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

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
