I just want to use at a trade show-will they work without any amps, computers or other stuff-just plug in base and add batterys?

I'm pretty sure you have to plug these into some kind of system for them to work through your speakers.

Yes they can all be used to power devices without a computer but the amount of power each port has is very low compared to what a device would get from its own ac adapter.

These speakers are power hungry, I would not recommend running them without an amp, I fear you would be disappointed. The also sound a lot better in a sealed box. I had them mounted in my electra glide, and since the speakers are not air tight they did not sound nearly as impressive as in my boat in a sealed box.

You can run them without . That's what I'm doing now but it you what clearer and louder sound you'll need an amp

I cannot answer that question. mine are wired directly to a four channel amp. all I can say is without an amp they will not put out as much. they will probably sound like your stock setup. get a separate amp for them. mine has the boss audio 4-channel 400 watt amp. cost me $40

As long as you have them tightened down on the battery and the wires arent exposed touching any metal you will be fine. The amp has an on/off switch. As long as the power is off you wont be drawing any power from ur battery

If they didn't offer amps then they don't know themselves.Battery capacity and transformations with high voltage, I wouldthink similar but less than a spark plug jolt.

that is correct. if you connect them incorrectly nothing will happen. the voltage output will be one or two volts. if you connect them correctly you should get 18 volts. good luck.

No , you must hook them up to 110/220, they have battery back up for power outages only

They can operate without battery but you need batteries if you want to switch on the built in amplifier.

Nope it's 30-something ohm so any source can easily power them. I've plugged them into my android phone, my wife's iPad, and my work computer and all powered them easily. Volume levels were good and sound quality was great. I did get a budget dac amp for my work computer and I'd say there seemed to be the slightest performance increase, but it also could have been my ears getting used to the headphones. So no, an amp is not needed.

You will need some kind of power amp to drive these. Although small they are just a standard speaker as opposed to a powered speaker. Have a look at the Topping digital amps. I think they are great.

I just wired them straight into my deck and they work amazing, you DO NOT need an amp

They should be Ok for a cart. It would depend on the output from the radio itself. I have them on a pontoon without an amp and they are OK.

Yes, they work without batteries, you just won't have any noise cancelling.

batteries are not included. voltages specifications you need to turn one of these LED's are on these characteristics.

Yes, they come with a nice 120-230VAC to 12VDC Adapter. If you wanted to you could connect to any other source of 12VDC. It is a great product.
