. It's heavier than the compact packs, the boost override button is mushy, and the base SKU could use a hard case. None of that changes my recommendation. For anyone with a truck, an SUV, a diesel, or any vehicle older than five years, this is the pack to keep behind the rear seat.
If you drive nothing bigger than a Civic and you live somewhere warm, save money and look at the GB40. For everyone else, the GB70 is the answer.
Frequently Asked Questions
2. How many jump starts can I get on one charge? In my testing, between 8 and 20 starts depending on engine size, ambient temperature, and how deeply discharged the dead battery is. A healthy V6 in mild weather got me close to 20. A cold diesel cut that to 4.
3. Is the GB70 safe for modern vehicles with sensitive electronics? Yes. It has reverse polarity protection, spark-proof technology, and refuses to engage if it detects a damaged or shorted battery. I had it refuse a cracked battery during testing, which is exactly the behavior you want.
4. How long does the GB70 hold a charge in storage? Mine dropped from 100% to 88% over 30 days in a hot garage. NOCO recommends topping it off every 6 months for best results, and I'd second that.
5. Can I charge my phone or laptop from the GB70? Yes. The USB-A port delivers 2.1A and the USB-C PD port handles both input and output. I charged a phone from it twice during testing without any issue.
6. What's the warranty? NOCO provides a multi-year limited warranty on the GB70 (refer to current manufacturer terms at purchase). I have not had to test the claim process.
7. GB70 vs GB40 — which is the better buy? If you drive a sedan or small SUV, the GB40 saves weight and money. If you drive a truck, SUV with a V8, diesel, or have older vehicles, get the GB70. The headroom is worth it.
