Nice universal charger – UltraFire WF-139 3.7V 14500/17500/18500/17670/18650 Battery Charger (AC 100~220V/DC 12V) Reviews

Pros:
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.
Cons:
Side contacts for charging 16340 not work. So, you need to solder them manualy. Poor solder quality at all. PCB is dirty. There are flux residues.
Other:
This sku comes with car 12v adapter and without AC plug. But you can easily use power cord from another device. Power cord from my netbook's charger fits nicely :)
Bottomline:
Good universal charger. But it needs refinement.
