Does it auto-power-off, or does it stay on all the time? Several have mentioned dead batteries.

Out of habit, I turn off the power. I have not tried to determine if it has an automatic time-out feature. I suspect that it doesn't.

Hi, I just checked it as because I never switched it off by hand until now. The gauge comes with auto-power-off after ~5min it switches off automatically.

It does auto Power off. I have used it to build a race car chassis and many other tasks around the shop. I have used it once a week for a year and have yet to replace the battery.

Mine does have an off switch but when it is on it automatically shuts off after 20 minutes. Did you try new batteries? that's pretty odd that it doesn't shut off in the off position. I would contact the seller. You may have a defected one! Sorry I couldn't be more helpful.

I have power ran from battery straight to cap... It does turn off after it is fully charged up! It's actually pretty cool.

It stays on all the time unless you specifically turn it off. We never do and it works fine.

After being unused for maybe a minute or so it will automatically shut off. So, if it says hold that is fine, it will turn off by it self and conserve your battery.

Harold, I've had mine a few months now and it turns off automatically. I haven't had to replace the batteries. Contact Amazon or the supplier about an exchange.

I can double check, but from memory, it is always on. The battery consumption is so minimal that it doesn't need to shut off.

It shuts off and doesn't drain the battery much. I'm not sure how long it stays on.

Yes, it will turn off by itself. It does stay on about a minute or so. I have never timed it. I would suggest using rechargeable batteries.

It stays on until someone answers it (turns it off). I don't know how long it will stay on because I've always shut it off.

HelloI believe you may unhook the batteries any time, as the same happens when the battery is full, it automatically shuts down,ThanksJohn

It doesn't have automatic shut off. Will stay on until you turn it off or runs out of battery life. If you use it for alarm purposes, yoy may need ro keep ir plugged in to power supply.

Yes, it turns off automatically. I have had this for almost a year and like it.

It doesn't have an automatic shut off so if you turn it on it'll just go and go until the battery goes dead. I'm not sure how many hours of battery time it's good for but I've left mine on all night long on several occasions and it's still going strong!

I've never left it on all night so I'm not sure, but I haven't noticed an automatic shutoff mechanism or anything. Remember that it takes batteries so leaving it on all night could eat through those pretty quickly.

I only turn it on with the battery is low. It automatically shuts off when the battery has fully recharged. The battery pack itself lasts a couple days before I need to recharge it.

Haven't used it yet, but it is advertised as a "stay on" unit, no auto-off. Hope this helps
