Review on 130W 19.5V 6.7A Power Adapter Charger for Dell Inspiron 15 7559 N5110 N7110 Precision M20 M60 M70 M90 M2400 Vostro 500 1000 XPS M1210 M1330 Studio 1535 1536 PA-4E Power Supply Cord by Toki Louton

Not sure what warmth and transparency have to do with this device. If you mean purity of appearance or invisibility, then it isn't. It's actually a pretty big rock. This is for a gaming laptop though, so the refills are obviously larger. Volts and amps are as specified. I also checked the correct output characteristics with an electrical multimeter. Runs the laptop at full load/maximum power for an hour with no issues. It's been good ever since.
