Syfrufo 65W 19V 3.42A AC Adapter for HP Monitors

Syfrufo 65W 19V 3.42A AC adapter is a grounded replacement power supply designed to safely run select HP Pavilion and VH/CW/ER series desktop monitors, including the VH240A.

This replacement adapter delivers a fixed 19V/3.42A output and accepts 100–240V input for worldwide use, providing a stable feed for compatible HP desktop displays. It is built as a two-piece set — a converter brick with a permanently attached DC lead and a detachable 3-prong AC mains cord — and includes standard safety approvals stamped on the housing.

How do I confirm this adapter fits my monitor?

Verify both the electrical rating and the physical connector before purchasing. This unit outputs 19V at 3.42A, and the DC plug is a hollow round barrel with a 5.5mm outer diameter and 2.5mm inner diameter with a yellow tip. Do not buy if your display uses a center-pin connector or colored-tip variants like blue or black.

• Check your monitor’s original adapter label for 19V and compatible amperage.
• Measure connector: 5.5mm OD / 2.5mm ID, hollow center, yellow tip.
• Confirm model family: supported HP Pavilion, VH, CW, ER series (e.g., VH240A).
• Avoid if your monitor is in HP’s M-series or X-series families.

Will this adapter work worldwide and with lower-power displays?

Yes — the adapter accepts a universal 100–240V AC input at 50–60Hz so it can be used in many countries with the appropriate plug or travel adapter. It is rated at 65W (19V/3.42A) and can safely supply displays that require lower current, such as 19V/2.1A or 40W screens.

• Universal input: 100–240V ~50–60Hz, 1.8A.
• Fixed output: 19V DC, 3.42A, 65W maximum.
• Backwards-powering: will provide correct voltage for lower-amp monitors.
• Not suitable for devices requiring a center pin or non-whole barrel tips.

What safety and physical features does the Syfrufo adapter include?

The adapter includes a grounded North American Type B 3-prong removable power cord and a converter brick marked with FCC, CE, and RoHS approvals. Expect the brick to become warm during use; that is normal — keep it ventilated and away from soft surfaces to dissipate heat.

• 3-prong grounded AC plug for safe desktop grounding.
• Housing stamped with FCC, CE, RoHS certifications.
• Total cable length ~7.9 feet (2.4 m): 1.2m AC cord + 1.2m DC attached lead.
• Designed for stationary desktop setups with continuous operation.

Which monitors should I not use this adapter with?

Do not use this unit with HP M-series (for example M24f, M27f) or X-series displays, laptops, or any monitor requiring a center-pin connector or a colored-tip plug other than the yellow hollow barrel. Using an incompatible adapter risks damage to the device and voids warranty protections.

• Not compatible with HP M-series or X-series monitors.
• Not for laptops or devices with center-pin power jacks.
• Avoid if the original plug tip is blue, black, or has a center pin.
• Always confirm model and plug dimensions before ordering.

Who is this for: The Syfrufo 65W 19V 3.42A adapter is aimed at users who need a reliable, grounded replacement for select HP Pavilion, VH, CW, and ER series desktop monitors — especially home office workers, students, IT support staff, and businesses maintaining multiple displays. If you need a stable 19V supply for compatible monitors and prefer a detachable grounded cord with recognized safety markings, this kit provides a practical and cost-effective alternative to OEM supplies. Before buying, double-check your monitor model and the DC plug dimensions to ensure a correct match.
