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 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
if you speak the protocol you can get 500mAh maximum
per specs
but needs negotiation
Yeap. For single cell 18650 its fine, as would a Lopo at around even 3000mAh
But charging a 10Ah battery on 500mA is silly
Lipo*
Or even 2A
you can use those cheap RC battery charger for planes and shit
they have everything
Yeah I think you're preaching to the choir
Like I said
I don't think normies and other /csg/'ers know what they're going in for
