A portable power station turns your car into a mobile office, a camp kitchen or a roadside lifeline. You can charge laptops and tablets on a long drive, keep a 12V cooler running, power camp lights and a fan when you stop for the night, and recharge your phone in an emergency. The best units for a car are compact, secure in a trunk or footwell and able to recharge from the car’s 12V outlet. Here are five of the best portable power stations for a car, plus a guide to charging them from your vehicle and using them safely.

What Can You Run from a Car Power Station?
List what you want to power, then check each device’s running watts. Typical examples:
| Device | Typical running power |
|---|---|
| Phone or tablet charging | 5 to 20W |
| Laptop | 50 to 90W |
| LED camp lights | 5 to 20W |
| Fan | 20 to 60W |
| Portable 12V fridge or electric cooler (average draw) | 40 to 100W |
| 12V tire inflator | About 100 to 150W |
| E-bike battery charger | 100 to 500W |
| Camping stove or kettle | 1000W or more (not recommended) |
A power station can also keep a CPAP, camera batteries or a drone charging on the road. Heating appliances use a lot of power, so they are best left to a stove or the car’s own systems.
Rough runtime on a road trip
Use this formula: hours = capacity (Wh) x 0.85 / device watts. The 0.85 allows for energy lost in the inverter. Here are estimates for two example setups: about 60W (a laptop and phones) and about 100W (a laptop, phones and a cooler):
| Power Station | About 60W | About 100W |
|---|---|---|
| EcoFlow RIVER 3 (245Wh) | About 3.5 hours | About 2 hours |
| Jackery Explorer 300 Plus (288Wh) | About 4 hours | About 2.4 hours |
| EcoFlow RIVER 2 Pro (768Wh) | About 11 hours | About 6.5 hours |
| Anker SOLIX C1000 Gen 2 (1024Wh) | About 14.5 hours | About 8.7 hours |
| Jackery Explorer 1000 v2 (1070Wh) | About 15 hours | About 9 hours |
These are estimates, not guarantees. Real runtime depends on the temperature, the age of the battery and how efficiently your devices run.
Charging a Power Station from Your Car
Most power stations can recharge from a car’s 12V outlet (the cigarette lighter socket) with a car charging cable. It is handy on road trips, but it is slow.
A typical 12V outlet delivers about 100 to 120W at most, limited by the car’s fuse. Estimate charging time with this formula: hours = capacity (Wh) / (charging watts x 0.85). At about 100W:
| Power Station | Rough charge time at about 100W |
|---|---|
| EcoFlow RIVER 3 (245Wh) | About 3 hours |
| Jackery Explorer 300 Plus (288Wh) | About 3.5 hours |
| EcoFlow RIVER 2 Pro (768Wh) | About 9 hours |
| Anker SOLIX C1000 Gen 2 (1024Wh) | About 12 hours |
| Jackery Explorer 1000 v2 (1070Wh) | About 12.5 hours |
These are rough estimates. Some units support faster car charging with a higher-power cable or an alternator charger, so check each model’s maximum car input and the accessories it supports.
Car charging tips:
- Charge only while the engine is running. Charging with the engine off can drain the car’s starter battery.
- Use the cable that comes with your power station, and plug it straight into the car’s 12V outlet.
- Check the fuse rating of your car’s outlet. Do not exceed it.
- Charge from a wall outlet before you leave, so the car only needs to top up.
- Fast wall charging at the hotel or campsite is much quicker than car charging.
How to Choose a Power Station for a Car
1. Choose a size you can carry. Units range from about 8 pounds to about 27 pounds. If you will move it often, lighter is better.
2. Match capacity to your trip. For phones and a laptop, 250 to 300Wh is enough. For a fridge, fan or overnight car camping, look at 700 to 1000Wh.
3. Check the car charging input. Make sure the unit accepts 12V input, and check how fast it can charge from the car.
4. Look for LiFePO4 batteries. They are known for long cycle life and good safety, which suits a unit that will travel with you.
5. Check the outputs. USB-C, USB-A, 12V and AC outlets let you run phones, laptops and small appliances without extra adapters.
6. Think about heat. Cars get very hot. Choose a unit with a stated operating temperature range, and plan to keep it out of the sun.
7. Consider noise and vibration. Quiet fans matter in a small cabin, and a good case or strap helps keep the unit from moving.

Safety Tips for Using a Power Station in a Car
- Secure it. Strap the unit down or wedge it in a footwell or trunk so it cannot fly around in a sudden stop. Do not leave it loose on a seat.
- Beware of heat. Do not leave a power station in a hot, parked car. High temperatures shorten battery life, and every unit has a stated operating and storage range. Check yours.
- Keep it ventilated. Do not cover the vents while it is running or charging.
- Keep it dry. Keep it away from spills, rain and wet gear.
- Do not use it as a jump starter unless the product is specifically designed and listed for jump-starting. Most power stations are not.
- Mind the cables. Keep cords away from pedals, seatbelts and the driver’s feet.
- Do not drain the starter battery. Charge from the car’s 12V outlet only while the engine is running.
- Follow the manual. Check the manufacturer’s guidance on car charging, temperature range and storage.
