If you’ve ever been stranded with a dead battery, you already know the value of a reliable jump starter. But what if that same device could charge your phone or laptop too? That’s where the power bank feature comes in—a modern necessity that’s turning jump starters into smart, multi-use tools. At Tow Mates, we’ve seen firsthand how valuable this dual function is for drivers, mechanics, and even everyday users.
In this guide, we’ll explore the features, real-world use cases, and what to look for before choosing a jump starter with power bank feature.
Why a Power Bank Feature Is More Than a Bonus
The power bank feature isn’t just an add-on — it’s a critical part of how jump starters have evolved. You’re no longer limited to just jump-starting your car. Need to charge a laptop or power your USB-C phone during a blackout? This device has you covered.
Some models, like those from NOCO or Gooloo, offer up to 20,000mAh capacity. That means you can charge several devices on a single charge.
Understanding How It Works
Built-in Battery System
At the core is a rechargeable battery that stores enough energy to jump a car and still power smaller gadgets. Amperage and voltage are balanced to safely handle multiple uses.
- Voltage: Most jump starters support 12V systems.
- Amps: Look for high peak amps, especially if you’re jump-starting diesel engines.
- Capacity: Measured in mAh (milliamp hours), this tells you how long it can power your devices.
Smart USB Ports
A proper jump starter with power bank feature will include USB-A and USB-C ports. USB-C fast charging is essential for phones and tablets. Some models even support charging laptops with up to 60W output.
Key Components to Look For
Jumper Cables
Heavy-duty, well-insulated jumper cables are a must. Cheap cables could cause polarity issues or overheat.
Clear Buttons and Indicators
You’ll want an easy-to-use button layout, with LED indicators showing battery levels and status. Some include a flashlight, which comes in handy during night emergencies.
Polarity Protection
Avoid serious mistakes by choosing models that offer reverse polarity protection. This prevents damage when cables are connected the wrong way.
Tow Mates Advice: Match the Device to the Job
It’s tempting to grab the biggest, most expensive starter you see on Amazon, but that’s not always necessary. Ask yourself:
- Do I drive a diesel or petrol car?
- How many devices will I charge regularly?
- Do I need a built-in air compressor for tires?
Matching features to your actual use case avoids overpaying and underperforming.
Real-World Performance (And What Users Say)
We’ve heard from plenty of Tow Mates customers who appreciate the real-world utility of this feature. One buyer noted how their jump starter powered their laptop during a camping trip. Another used the USB-C port to charge a dying phone while waiting for help on the side of the road.
These aren’t just gadgets for “car geeks.” They’re practical tools for daily life.
Brand Shoutouts: Trusted Names in the Market
Some of the most trusted brands include:
- NOCO Boost: Known for its tough exterior and strong amps.
- Tacklife: Offers useful extras like tire inflators.
- Fanttik: Excellent build quality and USB-C support.
Each of these comes with a solid user manual, making setup easy even for beginners.
Why Amperage Matters
Amps are what make or break a jump starter. Higher cranking amps mean better starting power, especially in cold weather.
- For small cars: 400–600 amps
- For SUVs/trucks: 800–1000+ amps
And if you’re powering laptops or multiple phones, make sure your jump starter has enough battery (in mAh) and amperage to keep up.
Our Final Thoughts on the Power Bank Feature
A jump starter with power bank feature isn’t just convenient — it’s smart. Whether you’re on a road trip, facing a breakdown, or just need to juice up a phone, it’s a tool you’ll be glad to have.
Tow Mates recommends investing in a unit that includes the essentials: strong battery, USB-C port, durable jumper cables, and solid polarity protection. Don’t fall for gimmicks — stick with trusted brands, check real reviews, and look for clear specifications on amperage and voltage.
Quick Buyer Checklist
- Has a USB-C output
- Offers 800+ peak amps

One More Thing: Don’t Skip the Manual
This might sound basic, but reading the user manual makes a big difference. Every model is slightly different. Learn what every button does, how long to charge it, and when to stop. Skipping this step is the top reason why users misuse their power bank feature.
