12v obd Car memory cable ?

[GophersGarage]

I am currently looking for options to purchase a
obd cable to keep power to car during battery change .

But got me thinking that I now have to lug around and have a spare battery to connect to .

Instead how about a smaller battery booster pack that I can just connect that to cigarette lighter port .

I do own the noco gb150

But I bet the basic gb20/40 would do the trick and super compact

Your thoughts ?

A booster pack works fine as a 12v supply for memory savers. We have a couple different ones at work and use this (link) memory saver with them all the time. https://www.amazon.com/Schumacher-OBD-L-OBDII-Memory-Detector/dp/B00CH59OAS/ref=asc_df_B00CH59OAS/?tag=bingshoppinga-20&linkCode=df0&hvadid=&hvpos=&hvnetw=o&hvrand=&hvpone=&hvptwo=&hvqmt=e&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=&hvtargid=pla-4584070138114675&psc=1

Make sure the outlet you plug it in to is hot all the time and not only when the key is on.

Yep, 12v plug in the booster for power, DLC plug then supplies it to the ECU. It will indicate if the unit is working or not with some lights on it. Pretty slick actually.

I have a 12 cable that I plug into the DLC and cigarette lighter outlet on my JNC660 or JNC750 jump pack.
