Jump starters have evolved from clunky, unreliable devices to sleek, high-capacity power banks capable of reviving even large vehicles. The Costco jump starter Type S stands out for its balance of power, portability, and smart features. Unlike traditional jumper cables, which require another car and a risky connection process, this device is self-contained and safe for beginners. Whether you’re a daily commuter, a weekend adventurer, or a parent shuttling kids to school, having one in your trunk can mean the difference between a minor hiccup and a major headache.

What Is the Costco Jump Starter Type S?

A Closer Look at the Device

The Costco jump starter Type S is a lithium-ion-powered portable jump starter designed to revive dead car batteries quickly and safely. Unlike older lead-acid jump starters, this model is lightweight (about 2.5 pounds), compact (fits in a glove compartment), and equipped with modern safety features. It’s not just for cars—it can jump-start motorcycles, SUVs, trucks, and even small boats with 12V batteries. The “Type S” designation refers to its specific model line, optimized for versatility and user-friendliness.

What makes it special? First, it delivers up to 1,000 peak amps—enough to handle most 6L gas and 3L diesel engines. Second, it doubles as a power bank for phones, tablets, and other USB devices. Third, it includes built-in safety tech to prevent sparks, reverse polarity, and overcharging. No more fumbling with cables or risking electrical damage. Just connect, power up, and go.

Key Specifications

• Battery Capacity: 18,000 mAh (milliamp hours)
• Peak Current: 1,000A
• Jumps Per Charge: Up to 20 (depending on engine size)
• USB Outputs: Dual ports (5V/2.1A and 5V/1A)
• Weight: 2.4 lbs
• Dimensions: 7.5 x 3.5 x 1.5 inches
• LED Flashlight: 3 modes (steady, strobe, SOS)

These specs make it ideal for emergencies. For example, if you accidentally leave your headlights on overnight, the Costco jump starter Type S can typically jump your car 2–3 times before needing a recharge. The dual USB ports mean you can charge your phone while waiting for roadside assistance or powering a GPS device on a long trip.

Real-World Performance: How Well Does It Work?

Jump-Starting Different Vehicles

I’ve tested the Costco jump starter Type S on three vehicles: a 2018 Honda Civic (1.5L turbo), a 2015 Ford F-150 (5.0L V8), and a 2020 Harley-Davidson Sportster (1.2L). Here’s what I found:

• Honda Civic: Started on the first try. The device showed “ready” in 10 seconds, and the engine turned over instantly.
• Ford F-150: Took two attempts. The first try cranked but didn’t ignite. After a 30-second rest (recommended by the manual), it started smoothly. This is normal for larger engines—they require more sustained power.
• Harley-Davidson: One and done. The motorcycle battery was completely dead, but the jump starter delivered enough current to fire up the engine within 5 seconds.

Pro tip: Always wait 30–60 seconds after connecting the clamps before attempting to start the engine. This gives the jump starter time to stabilize and deliver maximum power. Also, avoid jump-starting a vehicle with visible battery damage (cracks, leaks)—safety first!

Charging Devices and Emergency Use

Beyond jump-starting, this device shines as a power bank. I charged my iPhone 13 from 15% to 100% in under 90 minutes using the 2.1A USB port. The LED flashlight was a lifesaver during a night-time breakdown. Its strobe mode helped flag down a passing driver, while the SOS function (three short flashes, three long, three short) could signal for help in remote areas.

One caveat: Charging multiple devices while the flashlight is on drains the battery faster. For example, running the flashlight (steady mode) and charging a phone reduced the jump starter’s capacity by ~30% in 4 hours. If you’re on a multi-day camping trip, bring a solar charger to top it up.

Safety Features That Set It Apart

Smart Protection Systems

Safety is critical when dealing with car batteries. The Costco jump starter Type S includes several fail-safes:

• Reverse Polarity Protection: If you accidentally connect the clamps backward, the device won’t power on. An LED warning flashes red, and a voice prompt says, “Reverse connection.”
• Spark-Proof Technology: The clamps won’t spark when touched together, reducing fire risk.
• Over-Voltage Protection: Prevents damage to your vehicle’s electrical system.
• Low-Temperature Operation: Works in temperatures as low as -4°F (-20°C), making it reliable in winter.

I tested the reverse polarity feature by intentionally swapping the clamps. True to form, the device refused to activate until I corrected the connection. This is huge for beginners who might panic in a stressful situation.

User-Friendly Design

The jump starter’s interface is simple: a power button, a mode switch (jump start vs. USB power), and a digital display showing battery percentage. The clamps are color-coded (red for positive, black for negative) with ergonomic grips. Even if you’ve never used a jump starter before, the included quick-start guide makes setup intuitive.

One minor gripe: The clamps are slightly bulky. They fit well on standard battery terminals but can be tricky to attach to tight spaces (e.g., some European cars). A longer cable (currently 8 inches) would help, but it’s a small trade-off for the device’s compact size.

Costco Jump Starter Type S vs. Competitors

How It Stacks Up

Let’s compare the Costco jump starter Type S to three popular alternatives: the NOCO Boost Plus GB40, the Tacklife T8, and the Stanley J5C09. Here’s a quick data table:

Feature	Costco Type S	NOCO GB40	Tacklife T8	Stanley J5C09
Peak Amps	1,000A	1,000A	800A	1,000A
Battery Capacity	18,000 mAh	18,000 mAh	18,000 mAh	14,000 mAh
Weight	2.4 lbs	2.4 lbs	2.6 lbs	2.9 lbs
USB Ports	Dual	Single	Dual	Single
Flashlight	3 modes	3 modes	2 modes	1 mode
Price (Avg.)	$89.99	$119.99	$79.99	$89.99

The Costco jump starter Type S holds its own. It matches the NOCO GB40 in power and safety but costs $30 less. The Tacklife T8 is cheaper but lacks the Type S’s robust safety features (e.g., voice prompts, spark-proof clamps). The Stanley J5C09 has a lower battery capacity and heavier build, making it less ideal for portability.

Where the Type S truly wins is value. Costco often bundles it with a carrying case, jumper cables, and a USB-C charging cable—essentials that competitors sell separately. Plus, Costco’s return policy (90 days, no questions asked) reduces the risk of buyer’s remorse.

Tips to Maximize Your Jump Starter’s Lifespan

Proper Charging and Storage

Lithium-ion batteries degrade if left unused. To keep your Costco jump starter Type S ready:

• Recharge every 3 months: Even if you don’t use it, lithium-ion batteries lose charge over time. A quarterly top-up preserves capacity.
• Store in a cool, dry place: Avoid extreme temperatures. Heat (above 104°F/40°C) and cold (below 32°F/0°C) reduce efficiency.
• Use the right charger: Always charge with the included 12V/2A adapter. Fast chargers (e.g., 18W USB-C PD) can overheat the battery.

I learned this the hard way. I left my jump starter in my trunk during a heatwave (temperatures hit 110°F). When I tested it a month later, the battery held only 60% charge. After switching to a garage storage spot, it returned to 90%+ after recharging.

When to Retire It

Most lithium jump starters last 3–5 years. Signs it’s time to replace yours:

• Fewer than 10 jumps per charge (down from 20)
• Slow charging (takes over 5 hours from 0% to 100%)
• Physical damage (swollen battery, cracked case)

Don’t push it—a failed jump starter in an emergency defeats the purpose. Set a calendar reminder to check its health annually.

Final Verdict: Is the Costco Jump Starter Type S Worth It?

After months of testing, I can confidently say the Costco jump starter Type S is one of the best portable power solutions for drivers. It’s powerful enough for most vehicles, compact enough to fit in a glove box, and packed with safety features that make it foolproof for beginners. The dual USB ports and multi-mode flashlight add serious utility, turning it into a 3-in-1 emergency tool.

Yes, it has minor flaws—the clamps could be longer, and the flashlight drains the battery faster than expected. But these are small compromises for a device that costs less than $100 and could save you hundreds in towing fees or roadside assistance calls. Plus, Costco’s return policy and frequent sales (I got mine for $79.99 during a Black Friday deal) make it a low-risk purchase.

Who should buy it? Anyone who drives regularly. Whether you’re a city commuter, a road-tripper, or a parent with a busy schedule, the Costco jump starter Type S is an insurance policy against dead batteries. It’s not just a gadget—it’s peace of mind in a sleek, portable package. So next time you’re at Costco, skip the bulk toilet paper and grab one of these instead. Your future self will thank you.
