Both these products are now retired. JuicePoint’s recommended alternative is the JuiceBox 40 T1 or JuiceBox 40 T2 for most customers charging at home. The JuiceBox 32 is recommend if 3 phase power is available.
Why is a JuiceBox Better than a Plug in Charger?
- Plug in chargers were only recommended for occasional charging.
- They are referred to as “trickle chargers” – which is fine for a Nissan Leaf with a 24kW battery, but it quickly becomes impractical with newer EVs with larger batteries, for example a Tesla with 100kW battery will take over 2 days to fully charge! See our how fast to charge article.
- Degradation of batteries (especially Leaf batteries) is related to time on charge – so a faster charge is better for the battery lifetime.
- Plug in chargers are limited to 8A by WorkSafe, Wall Boxes can charge at up to 32A.
- WorkSafe requires a dedicated circuit for the charger. Upcoming wiring regulations will make the installation cost comparable to a Wall Box anyway.
- WorkSafe is guidelines strongly discourage allowing a staff
member with an employer owned vehicle to charge the
vehicle at home using Mode 2 charging with an in-cable
control and protection device (IC-CPD). This is because
it relies on the safety and integrity of the home’s wiring,
something that the employer has little control over.
- Be very cautious buying a plug in charger that they meet WorkSafe requirements and applicable standards for New Zealand. Refer here for more information.
