ABLEGRID 20V Charger for Advent Roma Laptops

This 20V 3.25A AC adapter replaces the original power supply for Advent Roma 1001, 2001, 3001 and 4001 models. It delivers DC output through a barrel tip connector and includes a detachable AC power cable. The unit is a non-OEM replacement built to match the original specifications.

Worldwide AC Input with Fixed Output

The charger accepts AC 100-240V at 50-60Hz for global mains compatibility. Output voltage is fixed at 20V DC with a maximum current of 3.25A. Polarity and tip dimensions must match the laptop's DC jack exactly; the adapter cannot adjust voltage or current for other devices.

Simple Swap with Fit Verification Required

Installation consists of connecting the barrel tip to the laptop and plugging the IEC cable into a wall socket. The most common issue is ordering a tip size that does not fit the Roma charging port. Buyers must confirm the connector dimensions before purchase to avoid a non-functional unit.

Questions about this item

Should I pick this 20V 3.25A charger for my Advent Roma 3001 or is there another version?

This single model is rated 20V 3.25A and lists compatibility with Advent Roma 1001, 2001, 3001 and 4001, so it covers all four models.

What does the 20V 3.25A rating mean when the adapter is plugged into my laptop?

It supplies 20 volts at up to 3.25 amps DC, giving the laptop the exact voltage and current the original power brick provided for charging and operation.

The barrel tip is mentioned — what interface does it use and what does that limit?

It uses a barrel-tip DC connector sized for the Advent Roma series; the tip geometry and 20V 3.25A output cap the power delivery to that specific laptop range.
