Cheap ($5) aluminum LED flashlight powered by 18650 LiIon cell. Marked as model 910.
Switch with rubber dome is on the bottom. There are two blinking modes and 3 constant modes with different power, it looks like it to switches to next mode with each press, but there is also some timeout after which previous mode is kept. When measured with ohmmeter this looks to be regular mechanical switch, so control electronics is in the body, probably near the LED.
Actual measured current consumption (with cell voltage = 4V):
- 850 - 950 mA in "high" mode with constant light
- 430 mA in "medium" mode with constant light
- 250 mA in "low" mode with constant light
- about 450 mA in fast blinking mode
I'm measuring 0.3 Ohm ON state resistance for this switch which is little worrying (maybe a room for improvement?), though maybe this is partly poor contact for multimeter probes, aluminum and springy element inside the cap (but for clarification this is not related to probes cable / probes itself, I'm measuring this as relative resistance).
This 18650 charging cradle is actually empty - it is just a socket with direct connection.
Suspiciously light 18650 cell. Probably not worth much, I wouldn't be even surprised if this would be fake cell with regular AA inside. Be prepared to replace it with something more reputable. There is plastic sleeve included as flashlight body is slightly wider inside than the diameter of 18650 (maybe this is also for short circuit protection?).
There is additional 3xAAA holder for alternative power.
Quite a lot of light output, here with maximum "ZOOM OUT". I believe this might be a 3W LED (current consumption confirms it). Small beam on the right is my smaller flashlight powered by single AA cell (https://commonemitter.blogspot.com/2017/12/099-mini-flashlight.html).
At maximum "ZOOM IN" lens position light beam (at focus point) is identical to LED structure.
