The ZOLL AED 3 launched as the spiritual successor to the AED Plus — same core architecture, Wi-Fi connectivity, full-color rescue screen, and a unified Uni-padz pad set that works for both adults and children. The retail premium is roughly $400 ($2,199 vs $1,799). For most buyers, the question reduces to whether the color screen and Wi-Fi feature set justify the price gap.
Both share the foundational ZOLL value proposition: Real CPR Help® real-time compression depth and rate coaching, the industry’s longest pad shelf life (5 years on the AED Plus’s CPR-D-padz, 5 years on the AED 3’s Uni-padz), and 5-year battery cycles.
Quick answerBuy the AED Plus for single-AED budget buyers, simple offices, and any facility that does not need Wi-Fi remote monitoring or pediatric capability from a unified pad set. Buy the AED 3 for fleet programs (5+ units), mixed adult-and-pediatric environments, facilities with central program management, and gyms wanting the color rescue display.

The Uni-padz pediatric advantage
The AED Plus uses two separate pad sets: standard CPR-D-padz for adults, and Pedi-padz II for pediatric. The pads are not interchangeable — the rescuer must physically swap pad sets during a pediatric rescue. For mixed-population facilities (schools, family fitness centers, places of worship), this is operational overhead and a documented failure point under rescue stress.
The AED 3 uses ZOLL’s Uni-padz: one universal pad set that works for both adults and children. For pediatric rescue, the rescuer applies the same pads in modified placement (one front, one back) per the device’s screen instructions. The device adjusts shock energy automatically. No swap workflow. No separate cartridge to track.
For facilities with potential pediatric rescue, the Uni-padz architecture is a meaningful workflow improvement.
The Wi-Fi fleet management value
The AED 3 includes Wi-Fi connectivity for integration with ZOLL PlusTrac — a centralized fleet management platform that monitors device status, tracks pad and battery expiration, alerts on failed self-tests, and provides post-event ECG data download. For organizations managing 5+ AEDs, PlusTrac removes a manual tracking burden that defaults to “miss it until you need it.”
For single-AED programs and small businesses, the Wi-Fi feature is unused. Most don’t have the IT infrastructure to integrate, and program scale doesn’t justify the platform overhead.
Rescue screen UX
The AED 3’s full-color screen displays large-icon rescue instructions, real-time CPR feedback metrics (depth bar, rate timer), and post-shock status. The AED Plus uses text + status icons — clear but less visually rich.
For high-turnover environments and lay-public deployments, the color screen matters. For trained-team environments where the rescuer is already familiar with AED workflow, the difference is marginal.
Real-world deployment scenarios
Scenario A — 12,000 sq ft commercial gym, 1 AED, adult members only
Trained staff (personal trainers, front desk). High SCA risk during exertion. Single AED program. Recommendation: ZOLL AED Plus. Real CPR Help® is the priority — and present on both devices. $400 saving funds for CPR training renewals for 8 staff. No pediatric requirement. No fleet management needed.
Scenario B — 5-school K-12 district, 12 AEDs total, central facilities management
Mixed adult + pediatric. Central program coordinator. Annual compliance reporting required. Recommendation: ZOLL AED 3. Uni-padz removes the pediatric swap workflow across all schools. PlusTrac centralizes expiration tracking and self-test monitoring across the fleet. The $400 premium per device is justified by district-level operational savings.

Verdict by buyer profile
Single-AED · Adult-Only · Budget-First
ZOLL AED Plus
Real CPR Help® at the lower price point. Same 5-year consumables advantage. The right pick when neither pediatric nor fleet management features are needed.
Fleet Program · School District · Mixed-Age · Compliance-Heavy
ZOLL AED 3
Uni-padz removes the pediatric swap workflow. PlusTrac centralizes fleet monitoring. Color screen + lighter weight + 8-year warranty round out the premium positioning.
Frequently asked questions
Do both have Real CPR Help®?
Yes. The depth + rate coaching is present on both devices and is the ZOLL differentiator vs Philips and HeartSine.
Is the AED 3 worth $400 over the AED Plus?
For fleet programs and mixed-age facilities, yes — the Uni-padz alone justifies it. For single-AED adult-only deployments, no.
Can both be used on children?
Yes. The AED 3 uses Uni-padz that work for both adults and pediatrics. The AED Plus requires a separate Pedi-padz II for pediatric use.
Does the AED Plus support PlusTrac?
No. Wi-Fi connectivity is exclusive to the AED 3 in the ZOLL consumer-class line.
Are rechargeable batteries an advantage?
For fleet programs with central management, yes — fewer cells to track and dispose of. For single-AED programs, the difference is operational rather than economic.
Are both FDA-cleared in 2026?
Yes. Both hold active 510(k) clearance.
