Vszerda 240W Laptop Charger

This 240W AC adapter delivers 20V at 12A through a 4.5mm by 3.0mm barrel connector. It is built as a direct replacement for the original power supply on compatible MSI gaming laptops. The unit ships with a US power cord and accepts 100V to 240V input for worldwide use.

Thermals and Power Draw

The adapter may become warm during charging, which the manufacturer notes as normal behaviour. No fan is present, so operation is silent. It draws up to 240W from the mains to supply the rated 20V 12A output.

Connector Compatibility

The 4.5mm by 3.0mm barrel tip and 20V 12A output are the single specification that decides fit. Buyers whose laptop requires a different connector size, voltage or current cannot use this adapter.

Questions about this item

How do I install the Vszerda 240W adapter and what step do people often miss?

Plug the US power cord into the adapter brick, then insert the 4.5*3.0mm connector firmly into the laptop until it clicks; the step often missed is verifying the original adapter also reads 20V 12A 240W before swapping.

What maintenance or replacement will this charger need later?

The US power cord and 4.5*3.0mm tip are the only wear items; replace the cord if the plug blades loosen or the cable frays, and replace the tip if the centre pin becomes wobbly.

What limit appears first during sustained high-load use?

The 240W maximum output power is the first ceiling; once the laptop draws the full 12A at 20V the adapter cannot supply more and will throttle or shut down.
