Yeah like "flashlight is pretty bright but the switch quit after 2 months" and if I see several reviews talling about failed switches I kmow what's up. A good product will have a 1 star review talking about "flashlight tastes terrible and hurt my teeth."
Could be any number of things from the charger not being USB-C PD to the sun overheating your phone and causing the safeties to stop or slow down the charging. I haven't actually found a car charger with a buckboost converter in it to provide higher voltages even when the circuit board is available online for hobby projects.
"SENT ME TO ER, and denied return. I don't know why guys enjoy flashlights so much for "playtime", but this one ain't it, had to go to er when gf got a little too rough with it."
Even 2 reviews is kinda sketchy, because it means the listing for that memory foam keyboard wrist rest is either scrubbed of negative reviews, or it's only been up for a few days because it's a shit product that has been sold under 804 different brand names in the past four years; they just switch up the branding every time someone gets the message through that the wrist rest is made out of leaded asbestos and it makes your lungs antisocial which is just another way of scrubbing negative reviews.
