Couldn't pass up this charger. It will charge every type of battery that I use on my devices. I have two other older chargers but they won't charge the new battery types. Now I have one device that will safely charge every type of rechargeable battery that I have. I was concerned about Li-ion batteries exploding but this charger monitors the recharge to prevent that problem,

What exactly do the blinking lights mean? When it is finished charging the lights will show what? "Press the C button to select a slot" - how do I know which slot is selected? How exactly do you change current and voltage settings? The instructions do explain this but not in any way I can make sense of. Do you have to be a Chinese electrical engineer to figure this thing out, or am I just too stupid to charge a few batteries? So I put my batteries in this for a few hours and hope that they are charged, other than that I cannot understand who would think the user guide was adequate for this product!

The charger works. We did no need the extra modes but a satisfied.

My 2nd one. During a last big storm it took me a while to charge all my batteries. The batteries get a little bit hot by the end of a full charge. I chose to stay with my same charger rather than one that may charge faster. Think I have 6 nitecore flashlights and 3 chargers.

The charger works fast - charges 16 batteries in a very short time!!

I HAVE MANY MANY DIFFERENT KINDS OF .......AA, AAA, LITHIUM ION....THIS CHARGER CHARGES THEM ALL! VERY EASY TO USE TOO! YOU PUT YOUR BATTERY IN AND IT DOES THE REST! A GAME CHANGER FOR SURE.....THE DAYS OF HAVING DIFFERENT CHARGERS FOR DIFFERENT TYPES OF BATTERIES ARE GONE!

This charger belies it's small, simple look by being the best charger I've ever had! I just replaced my old charger and that one didn't work very well at all. This is well worth the money to 'top off your list'. Great charger!

Great charger for many sizes of small batteries.

Got this as a gift for a friend. She tells me that it would not charge the batteries consistently, often leaving the batteries half charged. Then, she reported a melting plastic type smell coming from it & found it hot to the touch.

This is one of the best chargers I have used, worth every penny.

I have owned previous Nitcore chargers in the past with great results. Bought this one for a gift. The person that received this is extremely happy with it. Cons: none.

This is a great charger, it can charge different types of batteries

as advertised

The technology is great feel very safe using it and for my battery's this thing preety smart. Coil charger.
