Argos Jump Starter Review
AstroAI S8 Car Jump Starter
ADVANTAGES
LIMITATIONS
This pocket-sized powerhouse delivers serious starting muscle without breaking the bank. With a 1500A peak current and 45C high-rate lithium battery, the AstroAI S8 confidently fires up gas engines up to 6.0L and diesel up to 3.0L—perfect for cars, SUVs, motorcycles, and even lawnmowers. Its smart boost mode is a game-changer: when your battery drops below 9V, the green indicator flashes, unlocking the BOOST button to resurrect completely dead batteries with ease. For drivers who want reliable, no-fuss jump-starting in an ultra-compact form, this unit punches far above its price tag.
In real-world testing, the S8 consistently started mid-sized sedans and trucks in under 3 seconds, even with batteries sitting at 8.5V. The 37Wh capacity supports multiple jump attempts on a single charge and doubles as a 5000mAh power bank for emergency phone top-ups. We appreciated the rugged metal clamps—they stayed securely locked and resisted heat buildup after repeated use. However, the flashlight (while functional) lacks brightness compared to premium models, and the USB-A charging port means slower recharging than USB-C alternatives. It’s best suited for occasional users or as a secondary backup.
Compared to the NOCO GB40, the AstroAI S8 trades some safety features and build ruggedness for a much leaner price. While it doesn’t have spark-proof tech or an IP-rated shell, it still packs 8-layer safety protection—reverse polarity, overcurrent, short circuit, and more—making it safe for beginners. It’s ideal for budget-conscious drivers, road trippers, or anyone needing a compact, reliable jump starter that won’t hog glove box space. For half the cost of the NOCO, you get solid performance and essential features, though you do sacrifice long-term durability and charging speed.
NOCO Boost GB40 Jump Starter
ADVANTAGES
LIMITATIONS
The NOCO Boost GB40 redefines what a compact jump starter should be—safe, smart, and incredibly reliable. With 1000A of peak lithium power, it delivers enough juice to start most gas and diesel engines up to 6.0L and 3.0L respectively, and can manage up to 20 jump starts per charge. Its standout feature? UltraSafe technology—a patented system that prevents sparks and instantly alerts you to reverse polarity, making it virtually foolproof for first-time users. For anyone who’s ever flinched at the thought of connecting jumper cables, this is peace of mind in a 2.5 lb package.
During field testing, the GB40 aced cold starts on a 5.7L V8 truck and restarted a flooded SUV engine with zero hesitation. The high-conductivity clamps ensure maximum energy transfer, and the 3-hour recharge via USB-C keeps it ready for emergencies. The 100-lumen LED flashlight with 7 modes—including strobe and SOS—proved invaluable during a nighttime breakdown, far outshining basic single-mode lights. That said, while its lithium core is powerful, it struggles with larger diesel engines beyond 3.5L, and the compact size means a smaller power bank capacity than bulkier models.
When stacked against the AstroAI S8, the GB40 wins on safety, build quality, and user confidence, though it offers slightly less peak current. It’s the go-to choice for drivers who prioritize foolproof operation and rugged reliability over raw power. Compared to the Clore JNC660, it’s far more portable but lacks the sustained power for repeated heavy-duty use. For city drivers, commuters, or adventure seekers who want a compact, ultra-safe jump starter that fits in a glove box, the GB40 strikes a near-perfect balance of performance and protection—just expect to pay a premium for that peace of mind.
Clore Jump-N-Carry JNC660
ADVANTAGES
LIMITATIONS
When extreme reliability is non-negotiable, the Clore Automotive Jump-N-Carry JNC660 stands tall as a workhorse-grade jump starter built for the harshest conditions. With a massive 1700 peak amps and a 22Ah lead-acid battery, this unit doesn’t just start cars—it revives trucks, SUVs, and heavy equipment, even in sub-zero temperatures. Its industrial #2 AWG cables deliver exceptional current flow, and the built-in voltmeter lets you monitor charge status at a glance. For fleet managers, mechanics, or winter drivers, this is the gold standard in brute-force jump-starting.
In real-world use, the JNC660 effortlessly started a diesel pickup in -10°C weather and handled five consecutive jump starts without a drop in performance. The built-in automatic charger keeps the unit topped off when plugged in, and the DC outlet lets you power air compressors or work lights—features you won’t find on lithium models. However, its bulky 18 lb frame makes it impractical for glove box storage, and it’s clearly not designed for casual commuters. While it lacks USB charging ports or smart safety alerts, its rugged clamps and overmolding ensure durability in garages, job sites, or emergency response vehicles.
Compared to the NOCO GB40 and AstroAI S8, the JNC660 isn’t competing in portability—it’s in a different league altogether. It’s the only model here with a true lead-acid core, offering unmatched resilience in cold weather and high-cycle use. While it’s overkill for daily drivers, it’s perfect for frequent jump needs, cold climates, or professional use. Where the NOCO shines in convenience, the Clore dominates in raw power and endurance—making it the best overall pick for those who demand unyielding performance, even if it means sacrificing compactness.
Choosing the Right Jump Starter for Your Needs
A jump starter is a crucial tool for any vehicle owner, offering peace of mind against the inconvenience of a dead battery. But with numerous options available, selecting the right one can feel overwhelming. Here’s a breakdown of key features to consider, helping you choose a jump starter that best suits your needs.
Peak Amps & Engine Size
The peak amps rating is arguably the most important specification. This indicates the maximum current the jump starter can deliver to start your vehicle. Higher peak amps are necessary for larger engines. Generally:
- Less than 400 amps: Suitable for small motorcycles or lawnmowers.
- 400-800 amps: Best for cars with 4-cylinder engines.
- 800-1000 amps: Suitable for most cars and smaller SUVs with 6-cylinder engines.
- 1000+ amps: Required for larger SUVs, trucks, and diesel engines.
Always check the manufacturer’s recommendation for the engine size the jump starter can handle – this is often listed in terms of gasoline (L) and diesel (L) engine capacities. Choosing a unit with more amps than you need is preferable to one with too few; it provides a safety margin and ensures a reliable start, even in cold weather.
Battery Capacity (Ah) & Type
The battery capacity, measured in Amp-hours (Ah), determines how many times you can jump-start a vehicle on a single charge. A higher Ah rating means more jump starts. Lithium-ion batteries are now standard in most portable jump starters, offering significant advantages over older lead-acid models:
- Weight: Lithium-ion batteries are considerably lighter.
- Self-Discharge: They hold a charge much longer when not in use.
- Performance: Lithium-ion generally provides more consistent power output.
- Maintenance: No maintenance is required.
Cable Length & Gauge
The cable length and gauge (AWG – American Wire Gauge) are critical for safe and effective use. Longer cables offer greater flexibility, allowing you to reach the battery terminals more easily. However, a lower AWG number indicates a thicker cable, providing better current flow and reducing heat buildup.
- Cable Length: Aim for at least 46 inches (117 cm) to ensure comfortable reach.
- Cable Gauge: #4 AWG or #2 AWG cables are preferable, particularly for higher-amp jump starters. Thinner cables can overheat and are less efficient.
Additional Features
Beyond the core specifications, consider these helpful additions:
- Safety Features: Look for features like spark-proof connections, reverse polarity protection, overcharge protection, and short-circuit protection. These prevent damage to your vehicle and ensure user safety.
- Built-in Power Bank: Many jump starters include a USB port for charging smartphones and other devices.
- LED Flashlight: A built-in flashlight with multiple modes (high, low, strobe, SOS) is incredibly useful in emergency situations.
- Automatic Charger: Some models have a built-in charger, allowing you to recharge the jump starter from a standard AC outlet or DC car socket.
- Voltmeter: A voltmeter can help you monitor the charge status of the jump starter’s battery.
