DC Output Voltage and Maximum Current
The maximum available DC output current depends on the selected voltage.
| Selected DC Voltage |
Maximum Output Current |
| 15V DC | 6.0A |
| 16V DC | 6.0A |
| 18V DC | 5.5A |
| 18.5V DC | 5.4A |
| 19V DC | 5.3A |
| 19.5V DC | 5.2A |
| 20V DC | 5.0A |
| 22V DC | 4.5A |
| 24V DC | 4.1A |
These are the published maximum current ratings for each voltage setting. Actual output current depends on the connected device's requirements.
For example, a laptop requiring 19V at 3.42A draws approximately 65W. The adapter's 19V setting is rated for up to 5.3A, making its published current capacity sufficient for that example, provided the connector, polarity, and other compatibility requirements are also met.
Important:
Always select the voltage specified by the connected device. Choosing an incorrect voltage can damage the equipment. The adapter does not automatically detect the correct laptop voltage.
Interchangeable Laptop DC Connector Tips
The NBAC90U includes eight interchangeable power tips designed to accommodate different DC input connector sizes used by laptop computers and other electronic devices.
The original compatibility information identifies the following connector tip families and example manufacturers:
| Tip |
Example Compatible Brands |
| Tip A | Sony, Samsung, Fujitsu |
| Tip B | IBM, Lenovo, Lite-On |
| Tip C | Sharp |
| Tip D | NEC, Toshiba |
| Tip E | Acer, ASUS, Compaq, HP, LS, NEC |
| Tip F | Acer, ASUS, Lite-On, Toshiba |
| Tip G | Samsung |
| Tip H | Dell, Lite-On |
| Tip L | Acer, ASUS, BenQ, Dell, IBM, Compaq, Delta, Fujitsu, HP, Gateway, Lenovo, Lite-On, LS, NEC |
Note: The original compatibility chart lists nine tip designations, while the package contents specify eight included tips. The table above is a reference to the published tip families and does not confirm that every listed tip is included.
Compatibility depends on the specific laptop model, connector dimensions, electrical requirements, and power adapter identification system. Some laptops may reject or limit operation with universal adapters even when the connector fits.
How to Use the NBAC90U Universal Power Adapter
Step 1 — Select the Correct DC Output Voltage
Check the original AC power adapter label or the DC input specifications of your laptop or electronic device.
Identify the required input voltage, such as 19V DC, 19.5V DC, or 20V DC.
Use the voltage selection switch on the NBAC90U to set the required voltage before connecting the adapter to the device.
The available settings are 15V, 16V, 18V, 18.5V, 19V, 19.5V, 20V, 22V, and 24V DC.
Voltage Selection Warning:
Never change the voltage setting while the adapter is connected to a powered device. Disconnect power and verify the selected voltage before reconnecting.
Step 2 — Choose the Correct Connector Tip
Select a connector tip that matches your device's DC power input jack.
Before attaching the tip to the adapter cable, carefully check its physical fit in the device's power jack.
The connector should fit securely without excessive force or looseness.
Also verify that the tip provides the correct polarity and electrical connection required by the device.
Step 3 — Attach the Connector Tip
After identifying the correct connector, attach it securely to the DC output cable of the power adapter.
Some devices may accept the adapter's existing connector without an additional tip, depending on the connector configuration.
Step 4 — Connect AC Power
Connect the included USA AC power cord to the adapter, then plug it into a suitable AC wall outlet.
The adapter accepts 100–240V AC input, making it suitable for many international power systems when used with an appropriate compatible AC power cord.
Step 5 — Connect Your Device
After confirming the correct output voltage, connector fit, polarity, and power rating, connect the adapter's DC output plug to the device.
Verify that the equipment powers on and operates normally.
