Cheap & Big

Picked this up to charge 18650s and it does the job. Nice little display to show where they're at, holds a bunch of them and no problems so far.

Lots of cells
November 18, 2020
I chose this over a different 4 bay because I wanted the 8 bays to charge 18650 and 16340 batteries for all my flashlights at the same time. Not sure what to say, it has recharged them many times now without any issues. Works as I'd expect and I never have to think about swapping cells in and out to get them all juiced up.

Batteries need adjustment to charge
July 31, 2019
This product is just ok. You have to adjust the C size batteries in the slot otherwise it don't work. I have not tried other size batteries yet because I have other chargers for AA and AAA batteries. I love the 8 slots for charging C Size but I don't know yet if adjusting the batteries is worth the trouble. The Plus terminal doesn't seem to be long enough (Not Likely) or the plastics get in the way (Probably). I do not intend to send it back but some modification may be necessary. I gave it 2 stars because I really bought it for C size only.

over heats batteries
July 11, 2019
Upon receiving this device, I placed in AAA batteries to charge. They rolled or did not fit securely in the slots/spring loaded areas very well. The lights are only red, start out in the 1 blinking position and move up until all are solid. Once this occurred on a battery, I reached to take it off. It was burning hot. It took about 3-4 hours to charge, and I kept a constant eye on them. I would not feel comfortable leaving this to charge unattended like I do my 8 slot Tenergy TN145 AA/AAA charger.
This charger may do larger batteries, but the smaller ones don't fit securely & batteries are extremely hot.

Will this charger work for this type of battery that is unprotected and will stop the charging when battery is full. Efest IMR 14500 700mAh 3.7V Unprotected Lithium Ion (Li-ion) Button Top Battery
1 Answer
Thank you for your inquiry. The Klarus C8 is a smart charger, so it is a great choice to use with the IMR cells. The C8 has a trickle charge mode to prevent overcharging the unprotected cells.
