    Two types of input, AC 220-240V or DC 12V. Can charge different types of lithium batteries. Independent charging lines, so you can charge only one battery independently. It doesn't include the AC 220-240V cable. Side contacts to charge the 16340/CR123A batteries are not soldered, so you need to I... Read more

    It mostly works and is good for its price, can be used with any adapter giving 12V @ ~500mA or It came without power cord, and I had to make some rapairs (A coil wasn't properly soldered), and my 18650 did not fit (a milimeter too large), so I had to make an adapter. Also, the fixed size contacts... Read more

    Can charge various types of lithium batteries. There are two inputs 12V DC and 100-240V AC. Independent charging lines. You can charge one battery or two at same time. Side contacts for charging 16340 not work. So, you need to solder them manualy. Poor solder quality at all. PCB is dirty. There... Read more
