Hi,

I was wondering about LiPo battery chargers.  They are described as making your projects mobile but here is my thinking:

1.  These modules require a power source from a wall charger with a barrel jack.

2.  Or they require a power source from a mini-usb jack from a computer (usually).

So yes, these modules can charge a rechargeable battery pack, but they require a power source which is either tied to a wall charger or a computer.  So it doesnt really make them mobile unless you can hook them up to a solar panel right?

Otherwise where is the true mobility of such a project.

Once you charge the battery you can disconnect the charger and carry your project around until you use up the battery charge.  It's just like a mobile phone.  If you want your project to last longer between charges there are ways to reduce power usage and you can use a battery with more capacity.

Ok so the advantage over replacing alkaline batteries would be the cost of those batteries.  But otherwise you still have to go doSomething() like replace the batteries or plug the rechargeable battery pack.

Another advantage of LiPo over Alkaline is that they hold more power for the same size and weight (or have less size and weight for the same power).  See: https://www.youtube.com/watch?v=52UQBID1Jbg
