What is the standby current draw when no devices are plugged in? I note it has an LED which would always draw power, etc.

The package lists 15mA but measured only 11mA of parasitic draw. The draw is because of the led, and is pretty good, but I added a switch to turn it off. My camper has about 100mA parasitic draw which is high when compared to a typical car of maybe 30mA.

Very little. 15ma maybe? I usually only drive my van every other week or so and there is no noticeable draw

I installed a switch between my power source and the socket to eliminate any current draw........ no problem !

As it uses an external power supply (not just power from the USB port), the power would remain on. I plug mine into a multiple power outlet device which I turn off after shutting down the computer and so the power will not be on all the time.

YES. It draws no power unless a device is attached. Cables only attached drew no power. I used a Kill A Watt to confirm. Hope this helps.

No, there is no standby power; no battery. When it's off, it's off. I'm very happy with my Tivoli.

If it is turned on (lite on) its drawing power ...minimum but drawing power...plug it in a power outlet (lighter) that cuts off when key is off

The standby current draw is slight, so leaving the inverter on when it is not supplying power won't significantly drain the source battery over a period of a few minutes.

Can anyone confirm that this device has built-in battery? Mine would stop working when unplugged from 110v outlet.

You don't have to unplug it. I keep mine plugged in with no problems. Nothing remains running. I'm not even sure why it says that.

Not sure of the "current draw" but it must plug into a 110V outlet. Probably not much draw as it only works a circuit board and small fan.

It must be plugged in. It doesn't have a battery because it uses too much power for a battery.

Hi John, I am not absolutely positive (had to return the laptop and, therefore, cannot check right now ), but if I remember correctly it's the indicator light for the power. When the battery is low, this light turns red.The little light to the left of it indicates if the laptop is on, and it blinks when in standby.

This is just a guess, but LED light technology is such that the light will still work even if there is just a little power remaining. There just might not be enough power left to charge your device. It's possible that you just have to re-charge your battery by plugging the micro-USB cable into the battery and connect the other end to a power source. If that doesn't work, contact the manufacturer.

We leave plugged in most of the time but it holds a charge indefinetly unplugged. I hope it helps.

Its a portable power source...you keep it plugged in at all times.In the event you need it,whatever is plugged into it,will receive power fro this unit,ntil it runs out of power or power it is plugged int,is restored. It would probably run a small fridge,depending on its wattage,also several small light fixtures,again depending on there power consumption.In a power outage,providing it is plugged in,it will automatically come on ,if needed.One of its best features.

Mine doesn't. It still provides power until the device stops requesting it. It would waste power. If you want to see the status, just click the button again.

The light is supposed to turn off when the battery is charged. If it only works when plugged in, that defeats the purpose. I'd contact the maker. Sounds like yours is defective. BTW, did some long workshops this summer. did recharge during the lunch breaks. The battery seems to last about 7.5 hours.

Yes, the USB charging circuit in this outlet does use power even when nothing is plugged in. I tested by wiring a Mastech MS8264 digital multimeter in series with the hot lead that powers the outlet. With nothing plugged into the outlet, the multimeter read 0.42-0.44 milliamps at 120VAC. Note that this is not a true-RMS multimeter; the actual power draw was probably more like 0.66 milliamps. That's less than 1/10th of a watt, which might be so little that it doesn't matter to you, but it is definitely nonzero and does add up over time. My review contains some more details about power draw:
