Crap face that is worthy!

Don't buy that battery! They're completely lying about the capacity. Buy your batteries off of batteryspace.com.
Remember that Lithium Ion/polymer battery packs are made of cells that output 3.7 volts. That means that a rechargable lithium battery pack's voltage is going to be a multiple of 3.7. The link you posted is a 12v lithium battery, which is impossible, and is a big hint that it's crap.

Nope. It just means that it has a step up regulator.

That is how ALL external phone chargers work, by boosting the voltage up to 5v. External laptop chargers boost to 12, 18, or 24v. It probably is a flaxty battery, but the voltage is no hint or surprise.

Oh really? Cool. Just out of curiosity, why is it necessary to boost the voltage up to charge things?

 

[PalmerTech]

Because most things that need charging expect a certain voltage, particularly devices that regulate the voltage back down into several other voltages for the internal components. In that case, you need to keep the voltage above the drop-out of the regulator.

This seems like it would be an interesting thing to take apart, maybe even portablize. Because you can never have too many systems in one portable haha.

*Edit* Also, this looks like quite a decent amp.

On a sidenote, why do these exist?

For E-Cigarettes?

What about a screen with built-in speaker?
Would it work fine?

They should, seem quite expensive though.

Wouldn't this fit on the Wii key? This is the cheapest CE ZIF plug/adapter I could find online

Your question about the adapter is not a simple yes or no...


If you plan to use that adapter make sure you pay attention to your pinout..
Those traces are all over the place...
If you are looking for the "cheapest" solution, this will work but pay attention to which wire connects to where..this board may be more complicated and confusing to use than a newhaven adapter for a few dollars more.
