Razer Blade 18 400W AC Adapter

This 20V 400W power adapter is built for the Razer Blade 18 lineup. It supplies the high wattage needed to run the laptop and charge the battery at the same time. The unit accepts a wide 100 V to 240 V input range for worldwide use. It is a direct replacement for the original charger that shipped with the notebook.

Sustained 400W delivery for gaming loads

The adapter maintains its full 400 watt output during extended gaming or rendering sessions rather than throttling after a short burst. Continuous power keeps CPU and GPU clocks stable when the system draws maximum current. The 20 volt rail matches the Blade 18 power profile exactly. Reliable output prevents unexpected shutdowns under heavy load.

Slim design with rubberised cord and cable wrap

The compact brick weighs 0.98 kg and slides easily into a laptop bag for travel. A rubberised power cord resists kinks and abrasion from daily packing. An integrated cable wrap keeps the lead tidy when stored. The barrel connector seats firmly in the Blade 18 charging port for a secure connection.

Questions about this item

How loud or hot does the 20 V 400 W adapter get when it runs all day?

The brick has a slim form factor and a rubberized cord with a built-in cable wrap, designed to stay cool and quiet during extended sessions.

What must I already own for this adapter to work with my laptop?

It is made for the Razer Blade 18 model RZ09-0529 and accepts 100 V to 240 V mains input, so you need that laptop and a standard wall outlet.

Will the 20 V output charge my older Blade 18 that came with a lower-wattage brick?

The adapter delivers 20 V at 400 W for the RZ09-0529; using it on other Blade 18 units is not confirmed by the manufacturer.
