Review on πŸ”‹ Rezervo Batteryless Jump Starter - Ultracapacitor Technology - Jumpstart Vehicles (RZ-550 (550A)) by Sfl Richardson

Works great!

He could jump over my friend's old Toyota Truck 97. He survived the winter. The battery was about 7 volts when I connected the batteryless jumper block. First I cleaned the clamps. They were dirty. Then the red error light came on. Reset failed error. So I took the cigarette lighter adapter (which is included) and charged the battery in my car. It took about 2 minutes to get 14 volts. I put it back in my buddy's truck, got the green light. His truck started right away! I highly recommend this device.

Pros
