I plugged in my StopWatt a few weeks back near the breaker box. Green light is on steady but I can’t really tell if it’s doing anything. Anyone else notice any change or is it just a fancy nightlight?

Mine’s been plugged in for about a month and honestly, I don’t notice anything different either. The light is on, so I just assume it’s doing whatever it’s supposed to do.

I had the same thought when I first plugged mine in, but after a couple of months I did notice my power bill was a tiny bit lower. Could be coincidence, but I figure if the light is on and it’s not hurting anything, I’ll just leave it there.

Kinda in the same boat here. I figure if the light is on and my bill didn’t go up, maybe it’s doing something quietly in the background. I’d probably just leave it plugged in and forget about it for a few months before deciding.

Green light just means it’s plugged in and getting power. Hard to say if it’s actually doing anything without a meter or something to compare.

I’ve been thinking about picking one up, but it sounds like it’s hard to tell if it’s actually working. At least the light is pretty, I guess.

It’s probably fine. Green light just means it’s getting power, not that it’s magically saving you money. If your bill hasn’t changed, you’re not missing much.

Green light probably means it’s powered on, not that it’s actually fixing anything. If your bill looks the same after a few months, it’s likely doing nothing.

Green light just means it’s powered up, so that part’s fine. I’ve had mine for a couple months and my bill didn’t really change, but I didn’t expect much from a little plug-in thing anyway. Works as a nightlight if nothing else.

I’m not convinced these things do much beyond looking like a little gadget. The green light is just a power indicator, not a performance meter.

[Julia Writes]

I think people overthink the green light honestly. It’s just telling you it’s plugged in, not that your bill is dropping instantly.

[Maya Singh]

Honestly, I wouldn’t stress about it. I’ve had mine plugged in for a while and the light stays on, no drama. I figure if it’s not messing anything up and the bill isn’t going up, it’s fine.

[LauTop]

I just leave mine plugged in and don’t really think about it. The light stays on, no flickering or anything, so I guess it’s working as intended. Hard to say if it’s actually smoothing out anything, but I haven’t had any issues with my appliances acting up since I put it in. Could just be coincidence, but I’ll leave it there anyway.

[Rachel Mendez]

I agree with Mike in TX that the light is just a power indicator, not proof it's doing anything. But I'd push back a little on the idea that no bill change means the StopWatt is useless — its stated job is smoothing and filtering the current, so the fair test is whether things like flickering lights or appliances acting up settle down, not whether the bill drops. If your bill looks the same and nothing electrical has changed either, that's a reasonable sign it isn't doing much for you in your setup, and I wouldn't keep expecting a sudden difference.
