Review on ⚡ OOYCYOO MPPT Charge Controller K100A - 100 Amp Solar Panel Charge Regulator with LCD Display for 12V/24V Auto Battery Systems by Nick Granner

Mine worked 3 weeks and died. The seller did not respond to the replacement of the goods. From that moment on, I learned to pay attention to seller ratings and not just reviews. Check seller ratings before you buy cheap crap. I bought because of the price and now I need a new charge controller because there is no guarantee. Better to spend twice as much for a better device. Today I'm going to buy one of three different blocks to replace this one. I will call everyone first to find out how the guarantee works and if there is anyone alive. I will also check the seller ratings. If you buy this crap after reading this review, I sincerely hope you get better results. If you're offline I recommend buying two so you have an in-place backup. Then start saving to buy another spare part in case the second one fails.
