Both these products are now retired. JuicePoint’s recommended alternative is currently the JuiceBox 32.

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 members 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.
