2-power 2P-450-18920 - Fonte de alimentação para portátil - Interior - 100 - 240 V - 45 W - 19,5 V - Proteção contra sobrecorrente - Proteção contra sobretensão - Proteção contra curto-circuito

Unlike generic universal adapters that compromise on safety or compatibility, the 2-POWER 2P-450-18920 is built around a fixed 19.5V output and a 45W power budget, making it a dependable choice for laptops that demand stable voltage without the guesswork of adjustable tips. Its triple protection circuitry guards against overcurrent, overvoltage, and short circuits, so your device stays safe even during power fluctuations. The adapter operates on a wide 100–240V input, so it works with mains power in most regions without a separate voltage converter.

Highlights

• Fixed 19.5V / 45W output for consistent laptop charging
• Overcurrent, overvoltage, and short circuit protection
• Wide 100–240V AC input for international use
• Designed for indoor use with standard AC power
• Compact and reliable replacement or spare adapter

In daily use

Plug the adapter into any standard indoor AC outlet between 100 and 240 volts, and it will deliver a steady 19.5V at up to 2.31A. The protection features work silently in the background, cutting power if the current or voltage exceeds safe limits or if a short circuit is detected. This makes it suitable for both home offices and travel, as long as you have the correct DC connector for your laptop. The adapter itself is designed for continuous indoor operation and does not require any configuration.
