Nitecore Intellicharge i2 2-Channel Smart Battery Charger

Reliable and Versatile

The Nitecore Intellicharge i2 Smart Charger is a brilliant accessory for any rechargeable battery user. Capable of charging a wide range of Lithium and Nickel-based rechargeable batteries, the intelligent i2 automatically identifies the chemistry and size of the inserted batteries and applies the appropriate charging mode (Constant Charge Current (CC), Constant Charge Voltage (CV) or Trickle Charge). The advanced processor-controlled charging slots are even capable of charging two different battery types at the same time, allowing for greater flexibility when charging. Above each charging bay is a handy 3-LED display that will allow you to monitor the charging progress of each inserted battery individually. The charger itself is constructed using ABS fire retardant plastic and comes standard with reverse polarity protection, making it as safe as it is effective.

My first Li-ion Charger
Have had many Ni-Cad charges, this is my 1st Li-ion. Simple and easy to operate. Does everything as described in the product description. Purchased with Nitecore RCR123A Li-ions. Everything works fine, just as expected.
ProsPop batteries in, check on indicator lights, so easy
ConsNone so far

Simple, but does the job
I have the Nitecore D4 charger already, but the i2 charger came as a package deal along with two 2600 mah 18650 batteries when I bought the EC4S. The i2 works fine. The unit gets a little warm, but not hot. It can charge one or two batteries at a time and the unit shuts off when charging is complete. The D4 is nicer due to its digital display, but for the price and functionality, the i2 is more than adequate. Plus, now I can charge SIX batteries at a time. I'm happy with the unit.

Fast and useful charger.
This site http://lygte-info.dk/review/Review%20Charger%20SysMax%20i2%20UK.html is what made me buy this charger. It is super easy to use. You drop in the batteries and just wait for the LED's to stop flashing. It cannot get any simpler. It accepts a variety of batteries and works fast.

Nitecore Intellicharge i2.2

Great little Charger
Just got it the other day and charged all of my 18650s that needed it. The ones that were already charged were indicated thusly within ten seconds or so of putting them in the charger. The series of three lights to indicate charging progress are quite helpful in figuring out how far along in the charging process the batteries are. The fact that each battery is independent of the other as far as charging goes is a great feature. Haven't used it for long but like it a lot so far. Feels like it is solidly constructed and should hold up well under long term usage. It's not fancy, just functional. I like that!

One very cool charger!
And it is cool...to the touch. I charged 12 Eveready "AAA" and "AA" back to back as soon as this charger arrived. The i2 never got hot. The batteries were new so had some charge in them. All were fully charged. This device is intelligent enough to know what battery you insert and charge it properly. That is as good as it gets....Oh, and the great price. You can use this in car or home!

Works as advertised.
The smaller type AAA or 10440 batteries have to be positioned in the charger just right or they won't make contact and are easily knocked out of position. Other than that it works just fine.

Great Performer at a Great Value
I read some very extensive, expert test reviews on this unit before making my purchase, and learned that it's a great performer! I didn't currently have the budget to pay for a lot of "bells and whistles", such as digital displays, etc. I simply needed a great performing, safe 2-cell charger for my flashlights and new lasers that would provide good charges to my cells without being hard or harmful to them. This charger is EXTREMELY simply to use and understand, and does it's job well!
ProsSimple to use. Safe, and does it's job well. Charging times are more than acceptable. Doesn't overcharge or heat up your cells.

Practical to charge from solar collector
Finally found one. I have a 20w solar tri-fold that charges everything excelant except this one item missing and now I'm covered. When the grid drops and we have all these recharables I can charge mine. Thanks for this simple and perfect item. Oh yeah and it works great.
ProsNo outlet required.

Simple to use and fully automatic
The AAA rechargeables came to full charge in a couple of hours. The charger is quite simple, but by no means basic, owing to its ability to detect and charge batteries of several chemistries.
ProsLights indicate full charge and blink as they are charging. Will not overcharge batteries and will work unattended.
ConsInserting the AAA Ni-Mh batteries requires just a bit of dexterity because they must be placed high in the sockets. They don't make contact when placed at the bottom of the slot. Ni-Cd batteries are an older technology and are larger in diameter; these will occupy the full diameter of the charging slot.

Awesome 'universal' smart charger
What a great deal on the i2. You're able to charge multiple types of batteries from AAA to 18650's. The i2 is as able to tell the type of battery in each slot and charge independently. It knows how much current to go into each slot and automatically stops charging when each battery is full. Instead of AC power, you can buy the $5 cigarette lighter' adapter and be able to charge batteries in your car. High quality unit and built of flame resistant plastic.
ProsPrice, quality, able to charge a high variety of batteries.

My first charger
So I got this charger with a combo, and it's the best investment anyone can make when buying high quality equipment. I've charged rechargeable AA's, AAA's, 18350, and 18650 batteries. I have had no problems what's so ever; it's all how you insert them that's the trick.

Gets the job done in a decent time frame
ProsCharges the battery full and shows a nice display to let you know when its finished. Wont overcharge the battery once its full.
ConsThe rolling mechanism that holds the battery into place, if you are not careful will chew up the batteries. So to avoid this, push it back by hand then place the battery in the charger.

Quality battery charger
Only used it a couple of times at this point but it works as advertised. Further use will be the deciding factor if it holds up but I am betting that it will. Quality products rarely let you down.

Got it at the right price
Received my charger last week and put in 2 18650s that I received in the same order. The charger worked fine but it must have been on the Trickle Charge, it took about 7 hours to complete the charge so plan ahead when you use it. I like the fact that it will charge 2 different battery types at the same time. It fits my needs well so for the price I give it 5 stars.
Pros price, auto off, versatility, size
Cons none so far
