JUMP STARTER BOOST A BIG TRUCK
Car jump starter test: Clamp the clip on both ends of the battery, then start the truck (12V), the truck starts normally.
SWITCH & PUMP UP WITH TRUCK
The first test of the air pump: the tire is marked as 81psi, and the actual pressure is 96psi. We set the tire pressure to 75psi, set the target value to 95.5psi (100psi max), start the inflation, and complete it in 5 minutes. JFEGWO MAX automatically shuts down and uses the built-in power supply.
The second test of the air pump: the tire is completely deflated, JFEGWO MAX is fully charged, the built-in power supply is used, and the inflation starts. When inflated to 90psi, the USB port of MAX starts to smoke and MAX stops working
1. Our new jump starter JFEGWO MAX is very powerful and can be used for all 12V equipment such as cars, motorboats, motorcycles, lawn mowers, RVs, trucks and so on.
2. JFEGWO MAX can't fully inflate the tires of large trucks, but the car is completely fine.
3. JFEGWO MAX will automatically stop working when the internal temperature of the device exceeds 100 degrees Celsius(protective measures). Please stop the device for at least 5 minutes before continuing to use it.
