Lightest 18650 charger with 2A or higher charge current.

I attached a pair of leads to this

And use it as a tiny charger for trips. But it takes forever when charging a pair of 3400 18650s @ 1A. Does anyone know of a super light and tiny charger that can charge at a higher rate?

thanks, but I’m looking for something much smaller.

Two of thees in parallel :wink:

I didn’t think you could connect chargers in parallel.

How long does it take? How long is too long?

I usually put in on before bed and its still going in the morning. So over 8 hours for 2 3400s.

Is it safe to connect 2 chargers in parallel to one battery?

i don’t know if it is but it adds another failure point so i wouldn’t do it, just buy a 1A charger, it should charge a 3400 in under 4 hours

One easy change is to Charge only one cell with one module, that should shorten the charging time by half without worrying about something.

I have read here somewhere that these chips can be paralleled(or that some chargers do this), but I am not sure if this is true I doubt it.
I have glued a small heatsink on one of my 1A modules, as I don’t want it to decrease current because of over temperature.
