The Nitecore TUP is a milestone among key ring flashlights. With 1000 lumen maximum power, an OLED display and an integrated Li-Ion battery with 1200 mAh, the TUP leaves nothing to be desired. The display informs about the light output, the current battery voltage, the remaining running time and the selected mode. Operation via the two switches enables control of the five light levels (1000/200/65/15/1 lumens) as well as direct access to Turbo and Low. With two-stage switch lockout, which optionally still allows direct access to Turbo or secures the lamp completely. Two operating modes selectable (30 seconds auto-off or manual switch-off). Black aluminium housing with USB charging socket, removable stainless steel clip and key ring with carabiner.
