2-power 2P-45N0294 - fonte de alimentação para portátil - interior - 100 - 240 V - 45 W - 20 V - proteção contra sobrecorrente - proteção contra sobretensão - proteção contra curto-circuito

When a laptop's original power brick fails, many users settle for generic replacements that run hot, deliver unstable voltage, or lack essential safety circuits. The 2-POWER 2P-45N0294 takes a different path: a purpose-built 45-watt AC adapter engineered for dependable indoor charging with overcurrent, overvoltage, and short-circuit protection. Its 20-volt output and 2.25-amp current rating match a wide range of notebooks that require a compact, efficient power source, while the universal 100–240 V input makes it suitable for use in homes, offices, or travel destinations worldwide (plug adapter may be needed). The black housing resists scuffs and blends discreetly into any workspace, and the fixed cable design eliminates the need for separate cords. Whether replacing a lost adapter or keeping a spare at a second desk, this unit delivers steady, safe power without the bulk or noise of larger bricks.

Highlights

• 45 W total output with 20 V DC and 2.25 A current for compatible laptops
• Wide input range: AC 100–240 V, 50/60 Hz for global use
• Three-way protection: overcurrent, overvoltage, and short-circuit safeguards
• Indoor-rated design with a durable black enclosure
• Compact and lightweight for easy storage or travel

In daily use

The 2P-45N0294 sits unobtrusively on a desk or floor, its matte black finish resisting fingerprints and minor scratches. The integrated cable keeps the setup tidy, and the adapter runs cool under normal load thanks to efficient power conversion. Because it accepts standard wall voltages from 100 to 240 volts, it can be packed for international trips with only a plug adapter change. Users who need a reliable second power supply for a home office or a replacement for a failed original will appreciate the consistent 20-volt output that prevents charging interruptions and protects sensitive laptop electronics from voltage spikes.
