Power Banks

Don't power banks start degrading horrible if not used correctly?
I never tinkered with them so what do I know.

Top of the line cells are 3200 or 3400mah, China cells are usually half that if that. They're usually paralleled then ran through a boost converter to 5v. You can eyeball how many cells would fit and do the math.

They're pretty hard to mess up when in a power bank. It's a easy life compared to being dead shorted to fill some kids lungs with burnt sugar. Just don't drain the pack till the protection kicks and not charge it for a year.

Why would you need one mega capacity power bank? If you need more capacity, just buy another power bank. You won't be saving a lot in terms of physical space because bigger power banks are just simply more batteries. I also find huge power banks not as convenient because if I don't need the capacity, I'm stuck with the one HUEG power bank. Sometimes, I just need a 4000mAh just in case.

>Well, why don't you just buy a smaller power bank for those occasions?

Exactly. Get multiple power banks. In addition, they'll charge faster than one mega power bank.

You mean a third?
You also mean used cells from 2009 that already have 300 cycles?
You also mean came from a failed pack where the one cell was discarded and the others are soon to follow?

What are some decent power bank brands? Is there even any reason to buy a quality power bank, or any cheap chink will do the trick?
