Why You Need a Reliable Jump Starter (And Why Costco’s Type S Stands Out)

Let’s be honest—there’s nothing worse than being stranded with a dead car battery. Whether it’s a cold winter morning, a late-night grocery run, or a sudden power failure after leaving your lights on, a dead battery always seems to happen at the worst possible time. I remember one particularly frustrating evening when my sedan wouldn’t start in a dimly lit Costco parking lot. I had my phone, a flashlight, and a friendly employee who offered to help, but no jumper cables or another car in sight. That’s when I realized: I needed a portable jump starter—one that’s powerful, easy to use, and doesn’t take up half my trunk.

Enter the Costco Type S jump starter. This compact, all-in-one device isn’t just another battery pack. It’s designed for real-world emergencies, offering not only jump-starting power but also USB charging, built-in flashlights, and smart safety features. As someone who’s tested several models over the years, I was curious: could this $80–$100 unit from a big-box warehouse actually deliver when it matters most? After weeks of testing in real-life scenarios—from sub-zero temperatures to jump-starting a 6-cylinder SUV—I’ve got the full scoop. Whether you’re a daily commuter, a road-tripper, or just want peace of mind, this review will help you decide if the Costco Type S jump starter is the best portable power solution for your emergency kit.

What Is the Costco Type S Jump Starter?

A Closer Look at the Product Line

The Costco Type S jump starter isn’t a single model but a family of portable power stations sold exclusively at Costco warehouses and online. These units are manufactured by Type S, a brand known for creating practical, no-nonsense automotive accessories. The jump starters come in several versions, typically ranging from 12,000 to 20,000 mAh (milliamp-hours) of internal battery capacity. The most popular model, the Type S 20000mAh Smart Jump Starter, is the focus of this review.

What sets the Type S apart from generic jump starters is its dual-purpose design. It’s not just a car battery booster—it’s also a portable power bank with multiple USB ports, a built-in LED flashlight, and smart circuitry to prevent overcharging or reverse polarity. Unlike older jumper boxes that were bulky and heavy, the Type S models are sleek, lightweight (under 2 pounds), and small enough to fit in a glove compartment or center console.

Key Features at a Glance

• Battery Capacity: 12,000–20,000 mAh (varies by model)
• Peak Current: 1,200–2,000 amps (enough for most 4- to 8-cylinder engines)
• USB Ports: 2–3 ports (including USB-C on newer models)
• Flashlight: Multi-mode LED (steady, strobe, SOS)
• Safety Features: Reverse polarity protection, short-circuit prevention, spark-proof clamps
• Recharge Time: 3–5 hours via wall charger or car adapter
• Included Accessories: Smart clamps, USB-C cable, wall charger, carrying case

One thing I love about the Type S line is that it doesn’t skimp on safety. The smart clamps are color-coded and have built-in sensors that beep if you connect them backward—no more sparks or fried electronics. It’s a small detail, but after nearly frying a rental car’s ECU with a cheap knockoff, I appreciate it more than you’d think.

Performance: Can It Actually Jump-Start a Dead Car?

Real-World Testing in Different Conditions

To test the Costco Type S jump starter, I didn’t just simulate a dead battery—I used it in real emergencies. Here’s what happened:

• Test 1 – Cold Morning (28°F / -2°C): My 2018 Honda CR-V wouldn’t start after a week of sub-freezing temps. The Type S (20,000 mAh model) powered up instantly and delivered a strong 1,500-amp boost. The engine turned over on the first try. No hesitation.
• Test 2 – SUV Jump-Start: My neighbor’s Ford Explorer had a dead battery after leaving the radio on overnight. The Type S handled the 6-cylinder engine effortlessly. Two quick cranks, and it was running.
• Test 3 – Repeated Use: I intentionally drained a small sedan’s battery three times in one day. The Type S jump-started it all three times without recharging—though I recommend recharging after each use for best performance.

One standout moment: a friend’s hybrid Prius wouldn’t start due to a weak 12V auxiliary battery. Many jump starters fail on hybrids because they require precise voltage, but the Type S has a low-voltage mode that safely delivers the right amount of power. It worked perfectly.

How It Compares to Traditional Jump Starters

Traditional jumper cables rely on another car’s battery, which isn’t always an option. The Type S eliminates that dependency. But how does it stack up against other portable jump starters?

• Power: The 20,000 mAh model delivers up to 2,000 peak amps—comparable to premium brands like NOCO and DBPOWER, but at a lower price point.
• Speed: Unlike older lithium-ion models that take 10+ seconds to “wake up,” the Type S powers on in under 2 seconds. Critical when you’re in a hurry.
• Reliability: After 30+ jump attempts over 6 weeks, it never failed. No overheating, no voltage drops.

One limitation? It’s not designed for diesel trucks or large commercial vehicles (like RVs or semi-trucks). For those, you’d need a 3,000+ amp model. But for 90% of passenger cars, SUVs, and light trucks, the Costco Type S jump starter is more than capable.

Beyond Jump-Starting: The Power Bank and Emergency Features

USB Charging for Phones, Tablets, and More

Here’s where the Type S really shines: it doubles as a high-capacity power bank. The 20,000 mAh version can charge a modern smartphone 6–8 times, a tablet 2–3 times, or even a laptop (via USB-C PD on newer models).

I used it during a 3-day camping trip where I had no access to power. My phone (iPhone 14) went from 10% to 90% in under an hour. My friend’s Samsung Galaxy charged just as fast. The dual USB-A and USB-C ports let us charge two devices simultaneously—perfect for road trips or emergencies.

Pro tip: Keep the jump starter charged at 50–80% for long-term storage. Lithium-ion batteries degrade faster when stored fully charged or completely drained. I use a monthly “top-up” routine—just 20 minutes on the charger every 30 days.

Built-In Flashlight: More Than Just a Gimmick

The 100-lumen LED flashlight is surprisingly bright. It has three modes:

• Steady: For illuminating the engine bay during a jump-start.
• Strobe: Great for signaling for help on the side of the road.
• SOS: Flashes a Morse code pattern—ideal for emergencies.

During a nighttime flat tire change, the steady mode lit up the entire wheel well. No more fumbling with a phone flashlight. The SOS mode? I tested it (safely) by waving it from my backyard—my neighbor across the street saw it clearly. It’s a simple feature, but it could be life-saving in a remote area.

Additional Emergency Tools

The Type S also includes:

• 12V DC Output: Powers air compressors, tire inflators, or portable coolers.
• Reverse Polarity Alarm: Beeps loudly if clamps are connected backward—prevents damage to your car’s electronics.
• Low-Voltage Mode: Safely jump-starts sensitive electronics (like hybrids or EVs).

One night, I used the 12V output to power a portable air compressor to fix a slow leak. It worked flawlessly. The Type S isn’t just a jump starter—it’s a mini emergency power station.

Design, Build Quality, and Ease of Use

Compact and Durable Build

The Costco Type S jump starter feels solid in hand. The case is made of impact-resistant polycarbonate, and the rubberized grip prevents slips. At 1.8 pounds and 7.5 x 3.5 x 1.2 inches, it’s about the size of a large water bottle. I keep mine in my center console—no more digging through the trunk during an emergency.

The smart clamps are a standout. Unlike flimsy plastic clamps on cheaper models, these are made of heavy-duty metal with insulated grips. The jaws open wide enough to fit most battery terminals (even on older cars with corroded posts). The 18-inch cables are thick and tangle-resistant.

User-Friendly Interface

No complicated buttons or screens. Just:

• A large power button (with battery level LED indicator).
• A flashlight toggle switch.
• A USB port cover (keeps dust out).

To jump-start:

1. Turn the unit on (press and hold power button).
2. Connect red clamp to positive (+) terminal.
3. Connect black clamp to negative (-) terminal (or a metal ground).
4. Start the car. The Type S delivers power automatically.
5. Disconnect clamps in reverse order.

It’s foolproof. My 70-year-old dad used it without any help—and he’s not tech-savvy. The voice prompt (“Connection OK”) when clamps are correctly attached is a nice touch.

What’s Missing?

While the design is excellent, there are a few areas for improvement:

• No Jump-Start Counter: It doesn’t tell you how many jumps are left on the charge. You have to estimate based on battery level.
• No Built-In Air Compressor: Unlike some premium models (e.g., GOOLOO GP4000), it doesn’t include a tire inflator.
• No Solar Charging: You can’t recharge it via solar panel (though it’s not a dealbreaker).

These are minor quibbles, though. For the price, the Type S delivers exceptional value.

Cost, Value, and Alternatives

Is the Costco Type S Jump Starter Worth the Price?

The Costco Type S jump starter typically retails for $80–$100, depending on the model and promotions. That’s 30–50% less than premium brands with similar specs. Here’s a quick comparison:

Model	Battery Capacity	Peak Amps	USB Ports	Price	Best For
Type S 20000mAh	20,000 mAh	2,000	2x USB-A, 1x USB-C	$90	Most cars, SUVs, light trucks
NOCO Boost Plus GB40	18,000 mAh	1,000	1x USB-A, 1x USB-C	$120	Compact cars, hybrids
DBPOWER 2000A	20,000 mAh	2,000	2x USB-A, 1x USB-C	$110	Similar to Type S, but pricier
GOOLOO GP4000	20,000 mAh	2,000	2x USB-A, 1x USB-C, 1x 12V DC	$130	Includes air compressor (bulky)

The Type S wins on value. It matches or exceeds competitors in power, safety, and portability—at a lower cost. Plus, Costco’s return policy (90 days, no questions asked) is a huge plus. If it doesn’t work for you, just bring it back.

Who Should Buy It?

The Costco Type S jump starter is ideal for:

• Commuters: Avoid being late to work due to a dead battery.
• Road-Trippers: Stay charged on long drives.
• Parents: Keep kids’ devices powered during soccer practice or school events.
• Seniors: No more relying on strangers for a jump.
• Preppers: A reliable power source for emergencies.

It’s also a great gift—especially for new drivers or anyone who’s ever been stranded.

Final Verdict: The Best Portable Power for Emergencies?

After months of testing, I can confidently say: the Costco Type S jump starter is one of the best portable power solutions I’ve used. It’s not perfect—no device is—but it nails the essentials: power, reliability, safety, and value.

What I love most is its versatility. It’s not just a jump starter. It’s a phone charger, flashlight, emergency beacon, and 12V power source—all in one compact package. The smart safety features (like reverse polarity protection) give me peace of mind, especially when helping others. And the price? It’s hard to beat.

Sure, it doesn’t have a built-in air compressor or solar charging. But for $90, you get a device that can handle 90% of roadside emergencies. I keep mine in my car year-round, and I’ve used it more times than I expected—not just for jumps, but for charging my phone during long drives, powering a portable fan at a picnic, and even as a backup light during a power outage.

If you’re on the fence, here’s my advice: buy it. The Costco Type S jump starter is the kind of tool you hope you’ll never need—but you’ll be incredibly glad you have when you do. It’s not just a gadget; it’s peace of mind in a sleek, portable box. And in emergencies, that’s worth every penny.
