HP Elite Dragonfly G3 original USB-C AC-adapter 110.0 Watt rounded + USB-A

It's very easy - in just a few steps:

1. Enter your laptop model:
   Enter the exact model of your laptop in the search field at the top of the IPC Computer website (e.g.Lenovo ThinkPad T14 or HP ProBook 450 G7).
2. Select the power supply unit product group:
   In the results list, you will find the power supply units directly after the batteries.
3. Compare performance:
   If your model is offered with several power supply units (e.g. 65 W or 90 W), take the power supply unit that has the same output as your previous power supply unit.
   - This output is usually written on the old power supply unit in the "Output" line (e.g. 19.5 V - 3.34 A = 65 W).
4. No more old power supply unit?
   No problem: Look on the bottom of your laptop for the entry "DC Rating"or "Input " - there you will find the voltage (V) and current (A). These values give you the required power (V × A = W).
5. Select original:
   In our store, you will only be shown original power supply units that are an exact technical match for your model. This means you are on the safe side when it comes to performance and compatibility.

Tip: If you are unsure, you can also send the name of your device or photos of the rating plate of the old power supply unit to our service team - we will help you find the right power supply unit free of charge.

If your laptop does not charge via USB-C, this is usually not due to a defect, but to compatibility or performance problems. USB-C uses the power delivery standard (USB-PD), which must be supported by both devices.

The most common causes:

• Too little power: For example, your power supply only delivers 45 W, but your laptop requires 65 W or more.
• Unsupported protocol: The power supply or laptop do not speak the same USB PD standard.
• Poor or defective USB-C cable: Not every cable transmits the required power - especially with fast charging functions.
• Dirty or damaged USB-C port: Dust or scratches in the port prevent a stable connection.
• Firmware or BIOS settings: Some manufacturers disable USB-C charging in the BIOS or limit it in case of overheating.

Troubleshooting tips:

1. Power supply check: Always use a USB-C power supply with sufficient power and USB-PD certification.
2. Cable test: If problems occur, test another certified cable.
3. System reset: If the laptop is still not charging with the original USB-C power adapter, a BIOS update or a brief power reset (disconnect the battery and power adapter, press and hold the power button for 30 seconds) will often help.

Caution: You can tell that charging is working if the charging indicator reacts immediately and the power supply unit clicks or hums briefly. If this does not happen, there is almost always a compatibility problem.

Inside a power supply unit are components that convert the mains voltage (e.g. 230 V) into the right voltage for your laptop. GaN power supply units use gallium nitride semiconductors for this purpose.

This has several advantages:

1. Smaller & lighter
   • For the same output power (e.g. 65 W, 100 W or 240 W), a GaN power supply unit can be built much more compactly.
   • Ideal for on the go, in the home office or if you have little space in your bag.
2. Higher efficiency, less waste heat
   • GaN components work more efficiently, so less energy is lost in heat.
   • Although the power supply unit does get warm under load, it generally runs more smoothly and can be more durable.
3. High performance in a small space
   • Very powerful power supply units (e.g. 100 W, 240 W) are also possible with GaN in a relatively small form factor .
   • This is exciting if you want to operate a powerful laptop, a docking station or several devices with one power supply unit.

Important: GaN power supplies are currently still somewhat more expensive than conventional laptop power supplies. The combination of compact form factor and proven quality makes them an attractive choice for many customers.

Modern laptop power supplies are so-called switching power supplies - they work with very high switching frequencies and should function practically silently. If you still hear a humming, hissing or whirring noise, this is not normal and often indicates a technical defect or inferior components.

Typical causes are

• loose or poorly potted coils and capacitors,
• incorrect switching frequency or inadequate filtering,
• component wear or voltage problems in the mains supply.

Such noises hardly ever occur with original power supply units as they undergo strict quality and safety tests. Replica power supply units, on the other hand, often use simple components without sufficient interference suppression - here, humming or hissing is a clear warning sign.

Important: If a power supply unit hums or hisses audibly, stop using it!

Disconnect it from the power supply immediately and dispose of replica power supply units immediately, as they can pose a safety risk. Only use original power supply units to ensure a stable, quiet and safe power supply for your laptop.

Many years of experience in laptop repair clearly show that you should use original power supply units or tested branded power supply units wherever possible and not cheap replicas because:

• Safety:
  High-quality power supply units have tested protective circuits and deliver a stable voltage. Cheap replicas often cut corners here - in the worst case, this can damage the electronics or the battery.
• Compatibility:
  Original power supply units are precisely matched to your device (voltage, power, plug, recognition by the notebook). With "any" replicas, problems such as "power supply is not recognized", "does not charge properly" or performance drops under load occur more frequently.
• Reliability:
  A good power supply should simply work inconspicuously. Original or OEM power supplies are generally more durable and fail-safe than very cheap no-name products, which often lack quality and final inspection.
• Cost-effectiveness:
  The surcharge for an original power supply unit is significantly lower than the costs for a possible repair of the mainboard, charging electronics or battery. You also save yourself the hassle of returns and incorrect purchases.

The bottom line is that an original or OEM power supply unit is often a little more expensive, but you get maximum safety, full compatibility and less risk - and that is precisely what is crucial for a safety-relevant component such as the power supply unit.

→ In the Store section "Notebook power supplies" you will find a large selection of original and tested quality power supply units.

No, just because the power supply has more watts, your battery will not automatically charge faster. The decisive factor is the power required by your laptop and the permissible power of the charging electronics - not the maximum power of the power supply unit.

How does charging work technically?

• Every laptop has built-in charging electronics that regulate exactly
  • how much current flows into the battery and
  • how quickly or gently the battery is charged.
• The power supply unit only provides the maximum possible power - it does not "force" this power into the laptop.
• Your laptop only "takes" as much power as it is designed for.

This means:
If your laptop is only designed for 65 W, for example, a 90 W or 120 W power supply alone will not provide a turbo charging advantage. The device limits the charging current itself.
