A decent charger for the money, does not come with 12v car adapter.
When reading reviews, DO NOTE if the reviewer has the "New i4" charger. Amazon has lumped both versions, the original i4 and the new one together in a big mess of reviews. I have the New i4.Charges at a reasonable rate. It does under charge 18650s by a tiny bit, so a 3.7v battery is about 4.17v - 4.18v instead of its all out maximum of 4.2v. Do note, charging 3.7v batteries over 4.2v is DANGEROUS, so I can easily see why they are sticking to the safe side. As a side note, lithium ion batteries do benefit from being undercharged in that they will last a bit longer.It does have a 12v port to use instead of the regular 110v figure 8 power cord. It does not come with a car charger and honestly, I do not see a point to using this in your car, it does not charge batteries nearly fast enough to be used as a portable charger and leaving it in your car unattended is super sketchy dangerous. However, if you are hesitant to connect 110v to a pair of bombs (18650s), you can use a standard 12 volt 3.5" desktop external hard drive power supply to run it. The barrel jack it needs is identical to what those hard drives require. Any 12v 1+ amp power supply with center positive barrel connector is all it needs. This should also be the same as your router/modem uses if it is 12v, but those usually run at sub-1 amp, so avoid those.Batteries in the pictures are Panasonic flat top (non-protected) batteries, which require a smart charger like this one to protect from overcharging. Pictures show it working in the provided figure 8 cable and from one of my 12v 2a wall warts.

It works, but it's slower than molasses
I've had this device over a year and it is easier and more convenient to just buy new batteries. For instance,1. It generally takes 8 plus hours or more, to charge a battery that is slightly but not completed discharged.2. I have charged batteties with this charger, removed the batteries from the charger and reinserted them to see if the charger recognizes that they are charged. It doesn't. Even with fully charged batteries or batteries charged by this charger, it takes several hours for the charger to recognize they were just charged two minutes ago.3. For batteries that are dead or nearly dead, 12 hours charging time is not unusal. You get slightly better charging time if you only charge one battery at a time.4. These times are for charging AA battrties, I can't imagine how long it'd take to charge out-sized batteties.

Overheating batteries and Charging unit itself too
Pro : Low price ,nice looks,convenience,Nitecore brand (My favorite brand).multi size batteries compatibilityCon : I have a D2 which I bought 3,5 years ago and still going strong.Decided to get 4 battery charger for new recharge Eneloop AA so I bought this new I4 .First charging test was with 4 brand new AA Eneloops ,took over 5 hrs and still got only 2 dots ! .Swap out 2 batteries to my old D2 and the D2 finished in about 1/2 hrs since the I4 still cooking the 2 remain batteries(Yes the batteries inside I4 was super hot and the I4 itself too)Conclusion : Returned the I4 ,ordered D4 .Got the same good result from D4 as D2Thanks Amazon for the easy return.

Good value, highly versatile, but a minor drawbacks for AAA rechargeable users.
I ordered this to charge AA and AAA NiMH batteries, though it will also charge NiCd, "C" size, and 3.7V Li ion rechargeables. I've charged about 50 batteries so far, and I find this charger to work well and I consider it a good value. It does have minor, but noteable weaknesses. The i4 detects the type of rechargeable automatically, and charges appropriately. When charging 2 batteries the charging rate is 750 ma, and 375 ma when charging 4 batteries. AAA batteries typically take 1-2 hours to charge, and AAA take 3-6 hours. The charger has 3-bar LED's above each slot to give an indication of charging status. The charger stops charging when the battery is at capacity. Each of the charging slots acts independently (ie, I just charged 3 AAA and 1 AA at the same time), but there are some limitations with AAA batteries.Nitecore recommends that you do not charge a single AAA battery alone, and if you do charge 2 AAA's at a time, its recommended that you put the batteries in slots 1 and 3, or 2 and 4, to avoid overheating the batteries. (From the manual: "Nitecore strongly recommends that AA, AAAA and 10440 Li-ion batteries are not charged alone in the i4 charger. When using only one charging slot, the i4's current automatically sets to 750mA, which exceeds the maximum current range of most AAA, AAAA and 10440 Li-ion batteries. .... it is recommended that a minimum of two (2) AAA or 10440 rechargeable batteries are placed into the charging slots together. When charging two batteries in the i4, be sure to always place them in either slot 1 and 3 or slot 2 and 4" The four charging slots are fairly wide, but not really large enough to fit C size batteries. AA batteries fit into the charging slots well enough, but AAA batteries tend to slip left or right off of the terminals if bump the charger. I don't use C rechargeables, but I would note that C size batteries barely fit well enough to reach the terminals, and you can only fit in 2 at a time. This product listing says "2X EdisonBright AA to D battery converter spacers included", but they were not included with the charger I ordered (Amazon promptly addressed this problem with my order by offering a refund)

Well thought out, flexible design
I got this as a gift to go with a set of six Moobibear 18650 batteries (Li-ion) for an e-cig mod that use three batteries at a fairly high discharge rate. I selected the charger because it monitors the charging of each cell individually and shuts off each cell as it reaches full charge. The cells I purchased are all matching and rotated in use as a set. So far so good. This charger gives me some reassurance it's as safe as I can get at this time.
