I am very interested in the EagleTac T20C2 for my mountain bike, because I need that the cars see me when I go in the streets at night (I use my LD10 in the helmet). Also I will use it to enter me in the world of the flashlights with CR123 batteries (very difficult to find in my country). My only concern are the batteries and the charger. I saw this charger in Amazon:
But some people speak about malfunctions and poor runtime in flashlights. Someone has tested this charger or he knows one similar that can also be connected to a 12V car cigarette lighter? This is very important to me, because I intend to use it to leave camping and to connect it to a solar panel (in the next months I will go to my third trip to the desert and NEED this option) and in a quick search in the forum I did not find an answer to this characteristic.
Thanks in advance. Greetings from Chile.
