They can provide 400 to 2000 amps of power, which is enough to get your car running again, even if the battery is almost dead.
The best part is that they’re compact and easy to carry, making them perfect for emergencies when you’re on the road or in a place without other cars nearby. Check out our guide on the 4-in-1 jump starter with air compressor for a reliable solution.

Charging Your Car Battery with Solar Power
What is Solar Charging?
Solar chargers turn sunlight into electricity to charge your car battery. You can find chargers that range from 5 watts (slower charging) to 20 watts (faster charging). A 5-watt solar charger works best for keeping your battery topped off, while a 20-watt charger can give your battery a faster boost when you’re in a pinch. Learn more in our guide on the best solar car battery chargers.
How Long Will It Take?
The time it takes to charge your battery depends on the charger’s wattage and how much sunlight it gets. If you’re exploring how to charge a car battery without an AC outlet, a solar charger can be a great solution. For example, a 20-watt charger can give you about 30-40% charge after 4-6 hours of direct sunlight. While this isn’t super fast, it’s a great option for slowly recharging or maintaining your battery over time, especially when you’re camping or road-tripping.
Choosing the Right Solar Charger
If you need to charge your battery faster, go for a 20-watt charger. It’s perfect for recharging a bit quicker or handling larger batteries. If you just need to maintain your battery’s charge while on the go, a 5-watt charger will work fine. Solar chargers are super useful for outdoor adventures, as long as you’re in a sunny spot.
Jump Starting with Another Vehicle
How to Use Jumper Cables
Jump-starting your car with another vehicle is a fast way to get your battery charged. Here’s a simple step-by-step guide: Learn more in our guide on how to use jumper cables to start a dead vehicle.
- Park the two cars close enough so the jumper cables can reach both batteries.
- First, attach the red clamp to the positive (+) terminal of your dead battery, then attach the other red clamp to the positive (+) terminal of the working battery.
- Next, attach the black clamp to the negative (-) terminal of the working battery, and the other black clamp to a metal part of your car away from the battery (this helps ground it).
- Start the working car and let it run for 5-10 minutes to charge your dead battery a little. Then, try starting your car.
Safety Tips to Keep in Mind
While jump-starting is easy, safety is important:
- Make sure the jumper cables don’t touch each other while they’re attached to the batteries, as this can cause sparks.
- Always ensure both cars are off before connecting the cables, and only start the working car once everything is hooked up properly.
- If your battery is below 12 volts or has been acting up, jump-starting may only work temporarily. Afterward, you should have your battery checked or replaced.

When your car battery dies and you don’t have an AC outlet nearby, don’t panic! You’ve got options to charge a car battery without an AC outlet. A portable jump starter, solar charger, or jump-starting from another car can all help get your vehicle back up and running.
I’ve found portable jump starters to be a lifesaver during road trips, while solar chargers are great for keeping my battery topped off when I’m camping.Just remember, these methods won’t fully charge a battery in bad condition, but they’ll definitely help you get back on the road.
