SOLAR ESA30 OBD II Memory Saver Connector

Not sure if it was on this unit, or on the 2A power supply I used, but when changing battery, it aqppeared that a current limit was occurring, and I heard a funny relay click from under the dash from something that was supposed to actuate but couldnt. Was fine after the battery was back. But beware, this may limit current, and even if this can handle it, Im not sure how much current one should backfeed through the OBD port. Thats not a dig on this product, which is quality and gets five stars, but just be careful with your car!

This plugs into a 12v battery pack and feeds the OBD II circuit in my car, which is a 7.5v circuit. The fuse blows and memory is lost. Not exactly what I wanted....

Not really sure if this connector works when plugged in to external power/another car or battery. I tried this on my Nissan Altima and blew the OBD2 fuse right after I supplied power from another car. This might work with some other make or model car but have not tried it after that incident.
