Compatible Dynabook Models

This 65W AC adapter powers and charges Dynabook Tecra and Satellite laptops including the A50, C40, C50 and Z50 series. It replaces original 45W and 65W chargers for the listed part numbers. It is not a substitute for 90W power supplies required by higher-draw configurations.

Input Voltage Range and Connector Limits

The unit accepts AC 100 to 240V at 50 to 60Hz for worldwide mains compatibility. Output is fixed at 19V DC with a current range of 2.1A to 3.42A up to 65W maximum. The barrel connector fits only the models named in the compatibility list; it will not mate with 90W Dynabook ports or other vendor tips.

Power Headroom and Cord Reach

The adapter delivers full 65W output for charging while the laptop runs typical workloads. A combined 12ft cable reach — 6ft AC cord plus 6ft DC lead — gives flexible desk placement without extension leads. Systems that demand more than 65W will not operate correctly from this unit.

Questions about this item

Which of the listed Dynabook models does this 65W adapter replace?

The adapter replaces 45W and 65W chargers for Tecra A50-EC1521, A50-EC1525, A50-EC1528, C40-C1400, C40-C1430, C40-D1400ED, C40-D1410, C40-D1412, C40-D1414, C50-B1500, C50-B1503, C50-D1510, C50-D1512, C50-E1516, Z50-D1552 and Z50-E1522. It does not replace 90W adapters.

What does the 19V 3.42A output mean when the laptop is running a heavy workload?

The adapter can deliver up to 65W continuously at 19V DC, with current scaling between 2.1A and 3.42A depending on load, so sustained CPU or GPU tasks draw the full 65W without voltage sag.

How does the 100–240V 50–60Hz input affect use in different countries?

The wide-range input accepts mains voltages from 100V to 240V at either 50Hz or 60Hz, so the same unit works worldwide with only a local plug adapter for the 2-prong AC cord.
