Cardiac Science G3 AED - Encore Series (Refurbished)

Cardiac Science Powerheart G3 Refurbished, Encore Series™

Proven Reliability, Built for Everyday Responders

The Powerheart G3 Refurbished Encore Series™ is one of the most widely deployed AEDs in schools, facilities, and public spaces across the country. Professionally refurbished and restored to full function, it pairs guided, voice-coached operation with smart energy delivery, so an untrained bystander can respond with confidence in the moments that matter most. This is the everyday-rescuer version of the G3: no manual overrides, no professional-mode complexity. Just clear coaching and a device ready to act.

Available in both semi-automatic and fully automatic models. The semi-automatic prompts the responder to press the shock button when a shock is advised. The fully automatic delivers the shock on its own after a clear verbal countdown. Both are guided start to finish. NOTE: This model is no longer being made by the OEM, so support is limited.

One-Touch Activation with Lift-Up Lid Design

Guided response from the first second:

• Lift-up lid powers the unit on automatically, no separate power button to find
• Voice instructions begin the moment the lid opens
• Clear, calm coaching walks any responder through each step
• Fast deployment when seconds decide the outcome
• Simple operation reduces hesitation under stress

Rescue Ready® Self-Testing

Confidence the device will work before you ever need it:

• Automated daily self-check of battery, hardware, software, and electrode pads
• Weekly partial charge and monthly full charge of the high-voltage electronics
• Rescue Ready indicator confirms the unit is prepared at a glance
• Reduces the risk of an unnoticed failure between inspections

STAR® Biphasic Technology, Treatment Matched to the Patient

Smart energy delivery:

• Measures patient impedance through the electrode pads
• Customizes each shock to the individual patient’s physiology
• Delivers an optimized energy level rather than a one-size-fits-all dose
• Consistent, patient-specific therapy in a portable, easy-to-use format

Escalating Energy Protocol

Progressive treatment when the first shock is not enough:

• Delivers escalating variable energy on a 200-300-300 joule protocol
• Automatically increases energy on successive shocks if earlier ones are not effective
• Impedance-compensated delivery for each patient
• Built to align with recognized resuscitation guidelines
