I use this charger for 18650 and AA b...atteries and it charges them fast. If you like details then The display tells you all the info you will need, including charge rate,voltage,and mah. battery type Easy to read the display and nice and bright If you are not technical then this is great as you just put the batteries in and let it charge, it will stop charging each battery when it is full so it wont overcharge any of them. It also tests the battery and auto selects the best way to fully charge it, this means you get more life from each battery as it does not just charge it at full power. You can also put 4 different types of battery in at a time if you want and it will charge each accordingly It also comes with a figure 8 mains lead, no plugging into a usb charger, just straight from the mains For noobs or tech's this charger has the info and ease of use you will want

The packaging states will charge ...AA and AAA, this in my experience is false. AA and AAA do NOT fit properly and will not charge. If you put a battery in slot 1 it might indicate empty, and if you put the SAME battery in slots 2-4 it will give different readings for each slot, which indicates that this charger cant differentiate an empty battery from a fully charged one. Flimsy build and in my case worthless.

I had the old version of this because I ...use the Boirut Head Lamp and you can't by the batteries so you have to charge your head lamp via USB or headlamp charger and after a while I was getting false charging times so I decided to by the Tomo charger & that made life easier and qucker at charging batteries.When I saw this I thought to myself an upgrade and yes I purchased it.The reliability for charging,the multi charge for different batteries is excellent (as the Tomo didn't have this feature.)I'm glad I bought this charger saving money buying batteries and having them shipped from China that in it's self was a long wait especially in my type of job when I need my head lamp the most.As for the price yes that was reasonable and with the extra's on the charger money well spent.I rehomed the Tomo to a friend as she uses the same set up as I do.

Had an older version of Nitecore charger for many years, fin...ally failed. Upgraded to the Nitecore i4. I have been using it for a short while now and can say that the quality and ease of use is excellent. Batteries are very easy to insert, status display is clear and easy to view. When I have charged 4 batteries the unit is cool to the touch. When charging 4, followed by a further 4 the unit becomes quite warm. I don't really see this as being a problem or a fault. My overall opinion of this product is that Nitecore produce well built, quality products.

This has to be the best multi- battery charger I ...have ever owned. It charges everything from AAAA to 26650 faultlessly ! It has a function which charges at 1.5 A.... Super fast!...Charges 4 batteries at once, and they can all be different voltages, types and capacities in each slot, does it automatically! The only one you'll ever need!
