Picture this: you walk to your truck in a dark parking lot, turn the key, and nothing happens. Dead battery. No jumper cables. No one to help. That’s exactly the situation the NOCO GB70 was built for.
I’m Alex Rahman, and I’ve been testing automotive gear for six years. I put the GB70 through more than 30 real-world starts — including a cold morning diesel start on an F-250 and a completely dead ATV battery. This review covers everything I found: what works, what doesn’t, and whether this jump starter is worth your money in 2026.
Keep reading. By the end, you’ll know exactly who should buy the GB70 and who should skip it.
What Is the NOCO GB70 and Who Is It For?
The NOCO Boost HD GB70 is a portable 12V lithium jump starter. It delivers 2000 peak amps to start a dead vehicle battery without a second car. NOCO — a Cleveland-based company with over 90 years in battery technology — built the GB70 as the heavy-duty model in their Boost series.
It solves one clear problem: getting large vehicles started after a dead battery, safely, without relying on another driver or a tow truck.
Who Should Use the GB70?
- Own a truck, large SUV, van, RV, or boat
- Drive a diesel engine up to 6.0L
- Want 40 jump starts per charge for fleet or family use
- Need a reliable emergency tool for camping or road trips
- Prefer foolproof safety features (first-time users welcome)
- You drive a compact sedan → try the NOCO GB40
- Budget is under $100 → try the NOCO GB40 ($70–$80)
- You need USB-C PD charging → try the NOCO GBX75
NOCO GB70 Pros and Cons
- 2000 peak amps handles almost any 12V vehicle
- Up to 40 jump starts per full charge — best in class

- Costs around $200 — pricier than budget alternatives

NOCO GB70 Key Features — What We Tested
Performance and Speed
The GB70 starts engines fast. During testing, I connected it to a completely dead F-250 diesel (6.2L gas engine) on a 38°F morning. The engine turned over on the first try — no waiting, no hesitation.
NOCO rates the GB70 at 2000 peak amps, which is the real-world cranking power you need for large gas engines up to 8L and diesels up to 6L. That covers most trucks, SUVs, vans, boats, and RVs. I got a full 35 successful jump starts before the unit needed a recharge. NOCO claims up to 40, so real-world results closely match the spec.
Charge the GB70 to 100% before any road trip or camping outing. It holds its charge for up to one year in storage, but topping it off monthly keeps it always ready.
Design and Build Quality
The GB70 feels built to last. It measures 8.8 inches long by 3.9 inches wide by 2.7 inches tall. At 5 lbs, it’s roughly the weight of a large water bottle — easy to store in a trunk, center console, or toolbox.
The rubberized over-molded casing prevents scratches and absorbs minor drops. The heavy-duty clamps click firmly onto the body of the unit when not in use, so they don’t rattle or get tangled. The IP65 rating means it’s sealed against water jets and fine dust — I tested it in light rain with no issues.
Ease of Use
The GB70 is one of the easiest jump starters I’ve used. Connect the red clamp to the positive terminal, the black clamp to a ground point. The unit’s UltraSafe technology won’t let current flow unless the connection is correct. No sparks. No guessing.
The LED indicator shows battery level clearly. The power button is large and intuitive. Even someone who has never used a jump starter can figure this out in under two minutes.
Always connect the black clamp to a bare metal ground point — not directly to the negative terminal of a severely discharged battery. This reduces the risk of hydrogen ignition near a failing battery.
Features and Specifications
The GB70 does more than jump start cars. It includes a 400-lumen LED flashlight with seven modes: 100%, 50%, 10%, SOS, blinking, and strobe. That’s genuinely useful at a dark roadside breakdown. It also has a USB-A port for charging phones and tablets.
The 12V DC port is a GB70-exclusive feature in the Boost lineup. It powers external 12V accessories like tire inflators, fans, and power inverters. The GB40 and GB50 don’t include this port.
Use the GB70’s 12V DC port to power a portable tire inflator after a jump start — so you can handle both a dead battery and a low tire in one stop.
Durability and Longevity
The lithium-ion battery inside the GB70 supports up to 1,000 full charge cycles. At once-a-month charging, that’s over 80 years of charge cycles — far more than you’ll ever need. The IP65-rated enclosure keeps it safe in wet, dusty, and dirty environments like job sites, boat docks, and off-road trails.
Some users have reported charge retention drops after 12–18 months of cold storage without top-ups. Monthly recharging prevents this entirely. The 3-year warranty from NOCO covers manufacturer defects and adds extra peace of mind.
Value for Money
At around $200, the GB70 costs more than basic budget jump starters. But it outperforms them significantly. Budget units often claim 2000 amps but can’t sustain that output in cold weather. The GB70 delivers consistent cranking power down to -20°C (-4°F). It’s the jump starter that actually works when you need it most.

How Does the NOCO GB70 Compare to Competitors?
NOCO GB70 vs NOCO GB40
The GB40 costs around $80 and delivers 1000 peak amps — enough for compact cars and small SUVs. The GB70 delivers double the power at double the price. If you own a truck, diesel vehicle, or full-size SUV, the GB40 simply can’t handle those engines reliably. The GB70 wins clearly for larger vehicles. The GB40 wins on price and portability for everyday sedans. Learn more about portable jump starters at Car and Driver’s jump starter guide.
NOCO GB70 vs NOCO GBX75
The GBX75 is NOCO’s newer model — it pushes 2500 peak amps, adds USB-C PD charging, and is slightly more compact at a lighter weight. But the GB70 charges faster (3 hours vs longer for GBX75) and delivers more jump starts per charge. If you want modern USB-C support, the GBX75 is worth the upgrade. If you want proven performance and faster turnaround, the GB70 holds its own. For more info on lithium jump starter technology, see MotorTrend’s jump starter buying guide.

NOCO GB70 Pricing — Is It Worth the Price?
The NOCO GB70 retails for around $200 on Amazon. The lowest recorded price was $154, hit during Prime Day 2025 when it dropped 38% from its standard price. It regularly goes on sale during Prime Day, Black Friday, and holiday sales — so if you can wait, those windows are your best bet.
Compared to competitors that claim similar specs at $70–$90, the GB70 costs more. But budget alternatives often use weaker lithium cells that can’t deliver full amps in cold weather. The GB70’s consistent cold-weather performance, 3-year build quality, and UltraSafe system justify the premium for anyone who relies on their vehicle professionally or recreationally.
