Model RZ-300 

Never get stuck again! With the Rezervo Batteryless Jump Starter, it will be ready anytime, anywhere you need it. Unlike traditional jump starters that require a charge before jumping your car, the Rezervo Batteryless Jump Starter only requires a quick charge from your weak battery to get your car started.

• Designed for both the professionals and DIY users
• Simple and safe to use
• No batteries inside
• No need to wait hours to recharge
• Even starts vehicles without a battery.

• The REZERVO batteryless jump starter uses ultracapacitor technology. It is able to harness the power from your weak battery and boost it to start your car. With built-in intelligent circuitry designs, it also prevents you from making mistakes while using the jump starter.
  
  This jump starter performs well in extreme conditions. Traditional batteries, such as lead acid or lithium-ion, deliver lower cranking current at low temperatures. The ultracapacitors in our batteryless jump starter keep the same starting current even at extreme cold weather
