As it appears to just have one integrated regulator, I was wondering if there would be any advantage to it over the Nanjg? Not being a fan of the SOS mode there would have to be some clear cut advantage to using it such as greater efficiency perhaps?
Sorry to drop in, but I was wondering: If this is a direct drive driver, why would it be limited to 2.4 amps? Shouldn’t the output be dependent on the current that the battery is able to supply?
You make a great point, and yes, if it was truly ‘direct drive’ the current delivered to the emitter could be disastrously high (thermal runaway—>poof). Since the input voltage directly influences emitter current I describe these types of drivers (FET, PWM’d modes) as direct-drive-like.
Ok, thanks. I had noted the “-like” in your post, but wasn’t quite sure how to ask if you were differentiating between “direct drive” and “direct-drive-like”.
So, if I’m understanding, the way that this driver would be characterized is:
- Output current to emitter decreases as input voltage decreases, and
That driver has no current limit. It’s about as direct drive as you get. The only thing that will limit current is battery voltage, spring/wire resistance and the RDSon of the mosfet.
If their specs are to be trusted it will be in the neighborhood of 2.4A. FT is traditionally better at actually testing their drivers than other budget vendors, but they’re still not infallible.
Edit: Exactly what PPTk said. Current draw from a fresh cell will vary between hosts, so YMWV.
