I also am a fan of the Rofis MR50. Before I used the LedLenser M7R. But because I am using flashlights on the go, I don’t want to use a dedicated flashlight charger. That is why I bought the Rofis MR50 that I could charge with a universal micro usb. Besides that I also liked the fact that it used a 21700 form factor battery with 5000 mAh in comparison with the 18650 2200 mAh from the LedLenser M7R (even though a 21700 battery would fit inside).

A few weeks after using the Rofis MR50 I started noticing that it drained itself. I am only using it about once every one or two weeks. At first I didn’t think much of it, but then I fully charged it and left it for a weak on my desk without using it. After that week it was empty. So I took my multimeter and saw that it always draws around 25 mAh of power. Maybe this is for the powerbank feature to automatically start charging? I don’t know, but it is very annoying. I rather have a long standby (power off) time than a powerbank feature. My LedLenser works perfectly after one month of standby time (power off).
