Klarus C8

Charge ALL of the batteries

For users in need of serious bulk charging power, the Klarus C8 has what it takes with 8 individual charging ports and the ability to charge all of the most popular rechargeable battery models. The C8 can power up a wide range of Li-Ion, NiMh and NiCd chemistry batteries including 18650 and 16340 sizes. The C8 is a smart charger that detects the voltage and capacity of inserted batteries and charges them accordingly, assuring that no over-charging occurs. Each charging port features an individualized LED charging indicator that lets you know when a battery is charging and when it is ready for use. With its large battery capacity and lightweight portability, the C8 is a great choice for people who are on the go and need to take their energy solutions with them!

  • Microcomputer control system allows each of the two battery slots to charge individually
  • Capable of charging 2 batteries simultaneously (Ni-MH/Ni-Cd/ 3.7V Li-ion)
  • The LEDs will clearly display the charging progress of each battery
  • Charging voltage is from AC100V to 240V or DC12V, safe to use on all power grids in cities worldwide
  • -dV/dt Control technology to charge Ni-MH and Ni-Cd batteries more fully
  • Built-in reverse polarity and short-circuit protection
  • Features over-charge protection to prevent battery damage. Automatically stops charging when complete
  • Auto-activation function:
    • Automatically reactivates "zero voltage" short-circuit protected Li-ion batteries that have been completely drained of power
    • Three corresponding indicator lights will flash simultaneously when attempting to charge a battery that cannot be reactivated
  • Made from durable ABS (fire retardant/flame resistant) for your safety
  • Designed for optimal heat dissipation, long lifespan
  • Please Note: All bays are capable of charging simultaneously, but you may be limited in charging eight C-sized, or larger, batteries simultaneously due to the large size of the cells.

Nice Charger, Great Price
I'm giving this review five stars, but be aware that I've only had the charger for one day. I like that each battery charges independently and have their own status LEDs. I also like the integrated USB charge port.

There was mention in other reviews that suggest this charger should be able to work within a car and I believe those reviewers are mistaken. Klarus does not supply an automotive adaper cable, even as an optional accessory. It is true that the charging unit itself uses an input voltage of "12VDC at 3.5 amp". The unit's power supply provides that output from 120-240VAC 50/60Hz and has a removable US 120V plug cable. One could use a european AC cable (not provided).

Note that autos do not actually provide "12vdc", they provide 13.8vdc when the alternator is running and 12v from the battery when the engine is off. 1.8 volts is a significant difference, almost 15%. A 12 volt-regulated at 3.5 amp from 15vdc, or 120v inverter would be needed to run this in a car or damage to the internal charging circuitry might result.
In reality, a 2 cell or 4 cell charger would be more useful in a car...

Other comments were made about some minor difficulty aligning the batteries to the charger electrical contacts. Now that I have the charger, I understand this issue. The cradles are sized (naturally) for large-diameter "C" cell batteries - the biggest (physically) battery that can be charged, so smaller diameter (18650 & 16340) batteries do not fit snugly. Also, positive contacts have a rather severely pointed contact shape that mates with the battery's small '+' contact. The pointed contact is designed to make an excellent electrical connection, even with batteries that might be a little bit corroded from use 'in the wild'. It's not a problem in the least and you have the status LEDs as another indicator of correct installation.

I plan to get at least one more of these, and a 4 cell unit to use in the car.
ProsExcellent design - I'm very impressed with the thought, experience and engineering that obviously goes in to Klarus products.
ConsI want more... (Those of you who get adicted to cool kit will understand.)

Battery charger
Purchased for my scout troop. This charger works well and charges both 18650 and Ni-MH cells. It came with an AC adapter but literature indicated that it can be connected to a 12VDC source and it did not come with an adapter for that connection. I have not tried to charge Ni-Cd cells so I have no information on that type of battery. The Ni-MH AA cells that I charge took a little fiddling to get the positive post on the cells to make connection with the charger but they charged after that. The NI-MH cells were quite hot after charge was complete, (this may be normal), but the cells worked after charge.
ProsCharges most types of rechargeable batteries Monitors each battery under charge individually
ConsDoes not have a 12VDC adapter

Have 3 works as expected
Almost all batteries charged are 18650 L-ions, Bought 3 because I have to charge at least 24 at a time. I rotate my batteries (over 60) in the 3 chargers and have experienced no problems, batteries do not get that hot so I know it is charging properly. I sample some of the batteries on another charger showing me charge info and batteries are within spec so charger must be doing its job.
ProsCharge 8 at a time, decent charge time, works well
ConsBatteries sometimes feel sloppy in the holder not centred, just be careful to centre them gently.

8 bay cell charger & hot battery
I am concerned about how hot the batteries have become during charging; I have tested various AA , AAA, and C size nickel-metal-hydride and found each cell nearly too hot to hold after charging is complete (3 yellow leds are on, under 3 hours typically). I will not test 18650 batteries until I resolve the safety of this charging device. I suspect it is similar to 0deltaV charging, which does get the Ni-MH chemistry up to 130F when "fast" charging under 3 hours, but that is not stated on the Klarus C8 package or its instruction sheet. It also does not fit 8 C-cells very well; you have to move the batteries around to make contact as the placement of 8 C-cells seems to be too much for the charger's physical design as cells push against each other and force some out of contact with the charger's contacts. Overall, however, it is working.
ProsSeems to charge very thoroughly; each battery bay operates independently of the others. Fairly compact size; uses external 12V DC, 3.5A transformer (runs warm).
ConsBatteries become very hot; too hot to hold in bare hands. Don't know if the heat could be damaging the battery chemistry prematurely.

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.
