On-device Settings

Compared to their previous 3395 wireless releases, VAXEE has partially revised how settings are adjusted on the E1 Wireless. Instead of three buttons for CPI, polling rate, and button debounce time, there now is only a single button, which changes functionality when pressed and held. This way, one can adjust CPI (400, 800, 1600, 3200), polling rate (500 or 1000 Hz, with 2000 and 4000 Hz being exclusive to wireless operation), and button debounce time (0, 2, or 4 ms). In addition, MotionSync (on/off), lift-off distance (low/high), and competitive mode (on/off) can be adjusted by keeping two buttons pressed while turning the mouse on. Note that this is only possible if the mouse is not plugged in for charging. Selecting 2000 and 4000 Hz is only possible if competitive mode has been enabled.

Battery Life

VAXEE states a maximum battery life of 110 hours when using the default run mode and 38 hours when using competitive mode, at a polling rate of 1000 Hz for each. Both 2000 and 4000 Hz already default to competitive mode, and 34 and 30 hours are cited for these, respectively. As the E1 Wireless lacks software, one could assume that checking the battery charge status is impossible, but that is not the case. Instead, by pressing the right and middle buttons, the current charge status will be displayed through the LED at the front, with a green light signifying 100-61% charge, blue light 60-21%, red light 20-10%, and blinking red light a charge of less than 10%. Of course, this isn't granular enough to precisely gauge anything, but at least gives one an idea of when charging may be needed. For the record, after seven hours of continuous and mixed use at 4000 Hz and 1000 Hz in competitive mode, I only ever got to see the first charge stage.

Using the included USB Type-A to Type-C charging cable, I also measured the charging speed during the constant current stage. When lifted, 0.325 A can be measured, which drops to 0.315 A when not lifted. The battery has a capacity of 400 mAh (3.7 V) and utilizes a 3-pin JST connector.
