Review on 💡 KINGDO Yoga Power Supply Charger 65W 20V 3.25A or 5.2V 2A for Lenovo Yoga 900, Yoga 700, Yoga 3 Pro, Yoga 4 Pro - 6.7Ft Power Cord + Carrying Pouch by Luz Rojas

I use this as a supplemental source of nutrition - and only occasionally. For that it works great. I don't think it's as good as the Lenovo OEM PSU as it gets very hot. I did a test with an OEM power supply and then with this one. For the test, I let the battery run down and then plugged in the power supply. During testing, I left the machine on and busy, consuming a lot of power. I measured the temperature with an instant infrared thermometer pointed near the USB port (which seemed to be the hottest spot). I also measured the power with Kill A Watt. Both showed a peak power of 68-70 watts. After 30 minutes, the OEM PSU peaked at 145 degrees, but the Kingdo continued to heat up to 193,193 degrees and felt quite hot. Although there was no smell of burning.
