  • Simply too hot!

    Involvement:Expert (understands the inner workings) - Ownership:less than 1 day

    Pros:

    Good Price

    Easy to use

    5 mode

    Able to handle 2 li-ion cells

    Cons:

    NO memory

    Simply too hot.

    Low Efficiency of 67.5%. 7.4V input (8.6W) only results in 1.845A @ 3.15V output (5.81W). This means that 2.79W of energy will become heat in the driver which makes the driver heat up really bad within seconds. I couldn't put my finger on the driver for more than 2s after 20s on high. I wouldn't recommed this driver in any torch light unless you like a torchlight that can warm you up.

    Bottomline:

    Good for testing but don't get this driver for your torchlights. Too hot to handle.
