Can you plug something like a tv into this unit, (use the battery power) while the unit is charging simultaneously?

Hi James, Thank you for you inquiry! Yes, you can both draw power and recharge the unit at the same time. Please let us know if you have any additional questions. Best regards, Earthtech Products

Yes, the unit can be plugged in while charging an iPhone (i.e., it works); however it's technically better for the charger to do one, or the other, at one time.

I have it plugged into a USB port on my TV, but you can also plug it into a power outlet if you have a USB-wall outlet charger (like one used for a cell phone).

Yes. I use a charger that works via AC inlet, and I can use it at the same time. Never charged my unit via usb into computer though and tried to use it at the same time.

Didn't try that myself, but it worked when I plugged it in. Use it while it charges...

I Suspect this little unit will not put out enough power to run a TV or stereo. We use it to simply maintain a car battery, like a trickle charge and it does help with that pretty good.

Yes, but you need to buy batteries for the unit. It does come with a power supply that will charge the batteries. You can also run these off the AC power supply while the batteries are charging.

yes you can . but theres a power button next to each one . and you have to make sure you hit it and its going to show a blue light . even while its charging theres a blue light . but the end of the usb part has to be plugged into something so your several devices may all work at the same time .

Yes. That's what I do. My aux input is next to my USB so I plug the jack and charge at the same time.

Yes you can. That is how I usually watch. It takes longer to charge, but you can.

Yes, you can charge the 12 volt battery while the inverter is powering your appliances and electronic devices.

I did try doing just what you described because that sounded like a really nice feature if it would work. UNfortunately, no you cannot use a charged battery in the charger to power another device.

yes, you can......however I notice a buzzing sound when its plugged in. charging is so quick that keeping plugged in is unnecessary

Yep. And it also chargers 2 batteries at the same time if you want to. Hope this helps. Bye

No, you cannot plug this unit into the accessory plug and use it as a monitor for your battery.

Yes, you can! You will need to plug the USB port into something that can give the USB port power. If it's at your tv and you have a cable box, they usually have a USB port you can use for power. If not, find a USB charger for a mobile phone like an iPhone.

I can't answer if it's recommended or not but yes you can use while it is plugged in.
