The JuiceBox Pro 40 EVSE now has UL listing
A little over two years ago I posted a review of the JuiceBox Pro 40 EVSE from eMotorWerks here on InsideEVs. At the time eMotorWerks was a small company based in California, just beginning to become known in the EVSE industry.
I was impressed with the features the JuiceBox offered, particularly the Wi-Fi connectivity and the JuiceNet app. The app allowed users to view their charging activity in real time, adjust the amount of energy their car was getting, access records of past charging sessions and set up notifications. At the time, it was the only residential EVSE that allowed this kind of connectivity and access to energy use, and it was also one of the few EVSEs that was also available in a plug-in variety.
However there was one drawback about the EVSE that detractors frequently brought up. The unit wasn’t Underwriters Laboratory (UL) approved. Despite quality and safety assurances from eMotorWerks personnel, the fact that the unit didn’t have UL certification caused a lot of potential buyers to pass on purchasing one.
The UL certification can be an expensive and time-consuming process, and small companies just starting out sometimes pass on it until they have the working capitol to apply. Also, if they make any changes to the unit they then need to get it re-certified, so often a small company may wait a while before applying for certification because if they plan on refining the unit a couple times in it’s early stages of availability.
I personally used a JuiceBox Pro 40 for two years to charge my EVs and never had a problem. However, now the concern of a possible lack of safety can be laid to rest as eMotorWerks has recently announced that the JuiceBox Pro 40 EVSE passed Underwriters Laboratory testing and is now UL listed.
This is newsworthy because the JuiceBox has become a very popular EVSE, and the fact that it wasn’t UL listed has been a hotly debated topic here and on many online EV forums.
In addition to the recently-updated JuiceNet app, eMotorWerks continues to innovate. They recently partnered with Share&Charge for the first peer to peer network, allowing JuiceBox owners to rent out their charging station and get paid to do so.
