Review Summary

I used for charging AA nickel metal hydride batteries. I charged eight batteries at a time, for a total of twenty four batteries. The charger 'quit' on the next set of eight batteries! I used a volt meter to analyze the problem! DOA Nada! Nothing! Sent it back, and NITECORE Store substituted TWO I4 chargers! Thank You NITECORE Store (David) for taking care of this minor problem!

I already had a 8-slot charger and loved it. It charged my batteries quick and lasted about 6 years and I'm confident that it would've lasted even longer if not for poor handling of my checked bag on a domestic flight. Nitecore makes a quality product and I would highly recommend buying one.

Works great and doesn't take up much space for an 8 battery charger.

I plugged the charger in and installed some batteries and two minutes later it cut off and that was IT!

So far working great with all my 18650 battery charging needs. Delivery was fast and product came in undamaged and ready for service. The red and green led lights make it easy to see when the battery is charged. I feel it is faster than my Nitecore 4 battery charger, but I haven't measured it with a watch, so I am not positive.

Upgraded to the 8 bay charger from the 4 bay charger and so far I?m a big fan. This one Charges 4 batteries much faster than my 4 bay charger and has room left for me to charge all my batteries if ever need be

I dont like change, but I really like this stand up charger. I would have been fine with flat 6, but wanted to try something different. All the nitecore chargers I've had worked perfectly. Keep up the great work!

Bought this charger years ago when it first came out. It charges pretty fast and the fact that outlets are sparse or hard to reach in my house; having the USB ports to charge mine and my wife's Android phones is quite handy. My only gripe is that I have to stagger my 26650 batteries with her 186650 batteries so it does make charging more than 4 266650 difficult. Only recently have I started looking for another charger because this one is dying and has a ticking sound like a clock when charging. Was hoping to find another one but they are discontinued. I hope they re-engineer this one to be a little more accommodating for multiple large batteries.

The vertical battery seating between the terminals are not a secure fit for AA or AAA batteries, you need the hands of a child to fit each battery in its charging position. After using this device for six months im thoroughly sick of batteries jumping out of their position and picking them up from the floor, worst designed charger in existence. The USB charging function does not charge android phones.

Bought this item to replace the non-working one which I dropped! Very happy with the performance and working of this product.

I have a lot of solar lights out back and I can keep all my lights going strong even on cloudy days thanks to this battery charger. I've already used it charging six AA batteries at a time and only took about an hour to charge all six.

I love how this battery charger can charge 8 cells at a time, but there is draw backs. Due to the fact that this charger can support the larger and wider cells, it can't hold smaller cells really well including my 18650s used in my flashlights. There is some wiggle room, so you have to keep it stationary or else it will most likely break connection. There goes my wish of using this in a car.

The only thing is that the springs are a little lacking w regards to 26650's.don't hold them tight,tight. Enough room,but a balancing act. 18650 ok.20700 ok. Haven't tried D batteries yet,but I don't feel they will hold any better.

Pros: Will recharge 8 cells. Each battery is individually charged. Cons: 1.5A limited to 2 cells. 0.75A x 4, 0.5A x 8 LED charge status lights very dim.

Works ad advertised, would get 5 stars if it had displaying showing whats going on, red charging , green charged doesn't tell you much, but most of the time that's all I need

It's a charger, it works. But it charges a bulk load of batteries which is a good thing when you have so many items that take rechargeable batteries. Plus, it takes no more room than 2 and/or 4 bay chargers. Well done, Nitecore!

Compatible with and identifies Li-ion batteries. Ni-MH and Ni-Cd rechargeable batteries
Features three charging modes (constant current, constant voltage, -dV/dl)
Automatically detects power level of batteries and selects the appropriate voltage and charging mode
Automatically stops upon charging completion
Over-charging prevention
Reverse polarity protection and short circuit protection
Activation function for over discharged protected batteries
USB output
Designed for optimal heat dissipation
Made from durable PC material (fire retardant / flame resistant)
Certified by RoHS, CE, FCC, CEC
The i8 is distinguished from traditional multi-slot chargers, saving room on desktop
Charging speed up to 1500mA in a single slot
Monitors and charges each of the 8 slots independently
Active Current Distribution
Automatically detects power level of batteries and selects the appropriate voltage and charging mode
Designed for optimal heat dissipation
Supports USB output
Charges and controls 8 Slots Independently
The i8 can charge 8 batteries simultaneously. which is time-saving and efficient.
Active Current Distribution, Fasten charging speed
The ACD technology allows the i8 to actively distribute its power among 8 slots in an orderly manner. For instance, when a battery is almost fully charged, the charger will divert a portion of its current to charge other batteries.
Simple Operation, Easy to Charge
Red indicator - Charging in Progress, Green indicator - Charging Completion.
Automatic Detection on Power Level and Selection of Charging Mode
After batteries installation, the i8 automatically detects power level of batteries and selects the appropriate voltage and charging mode.
dV/dt charging function
The -dV/dt function specifically for Ni-MH and Ni-Cr batteries, which can detect the battery status and judge the timing to terminate charging, aims to charge Ni-MH and Ni-Cr batteries as full as possible but not overcharged.
Reverse Polarity Protection and Short Circuit Protection
If there are batteries inserted with polarity reversed or short-circuited, the red indicator of the relevant channel will blink quickly to notify users.
Battery Activation
The i8 is capable of activating depleted Li-ion batteries with a protective circuit. After battery installation, the i8 will test and activate the battery before charging.
Overtime Prevention
The i8 has overtime protection. It will individually monitor the elapsed charging time for each battery slot and if a particular slot exceeds 20 hours, the i8 will automatically stop charging and the green power indicators will illuminate to indicate completion of the charging process. This feature reduces the risk caused by batteries of lesser quality.
Safe Mater
i8 is constructed from flame retardant and fire resistant PC materials aiming to extend the lifespan and ensure safety.
