Zell 135W AC adapter 19.5V 7.4mm tip

This new Zell Electronics adapter delivers 135 watts at 19.5 volts and 7.1 amps through a 7.4 mm outer-diameter barrel connector. It accepts 100-240V input at 50-60Hz and includes a three-prong AC inlet. The unit carries CE, FCC and RoHS certification with over-voltage, short-circuit and over-current protection.

Suits HP Elite DC 7800-8300 TouchSmart 600-620

The charger matches the listed HP and Compaq part numbers for Elite 7800, 7900, 8000, 8100, 8200 and 8300 desktops plus TouchSmart 600, 610 and 620 all-in-one models. It also covers the NC and NX notebook series shown in the compatibility data. Buyers needing a different voltage, wattage or tip diameter should look elsewhere.

Critical spec: 7.4 mm outer / 5.0 mm inner tip

The connector’s 7.4 mm outer and 5.0 mm inner diameters are the single detail that decides fit. Verify this exact tip size against the original adapter or the device’s service manual before ordering. An incorrect barrel dimension will prevent a secure connection even when voltage and power ratings match.

Questions about this item

Will this 19.5V 7.1A adapter run my HP Elite 8300 without stressing the original power circuitry?

The adapter matches the 19.5V 7.1A 135W specification used by the Elite 8300 series, so it delivers the same voltage and current the desktop expects.

How do I confirm the 7.4mm tip is seated correctly and the unit is delivering 135W after I plug it in?

The connector clicks into the 7.4mm jack; the desktop powers on normally and shows no battery or throttle warnings under load.

Does the box include a three-prong mains lead or must I source one separately?

The adapter has a built-in three-prong inlet; a standard IEC C13 mains cable is required and is not included.
