For most Irish drivers, portable EV chargers aren’t worth the investment. A fixed home charger is faster, safer, and more reliable. While portable chargers can be handy in rare cases, they’re not a substitute for a proper installation.
What Are Portable EV Chargers?
Portable EV chargers (sometimes called “granny chargers”) are compact charging cables that plug directly into a standard three-pin household socket. They allow you to top up your EV battery anywhere with access to a plug. Whether at home, a friend’s house, or a holiday rental.
They’re designed for convenience, offering flexibility in places where dedicated chargers aren’t available. But this convenience comes with trade-offs in speed, safety, and long-term practicality.
Advantages of Portable EV Chargers
- Convenience: You can carry them in your boot and plug in almost anywhere with a standard outlet.
- Backup Option: Useful for emergencies or short top-ups when you can’t reach a public charger.
- No Installation Needed: They work right out of the box, no electrician or wall-mount required.
Why Portable Chargers Aren’t Ideal for Regular Use
Despite their appeal, portable chargers have significant limitations:
- Very Slow Charging: Standard sockets supply only 2.3 kW, meaning it can take over 24 hours to fully charge a medium-sized EV battery.
- Safety Risks: Prolonged high-current draw can overheat household sockets not designed for continuous EV charging.
- Not Weatherproof: Most portable chargers aren’t suitable for outdoor use in Ireland’s wet conditions.
- Limited Efficiency: Fixed wall chargers are safer, faster (up to 7.4 kW), and can be connected to solar systems for free charging.
The Better Choice: Fixed Home Chargers
Installing a dedicated smart EV home charger, like those offered by WattCharger is the best long-term solution for Irish drivers.
They provide:
- Fast, reliable charging every night.
- Integration with solar PV, allowing you to charge your car using free, renewable energy.
- Safety and compliance with Irish electrical standards and SEAI grant requirements.
- Smart scheduling to charge during off-peak electricity rates.
Portable chargers simply can’t match that level of performance or peace of mind.
So, Are Portable EV Chargers Worth It?
Only if you absolutely need a backup or travel frequently to locations without charging options.
For everyone else, a fixed, SEAI-approved home charger offers better value, efficiency, and safety. Especially when installed by professionals like WattCharger.
