ZOLL AED Plus, Philips OnSite, or LIFEPAK CR2: which defibrillator should you choose?

Oct 13, 2026

Are you hesitating between the ZOLL AED Plus, the Philips HeartStart OnSite, and the LIFEPAK CR2?

These are three well-established defibrillators on the market, but their features are different enough to influence your decision.

The Philips focuses particularly on simple and intuitive use. The ZOLL distinguishes itself with its chest compression assistance. As for the LIFEPAK CR2, it notably offers an integrated child mode and, depending on the version, connectivity features.

So, which one is really worth it for your business?

Let’s compare them based on real-life situations rather than just listing their technical specifications.

Why choose the ZOLL AED Plus?

The ZOLL AED Plus has a unique feature worth noting: its Real CPR Help technology.

When a person performs CPR with the compatible electrodes, the device can tell them if they need to press harder and help them maintain an appropriate compression rate.

This is a tangible benefit.

Even after training, it can be difficult to know if compressions are deep enough when facing a real emergency.

The ZOLL AED Plus therefore provides extra assistance at that precise moment.

Another interesting element: its CPR-D-padz electrodes and batteries have an advertised shelf life of up to five years, depending on the manufacturer's conditions.

What we like: feedback on compression quality and long-life consumables.

What to consider: pediatric intervention requires separate compatible electrodes, and the device does not have the integrated connectivity features of certain CR2 versions.

For whom? Organizations that wish to provide more advanced support to those called upon to perform CPR.

Why choose the Philips HeartStart OnSite?

The Philips OnSite favors a simple approach.

When you open the device and activate it, voice prompts guide the user step-by-step.

There is no need to navigate complex menus or know how the defibrillator works beforehand.

This simplicity can be reassuring in a small business, shop, or office where employees are not necessarily used to intervening in an emergency situation.

This does not mean it lacks features, but rather that its operation is designed to be easy to understand.

What we like: its clear instructions and intuitive operation.

What to consider: unlike the ZOLL AED Plus, it does not directly measure compression depth to provide equivalent feedback. Pediatric use also requires specific electrodes.

For whom? Businesses looking above all for an AED that is simple to use, with no particular need for connectivity.

Why choose the LIFEPAK CR2?

The LIFEPAK CR2 deserves special attention if your organization hosts children or has multiple locations.

First, its integrated child mode allows for pediatric intervention without having to replace electrodes to switch from adult to child mode.

Second, some versions are available with Wi-Fi or cellular connectivity.

Take an organization with ten branches, each with its own AED. Rather than relying solely on checks performed in each establishment, a compatible monitoring system can facilitate remote tracking of the status of the devices.

You must, of course, plan for the system configuration and verify the terms of the connected service.

What we like: the integrated child mode and remote monitoring capabilities.

What to consider: not all versions offer the same connectivity. Tracking features must therefore be verified when choosing the configuration.

For whom? Facilities welcoming audiences of different ages and organizations that wish to simplify the tracking of multiple AEDs.

Which one is easiest to use without training?

All three devices are designed to guide laypeople during an intervention.

It would be difficult, however, to claim that one model is universally simpler than the other two.

The Philips OnSite stands out for its intuitive operation. The ZOLL AED Plus adds chest compression assistance. The LIFEPAK CR2 also offers voice guidance and different features depending on its configuration.

A demonstration of the devices can be particularly useful to distinguish between them.

And regardless of the chosen model, training in CPR and AED use remains highly recommended.

Which defibrillator is the cheapest to maintain?

You must compare the prices of electrodes and batteries, but also their replacement frequency.

The ZOLL AED Plus features consumables designed for a shelf life of up to five years.

For the other devices, intervals and costs vary according to components and configurations.

For example, a model cheaper to purchase could require more spending on consumables over several years.

The best approach is to request a comparison of the total cost over five years, including necessary accessories, planned replacements, and maintenance.

These recommendations serve as a starting point, not an absolute ranking.

For example, the Philips can be perfectly suitable for a sports environment, and the ZOLL can be an excellent choice in an office.

The best way to decide remains to compare the exact versions, necessary accessories, and long-term costs.
