I have no interest in using the internal batteries. I am wondering if these devices can stay powered on constantly if plugged in via USB. Anyone try?

If the internal battery is drained then unit will not work correctly until the internal battery has some charge. I have tried to plug the unit in to the usb charger after the battery drained but then had to wait some time for the battery to charge before it would work right. I suppose as long as you keep it plugged in to a usb charger all the time then the battery will stay charged and so should work.

We usually don't use ours for more than 90 minutes of continuous use. They could probably hit 2 1/2 hours with a decent battery, but it might be a stretch. I don't know if you need them to run continuously for the whole time, but we try to conserve power by turning them off when not actively in use. We're running them on Energizer rechargables.

Did everyone try charging the unit while it is powered off?It seems to make a different to me. I bought three(3) and so far all battery seemed to be decently averaged out around 2.5 hours or so (mainly net surfing and video conferencing) after few months of usage. Power on while charging seems like charges don't hold too well even it shows 100% charged.Try it out...it may make some different.

For me, this thing is unusable. The headset battery is about worthless as it discharges on its own in less than 12 hours. You could keep it plugged in to the USB all the time, then that would not be a problem.

I keep mine on a Schumacher Smart Charger 24/7 and its been sitting for over a year on that charger. Used it as a battery backup system in a simulated "black out" scenario last weekend. Ran 5 light bulbs, a HAM radio, and charged electronic devices off of it. Pulled very little voltage and after running it for hours the monitor I use still showed an full charge. All that to say, the battery seems to be holding at peak efficiency.

It always need to be plugged! the device does not have an internal battery, but it works great!

I have tried it both ways, but it always seemed that when I left it unplugged and needed it, there was no power. Now I leave it plugged in all the time. However, probably like other devices of this nature, it might be a good idea to let it run out occasionally and recharge.

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

I never thought about this. I keep my batteries charging all the time. I haven't noticed a problem. Yet, that is. Christine S may have a good suggestion.

Yes, a device like this would cause a powered external drive to stay on as long as the USB hub is powered.

I've got them all over the house and I haven't found a USB device they won't charge yet. I can tell you they successfully charge various smartphones, wireless speakers as well as the larger iPad that requires 2 amp power bricks. On a side note, we had an electrician over for something unrelated and he loved them. He said it's the best USB wall plug he's used yet.

Hi Eric. Never tried it. I thought the USB was for wired page turning. Fresh spare batteries a must at every gig.

Experimentation tells me that the answer is NO. My experience with bus powered USB hubs has been problematic. Commonly you get a "power fault" on one or more of the devices involved and restoration is very difficult without rebooting (ugh).

The one I purchased could only be plugged into a USB port for power. As to leaving it all all day, I would say that I've only had mine on for a few hours a night because even though the lightning bolts can be seen during the day they are more dramatic in a darkened room. It is well made, so I see no reason it couldn't be left on all day. Hope this answers your question.

You can leave it plugged in using a usb cable with a plug in adapter at the wall, similar to a lot of devices now that charge via usb cable. Just leave it plugged in and it will operate off electricity and keep the battery charged. Be aware that on mine the water in one speaker quit "dancing". Not sure what this was related to but probably not a power issue but defective.

You must use good batteries. I've been using Energizer. Also, it may not give you a fuller battery if the batteries are not new, but you should be able to use your device while it's plugged into the backup.
