I've been charging my chromebook via USB-C from my Jackery (15W draw @5V) while simultaneously charging with a 60W solar panel. Most of the time the input (10-40W) exceeds the output and averages about 30W over 6-7 hrs.
Does this cycle the battery, albeit slowly, and decrease the battery longevity?
My limited understanding says the 12V-18V DC input is being buck/boosted to ~14.5V. From there, current will either flow to the battery or get bucked down to 12V for the DC output or 5V for the USB-C. When the draw from either of these exceeds the solar input, it obviously draws from the battery then. Please excuse my layman's knowledge of circuits.
So is this going to reduce the cycle capacity on the Jackery? Mine is "only" rated for 500 cycles and I'm just using the Jackery as a "buffer" because I don't have another battery or charge controller to experiment with.
I mostly want to understand how to use my batteries the least amount possible when energy from the panel is available.
I did search the forum and found a discussion about the Bluetti and EcoFlow but I was wondering if Jackerys work differently.
