What this charger does

The myVolts 90W universal adapter supplies 15-20V at up to 4.5A for most mainstream notebooks and adds a 5V 2.1A USB port for phones or tablets. Fifteen interchangeable tips cover HP, Dell, Lenovo, Asus, Acer, Sony, Fujitsu, Toshiba, Gateway, JBL, IBM and Samsung models. It is aimed at owners who need one compact brick for several laptops or a spare that matches the original voltage range.

Fitting the right tip

Select the tip marked for your brand and model, push it firmly onto the DC cable until it clicks, then plug the 2.5M AC cord into the wall. The unit auto-senses the required voltage between 15V and 20V so no manual switch is needed. The most common issue is choosing a tip that looks similar but has a different inner diameter or pin layout; always verify the printed code (for example M21 for HP 4.5 x 3.0mm with pin) against the laptop’s own label before ordering.

Behaviour during long sessions

At full 90W load the adapter runs warm but stays within its thermal limits thanks to high-efficiency circuitry and multiple protection circuits. Output voltage remains stable across the 15-20V range even when the battery is deeply discharged and the CPU sustains high clocks. It is not suited for gaming laptops or workstations that draw more than 90W continuously; those machines will throttle or drain the battery while plugged in.

Questions about this item

How can I confirm the charger is delivering the correct 15V-20V output after plugging it in?
