Is this something you leave plugged into your car all the time or only when you need to read a code?

You only need to plug it in when you read codes,unless you want real time analysis.

You can do either. I only plug it in to read codes although I do leave it plugged in during vacation trips. It depends on how often you plan to read the info on the app.

You can leave it plugged in but be aware that due to the budget construction it has minimal protective circuitry and could have a short lifespan running constantly, and that many vehicles have powered OBD ports when not running so it will gradually drain your battery. Estimates for current vary but are generally between 50mA and 100mA which isn't a lot but is enough I wouldn't leave it plugged in for more than a few days without running the vehicle to keep the battery charge level acceptable.

I plug it in to read codes. I guess it could be left plugged in but I'm not sure.

That is entirely up to you. I leave it plugged in on long trips to monitor performance, bit take it out when we get home. It is used mostly as a code reader for my son's truck.

I've never had a problem with mine. I just leave it plugged in all the time why my car sits. For a few days to a week in the Northeast climate. I unplug it before I start my car. WFP

Its your choice, either to leave the plug in or out. I always unplug mine when I turn off the car. The sensors are durable. And you cannot change the batteries. You have the change the whole sensor.

This programmer doesn't stay hooked up to the vehicle. You plug it in and follow the instructions on the screen, then unplug it and store it in a safe place.

It is perfect for the occasional use vehicles, the charger can be left in maintenance mode (which it enters after detecting battery is full), to keep the battery in optimal condition so it's ready when you are. I have it plugged it to my 1972 Riviera which is used infrequently (especially not during winter months up here). I even modified one of the harnesses it comes with (the eyelet one), and it is now permanently connected to the battery and runs into the cabin under the passenger dash, and therefore I don't need to open the hood to connect the unit :)

yes, that is one of its modes, it also produces a report of trouble codes and sensor status when the engine is not running but the ignition key is in the on position. There is a little bit of a time delay between the instruments like rpm on your dashboard and the same display on whatever you have the sx plugged into, at least there is on the old laptop I use to read my codes, admittedly a living fossil.

I don't connect it to constant because it could drain your battery. I rely on the back up battery when the car is off.

Not sure understand question but there is a circuits breaker. Like an outlet should be on all the time. Not using power unless plugged into your car. Hope helps.

No, I think you have to keep it plugged in. I always unplug it when I leave the car. Kind of annoying

Think instructions say leave plunged in whenever car not in use. Left mine plugged in during winter.

Yes, if it's plugged into a continuous power port and you leave it on. One way I can tell if it stayed on is when I try to unlock the car with my remote. You have to be right next to the car to unlock it. I would steal it if I broke into your car. So I don't know if keeping it on would do you any good. It's a good monitor of what goes on around your car.

No need to leave it plugged in !Just like any electronic device only plugged it when the charge is low "I jumped 4 cars on one charge and it can do more!!"No sure about the float mode sorry !

As long as it plugs in.And it should it will tell you the code and reset it

If you hook this up, with a device connected to it all the time, yes as long as there is power to it all the time, it will drain the battery. The drop in voltage would depend upon what is connected to it and what the draw rate of that item is. When you hook this up to the fuse panel you will need to be on a circuit with a minimum of a 10amp fuse. You will also need to find a circuit that turns off by the ignition switch when the key is removed, or you will need to unplug your device to eliminate the draw of voltage by the device plugged in to this cord.

Yes, but you still have to unplug it when you start your car. Also if its anything like the one of got it wont last more than a few hours anyway.

I don't know. It was just an option on amazon. I leave mine plugged in the car overnight when it gives the one hour left message and have had no issues.

I leave mine plugged in all the time because I only drive short distances( less than 3 miles) which does not keep the battery charged as when you drive longer highway distances.
