Nitecore Intellicharger i2 - 18350?

Do these chargers auto detect all regular lithium ion rechargeables? It doesn’t list 18350 on the back of it, but I know it will work with RCR123 and it lists that. A friend is wondering if it’s alright to put an 18350 cell in it.

Tell your friend that it is perfectly alright to put a 18350 Li-ion cell into a Nitecore Intellicharger I2.
It is the opposite of “one size fits all” > if you can charge 1 size Li-ion in it you can charge all Li-ion cells in it.
With one possible exception: the cell is too short or too long to be “grasped” by/in the slot. So it is OK.

It is so. Just keep in mind the charging current. For cells 14500 and 10440, the charging current may be too high.

It does list 14500s on the bottom of it and he charges those in it.

Thanks for the quick answer. He got a new light. He might get bit by the flashlight bug
