ROLADA Universal Laptop AC Adapter 90W with 15 Tips

ROLADA's universal AC adapter delivers switchable 90W/75W/70W/65W/45W outputs and 15 interchangeable tips to power a wide range of laptops and Chromebooks without using USB-C.

This compact power brick is designed as a single, travel-ready replacement to cover many common notebook brands including HP, Dell, Lenovo, Asus, Acer, Samsung, Toshiba, Fujitsu, Sony and Gateway. It accepts 100–240V input for worldwide use, offers four common voltage settings (18.5V, 19V, 19.5V, 20V) and ships with a set of connectors so you can match the tip to your model. It is not a USB-C charger and it does not include an M1 connector — check your laptop’s barrel size before purchase.

Which laptops will this ROLADA adapter work with?

This adapter supports dozens of notebook and Chromebook series from major manufacturers by providing multiple voltage and wattage options plus 15 tip types. It covers many ThinkPad and IdeaPad models, a wide range of Dell Inspiron/XPS lines, HP Envy and Pavilion series, Acer Aspire and Chromebook families, as well as select Asus, Samsung, Sony and Toshiba models.

• Voltages: 18.5V, 19V, 19.5V, 20V — match with your laptop’s required volts.
• Wattages: selectable up to 90W (also 75W/70W/65W/45W) for compatibility with smaller and mid-range notebooks.
• Includes 15 connector types — find the barrel size used by your laptop model.

How do I choose the correct connector and power setting?

Select the connector that fits your laptop’s DC jack snugly and pick the voltage that matches the original adapter label. Using the correct tip and voltage prevents charging problems; the adapter’s wattage should meet or exceed your laptop’s power draw for reliable operation.

• Find your laptop’s required voltage and amperage on its original adapter or underside label.
• Choose the ROLADA tip that seats firmly and supplies the correct polarity and size.
• If your laptop needs more watts than one of the listed settings, use a higher-rated setting (up to 90W) while matching voltage.
• Do not use this product for devices that require USB-C power delivery or M1-specific plugs.

What safety and compatibility features are included?

The adapter includes protections commonly expected in modern AC adapters: surge protection, over-voltage and short-circuit safeguards, and an input range for safe multi-country use. It’s intended as a general replacement but always verify mechanical fit and voltage before connecting.

• Input: 100–240V 50–60Hz — suitable for travel with the appropriate plug adapter.
• Built-in protection circuits for basic electrical safety during normal use.
• 15 tips to reduce the chance of mechanical mismatch across many laptop models.
• Not compatible with USB-C port/PD charging or M1 exclusive connectors — confirm your model’s jack type.

Who is this for? If you need a single, versatile replacement charger to power multiple notebooks or to keep as a travel spare, ROLADA’s universal adapter is a practical choice. It’s aimed at students, IT technicians, small offices, and frequent travelers who want fewer adapters and the flexibility to serve various brands. Do verify your laptop’s voltage and barrel type before buying; this adapter is ideal when your device uses a barrel connector and requires 18.5–20V at up to 90W.
