  • Watts in a resistive example like yours is Volts x Amps. I would have been able to much better answer this question a year ago so forgive me if I’m misremembering the specs but I’ll answer since nobody else has. Two things that suggest to me this might be a bad idea:

    • Charger is 40W, that’s probably usb PD (I don’t know anything about QC so maybe I’m wrong). PD supplies more than 15W (5V x 3A) by stepping up the voltage, not the amperage. While stepping up either would likely be bad or very bad for some part of your circuit, don’t worry about that though; without the powered device telling it to, PD won’t activate. It should max out at 15W… I think. It depends on the resistance on the CC lines and using a splitter could screw up the resistance that tells the power supply which USB version to support so it can go up to 3A (15W). Sorry, it’s been a while since I’ve worked with USB power. 2 strips of 11W will need more power than that. Basically my concern is you won’t get adequate power out of the charger for one reason or another.
    • Where are you getting the 11.52W/min number? Watts don’t have a time unit and that much precision sketches me out. Almost as if someone who isn’t adequately educated measured the power straight off a multimeter once and just wrote that on a product page. Is the LED strip from a reputable manufacturer?







  • I’ll tack on to what the other commenter said:

    • Cost: I considered myself a heavy searcher (software engineer and gamer) and have been surprised to see I have rarely exceeded even half of my allotted searches ($5/mo, 300 searches). I’m now reprogramming my brain to stop turning to alternatives when something should be easy to find because “I might use up all my queries”.
    • Better: apart from all of the cool features, and there are many, there’s also that it just “feels better”. I don’t know how to qualify that despite being a professional in that world. It’s kinda the opposite feeling that I had using Google over the last 5+ years where I wondered if I was getting dumber or if the internet (and Google) was absolutely full of garbage.

    It’s on the very short list of subscriptions I pay for right now despite having a very limited budget at the moment.
