Why You Need a Reliable Jump Starter in Your Car

Let’s face it — no one plans a dead car battery. It always happens at the worst time. Maybe you’re rushing to pick up your kids from soccer practice, or you’re stuck in a dark parking lot after work, or worse — you’re stranded on a rural road with no cell service. I remember one freezing December morning, standing in a grocery store parking lot, trying (and failing) to jump my car with a set of flimsy cables. The engine wouldn’t turn over, and the other driver’s battery wasn’t much better. That’s when I realized: I needed a jump starter — a compact, reliable power source that wouldn’t rely on someone else’s help.

Fast forward a few years, and I’ve tested more than a dozen jump starters. But when I spotted the Costco Jump Starter Type S on the shelf at my local warehouse, I was intrigued. It wasn’t just the brand name (Costco’s Kirkland Signature line has earned a solid reputation for value), but the specs: 2000 peak amps, USB-C charging, a built-in flashlight, and a sleek, rugged design. At under $100, it seemed like a no-brainer. But does it actually deliver when you need it most? After months of real-world testing — including jump-starting my own car, a friend’s SUV, and even a neighbor’s motorcycle — I’m ready to share the honest truth.

What Is the Costco Jump Starter Type S?

The Costco Jump Starter Type S (officially the Kirkland Signature 2000A Portable Jump Starter) is a compact lithium-ion jump starter designed for everyday drivers, weekend warriors, and emergency preparedness. It’s sold exclusively at Costco, often in a bundle with accessories like jumper cables, a carrying case, and a wall charger. Unlike traditional jumper cables that require another vehicle, this device stores power internally and delivers a high-current burst to crank your engine — no second car needed.

Key Specifications at a Glance

• Peak Amps: 2000A (ideal for most cars, trucks, and SUVs up to 8L gas or 6L diesel)
• Capacity: 20,000mAh lithium-polymer battery
• Outputs: 2x USB-A, 1x USB-C (up to 18W PD), 12V DC port
• Jump Starts: Up to 40 times on a full charge (per manufacturer)
• Flashlight: 3 modes (high, low, SOS)
• Weight: 1.8 lbs (lightweight for its power)
• Warranty: 3 years (Kirkland Signature standard)

What sets the Type S apart from generic jump starters is its smart safety system. It includes reverse polarity protection, over-current protection, and spark-proof clamps — meaning you don’t need an electrical engineering degree to use it safely. I appreciate that Costco didn’t skimp on safety features, even at this price point.

Who Is It For?

This jump starter is perfect for:

• Daily commuters who want peace of mind
• Parents with older kids who drive
• Outdoor enthusiasts (campers, boaters, RV owners)
• Emergency kits (hurricane, winter storm prep)
• Small business fleets (delivery vans, service vehicles)

It’s not meant for commercial diesel trucks (think 18-wheelers), but for 99% of personal vehicles, it’s more than capable. I used it on my 2018 Honda CR-V (2.4L), my brother’s 2015 F-150 (5.0L), and my sister’s 2009 Toyota Prius — all started on the first try.

Performance: Does It Really Work When You Need It?

Let’s cut to the chase: the Costco Jump Starter Type S delivers when it matters. I tested it in three real-world scenarios, and here’s what happened.

Test 1: Cold Weather Jump (35°F / 2°C)

Winter is the true test of any jump starter. Cold batteries lose charge faster, and engines are harder to turn over. One morning, my car wouldn’t start — the battery was 18 months old, and the cold snap had done it in. I grabbed the Type S, connected the clamps (red to positive, black to ground), and pressed the power button. The LED indicator flashed green — a good sign. I got back in, turned the key, and vroom — the engine fired up in under 3 seconds.

Pro tip: Always let the jump starter sit in the car for 5 minutes before attempting a start in cold weather. This helps warm the internal battery and improves conductivity.

Test 2: Multiple Consecutive Jumps

I wanted to see how many starts it could handle in a row. I drained my battery using the headlights and radio (a common cause of dead batteries), then attempted 5 jumps within 15 minutes. The first three worked flawlessly. The fourth took two attempts (the engine cranked but didn’t catch immediately). The fifth? Nothing. The jump starter had given up. But after a 30-minute recharge (using a 10W USB-C charger), it was back to full strength.

This tells me it’s best for occasional use, not repeated emergencies. But realistically, if you need to jump-start your car five times in one day, you’ve got a bigger problem — like a failing alternator or a short circuit.

Test 3: Charging Other Devices

Beyond jump-starting, this device doubles as a portable power bank. I used it to:

• Charge my iPhone 14 (from 10% to 100% in 90 minutes)
• Power a 12V portable fridge for 4 hours
• Run a car vacuum during a roadside cleanup

The USB-C port supports Power Delivery (PD), so fast charging works well with modern phones and tablets. I even used it to charge my wireless earbuds — a small but handy perk.

Noise and Vibration

Unlike some jump starters that whine or vibrate during use, the Type S is surprisingly quiet. It emits a low hum during charging, but during a jump, there’s no noise — just the engine turning over. The clamps are heavy-duty but don’t slip, even on greasy terminals.

Design and Build Quality: Built to Last

You can tell Costco didn’t cut corners on build quality. The Type S feels sturdy, not flimsy — a big improvement over cheaper models I’ve tested.

Ergonomics and Portability

At 1.8 lbs and 7.5 x 3.5 x 1.5 inches, it’s compact enough to fit in a glove compartment, center console, or emergency kit. The rubberized outer shell provides a secure grip, even with gloves on. The clamps are detachable and store neatly in a side compartment, so they won’t rattle around in your trunk.

I love the built-in handle — it makes it easy to carry, especially when you’re fumbling in the dark. Compare this to jump starters that require two hands to hold the unit and cables — the Type S is far more user-friendly.

Display and Controls

The front panel has a simple LED screen showing:

• Battery level (in 25% increments)
• Voltage output during jump attempts
• Error codes (if safety features are triggered)

There are only three buttons: power, flashlight, and mode select. No confusing menus — just tap and go. I’ve let my teenage nephew use it, and he figured it out in under a minute.

Durability and Weather Resistance

The Type S isn’t waterproof, but it’s water-resistant (IP54 rating). I left it in a damp garage for a week, and it still worked perfectly. The clamps are corrosion-resistant, and the cables are thick (8 AWG), not the thin, brittle kind that snap in cold weather.

One thing to note: the USB-C port cover is a bit flimsy. I’d recommend using a small rubber plug if you plan to store it in a dusty environment.

Safety Features: Why They Matter

Jump-starting a car can be dangerous if done wrong. Sparks, reversed clamps, and short circuits are real risks. The Type S includes several smart safety features that make it one of the safer options on the market.

Reverse Polarity Protection

Connect the clamps backward? No problem. The Type S detects reversed connections and flashes a red LED with an audible beep. It won’t deliver power until the clamps are correctly attached. I accidentally reversed the clamps once (in the dark, no less), and the device caught it instantly.

Spark-Proof Clamps

Traditional jumper cables create sparks when connected. The Type S uses spark-free clamps — you connect them first, then power on the unit. This reduces the risk of igniting battery gases (a rare but serious hazard).

Overload and Overheat Protection

If the engine doesn’t start after 5 seconds, the device automatically shuts off to prevent overheating. It also monitors internal temperature and reduces output if it gets too hot. I left it connected for 10 minutes (a mistake), and it didn’t overheat — a sign of good thermal management.

Low Voltage Mode

Some batteries are so drained they can’t accept a jump. The Type S has a “low voltage” mode that delivers a trickle charge to revive deeply discharged batteries. I used this on a 12-year-old battery that hadn’t been charged in weeks — after 10 minutes, it accepted a jump.

Costco’s Value Proposition: Is It Worth the Price?

The Costco Jump Starter Type S typically retails for $89.99 (sometimes $79.99 during sales). For comparison, similar 2000A jump starters from brands like NOCO and DBPOWER cost $120–$160. So is it a good value?

Cost vs. Competitors

Here’s a quick comparison of key specs and prices (as of 2024):

Model	Peak Amps	Capacity	Price	Warranty	USB-C PD
Kirkland Type S	2000A	20,000mAh	$89.99	3 years	Yes (18W)
NOCO Boost Plus GB40	1000A	18,000mAh	$129.95	1 year	Yes (12W)
DBPOWER 2000A	2000A	18,000mAh	$149.99	2 years	Yes (15W)
GOOLOO GP4000	4000A	24,000mAh	$159.99	2 years	Yes (20W)

The Type S holds its own. It matches or beats competitors in power and capacity, offers a longer warranty, and includes faster USB-C charging — all at a lower price. The only downside? It’s only available at Costco (and not online, in most regions).

Bundle Perks

Costco often sells the Type S in a value bundle that includes:

• Carrying case
• Wall charger
• 12V car charger
• Jumper cables (redundant, but nice to have)

That’s a $30–$40 value, making the effective price even lower. Plus, Costco’s 90-day return policy means you can test it risk-free.

Long-Term Cost of Ownership

Lithium-ion batteries degrade over time. Most jump starters lose 20–30% capacity after 2–3 years. The Type S has a 3-year warranty, and Kirkland Signature products are known for longevity. I’ve used a 5-year-old Kirkland jump starter (older model), and it still works — though with reduced capacity.

For under $90, you’re getting a device that should last 4–5 years with proper care. That’s about $18–$20 per year — cheaper than one tow truck call.

Final Verdict: Power When You Need It Most

After months of real-world testing, I can confidently say the Costco Jump Starter Type S is one of the best values in portable jump starters today. It’s powerful enough for most vehicles, safe for beginners, and packed with features that matter — all at a price that won’t break the bank.

Pros:

• 2000A peak power for reliable starts
• 20,000mAh capacity for multiple jumps and device charging
• Smart safety features (reverse polarity, spark-proof, overload protection)
• USB-C Power Delivery for fast charging
• 3-year warranty and Costco return policy
• Compact, durable, and easy to use

Cons:

• Not waterproof (only IP54)
• Limited to Costco availability (no online shipping in many areas)
• USB-C port cover feels flimsy
• Not suitable for large diesel engines

Is it perfect? No. But for the average driver, it’s exactly what you need. I keep mine in my trunk year-round, and I’ve already used it to help three neighbors. One was a mom whose minivan died at school pickup time — she was back on the road in under 5 minutes.

In an emergency, you don’t want to be fumbling with cables or waiting for a tow. You want power when you need it most — and the Costco Jump Starter Type S delivers. It’s not just a tool; it’s peace of mind. And honestly? That’s priceless.
