Most “charger choice” debates are really about how you want charging to behave and how the installation will be managed safely.
Tethered vs untethered (the real trade-offs)
Tethered (fixed cable)
Pros:
- Cable is always there — convenient day to day
- Less chance of arriving home and realising the cable is missing
Cons:
- Cable management is visible; can be awkward in tight spaces
- If the cable is damaged, replacement may be more involved than swapping a portable lead
Untethered (socketed unit)
Pros:
- Cleaner wall unit; you choose when the cable is out
- If you need different cable lengths, you can swap leads
Cons:
- You must bring/use the cable consistently
- More “parts” to manage (especially for multi-vehicle households)
Smart features: what matters, what’s just “nice”
Useful features often include:
- Scheduling (align with night rates or household routines)
- Load management (avoid overload by adapting charging to other household demand)
- Usage reporting (helps with cost tracking and debugging)
Features to think carefully about:
- Cloud/app dependency: what still works if the internet is down?
- Vendor lock-in: are you tying control to one ecosystem?

Safety and compliance questions (high-level)
You don’t need to specify protective devices yourself, but you should ask:
- Will the installation comply with applicable standards and manufacturer requirements?
- What testing/certification will be provided at handover?
- How is isolation handled, and what is the safe shutdown procedure?
If the answers are vague, prioritise a better installer over a “better” charger.
Solar-linked charging: set expectations
Some chargers offer “solar modes”, but the practical result depends on:
- How variable your PV generation is (clouds cause rapid changes)
- Whether your car and charger can pause/resume cleanly
- Whether you have a battery that can smooth fluctuations

Common questions
Should I buy the charger before I pick an installer?
It’s often better to align with an installer first, because cable routes, supply constraints, and mounting location can influence the best choice.
Do I need a “smart” charger?
Not always. If you’ll rely on scheduling, load management, or solar-linked behaviour, smart features become more relevant.
Is one brand “the best”?
It depends on your constraints and what you value (offline behaviour, app reliability, integrations). Prefer clear documentation and a credible installer over hype.
