Perfect small device. Cable long enough to charge car battery from driver seat. Charge started by 100W going to 65W later on and finally 15W. I used a River Pro (first generation) to supply the required power.

If you don't have a car battery charger and you own an EcoFlow generator, this is perfect. It will not jump start your car, but within 20 minutes you should have enough charge on the battery to start the car. It is perfect for people who don't use a car and want to charge the battery without driving the car for 1/2 hour. It is also very small so if you do have your generator with you while on vacation and your battery goes dead, you are not stranded. Unfortunately, there ar no instructions in English on how to use it, so be sure to read the instructions on the website.
