Replacement charger for STONE and Advent laptops

This ABLEGRID AC adapter delivers 20 V at 3.25 A and accepts worldwide input from 100 to 240 V at 50 to 60 Hz. It is built as a non-OEM unit with CE, FCC and RoHS certifications and includes over-voltage and over-heat protection. The barrel tip matches the original connector for direct compatibility. A new power cable is supplied in the package.

Fits STONE MR055 and Advent 7109 7113 8111 8115 8117

The adapter plugs into any standard mains socket and supplies the DC output those models require. No additional converters or proprietary docks are needed, freeing a desk outlet that a bulkier brick might occupy. Verify the barrel tip dimensions before connecting to ensure a secure fit. The unit is designed for continuous indoor use with adequate ventilation.

Suits owners replacing a lost

Buyers who need a higher wattage unit or a different voltage should look elsewhere. Users requiring USB-C Power Delivery or multiple output tips will not find those features here. The product is a single-output barrel-tip adapter only. Anyone unsure of their laptop's exact DC rating should confirm the specification before ordering.

Questions about this item

How long can the 20V 3.25A adapter run before over-heat protection engages?

The charger includes over-heat protection that will shut it down if temperatures exceed safe limits during sustained use. Keeping the unit in a well-ventilated area and avoiding placement on insulating surfaces helps it run continuously.

How much fan noise or heat does the 20V 3.25A charger produce when powering a laptop all day?

The adapter has no fan, so it operates silently. It will become warm under continuous load, which is normal for a sealed power supply; ensure airflow around the case to keep temperatures in check.

Which laptop models must I already own for this 20V 3.25A barrel-tip charger to work?

It is listed as compatible with Stone MR055 and Advent 7113, 7109, 8117, 8111 and 8115 laptops. Verify that your device requires 20 V DC at 3.25 A and uses the same barrel connector before purchasing.
