    Portable Work Light

    Posted by RCpilot on Feb 12th 2024

    I originally purchased it for it’s dual lighting capability (i.e. flashlight + floodlight). Both modes function very well, they provide good illumination and battery life is excellent. Battery charge level is indicated with multiple green LED lights and it’s charge won’t diminish while sitting idle in a drawer or glove box. It felt good to hold in my hand and will lay flat or stand on end when you put it down. However, I was also able to use it as a portable power supply. My Renogy One Core requires DC current to operate. In order to install it, I had to place it in an area with the best signal reception, and so the portable power feature was an unexpected benefit I am sure I will use again. All-in-all it is a great product with a reasonable price tag. I am sure I will be ordering more of them.
