	The GEN1 chargers are considered to be more trouble-prone than the later units, and are not as popular for use in EV conversions or ground-up builds, partly because they do not support 3-phase AC input. However, they are used in many OEM installations that continue to need servicing. Examples of OEM installs include Telsa (all 2012-Sep2013 Model S), Toyota (all 2012-14 RAV4 EV<ref>https://en.wikipedia.org/wiki/Toyota_RAV4_EV#Second_generation_(2012)</ref>), and Mercedes-Benz (initially "Electric Drive", later "B250e"<ref>https://en.wikipedia.org/wiki/Mercedes-Benz_B-Class#B-Class_Electric_Drive</ref>, 2014-17). As far as is known, these are identical from a hardware perspective<ref>https://www.myrav4ev.com/forum/viewtopic.php?p=29981#p29981</ref>, but the firmware differs and is not interchangeable between installations.
