NeaHao 130W 19.5V Charger for Dell Inspiron & AIO

A NeaHao replacement power adapter that delivers up to 130W (19.5V, 6.67A) for compatible Dell Inspiron laptops and all-in-one desktops, with backward compatibility to lower-wattage Dell models.

This NeaHao power supply is engineered as a direct, high-capacity replacement for a broad range of Dell Inspiron laptops and All-in-One desktops. It accepts 100–240V AC input and supplies stable 19.5V DC output at up to 6.67A, and will safely power systems that normally use 130W, 90W, 65W, or 45W Dell adapters. The package includes the 130W adapter and an AC power cord, and the adapter uses a 4.5mm × 3.0mm barrel connector to match the laptop port pictured in product references.

How does the power and compatibility behave with lower-wattage systems?

The NeaHao adapter provides up to 130W at 19.5V and will safely supply devices that normally require 90W, 65W, or 45W, as long as the device accepts the same voltage and connector. Devices will draw only the current they need, so the higher wattage adapter does not force extra power into a lower-demand system.

• Output: 19.5V, 6.67A maximum (130W).
• Backward compatible with 19.5V 4.62A (90W), 3.34A (65W), 2.31A (45W) models.
• Universal AC input range: 100–240V for worldwide use with proper plug.

What are the physical details and connector specifics?

The adapter uses a cylindrical barrel plug sized 4.5mm outer by 3.0mm inner to match the Dell power jack used on many Inspiron and AIO systems. The housing includes standard ventilation and strain-relief points for the cord to reduce wear during daily use.

• Connector size: 4.5 mm × 3.0 mm barrel plug (refer to product image for scale).
• Includes one 130W NeaHao power adapter and one AC power cord in the box.
• Built to fit OEM dimensions and mount points for a neat, stable connection.

What warranty and safety features are included?

NeaHao provides a 12-month limited warranty to cover manufacturing defects, plus built-in protection circuitry inside the adapter to guard against over-current, over-voltage, and short circuits. The adapter is designed for reliable daily use and to meet common safety expectations for laptop power supplies.

• 12 months warranty from the date of purchase.
• Internal protections for short-circuit, over-current, and over-voltage events.

Who is this for: If you own a Dell Inspiron laptop or a Dell All-in-One desktop in the listed model families and need a dependable replacement or spare charger, this NeaHao 130W adapter offers a high-capacity, plug-compatible solution. It's ideal for users who want one adapter that can also power lower-wattage Dell machines, travelers needing worldwide input compatibility, and anyone replacing a lost or damaged Dell-branded adapter without wanting to pay OEM prices. Ensure your system uses a 19.5V input and the 4.5×3.0mm barrel connector before purchasing.
