Because it's portable what batteries does it require?

I believe you have to plug it in. I don't see any place where batteries can be put in. I always plug it in.

For me a power adapter takes the 'portable' out of portable. I have rechargeable batteries and don't worry about it. I take extra batteries when I travel, no big deal.

Mine used an adapter, not sure on batteries. It's has a required sleep mode, so I bet it also uses batteries if needed. We needed our baby sound machine on all night. Ours broke right away, but I remember thinking how nice it would be to take on trips because it was light and portable

It plugs in the wall. No battery. So not really portable but it is lightweight.

Not 100% sure, but I would guess - portable means it can be used with a Laptop, and not be stuck sitting at a Desktop only. It is USB powered, ...and that often refers to portability in many cases. One thing is for sure - it does not use batteries.

What electronic item in the world exists that doesn't need either a charge or batteries for power, but is portable? �

Batteries only, but that makes it portable, which is a plus, and they last a long time.

I think you mean battery or plugin and it is uses a single AA battery. There is also a rechargeable version of this unit which I didn't see the point of buying as I only use this when I travel and it is easier to carry an extra battery.

It is not a portable unit and does not use batteries. It must use the power chord to operate.

No batteries, first time you charge the portable charger for 8 hours, then it takes less time the next time you charge it. It provides approximately 3 hours of charge for your device.

It is portable because the unit can be carried on to different spots where the power 120V AC outlet is available like in the office, the house or car (with 120V AC output plug). You're right it needs a standard 120V AC (household outlet) to make it work. Unlike other portable stuffs like portable CD, DVD...they can use it's internal compartment with batteries (DC powered)

It does not come with a battery, and is pretty darn heavy (just got mine yesterday)--it's not meant to be portable at all.

No battery required. It uses power source and you need to have a long power cord of your own.

Batteries. I use rechargeable batteries but have to recharge them external from the camera.

It needs to be plugged in. The cord is about a foot long so really not portable.

It can use batteries or be plugged in, it comes with a power converter to plug it into a wall.
