  • 19 V 2.37 A rating matches original charger specifications

45W 19V AC adapter for Asus laptops

This myVolts adapter delivers 19V at 2.37A for a maximum of 45W, with a 5.5x2.5mm barrel connector. It suits owners of listed Asus X551, X555, X751, X451, X505, X756 and X705 models who need a replacement charger.

110-240V input range and fixed 19V output

The unit accepts AC input from 110V to 240V, making it usable on mains supplies worldwide without a voltage selector. Output is fixed at 19V; it cannot charge devices that require a different voltage or a USB-C Power Delivery handshake.

Replaces lost or faulty 33W-45W Asus chargers

It substitutes original Asus adapters rated 33W (19V 1.75A) or 45W (19V 2.37A) with the same 5.5x2.5mm tip. The jump is worth it when the original brick is damaged, missing, or when a spare is needed for travel; it does not add power for laptops that demand more than 45W.

Questions about this item

Should I pick the 45 W or the 33 W output rating for my Asus laptop?

Both ratings share the same 19 V connector; the 45 W (19 V 2.37 A) version covers the original ADP-45BW requirement, while the 33 W (19 V 1.75 A) rating is also listed as compatible for the same models.

What does the 19 V 2.37 A output actually deliver inside my X551 or X751?

It supplies up to 45 W at 19 V, matching the factory ADP-45BW spec so the laptop charges at full speed while running normal workloads.

Is the 5.5 × 2.5 mm barrel tip the only fit for these Asus models?

Yes — the connector is a 5.5 mm outer by 2.5 mm inner barrel, and the supplier highlights that confirming this exact tip size is mandatory for every listed model.
