The SYSMAX Intellicharge i4 is the Universal Charger that you've been waiting for. Compatible with nearly all types of rechargeable batteries it makes owning multiple chargers a thing of the past. The i4 automatically identifies and charges Li-ion, Ni-MH and Ni-CD rechargeable batteries using the correct charging mode. Each of the i4’s bays is independently controlled is capable of monitoring and charging your batteries individually according to their type and capacity. With easy to read LED status indicators the i4 makes charging as simple as plug and go.

  • Simultaneously charge four batteries
  • Each battery slot is charged and monitored independently
  • Automatically detects battery type, status, and ideal charging mode
  • Features three charging modes:
    • Constant Current Charge (CC)
    • Constant Charge Voltage (CV)
    • Trickle Charge
  • Easy to read Tri-Color LED shows battery charge progress
  • Automatically stops charging when complete
  • Integrated Reverse Polarity Protection
  • RoHS and CE Certified
  • Input voltage: AC 110~240V 50/60HZ or DC 12V
  • Input power: 10W
  • Output voltage: 4.2V ±1% / 1.48V ±1%
  • Output current: 375mA x 4 / 750mA x 2
  • Dimensions: 139mm x 96mm x 36mm
  • Weight: 156g (without batteries and power cord)

    • Ni-MH / Ni-CD: AA, AAA, Sub C, and C
Warning! The i4 charger cannot identify the battery capacity itself. So when charging one single 10440 Li-ion battery or AAA rechargeable battery, the i4 still emits about 750mA current for charging, causing the battery to become hot.

- Please do not use the i4 to charge one single 10440 Li-ion or one single AAA rechargeable battery.

- When charging two 10440 Li-ion or two AAA rechargeable batteries, please set them in slot 1 and 3 or slot 2 and 4.

Reliable charger for reliable batteries
June 14, 2015
For my protected and unprotected batteries that range from convenience of rechargeable A's to 18650's batteries this is my go to charger. I have no problems using this charger and I can trust that it won't damage my batteries by over charging. Granted it's a little hard to remove all four batteries from the bay, but you just gotta start from one side to the other side. Simple.

Nitecore Intellicharger i4
May 30, 2015
This charger works well, it performs as described. I use it to charge protected 18650 li-ion cells, I have not tried NiMh or NiCd. If you are new to l-ion cells I recommend this. You can obtain more advanced chargers for more money, but for someone who needs a dependable four cell charger this one provides a lot for your money. Some of my button top protected 18650 li-ion cells are long, and prove to be tricky to install and remove from the charger.
Compatible with many cells
Some cells , protected 18650 are near the maximum acceptable length to fit

Good charger despite cheap materials
March 31, 2015
This is my second i4 charger, I have one at home and one at work. This second charger seems to be a bit less finicky than my first one in terms of the springs. The first one I purchased has very stiff springs, and it can be difficult to position batteries in the charger. This new one works much more smoothly. While it's mostly plastic, and thin metal they both hold up well, and perform the charging duties admirably. The only concern is that if you're charging one or two batteries you have to be concerned about which slots to use, and the size of the batteries, as a single 10440 isn't a good way to use the charger.
charges many types, and methods
must use more than one 10440 at a time, and alternate slots if not fully loaded. This is identified in the literature, but once you've lost that you have to remember these points, as nothing on the charger gives you clues about the caveats.

It charges...but not fast.
March 31, 2015
I needed another fast charger for AA Nimh...was disappionted that it was considerably slower than my other chargers, taking more than 5 hrs to charge moderately discharged new batteries. (my others do it in 20 - 40 min). I will keep it mainly because it would cost me close to $20 in return postage/restock fees etc.. But it does charge batteries, if that is what you need.

I HAVE SEEN new OFFERS of 4 rechargable batteries and a battery charger for half the price if what i paid for just the charger looks like there is a war between major battery makers,and must admit it is a new great deal out there at the big bix stores.
Mabe a good charger
You can find similar chargers out there very recently with 4 rechargeable batters for half the price.Hard to beat and the makers know it..

Excellent, reliable battery charger
January 11, 2015
I have had a Nitecore Intellicharger i4 for a while and recently purchased a 60-pack of AAA batteries, a 12-pack of AA batteries, and several Nitecore 18650 batteries. This charger proved to be a champion! The AAA batteries took about 4 hours to fully charge, the AA batteries took about 6-8 hours to fully charge, and the 18650 batteries took about 8-10 hours to fully charge. No problems whatever. One of the slides stuck initially, but after the marathon charging session, all the slides work perfectly an smoothly. I also bought one of these chargers for a friend for Christmas, along with a Nitecore flashlight and some Nitecore 18650 batteries. So far I have been very impressed with all Nitecore products. I now own 2 different Nitecore flashlights, the charger, and 8 of the Nitecore 18650 batteries.
Excellent, reliable charger

Versatile Charger

I bought this charger and a Fenix ARE-C2 charger. The Nitecore offers the ability to charge Ni-Cd batteries. The Fenix does not list Ni-Cd as supported batteries. I don't own any Ni-Cd batteries and have not tried them in the Nitecore but I like the option. Besides, the Nitecore costs less than the Fenix.

120v plug doesn't fit in the charger.
October 1, 2014
It appears to charge NiCd and Ni-MH batteries, haven't tried the Li-ion's as yet, the great deal on 20 Li-on's just arrived, I'll let you know.
Charges quickly.
I had to use a wall charger, (120v to 12v) I had, as the supplied 120 volt power cord did not fit in the unit's female connector. I don't know why you would need the 3 yellow lights to show the charging process, only 1 to show charging and 1 to show charged would be enough. I'm not complaining if it lasts at least a year. ha-ha.

I love this charger as it has everything I wanted (see Pros section below which is basically my wish list). However, my particular model is definitely overcharging my batteries (Eneloop pros AA and AAAs). I never leave a pair for more than a couple hours at a time and even though it's still charging when I take them off, they are fully charged (usually around 1.55V already). I left one in overnight just to see; the voltage was 1.67V in the morning and the battery was definitely hot so I don't trust this charger for unattended charge. But I have it so I use it on a timer which seems to do the trick.
Built-in power supply (does not require external brick) 4 adjustable chargers independently tracks each battery individually allowing multiple size Charge simultaneously.
Mine overcharges the batteries which is a sad discovery

Terrific Charger
September 14, 2014
This is truly a terrific charger, esp. for the price. I've never had trouble inserting larger batteries. It may take 10 seconds instead of the usual three with AA batteries. Wow, that's a deal breaker alright. I love that it charges all the battery types I own.
Compact, charges a wide variety of batteries, easy to use, good quality.
I had to lube the sliders when I first got the charger becasue they were a little stiff.

5 Stars all the way! This is the one you want...
August 6, 2014
Only four stars? Are you kidding me? This is best battery charger on the market. Second only to its BIG brother, the Nitecore Digicharger D4. The i4 has worked perfectly on everything I have thrown in it. IMR Li-MN, Li-Po, Li-on, Ni-Cad, Ni-Mh, 26650,18650,18350,16340, AA, AAA, and it does more than that. These are just what I have personally put in it! The thing is built really well and with good materials. And I am Super Picky! Not to mention that it works on 12V DC as well as 110 AC. Leave all your stuff in the truck, no need to pack it back and fourth.... if they rank the 12 best this should be #2 with the D4 #1. They didn't even mention the D4 ? If you want the best for the cash without all the razzle of a digital display. this is IT! if not, the the D4 it is.
Does everything, does it well, does it safely and a very reasonable price
The longer batteries (18650) are a little tricky to insert

Charges great ... hard to load 18650s
July 3, 2014
This inexpensive charger charges premium 18650s nicely. However, it is very difficult to load those 18650s, which just barely fit the length of the slot, and the sliding back contact is too short to keep a finger on it, after you slide it all the way back, and then try to insert the battery. It's a challenge every time I charge, and the covering on the 18650s are getting torn up by the effort. I'll just have to find a thin, strong tool to hold the contact against the back wall of the charger while I get the 18650 in the slot.
inexpensive intelligent ... charges, shuts off automatically
very challenging to load 18650s

Bad luck with i4 and i2
April 22, 2014
I have recently (last month) had both the i2 and i4 and had to return both. I purchased them brand new from another reputable dealer and the i2 buzzed and the charge lights flashed wildly and occasionally I could get it to charge if I wiggled the batteries just right. When I returned it and bought the i4 we tested it at their store and it it appeared to work fine however, when I got home and tried to charge some new Eagletac 18650s the charging lights flashed intermittently or not at all on all positions so it was impossible to tell what it was doing. When I returned it they tested it at their store and they were just as perplexed as I was. After doing a lot of research I ended up buying the Fenix ARE-C2 and it is wonderful. Not only does it charge all of my batteries from AA NiMH, 14500, 16340 to my 18650s perfectly, it is also very nice to see the current voltage of each battery as they charge. It is more expensive, but the overall build quality is much better IMHO. I have checked the voltage reading on the display against both of my multi meters and it appears to be accurate. Brands of batteries I use: AW, Eneloop and Eagletac.

Great Charger
February 9, 2014
The first one I ordered stopped charging after 29 days. Battery Junction replaced it with 1 day left on the warranty. I have had the second charger for 1 1/2 years. I\'m currently using this charger to charge Tenergy NiCd 1000 mAh, Efest IMR 18650 2000 mAh and UltraFire XSL 18650 2600 mAh batteries. I\'ve never had any problems with the second charger. It runs cool and is pretty durable. I\'ve dropped it of the coffee table a few times. The contacts are hard to spread at first but will get easier. When this one dies, I will buy another of these.

Very Versatile
October 31, 2013
This charger is really convenient for the multiple batteries I have. AAA, AA C and all the flavors of the rechargeable lithiums. The slide contact for the neg side to adapt for different battery sizes can be sticky if not pushed properly. Once you figure this out, it works flawlessly. If you push it from the \"bottom\" of the L bracket it moves smoothly. Pushing it from the top will cause the bracket to bind and wear out the slide grooves. I have 2 of these chargers for a year now and and they\'re still working fine. The only other thing I found was the battery slots are not quite matched. Slots one and three will put a slightly higher charge on the batteries vs slots 2 and 4 if all 4 slots are used simultaneously. The difference is too small to notice in normal use (.02V to .05V) so I\'ve ignored it. I\'d be concerned if the batteries got overly warm but none of that happens. I assume the delta V algorithm is smart enough to know not to push especially if lithium batteries are being charged.

I\'ve had this charger close to a year now and it works just awesome! I love the ability to see the charge levels of each individual cell. My only gripe like some of the other reviewers is one of the slots, the slide sticks at about 3/4 fully open for the 18650s and it requires a lot of force or pushing down on the slide so it doesn\'t catch. It only happens with one of the 4 slides...the others are fine. Other than that issue it has outlasted all my other chargers and works great!

Works Great
September 29, 2012
I don\'t understand why both reviewers had trouble sliding the contact out. I found it very easy. Insert the negative battery end against the contact and push the contact down it\'s track and snap the battery right in. Simple! I use this for 26650\'s and 18650\'s. Charges great.

High Quality Reliable Charger
August 28, 2012
The i4 Li-Ion is a gem of a charger. It has high quality material and construction. Importantly, it fully charges most all size batteries (needs no spacers) and does not heat itself or the batteries. It has a great multi LED charge indication system showing charge status. You can charge 1, 2, 3 or 4 batteries at once. The only minor problem is that you must slide the contact by finger to fit a battery into the charger, The spring action is balky. The previous reviewer was entirely wrong in his assessment. This charger is tops in charging and has high build quality and materials. Highly recommended.

poor construction
July 7, 2012
Flimsy construction, contacts catch and stick. Inserting 18650\'s requires fingers or tools to force contacts out to full extension, a recipe for short usable life. Charges ok.
