Can I Jumpstart a Dead Battery with a Power Bank?
If you’ve ever found yourself stranded with a dead car battery, you know how frustrating it can be. I remember one morning when I was rushing to work, only to find that my car wouldn’t start. The dashboard lights flickered, but the engine refused to turn over. After a quick check, I realized the battery was completely drained. Stuck in the middle of nowhere, I thought, “What now?” I had no jumper cables, no one around to help, and the thought of waiting for roadside assistance made me cringe. That’s when I remembered I had a portable power bank in my bag. It wasn’t just any power bank—it was one that advertised it could jumpstart a car battery. I had never used it before, so I wasn’t sure if it would work. But I was desperate.
This moment made me wonder—can a portable power bank really jumpstart a car’s dead battery? After doing some research and diving into my experience, I realized that the answer is yes—under certain circumstances. A jumpstarter power bank, also known as a portable car jump starter, can indeed provide enough power to get your car running again. But, like anything, there are certain things you need to know before you attempt it. In this article, I’ll guide you through the process of using a power bank to jumpstart a dead car battery, share some tips based on my own experience, and explain when it’s better to call for help.

1. What Is a Jumpstarter Power Bank?
Before diving into how to use a power bank to jumpstart your car, it's important to understand what a jumpstarter power bank is and how it works. A jumpstarter power bank is a compact, portable device designed to jumpstart your vehicle's dead battery without the need for another car or jumper cables. These devices are typically equipped with a high-capacity lithium battery and jumper cables that can be attached directly to your car’s battery terminals.
I remember when I first heard about jumpstarter power banks. I thought it was just another gadget, but then I came across one that was highly recommended by others in the automotive community. After reading several positive reviews, I decided to invest in one for emergencies, and I haven’t regretted it. In fact, when I was stranded with my dead battery, my portable power bank was a lifesaver.
These power banks come with a variety of features such as built-in safety protections to prevent overheating, overcharging, and short circuits. Many models also offer additional functions, such as USB ports to charge your phone or laptop and built-in LED flashlights for emergency situations. While these devices are incredibly convenient, it’s important to note that they aren’t a permanent solution for a dead battery—they are meant to give you a temporary boost until you can get your battery properly charged or replaced.

2. Can a Power Bank Jumpstart a Dead Car Battery?
The short answer is yes, but with some important considerations. In my own experience, I was able to use my power bank to jumpstart my car, but it only worked because my battery wasn’t completely fried—it just had a low charge. If your car battery is too far gone, no power bank will be able to jumpstart it.
A power bank can provide the necessary power to get your car’s engine cranking again, but it’s crucial to know that these devices are designed for low-charge batteries. Most power bank jump starters have a peak current rating that ranges between 300 to 1000 amps, depending on the model. If your car’s battery is significantly damaged or totally discharged, the power bank may not be able to provide enough power. I had a similar situation where the battery was just drained, and after connecting the jumper cables from the power bank, my car started up in less than a minute.
If you’re not sure whether your battery can still hold a charge, you can test it by attempting to jumpstart it with the power bank. However, if you notice that your car isn’t responding after several attempts, it may be time to call for professional help or arrange for a tow. In my case, I used the power bank to get enough juice into the battery, allowing me to drive to the nearest service station for a full recharge.
3. How to Jumpstart Your Car Using a Power Bank
Once you’ve confirmed that your car’s battery is low but still salvageable, the next step is to jumpstart it using the power bank. Here’s how I went about it during my own experience:
- Step 1: Safety First - Before you begin, make sure you are in a safe location. If you’re on the side of the road, turn on your hazard lights and keep a safe distance from traffic. Make sure the power bank is fully charged and ready to use.
- Step 2: Attach the Jumper Cables - Most power bank jump starters come with built-in jumper cables. Connect the red (positive) clamp to the positive terminal of your car battery and the black (negative) clamp to a grounded metal part of the car (usually a bolt or a metal part of the engine). Never attach the black clamp to the negative terminal of the battery, as this can cause sparks.
- Step 3: Power On the Jump Starter - Turn on your power bank and make sure it’s providing power to your car’s battery. Some models may have an indicator light showing that it’s working. Wait a few seconds to let the power bank charge the battery slightly.
- Step 4: Start the Car - Once the power bank is connected and charging the battery, turn your car’s ignition key. In my case, it only took a few seconds before the engine started, and I was able to drive away. If your car doesn’t start after a few tries, give it a minute and then try again. If there’s still no response, your battery may need to be replaced.
- Step 5: Disconnect and Recharge - Once your car starts, disconnect the jumper cables, starting with the black (negative) clamp, followed by the red (positive) clamp. Keep the car running for a while to allow the alternator to charge the battery further. If your car is still having trouble starting, it’s best to seek professional assistance or arrange for a battery replacement.
It’s important to note that jumpstarting your car with a power bank is a temporary solution. While it works great for giving you enough power to get to a service center or repair shop, the best course of action is to have your battery tested and replaced if necessary.
4. When to Call a Professional
There are situations where you should consider calling a towing service or a professional mechanic for help, especially if your car doesn’t start even after using a power bank. Here are some scenarios when it’s time to seek professional help:
- Repeated Jumpstarting Attempts Fail: If your car consistently fails to start despite multiple attempts with the power bank, the issue could be with the battery itself, or there could be an issue with the car’s electrical system. At this point, a mechanic should inspect the vehicle.
- Car Won’t Hold a Charge: If you notice that the car stops running shortly after being jumpstarted, it’s a sign that the battery might no longer be able to hold a charge. A professional will need to assess whether a battery replacement is required.
- No Power at All: If the power bank doesn’t seem to work or the car doesn’t respond at all, it’s possible that there’s a more serious problem, such as a blown fuse or an issue with the alternator. Calling a professional mechanic can help you identify the problem and avoid further damage.
If you ever find yourself in a situation where jumpstarting with a power bank isn’t enough, consider contacting a trusted towing service like Rescue & Towing. They offer quick, reliable towing services and can help you get your car to the nearest repair shop for further assistance.
5. Benefits of Having a Jump Starter Power Bank
Over the years, I’ve come to rely on my jumpstarter power bank for emergencies. It’s compact, portable, and easy to store in my car. The peace of mind that comes from knowing I can get my car started with just a few steps is invaluable, especially on long trips or when I’m in an unfamiliar area. If you’re thinking about purchasing a jumpstarter power bank, I highly recommend it. They’re relatively affordable and can save you a lot of time and stress in case of an emergency.
