2-power 2P-5A10H42921 - laptopvoeding - binnen - 100 - 240 V - 45 W - 19 V - 2,37 A

When a laptop's original power brick fails, the search for a replacement often leads to generic, poorly regulated adapters that can compromise battery health or even damage the device. The 2-POWER 2P-5A10H42921 stands apart by delivering exactly the voltage and amperage your machine expects: 19V at 2.37A, for a stable 45W output. Built for indoor use with a universal 100–240V input, it works across different mains voltages without a separate transformer. Over-voltage, over-current, and short-circuit protection are integrated, so the adapter shuts down safely in fault conditions instead of passing harmful spikes to the laptop.

Highlights

• Exact 45W output: 19V DC, 2.37A – matches the original specification for many Lenovo and other laptops
• Wide input range: 100–240V AC, 50/60Hz – safe for use in virtually any country
• Indoor-rated design: intended for desk, office, or home use, not outdoor or wet environments
• Built-in protection: over-voltage, over-current, and short-circuit safeguards protect both adapter and laptop
• Compact and reliable: replacement-grade component with consistent power delivery

In daily use

Plug the adapter into a standard wall outlet and connect the DC output to the laptop. The adapter automatically negotiates the correct voltage and current, so there is no need for manual switches or settings. Because it accepts 100–240V, travellers can use it with a simple plug adapter. The casing is designed to dissipate heat efficiently during continuous operation, and the protection circuits ensure that a faulty laptop or a shorted cable will not cause a fire or damage the adapter itself.
