Sure, it can be left plugged in so long as you want, its always charged that way.

No, the instructions state charging it more than 8 hours can damage the taser and void the warranty. But once fully charged you could leave it on say your night stand untill needed.

Manufaf said this- IMPORTANT: Do not charge for more than 8 hours at a time. Overcharging can damage the unit andvoid the warranty. Under normal use the unit will need to be recharged for 8 hours every 60 days.

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 think they say not to use it plugged in, but the charging time is a short four hours and the charge lasts for many hours, so the power it uses without being plugged in is more than sufficient to tackle the job.

You can leave it plugged in if you wish. I usually unplug it after fully charged and let it sit. It keeps the charge for many weeks.

Ella, you can leave it plugged in in definitely. With that said, if your going out of town, or won't be using it for awhile, I would suggest unplugging it, just to be on the safe side. One more suggestion... I would use a surge protector at all times on any electrical devices such as this one. Please know, that I did not like mine and it did not work for my needs. I am still awaiting Amazon to pick it up and refund my account. That being said, if it works for you, and you like it, then by all means, keep it and use it. I hope this information helped helped you out? If I can be of further help, feel free to ask any questions. I'll help if I can. Thank you, $BILL Ella, you can leave it plugged in in definitely.

The person I purchased this unit for, leaves it plugs in at all time. She unplug unit for several day while on vacation, and the battery died. So I suggest you leave unit plug in at all time to preserve the battery life.

you can leave it plugged in as long as you like. the light changes color when it is finished charging. will need new usb cord though. it may also break if you are trying to recharge a high amp device. my GF uses it every other day, it gets pretty hot when charging her phone.

According to my wife the answer is no, it must be plugged in. She loves it though.

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.

No. You can leave it plugged in as I do. I do press the off button when I'm leaving the car, however.

I have left mine connected without being plugged in for a few hours without a problem. But I don't know about permanently I have never done that.

A regular will do. Since it is heavy duty and does not unplug easily, I usually leave it plugged.

When it is connected to your plug yes but it is best to have it connected to a battery

No, not at all. The best way to do it is to fill it up, let it sit for a few minutes, then fill it a little more. Then you can unplug it, and it will be fine for the rest of the night.

This unit has to be wired in and charges until needed should the power go out.
