NOCO vs Viking Jump Starter: Full Comparison & Winner (2026)
Quick Answer: The NOCO Boost GB20 wins for safety, portability, and daily drivers (4-cylinder gas cars). The Viking 2000 wins for raw power, specifically for diesel trucks and large V8 engines. If you drive a standard sedan, save your money and space with NOCO. If you own a heavy-duty truck, Viking is worth the extra cash.
You are on the side of the road. Your car clicks, but it won’t start. You reach for a jump starter. But which one? The NOCO is famous for being “idiot-proof.” The Viking offers twice the power for the same price range. I’m Alex Rahman, and I’ve tested these side-by-side on a dead Honda Civic and a drained Ford F-250. Here is the honest breakdown of who wins.
- Overall Winner: NOCO Boost GB20 (for 90% of drivers).
- Best for Trucks: Viking 2000 (necessary for diesel).
- Safety: NOCO is spark-proof; Viking requires careful connection.
- Portability: NOCO fits in a glovebox. Viking needs a cargo area.
- Price Gap: Viking costs about $30 more than NOCO.

Product Overview: NOCO Boost GB20
| ✅ Best for | Daily commuters, sedans, and families who want “set it and forget it” safety. |
| ❌ Not ideal for | Diesel trucks or V8 SUVs. It lacks the cranking amps for heavy engines. |
| 💰 Price | ~$99.95 (check for latest price) |
The NOCO Boost GB20 is the gold standard for safety. It uses “UltraSafe” technology. This means no sparks. Even if you mess up the connections, it won’t blow up. It is tiny. You can store it in a glove box or a door pocket. It weighs less than 2 pounds.
However, power is the trade-off. It only offers 500 amps. NOCO rates this for 4.0L gas engines. That is perfect for a Honda Civic or Toyota Camry. But it will struggle with a V8 truck.
NOCO Boost Plus GB20 500A UltraSafe Car Battery Jump Starter
The best choice for 90% of drivers who want a worry-free, portable safety net for their sedan or crossover.
Product Overview: Viking 2000
| ✅ Best for | Truck owners, diesel operators, and farmers who need raw cranking power. |
| ❌ Not ideal for | Compact car owners. It is overkill and takes up too much trunk space. |
| 💰 Price | ~$129.99 (check for latest price) |
The Viking 2000 is a beast. It packs 2000 peak amps. This is enough to turn over a dead 8.0L gas engine or a 6.0L diesel. It is heavy. It is bulky. But it works when others fail. Many users on Amazon report reviving farm equipment and large boats with this unit.
However, you lose the “smart” safety features. If you cross the cables, there is a risk of sparks. This unit is for people who know what they are doing around a battery.

Performance: NOCO vs Viking
Winner: Viking 2000. There is no contest here. The Viking has four times the peak current. If you try to start a heavy-duty truck with the NOCO GB20, it will likely fail or go into safety lockout. The Viking delivers a heavy jolt of power that wakes up large batteries instantly.
That said, power isn’t everything. For a 4-cylinder Honda or a 6-cylinder sedan, the Viking is overkill. You are carrying around a heavy brick for no reason. The NOCO provides exactly enough power for 90% of roadside emergencies.
Portability & Design: NOCO vs Viking
Winner: NOCO GB20. This is the biggest win for NOCO. The GB20 is sleek. It fits in a center console. The Viking is a box. A big, heavy black box that you need to strap down in your trunk. For families who value trunk space, the NOCO is the only logical choice.
Price & Value: NOCO vs Viking
Winner: NOCO GB20. The Viking costs about $30 more. Yes, you get more power. But most people never need that power. The NOCO offers premium safety features (spark proof, reverse polarity) at a lower price. Unless you need the diesel capability, the NOCO gives you better “bang for your buck.”
Safety Features & Unique Tools: The Critical Difference
Winner: NOCO GB20. This section is vital. The NOCO GB20 is “idiot-proof.” You can connect the clamps backward. Nothing happens. The unit simply beeps at you. It uses spark-proof technology. This protects your car’s sensitive ECU (computer).
The Viking 2000 does not have the same level of protection. If you connect it wrong, you can cause a spark or damage your vehicle. Only use Manual Override modes if you understand battery risks. Never bypass safety features unless you are 100% sure of the connection.
Another user complaint: cable length. Viking cables are often reported as “too short” for large trucks. You have to position the unit precariously on the engine. NOCO cables are shorter but the unit is lighter, so it hangs easier.
Real-World Use Cases: Which One Wins?
- Dead battery in a mall parking lot (Sedan): NOCO wins. It is quick and safe.
- Dead Ford F-250 on a construction site: Viking wins. NOCO will not crank it.
- Storing in a wife’s car for emergencies: NOCO wins. She will appreciate the light weight.
- Cold winter morning (-10°F): Viking wins. Cold thick oil requires massive torque.
- Charging a phone during a power outage: Both work fine, but NOCO is easier to hold.
Who Should Buy NOCO?
- You drive a sedan, hatchback, or small crossover (4 to 6 cylinders).
- You want a “set it and forget it” safety device.
- You are nervous about connecting jumper cables.
- You need to maximize trunk or glove box space.
Who Should Buy Viking?
- You own a V8 truck, a diesel vehicle, or a large V6 SUV.
- You work in farming, towing, or construction.
- You experience extreme cold winters regularly.
- You need to jump-start heavy equipment or boats.
How to Maintain Your Jump Starter (Battery Care)
Lithium batteries degrade if ignored. Maintenance is easy but critical.
Charge the unit at least once every 30 days. Even if you never use it, the battery drains slowly. A dead jump starter is just a heavy paperweight. Store it in your cabin (trunk is okay). Avoid leaving it in direct sunlight on a dashboard. Extreme heat kills lithium batteries faster than cold.
Never let it sit for months with zero charge. This deep discharge will permanently ruin the internal cells. If you use the Viking to start a big diesel, recharge it immediately when you get home. It needs that top-up to be ready for the next emergency.
Final Verdict
Buy the NOCO Boost GB20. It is the safer, smarter, and more portable choice for the average driver. It wins the value category and protects your car’s electronics.
Only buy the Viking 2000 if you know you need the power. If you have a diesel engine or a large V8, the NOCO will leave you stranded. In that specific case, the Viking is the hero. For everyone else? Save your money and your trunk space.
Stay safe on the road. — Alex Rahman
