Nitecore Universal Smart Charger 2 Ports UMS2 Adult Unisex, Black, L: 152 x W: 73 x H: 40

Your regular battery charger won't charge 30T batteries. This works well and gives plenty of information about your batteries' condition.

Charger is good - provides useful information about the health of the battery and state of charge, and allows a level of adjustment. Packaging was slightly damaged - inner plastic packaging was cracked badly. Also looked like the product had previously been removed and cable unravelled.

This product is excellent you can set the charge current in 100mA steps up to the maximum, lots of information on the display, Voltage, charge current, battery capacity, charge time etc.But I have two minor niggles,1, Some AAA wont connect to the -ve terminal if the battery has a flat base.2, you must have a Q3 (Qualcomm) usb power supply to use the high charge current features.

One of the quickest chargers around

The description does not state what type of sun port this has. Unfortunately it uses Micro USB.

What a great little charger. I own quite a few torches and some of the batteries are quite old. This charger sorted them all out! I would highly recommend this charger.

I ordered this charger to charge up a couple of i Series Nitecore 21700 batteries. On opening the box it looked an excellent charger, well made, and I have read that not many chargers will charge up the i Series Nitecore batteries, also after reading reviews, Nitecore chargers seemed well respected, excellent and reliable chargers. Nitecore do specify this model of charger as been been able to charge the i Series batteries, so I thought what better charger to get to have full compatibility.I connected the USB cable to a power source (one that I can confirm is working, and also I tried the a AC USB wall adapter plug with a different USB device again that I can confirm is working) but absolutely nothing happened. The screen did not light up, it was totally dead. I can confirm that all the cables were fully inserted.I raised the return and ordered a second charger and put it down to that I have received a faulty charger (it does happen I suppose).The second charger came and it was exactly the same as the first, i.e. plugged it into the power source and the charger was dead, the screen did NOT light up. And again confirmed that all the cables were fully inserted, tried to power a different USB device (and again the other USB device I tried worked, so I know 100 percent on both chargers that it was down to the chargers been faulty).I think that there must be a bad batch of these chargers. I am now in the process of returning the second charger, and I will ask around and see if I can find an alternative charger that will charge up the i Series Nitecore batteries. It's certainly put me off ordering a third one, as this should not be needed to be done, on a charger of this price.Hopefully I will find an alternative that actually works out of the box!

Good
