Easy Thrunite BSS W1 Operation

The W1 has a very basic user interface.

Click the switch once to turn it on, and again to turn it off. Pressing and holding while it’s on will cycle from low to high.

Firefly is hidden and requires a holding press while it’s OFF, to activate it. One click from firefly turns it off.

Turbo needs a double-click, which works whether it’s ON or OFF.

Strobe needs a triple-click…from ON or OFF.

Illuminated Switch

When switched on, illumination within the right side of the button will be blue (as long as the voltage is high enough). It’ll be red (or flashing red) if and when voltage drops significantly.

Similarly, when the USB cable is connected, the button will show red during charging, and turn blue when completed.

Let’s Sum It Up

First off, there are dozens of tiny EDC flashlights out there. So, the sizing of the Thrunite BSS W1 isn’t enough for it to stand out. Having said that though, the size makes it very convenient.

What about features?

Thrunite W1 and battery

With the included 16340

Pretty good.

It’s USB rechargeable. It has a magnetic base. It has an illuminated power switch. Those three combined elements help to set the W1 apart from some of its competitors.

Another convenience is the inclusion of a 16340 rechargeable battery. No…the don’t last terribly long, but when using the light on medium, you’ll get fairly good runtime, and the battery doesn’t take long to charge. And speaking of charging, the W1 internally pumps 500mA into the battery…which is both fast, and safe for a 16340.
