Will I waste money and power if I kept this plugged in every day, even without batteries in them?

I leave mine plugged in without batteries with no ill effects so far. But am concerned about power surgesrecently. They have reset my computer even with line conditioning and battery backup. Prob. from on/off/on cycle.

The Sony BCG34HLD consumes less than 0.5W of power in standby mode (plugged in but not charging). Even if you leave it in for a year, the energy wasted is just around 4KWh. That comes to about $0.60, assuming $0.15 per KWh.

I just leave the pad plugged in all the time. I don't think it consumes much power.

Yes, but I use the battery alone without the plug in power. My shop is off grid so it is nice that I don't need to plug it in.

I do not know the answer to this as I always use mine plugged into electricity.

No. A battery backup is less necessary than most people think and unless you live in an area with frequent/rolling blackouts I'd just get one of these and spare your wallet.

I never run it with the battery. It stays plugged into the wall the whole time.

Not necessary. It has an "Auto-off" feature, so you can leave it plugged in.

Yes. I leave it plugged in since I use it at home. If the battery runs out, it will take some time before it charges enough to use again. I expected it to work as soon as I plugged it in but it didn't.

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.

Yes, you can keep connected and keep the battery charged as long as the solar panel is also installed, I use it daily to keep my batteries charged and mew so far has given excellent results

Yes. I keep mine plugged into their wall at all times. But they do have battery back up. The electricity went out once and the monitor worked fine.

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.

No. After use I unplug from electricity. I use this only once a moth to backup my computers.

I would have it plugged into my truck 12v outlet all day while driving, but I would unplug it in the evening and let it maintain whatever coolness it had. However, I didn't want to run down my truck battery, so I never attempted to leave it plugged in for too long without the truck running. Sorry I can't answer your question.

Yes, I leave mine plugged in all the time. It stays quite cool when not use.

Yes, just be sure to buy an AC to DC power adapter. I've had mine plugged in for over a week at times.

No. The unit is powered from a permanently sealed battery with 10 year life and cannot use external power, so there would be no point in doing so.
