Can it be used while traveling on a bus that does not have an external outlet. It says it was portable.

Yes charge it full before you head out, and you'll be able to run off of the battery until you reach your next powered destination.

Yes, you can use it, but regarge it before taking to outside. Unfortunately, it does not keep long power supply as characterized by producent.

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

I use mine plugged into an electrical outlet, but it comes with a AA battery in the transmitter that can be used for portable use. I cannot verify how well it works, but the battery in the headphones and transmitter should be fully charged for best results.

No, it is powered by plugging into an electric outlet. The USB provides a connection into your computer. This not a bus powered drive, neither it is portable.

Yes you can. It is stable enough to sit atop of both legs when seated. Like any device though, enough motion will cause it to slip off of your legs like a laptop would. The light weight of the device may make it easier to bump around but I personal have no issues on the bus using it on my lap.

Portable does not mean battery-powered. It means it is light and small enough for you to bring it in and plug it anywhere.

Yes, it must be plugged in to be used. The good thing is, it won't run out of charge during use.

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.

It doesn't have a batter, and it's not designed to be portable. It's relatively heavy for it's size and it's awkward to carry. You could certainly bring it somewhere in a pinch, but it will still need to be plugged in.

It is portable meaning you can take it anywhere and it will fill a yard with music at an outside party but it does need to be plugged into an 110v outlet or generator to work. There is no battery. I love how powerful and rich sounding it is tho. When outside I just run an extension cord into the hone.

Bus-powered. I tried charging my phone without the cable plugged in and nothing happened.

It is portable. The power cord from the Nuvi when used still attaches in the back of the Nuvi and is three feet long plugging into 12V receptical. That means you can put the whole unit out of sight when not I use.

I wouldn't necessarily call it portable -- it doesn't have handles to carry it and it isn't compact. But it is self-contained with speakers and can be moved without disconnecting components.

yes you can but why would you want to plug it into the wall if its portable

It can be plugged in at home to recharge or in most all electrical outlets anywhere. It really comes in handy when a jump is needed. Have used ours several times, when wiring in my car kept pulling the batteries power down and killing it! finally is fixed, but still keep it charged and in car when traveling because you just never know! Hopefully this answers your question. JWA
