The Mitsubishi Yazaki EV Charger case is quite difficult open. In addition to the screws the cover is glued on with silicon adhesive. We opened this case by cutting off on edge and prying open the case. We found water corrosion on the PCB and were not able to repair this charger. We did learn that this charger, Model 9482A347, is 240V compatible and can charge in 1/2 the time.
Many Blink WE-30 chargers are set to 24A but that can be easily upgraded to 30A to give your charger a 25% speed boost. Go to the Settings screen, press and hold Device Info for 15sec. Then you will be asked for the "Blink Maintenance Pin", Enter 906598 and you will get access to the Maintenance screen, Enter Max Current Setting - 30, and press done. There are other default settings on the Maintenance screen.
