Can I charge 18650 cell W/ an internal charger using an external charger

Might be a stupid question but I am not sure….
I have a 18650 cell with an internal USB charger.
Can I also charge it using my Opus charger or only by using the USB socket?

Either are fine. You have more control with the Opus if you like. USB does what it does.

You know with these proprietary frigging batteries today, who knows.

@zoulas could be right, but I don’t think so.
Does your’s have a cap that comes off with a ‘regular’ external USB plug-in, or a micro-USB slot?
Not that I think it actually matters.
Here’s a slot version being tested: Test/review of Lumintop 18650 3400mAh usb (White) LM34C
He charges it either way.

Thanks, Will try it :slight_smile:
