When an HP tablet stops powering on, loses power during use, or becomes unreliable because its adapter is worn or damaged, replacing the power supply can restore normal operation without replacing the device. The HP WAE009 794797-004 is an 18W AC power adapter rated at 12V and 1.5A, designed for compatible HP tablet systems including the HP Pro Tablet 10 EE G1 and selected HP Omni 10 models.

This replacement adapter is intended for users who need a properly matched power source for an older HP tablet rather than a generic 12V adapter with an uncertain connector. Before ordering, compare the model number, output rating, connector dimensions, and polarity of your existing adapter with the specifications below.

Technical Specifications

OEM Replacement Compatibility

This adapter is associated with the following HP power-supply references:

• HP WAE009
• HP 794797-004

Important: 795552-001 appears in some catalogs as an 18W WAE009-family adapter with a different connector configuration. Match the physical connector and electrical specifications before using it as an interchangeable part reference.

Compatible Devices

• HP Pro Tablet 10 EE G1
• Selected HP Omni 10 models may use related 12V 1.5A adapters; verify the original adapter and connector before ordering.

Compatibility should be confirmed by comparing the device model, adapter output rating, connector dimensions, and polarity. A matching 12V rating alone does not guarantee compatibility.

Replacement & Troubleshooting

A failing AC adapter can cause symptoms that look like a tablet hardware problem. Common signs include no power, intermittent shutdowns, loss of charging during use, or power that cuts in and out when the adapter cable is moved.

Before replacing the tablet itself, inspect the adapter for cable damage, unusual heat, loose connections, or visible wear. If the existing power supply no longer provides stable output, a correctly matched 12V 1.5A replacement can help restore normal operation.

Do not substitute a generic adapter solely because it has a 12V output. The connector size, polarity, and required current rating must also match the original specification.

FAQ

Can this replace an HP WAE009 794797-004 adapter?
Yes. This listing is specifically based on the HP WAE009 / 794797-004 18W power specification. Confirm the connector and polarity before ordering.

What devices is the WAE009 used with?
The WAE009 12V 1.5A adapter is associated with HP tablet products including the Pro Tablet 10 EE G1 and selected Omni 10 5600-series models.

Is 12V 1.5A enough for a compatible HP tablet?
Yes, where the device is specified for a 12V 1.5A, 18W supply. The replacement should meet or exceed the original current requirement while matching the voltage and connector.

Can I use another 12V adapter with the same wattage?
Only when the connector dimensions, polarity, voltage, and current requirements are also correct. The same wattage by itself does not establish compatibility.

What should I check before ordering?
Compare your original adapter's model or part number, 12V 1.5A output, connector dimensions, polarity, and the exact HP device model. This is the safest way to avoid an incorrect replacement.

The HP WAE009 794797-004 is an 18W AC power adapter providing 12V DC at 1.5A for compatible HP tablet devices, including the HP Pro Tablet 10 EE G1 and selected HP Omni 10 models. It is intended as a replacement for the corresponding WAE009 power adapter when the original unit is damaged, missing, or no longer providing stable power.
