Review on 💻 aceyoon Laptop Power Adapter Kit: 38 PCS Universal Tips Connector for Lenovo Thinkpad Power Supply - 5.5mm x 2.1mm DC AC Plug Jack Set by Emma Santos

I love this set! I included two different HP mini laptops. These tips will work if you have a 5.5mm cased power adapter since your laptop runs at 18.5 to 19 volts. Most 5.5mm blocks run at 19V and 90W or less, but be sure to check your laptop's specs! These spikes do not change the voltage of the power blocks. My adapter is 90 watts, 19 volts, 4.5 amps, which will work with most laptops shown here BUT the last unit will have a voltage switching feature. and they are there :)
