Why You Need a Reliable Jump Starter in Your Car

Picture this: It’s a cold winter morning, you’re running late for work, and you turn the key in your ignition—nothing. The engine doesn’t even click. You’re stranded, your phone’s battery is at 12%, and the nearest gas station is a mile away. This isn’t just a bad dream; it’s a real-life scenario that happens to thousands of drivers every year. A Costco Type S jump starter & power bank could be your lifeline in these moments. No more waiting for a kind stranger to give you a jump, no more calling roadside assistance and waiting 45 minutes in the freezing cold. With a compact, powerful device like this, you take control of your situation—anytime, anywhere.

But here’s the thing: not all jump starters are created equal. Some are too bulky, others don’t hold a charge, and many fail when you need them most. That’s why I decided to test the Costco Type S jump starter power bank—a popular choice among budget-conscious yet practical drivers. After using it through multiple seasons, from icy mornings to long road trips, I’m ready to share the real scoop. Whether you’re a daily commuter, a road tripper, or someone who just wants peace of mind, this review will help you decide if this device is the right fit for your emergency kit. And yes, we’ll talk about what it can do beyond jump-starting your car—because it’s also a full-fledged portable charger for emergencies.

What Is the Costco Type S Jump Starter & Power Bank?

More Than Just a Jump Starter

The Costco Type S jump starter power bank is a multi-functional device that combines a high-capacity lithium-ion battery with jump-starting capabilities, USB charging ports, and an LED flashlight. Unlike traditional jumper cables that require another vehicle, this device is completely self-contained. You charge it at home, keep it in your glove box, and use it to jump-start your car’s battery without needing help from anyone else.

It’s designed with everyday drivers in mind. Think of it as a Swiss Army knife for car emergencies. It’s compact enough to fit in your center console or trunk, yet powerful enough to start most gasoline engines up to 6.0L (and some smaller diesel engines). Plus, it doubles as a portable power bank, so you can charge your phone, tablet, or even a portable fan during a power outage.

Key Features at a Glance

• Jump-start capability: Up to 12V, 1500 peak amps (varies by model year)
• Battery capacity: 18,000–20,000 mAh (enough for 20+ phone charges)
• USB ports: Dual USB-A (5V/2.4A) and one USB-C (PD 18W fast charging)
• LED flashlight: 3 modes (steady, strobe, SOS)
• Reverse polarity protection: Prevents damage if clamps are connected incorrectly
• Smart safety features: Over-current, over-voltage, and short-circuit protection
• Weight: Around 2.2 lbs—light enough to carry, heavy enough to feel substantial

I’ve used mine to jump-start a 2018 Honda Civic with a completely dead battery, charge my iPhone 14 from 5% to 100% three times, and even power a small camping lantern during a blackout. It’s become a staple in my car emergency kit—and after seeing how well it performs, I think it should be in yours too.

Performance: How Well Does It Actually Work?

Jump-Starting in Real-World Conditions

Let’s get to the heart of the matter: can the Costco Type S jump starter & power bank actually start your car when the battery is dead? The answer is a resounding yes—but with a few caveats.

In my testing, I simulated a dead battery by leaving the car lights on overnight. The next morning, the car wouldn’t start. I connected the Type S clamps to the battery terminals (red to positive, black to negative), pressed the power button, and waited a few seconds. Then, I tried the ignition—and the engine roared to life on the first try. No hesitation, no sputtering. It was that simple.

I repeated this test three more times over different seasons:

• Winter (28°F): Started a 4-cylinder sedan with no issues.
• Summer (95°F): Worked on a minivan with a weak battery.
• Rainy day: Used it under light rain (with the device under the hood cover)—still worked.

One thing to note: the jump starter needs to be at least 50% charged to deliver reliable starts. I once tried using it at 30%, and it only managed a weak crank. After recharging to 75%, it started the same car without a problem. So, keep it charged—that’s the golden rule.

Power Bank Performance: Charging Phones, Tablets, and More

Beyond jump-starting, the Type S shines as a portable charger for emergencies. The 18,000–20,000 mAh battery is more than enough to charge most smartphones 2–3 times. I tested it with:

• iPhone 14: 3 full charges (from 5% to 100%)
• iPad Air: 1.5 charges (from 20% to 100%)
• Google Pixel 6: 2.5 charges

The USB-C port supports 18W Power Delivery, which means fast charging for compatible devices. My iPhone went from 10% to 50% in about 25 minutes. That’s not as fast as a wall charger, but it’s impressive for a portable device.

One cool feature: you can charge your phone while the jump starter is charging itself. I left it plugged into a wall outlet with my phone connected, and both charged simultaneously. This is great for overnight charging—no need to choose between your phone and the jump starter.

Flashlight and Safety Features

The built-in LED flashlight has three modes: steady (for general use), strobe (to attract attention), and SOS (flashing in a distress pattern). I used it during a nighttime tire change, and it lit up the undercarriage enough to see the lug nuts clearly. The beam isn’t super wide, but it’s bright and focused—perfect for emergencies.

Safety is a big selling point. The Type S has reverse polarity protection, which means if you accidentally connect the clamps backward, it won’t spark or damage the device. I tested this on purpose (don’t do this at home!) and the device simply displayed an error message and shut down the jump-start function. After reconnecting correctly, it worked fine.

It also has thermal sensors that shut it down if it gets too hot or cold. I left it in my car during a heatwave (110°F inside the cabin), and it automatically powered down until it cooled. That’s a smart safety net.

Design and Build Quality: Is It Built to Last?

Compact, Durable, and User-Friendly

The Costco Type S jump starter power bank has a rugged, no-nonsense design. It’s made of high-impact ABS plastic with rubberized side grips, so it doesn’t slip out of your hands—even when you’re wearing gloves in the winter.

Size-wise, it’s about the length of a large smartphone and slightly thicker than two stacked. It fits easily in a glove box, center console, or emergency kit. The included carrying case is a nice touch—it keeps the clamps and cables organized and protects the device from dust and scratches.

The clamps are heavy-duty copper with insulated handles. They’re not as bulky as traditional jumper cables, but they’re strong enough to grip battery terminals securely. I’ve used them on both side-terminal and top-post batteries without issues.

Interface and Ease of Use

The control panel is simple and intuitive. There’s a large power button, a battery level indicator (4 LED lights), and separate buttons for the flashlight and jump-start mode. No complicated menus or apps—just press and go.

One thing I appreciate: the device gives you a clear signal when it’s ready to jump-start. When you connect the clamps correctly, it beeps and lights up a green “Ready” indicator. If there’s a problem (like reversed polarity), it flashes red and beeps. This takes the guesswork out of the process.

The only minor downside? The screen is a bit dim in direct sunlight. I had to shade it with my hand to see the battery level during a midday jump-start. Not a dealbreaker, but worth noting.

Charging Time and Battery Retention

The Type S takes about 4–5 hours to fully charge using the included wall adapter. You can also charge it via USB-C from a laptop or power bank, though it’s slower (around 6–7 hours).

Battery retention is solid. I left mine unplugged for two months (with 80% charge), and it still had 65% when I checked. That’s good news for people who don’t use it often but want it ready when they do.

Pro tip: Charge it every 3–4 months to keep the battery healthy. Lithium-ion batteries degrade faster when left fully drained or fully charged for long periods.

Cost and Value: Is It Worth the Price?

How It Compares to Other Jump Starters

The Costco Type S jump starter & power bank typically retails for $79.99–$99.99 at Costco warehouses and online. That’s mid-range in the jump starter market. For comparison:

• Entry-level models (under $60): Often have lower peak amps, smaller batteries, and fewer safety features.
• High-end models ($120+): May offer higher cranking power, jump-starting for larger engines, or built-in air compressors.

But here’s the thing: the Type S strikes a great balance. It’s not the cheapest, but it’s far from the most expensive. And for most drivers, it offers just the right amount of power and features without overcomplicating things.

What You’re Really Paying For

When you buy the Type S, you’re not just paying for a battery. You’re paying for:

• Reliability: It works when you need it—no fluff, no gimmicks.
• Safety: Multiple protection systems prevent damage to your car or the device.
• Versatility: Jump starter, power bank, flashlight—all in one.
• Brand trust: Type S is a Costco-exclusive brand known for quality control.

I’ve seen cheaper jump starters fail after a few uses. The Type S has been through 8 jump-starts and dozens of phone charges in 14 months—and it still works like new. That’s value.

Costco Perks: The Hidden Bonus

One big advantage of buying the Type S at Costco? The return policy. If you’re not happy with it—even after months of use—you can return it for a full refund. No questions asked. That’s peace of mind you won’t get from most online retailers.

Plus, Costco often runs member-exclusive discounts. I got mine for $69.99 during a holiday sale. Keep an eye out for those deals!

Who Should Buy the Costco Type S Jump Starter?

Ideal Users and Use Cases

The Costco Type S jump starter power bank is perfect for:

• Daily commuters: If you drive to work every day, a dead battery can ruin your schedule. This device gets you back on the road fast.
• Road trippers: Long drives mean more chances of battery failure. Keep it in your trunk for peace of mind.
• Elderly drivers: No more relying on strangers for a jump. It’s easy to use, even for seniors.
• Emergency preparedness kits: Great for home, car, or camping gear. Use it during power outages or natural disasters.
• Tech-savvy drivers: If you rely on your phone for navigation, music, or work, the power bank feature is a game-changer.

When It Might Not Be the Best Fit

That said, it’s not for everyone:

• Heavy-duty truck or diesel owners: If you drive a big diesel pickup, you may need a higher-amp model (2000+ amps).
• People who rarely drive: If your car sits for weeks, you might forget to charge the jump starter. Consider a model with a built-in solar charger.
• Minimalists: If you only want a power bank, you can find cheaper options. But if you want both jump-starting and charging, the Type S is a great combo.

Real-Life Scenarios Where It Shines

Here are a few examples from my own experience:

• Dead battery in a parking garage: No other cars nearby. Used the Type S to jump-start and drove straight to the mechanic.
• Phone died during a hike: Charged my phone from 3% to 80% using the jump starter in my backpack.
• Power outage at home: Used the flashlight and powered a small fan for 2 hours while waiting for the grid to come back.

After months of real-world use, I can confidently say the Costco Type S jump starter power bank is one of the best all-in-one emergency tools for drivers. It’s reliable, easy to use, and packed with features that go beyond just jump-starting.

Is it perfect? No. The screen could be brighter, and it’s not ideal for huge diesel trucks. But for the average car owner, it’s a smart, practical investment. You’re not just buying a gadget—you’re buying peace of mind. The kind that says, “No matter what happens, I’ve got this.”

Whether you’re dealing with a dead battery, a dead phone, or a power outage, this device has your back. And at under $100, it’s a small price to pay for independence and preparedness.

So, if you’re on the fence: go for it. Pick one up the next time you’re at Costco. Toss it in your car, charge it every few months, and forget about it—until you need it. Because when you do, you’ll be glad you have it.

Stay safe, stay charged, and never get stranded again.
