I would get something like the xtar WP2 II once for about 20 bucks and be done with. The quality control on TrustFire stuff is iffy at best. There are more reports on ECF of late of recent TR001's never getting to proper charging volatage. 18650's taking 10+ hours to charge in the process, and/or the battery getting close to 4.2 volts... but the charger isn't completing the cycle and stays stuck on a red status LED. Take the charger back, try another one... same problem. You can only cheap out so far on chargers and batteries before you buy more problems than save any real money. And the xtar stuff comes with a 2 year warranty.
