shoes are max size 11.5/45

REEEEEEEEEEEEEEEEEEEEEEE

Chink siiizes.

Did you guys do the math on those giant lithium ion powerbanks and figure out why they're a bad idea

What's the maximum charge rate of the average USB port

I wonder

Is there chink camping tarps?

What's the optimal charge rate to ensure maximum 18650 cell lifetime

And other chink camping/survival stuff outside of the usual suspect

Hint: the math and data are against you

Which ones are you talking about bytemask

Are you an ultralightfag

Not really no.

Well considering that an average single 2400mAh cell should be charged at 0.5-1.0 c, the 500mA current on your average USB port isn't gonna do good for anything more than a single cell

Which makes a case for Qualcomm 2/3.0 style charge rates

@shadowedROM you should read the specsheet and find the charge cicle

But those aren't widespread

then use a microcontroler with a voltage comparator and a switching power supply

Well isn't everyone using a 2a charger anyway?

or you know, put like 4.2v continuously and pray

Also are they acctually damaged by charging at ~100mAh?

Other than it taking forever

The word is that low charge rates kill the anode and cathodes

no, only if you surpass the limit

Low and high are bad for different reasons

High is obvious

Low causes corrosion and decreased capacity

yeha, but getting more than 100 cycles from the cheap batteries is really hard

I just replace them...

Yup you're doing it right

Otoh

The guys buying 13000mAh banks don't know that stuff

I'm really fearful of housefires

I doubt they realize what they're signing up for

But this goes banks, not just chink and again why would you charge with a normal USB port and not your 2a charger?

you get 3000-3500mAh from a 18650

you're fooling yourself if you don't think the average person is using their computer to charge

Some guy is NZ is buying a big bank for $35

Scrolll up

usb 2.0 is like 100mAh

It's probably too late to tell him stahp
