PPDRAW Automotive Battery Voltage and Parasitic Draw Monitor with OBDII Connection

Works really good in the aspect of the tool itself, but does not link up to the app consistently. It's kind of all over the place

This tool is awesome! I use it two different ways. It is largely used as a memory maintainer while replacing a battery which keeps me from having to reinitialize anything after the repair. I have also used it during diagnosis for parasitic draw and I have compared it to the reading on my meter. It's accurate. And it is SO much easier to use than the old conventional methods. It seems to be solidly built so I would definitely recommend for anyone involved in electrical diagnosis.

Great Diagnostic tool! So easy and powerful., Cant diag with out this one now Its a must have for anyone serious about electrical diag.

Great tool if you know how to use it properly.

I bought this for my husband for Christmas. He has used it now and is happy with it. Said it worked very well and glad I got it for him.

Good quality, basically a metered battery for finding out parasitic draws on vehicles.

Easy-to-use, worth the price. Money maker on the first diagnosis pay by self.

It took over a year and a half of chasing ghosts trying to find my parisitic draw, and not to mention it caused two batteries to die. After getting th pp draw it took me 2 days to discover a relay tucked way under my dash from an aftermarket remote start that was bad. The beautiful part was being able to physically watch the mili amps change when I disconnected the bad relay.
