Do I need to charge or need battery?

It comes with 4 AAA batteries that are not rechargeable. If you want rechargeable batteries I do not see why they would not work. My batteries are almost 2 years old, so battery life is not a problem.

I was unable to use the pump on my blood pressure tester. I tried to return it, but was told since it was not defective...just me unable to use it, the shipping charges on the return wouldn't pay for me to send it. A couple of weeks later I took it to my doctor...she was unable to inflate it either. Not defective? Only useless!

I don't think batteries were included with mine, but it uses very little power. I agree with previous post, a set of batteries will last you a long time.

No, you will have to take the battery out and charge it. Otherwise, you will have to buy two batteries... I hope it helps.

I charge it via my computer or eletricity. I do not know about battery, I think there is no battery attached to it. You are supposed to charge using your computer (USB port) or plugging in the eletrical socket.

You can charge it by plugging it into your pc, but I like to have that in case I am away from my pc. So I did need it.

None. As with any battery you want to keep it charged and not deplete it under 10%

The camera comes with a charger that plugs directly into the camera so there is no need to remove the battery to charge it. The camera can also be charged by plugging it into a USB port on your computer. I also baught a extra battery for when I was traveling just in case.

There is no battery needed. Alternatively, if you wanted to use a battery pack you probably can, but again, not needed. It comes with a Mini USB Male to Common (A-Type) USB Male Cable. Ive powered this from a laptop and had no issues. I also plugged it into an extra USB Adapter from an old phone and worked great.

Just plug it in and its ready to go. It may need charged but mine didn't. Mine is a trickle charger very low amps. Good luck

No battery required, just plug in. I returned mine, thin stream of air and not very powerful.

You have to replace the battery you want to charge it. And also you need to use the battery charger. I bought ot separately

I go ahead and charge it. I think you have to charge it now and then even if you don't use it.

No. You only need to charge when needed. I have only charged mine once in two years. And yes, I use it often.

I believe either is OK. I usually leave it plugged in during frequent use. For storage, I unplug then charge prior to use.

Yes, charge it before using it for the first time. Yes, charging it overnight should be enough.

Battery came partially charged.... you should probably charge it completely before using it....

I can charge it on the computer or I can take out the battery and charge it in the battery charger plugged into the wall socket. If you get an extra battery you can have a spare ready to go if you need it.
