2-Power-virtalähde AC 2.31A sisältää virtajohdon, korvaa TPN-LA15

When a laptop charger fails, downtime is measured in missed deadlines and lost productivity. The 2-POWER ALT283370B is a direct replacement for the HP TPN-LA15 adapter, delivering the same 19.5V / 2.31A output with a 4.5x3.0mm blue tip connector. Unlike generic universal chargers that rely on interchangeable tips and often compromise on stability, this unit is built specifically for the target notebook series, ensuring a secure fit and consistent power delivery. The included AC power cable means you can unpack and start charging immediately, without hunting for a compatible cord.

Highlights

• Exact electrical match: 19.5V DC, 2.31A, 45W output
• HP Smart Pin connector (4.5mm x 3.0mm, blue tip) for reliable contact
• IEC C6 cloverleaf AC input with region-specific power cable included
• Comprehensive protection: over-voltage, over-current, short-circuit, over-temperature
• Energy Star compliant efficiency to reduce wasted power and heat
• Durable ABS housing with a 1.5m DC cable for flexible placement

In daily use

The adapter operates on any AC mains from 100 to 240V at 50/60Hz, so it works in offices, homes, and international travel with the appropriate plug. The 1.5-metre DC cable gives you room to reach a wall socket without straining the connector, while the black finish and compact design keep your workspace tidy. Built-in safeguards protect both the adapter and your laptop from power fluctuations, and the Energy Star rating means it draws only what is needed, staying cool even during extended charging sessions.
