Summary

The Manker E05 II is a compact EDC flashlight, supporting Li-ion and NiMH batteries. It has three levels of brightness with constant output for most of the runtime. The mechanical tail switch makes it easy to use.

Waterproofing of the switch is a little questionable, though. Better don’t try to press it under water.

You can get the flashlight in various colors and materials. You even have the choice between different LEDs (get the Nichia 519A version).
