UGREEN X377 35066 USB-C to HP DC Power Tip
A compact X377 power tip with a USB-C female input and a blue-ring round HP-style centre-pin connector male output for selected HP laptops. It is intended to let a correctly specified USB-C PD charger and cable feed a laptop that uses the matching legacy DC jack.
Product overview
Overview
UGREEN X377 35066 changes the physical laptop-side connector from USB-C female to the blue-ring round HP-style centre-pin connector used by certain HP notebooks. The USB-C receptacle is power input only. It does not carry USB data, video, docking or file-transfer functions.
The exact page lists HP examples requiring 19.5V at approximately 2.31A to 3.33A and describes a 67W power class. A charger’s advertised maximum wattage is not enough by itself: the source must offer a compatible output profile, the cable must carry the needed current, and the laptop must accept the DC connector and electrical characteristics.
The tip contains the model-specific connection path required for its intended use, but it is not a wall power supply and cannot create energy. USB-C PD sources commonly advertise standard profiles such as 20V, while the exact page describes 19.5V laptop use; do not infer the internal method or use an unverified source. If the original adapter label or laptop service documentation cannot be matched confidently, use the manufacturer-approved charger instead.
Verified highlights
Key features
- Exact laptop family: designed for selected HP laptops using the blue-ring round HP-style centre-pin connector.
- USB-C power input: female USB-C receptacle accepts a compatible USB-C PD charger cable.
- Power class: 67W-class use for the exact listed HP requirement.
- Electrical matching: listed HP examples use 19.5V and approximately 2.31A–3.33A; verify the original adapter label.
- Power-only function: no USB data, display signal, network, audio or dock features.
- Compact right-angle body: reduces the number of full charger assemblies carried when the complete PD chain is verified.
- No charger included: the wall charger and USB-C cable are separate and must meet the laptop’s requirement.
- One-brand connector: similar-looking barrel tips can differ in diameter, pin, length and identification behavior.
Know the exact connector roles
USB-C input, DC output and power-chain map
Every link in the chain matters. The tip solves only the final connector interface and must not be used to guess at laptop power requirements.
- Wall outlet: supplies mains power to a separately purchased certified USB-C PD charger.
- USB-C PD charger: must advertise a power profile compatible with the laptop/tip requirement; maximum wattage alone is not proof.
- USB-C cable: must be power-capable for the required current and undamaged; a low-rated or charging-only cable can limit the result.
- USB-C female input: on the X377 tip accepts power from the compatible cable; it is not a laptop data port.
- HP DC male output: round blue-ring plug with a visible centre pin; exact diameter is not stated and must not be guessed.
- Laptop charging circuit: decides whether to accept the source and may report slow/unsupported charging when the chain is mismatched.
- No accessory output: there is no extra USB port and no way to power a second device from the tip.
Where it makes sense
Use scenarios
Use the tip as a travel or replacement connector only after comparing the original power adapter label and physical laptop socket.
- Power a verified compatible HP laptop from one high-quality USB-C PD charger instead of carrying a second full wall adapter.
- Create a compact travel setup with a separately selected PD charger and cable that meet the laptop’s sustained power requirement.
- Keep a compatible tip at a desk or in a service kit for a known laptop model whose original adapter specification has already been documented.
- Use with a multiport PD charger only when that charger maintains the necessary output after other devices are connected.
- Recover temporary charging access when the original adapter is unavailable, provided the laptop jack and electrical requirements are exact matches.
- Not for bench-testing unknown laptops, universal-voltage experimentation or bypassing a damaged/loose laptop DC socket.
A dependable first connection
Setup and usability guidance
Compare first, energise last. Never test-fit by force or rely on a connector that is loose in the laptop.
- Read the laptop’s underside label, service documentation or original charger output and confirm it matches the listed 19.5V-class HP input, required current and the exact blue-ring centre-pin jack.
- Compare the laptop jack with the exact blue-ring round HP-style plug with centre pin; outer/inner diameter and insertion length must be measured or documented; check outer shape/diameter, inner pin or aperture, insertion length and fit.
- Select a certified USB-C PD charger that exposes the required voltage and enough current/wattage, then select a USB-C cable rated for that load.
- With the equipment unpowered where practical, inspect all contacts for debris, corrosion, bent pins or looseness.
- Connect the USB-C cable firmly between the PD source and the tip, then insert the DC plug straight into the verified laptop jack without twisting.
- Energise the charger and confirm the laptop reports normal charging rather than an unsupported/slow adapter warning.
- During the first use, observe the tip, cable and laptop jack for abnormal warmth, smell, flicker or intermittent charging under normal load.
- Disconnect by holding each connector body. Remove mains power before changing parts in an uncertain setup.
Match the whole chain
Compatible devices and systems
Compatibility is determined by the complete power chain, not the laptop brand name alone. Model lists are examples only when physical and electrical requirements match.
- Selected HP laptops with the exact blue-ring round HP-style centre-pin connector and supported electrical requirement.
- Systems matching listed 19.5V HP examples drawing approximately 2.31A to 3.33A within the supported power class.
- USB-C PD wall chargers that explicitly offer the needed output profile and sufficient sustained wattage.
- USB-C cables rated for the required current; higher-current profiles may require a compliant electronically marked cable.
- Mains regions supported by the separate charger; the tip itself does not connect directly to AC power.
- Laptops whose DC input and battery/charging circuit are undamaged and within manufacturer specification.
- Not automatically compatible with every HP notebook, USB-C-native laptop, gaming model or machine using a visually similar connector.

Good practice
What to do
- Photograph or write down the original charger output and laptop model before selecting the source, cable and tip.
- Match physical connector shape, electrical output and required wattage across the complete chain.
- Use a certified USB-C PD charger and an appropriately rated, undamaged USB-C cable.
- Insert and remove by the connector bodies, keep the right-angle tip strain-free and support the cable on a desk.
- Watch the first full charging session and stop for any unsupported-adapter warning, instability or abnormal heat.
- Return to the manufacturer-approved charger when compatibility cannot be verified or the laptop has a damaged socket.
Avoid these mistakes
What not to do
- Do not choose by brand logo, colour or approximate barrel diameter alone.
- Do not force the plug, rotate it under load, bend the laptop jack or continue with a loose/intermittent fit.
- Do not connect a non-PD USB source, an under-rated cable or an unknown barrel-power supply into the USB-C input.
- Do not chain this tip with another DC converter, polarity reverser, barrel-size adapter or power bank whose required profile is unverified.
- Do not exceed the exact supported power/electrical guidance or use it with a laptop requiring a higher-power adapter.
- Do not leave a new or uncertain charging combination unattended, covered by bedding or exposed to moisture.
Important safety and performance notes
Warnings and limitations
Incorrect laptop power can damage the charger, cable, tip or computer. A plug that physically fits is not proof of electrical compatibility.
- Verify voltage, current capability, wattage, connector geometry and any centre-pin/identification requirement before connection.
- The charger may redistribute power when another port is connected. Confirm the laptop still receives the necessary profile in multi-device use.
- An underpowered source can cause battery drain while plugged in, slow charging, repeated negotiation or system shutdown under load.
- Abnormal heat at the tip often indicates poor contact, an overloaded cable/source or a damaged jack. Disconnect immediately.
- Do not use around liquid, a swollen battery, exposed conductors, a cracked charger or a loose/sparking laptop socket.
- High-power USB-C cables can look identical to low-rated cables. Use known specifications, not appearance.
- This accessory should not be used to diagnose unknown electronics or to bypass the laptop manufacturer’s safety limits.
Keep it working and solve common issues
Care, troubleshooting and buying checklist
When charging fails, test the original charger first and change one part at a time: PD source, cable, tip and laptop jack.
- No charging: verify the charger offers the required PD profile, use a known high-current cable and reseat both ends.
- Slow-charger warning: the source/cable may provide insufficient wattage, or the laptop may require identification this chain does not satisfy.
- Charges idle but drains under load: the computer is consuming more than the negotiated input; use the correct higher-capability approved charger path.
- Connects and disconnects: stop using the setup, inspect for looseness/debris and test the original adapter to distinguish tip, cable and laptop-jack faults.
- Tip or jack becomes hot: disconnect from mains and laptop immediately; do not continue testing a poor or overloaded connection.
- Works until another device is added: the multiport charger is reallocating power. Remove other loads or use a dedicated compliant source.
- Buying check: verify the exact blue-ring round HP-style plug with centre pin; outer/inner diameter and insertion length must be measured or documented, original adapter output, required wattage, PD charger profiles and cable current rating.
