If unit is powered by wall plug, does it depend on the internal battery at all or run independent or absent of battery?

If you read the TDK a34 Q & A section, it explains that the battery is charged not only when switch to "on", but when switched to off. The indicator light turns amber when fully charged if the switch is on, but when charge is complete and in the off position, the red charge light turns off (black). I confirmed this with my own A34, recently purchased.

When the battery is switched to "off" it will run through the power cord only and not use the battery but won't charge the battery either. The battery is only used or charged when switched to "on".

This unit MUST be plugged in to operate. Unfortunately it does NOT contain a standalone battery.

It must remain plugged in. There is no internal rechargeable battery or batter compartment.

The unit can be plugged directly into the wall and run without batteries. That was a BIG deal for me and I could not find the answer to that myself. So glad to tell you... YES! And I highly recommend this unit. Also, you can charge both batteries at the same time.

This item doesn't have an internal battery. It has to be plugged in during operation.

Jay P, I cannot really answer that question as we use it as a spare Fridge in our RV, so it is either plugged in and full or empty and shutdown. It is awesome and I am very glad that we bought it! Sorry, I could not be more helpful. Jeff

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.

Only one needs power, that would be the one that stays in the house. It needs (6) C cell batteries, I believe there is an external power supply for it, but I never used them. The batteries last quite a long time, depending on use of course. The wall unit outside needs no batteries. Hope this helps. I have in operation now many of these units, and they work just fine.

It can run while attached to a wall plug outlet. It can also run on battery until it runs down. It will alert you when it is getting low.

The unit will charge or discharge depending on what it is connected to. If it is connected to a device requiring power, then the batteries supply power to that device. If it is connected to a power source, it will draw power from the source to recharge the batteries (I'm assuming you are using rechargable batteries). For example, I have a portable MP3 player / remote speaker which has its own battery, but its battery lasts only an hour. Using the PortaPower, it will run all night. The MP3 player is not a power source itself despite having its own battery.

Absolutely not. Unit operates when plugged . Once you unplug ,if turned on ,starts operating using the batteries.

Battery is inside but we keep our unit plugged in to the wall. It holds a charge for a long time. We live it!

It does power unit but when plugged in Can not turn power off like the factory unit and actually have to unplug device or it remains on all the time. Kinda annoying but in reality not having unit on standby saves energy I suppose.

The battery charges anytime the unit is plugged into the wall. Should the power fail and the unit become discharged, it will recharge the battery when it receives power from the wall plug again.

When not in ise, the unit should be switched to the "off" position. It only needs to be plugged in for charging once the battery is dead--keeping it plugged in constantly will deplete the battery life (same as a cell phone).

Mine is a plug in device that hangs on the wall. It crapped out in about a year. So I can't help you with the battery problem.

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.
