does iPod touch include a charger in box? or is it an additional cost?

No, there is no charger. There is just a cable which can use to charge it from your computer. Actual chargers are available separately.

No it isn't - how can it be, it's just a cable. You plug it either into the computer's USB socket or a separately purchased charger (which has a USB socked). If you happened not to have a computer or a charger available the cable would do nothing,

But doesn't the cable charge the device once plug it in the computer? My cable does, that's why I'm technically calling it a charger. I'm guessing there's a different charger I'm not aware of.
It's just a cable, you are fooling yourself. When plugged into a computer, the computer is the charger.
Try plugging the cable only into the iPod, see how long that takes to charge.
Well thank you for an actual answer. Instead of someone saying "no it's not a charger", you actually explain because I'm new to this. Because what I was thinking was as long as the cable plugs into the computer and into an an iPod it's basically the "charger". Not one where you don't need any outlet or USB port. You learn something everyday though.
Everyone is a little confused... There is really no such thing as a "charger." The USB adapter (which I think is what is being referred to here) literally just lowers the voltage of the power outlet as it would be too high otherwise. If you plug it into the computer, there is no need for the adapter, as the power has already been lowered for the computer. You know how with the computer's power supply the cable plugs directly into the outlet? And how there is that little box about halfway down the cable? That little box is just another power adapter. The cable that comes with the iPod touch is the USB to Lightning adapter. It is just how the electricity travels from the adapter or computer into the device.

It does more than that. It converts AC to DC and if it's properly designed it assesses the battery condition and stops charging it when it's fully charged (or trickle charges it). The current available from the computer's USB socket is likely to be smaller so it takes longer to charge the device. The real point of the original question is that the box does not include a charger which would enable you to charge the device away from a computer, so it's important that prospective purchasers realise that they can only charge by using a computer.

Well, I thought converting AC to DC is a (perhaps desired) byproduct of the lowering of voltage. I'm no expert, so don't quote me. But I believe the way they lower the power (if I'm not mistaken) is by creating an electric charge with coiled wires. When the alternating current goes through the coiled wire, it creates an electric charge. Depending on how many coils there are in the wire, it can either lower, or increase the voltage (This is also how inductive charging works). I am not sure if it changes to DC through this process, or if that is done separately. Honestly, I didn't think it had to be changed đ BTW, can you site some sources? I am really into the whole electricity thing and could probably benefit from some of that stuff. đ
And I suppose you have a point there. It is true that the current model of iPod touch doesn't come with an adapter. So, it is also true that you can't charge where there is no USB. Sue međ But that doesn't necessarily mean you need a computer. Any adapter that lowers to the required power level (I don't know exactly what this is) should work. I often charge my fitbit with my iPod's wall adapter that I bought separately. Speaking of which, are you sure that the adapter assesses battery condition? I thought that was done by the device.
Today's power supply are switching powers supplies.

They do not use transformers/wire coiled around an iron core. he ones that use transformers are called linear power supplies.

Correct, you're no expert.
Changing voltage (either way) does not change from AC to DC or vice-versa.

Obviously, you did not read the comment I was responding to. And obviously you are not aware of the Laws and Guidelines of Human Logic and Sanity. In section A-113... I found three violations. I'm signing you up for the 10 Step Apple Support Community "Just Common Sense" Program. You can thank me later.
BTW, can you site some sources? I have a hard time believing you know your stuffđ
This is what you said that I comment on:

Because it is entirely incorrect and before anyone is tempted to believe you I corrected it.

The sort of old-fashioned power supply you are thinking of has a transformer with two coils, one supplied with mains electricity and the other outputting a different, usually lower, voltage by induction (this is not a 'charge' - a capacitor holds a charge which can be discharged when required - induction only produces an output when there is an input). This is still an alternating voltage so it has to be rectified, usually with a bridge rectifier, to produce a voltage which swings zero to the output peak, rather than going positive and negative. A capacitor is then used to smooth out the peaks and produce DC. This is very primitive - for one thing the output voltage almost doubles when under no load (because the internal resistance - losses in the transformer - is then insignificant compared with the route resistance so the entire voltage is applied to the output rather than its being divided between the route and the internal resistance), so it's normal to use a circuit to regulate it to a constant voltage over a reasonable range of loads.
These are bulky and heat-producing; pretty well all modern power supplies and chargers are switched mode - for a detailed explanation of that please see https://en.wikipedia.org/wiki/Switched-mode_power_supply as already suggested above.
You (I think it was you) made a reference to a 'block' fitted to the USB-to-lightning lead. Older iPod leads don't have this, and it's probably a simple ferrite core designed to reduce RF interference picked up by the cable - it has no effect on DC, just damps AC at higher frequencies. It's certainly not a charger.
When connected a computer the voltage from the USB socket charges the device quite slowly. A proper charger is faster and should have a built in facility to detect when charging is complete - probably switching off until the battery has discharged by a couple of percent then picking up again.
Ok, thanks. I learned something. But, wait. First of all, what generation of iPod was the original poster referring to? The little adapter I am referring to is about
1"" by 1/2"" by 1/2"", white, and comes with most iPhones. So, if I am getting you, I was right. There is no such thing as a "charger". The "charger" is the USB to lightning and a USB port being used jointly, what ever the USB is coming from. Right? Or am I completely missing the point?
What do you mean by charger? No wall charger is included
This is what comes in the box:
