Buyers who need a different connector size or a lower wattage unit should look elsewhere. This adapter is not for laptops that require a proprietary charging interface other than the 4.5*3.0mm barrel plug.

Questions about this item

Will the 4.5×3.0 mm connector or the US power cord wear out first?

The 4.5×3.0 mm DC connector sees daily plug cycles and is the part most likely to need replacement before the fixed US power cord.

What limits continuous 240 W output during long gaming sessions?

The adapter delivers a fixed 20 V at 12 A; sustained loads that demand the full 240 W will hit that current ceiling first.

How hot does the brick get when it runs all day at 240 W?

The supplier notes the adapter may get a little hot during charging and calls this normal.
