Just got it, all the glory to SBT 90.2 !
My collection so far, and for size comparison….
Onboard charging/discharging feels finicky.
Charging with a 15W USB-A charger (comes with Motorola phone) via a USB-A to USB-C cable - OK
Charging with a 15W USB-C charger (comes with Pixel 4a phone) via a USB-C to USB-C cable - No charging indicator LED.
Charging with an 87W USB-C charger (comes with macbook pro) via a USB-C to USB-C cable - No charging indicator LED.
Charging with a PD3.0 compatible USB-C charger via a USB-C to USB-C cable - OK
Charging speed is OK, with the 15W USB-A charger, current over USB cable measured 2A when the battery is at 3.6V, and 0.5A when the battery is at 4.05V.
Power bank mode is not as convenient as I have imagined because it requires the use of the included USB-C to USB-A Female adaptor.
Say my phone has an USB-C port, I cannot charge it by connecting them via an USB-C to USB-C cable.
Instead, I need to use the adaptor plus an USB-A to USB-C cable.
I don’t have a lux meter, so I pointed it to the ceiling and took video with manual exposure settings.
Turbo mode lasted 50 seconds, then stepped down over a period of 60 seconds to reach steady state.
The center pixel’s RGB values are (209,207,205) at max brightness and (82,82,77) at steady state, no idea how this converts to candela or lumen.
but too floody for practical use, light reflected from the ground and near objects is blindingly strong.
