Acer DC Adapter | 5.5x2.1mm | Up to 330W

5.5x2.5mm to 5.5x2.1mm DC Connector Adapter

Connect a compatible DC charger to your Acer laptop with the SlimQ DC connector adapter. This adapter converts a 5.5x2.5mm DC connection to a 5.5x2.1mm laptop-side plug and supports power delivery up to 330W (20V⎓16.5A).

Designed for compatible Acer laptops with a 5.5x2.1mm DC charging port. Before ordering, confirm your laptop’s connector size, required voltage, polarity and power requirements.

Use Your Compatible SlimQ DC Charger

Use this Acer DC adapter tip with a compatible SlimQ 150W, 240W or 330W DC charger, provided the charger meets your laptop’s electrical requirements.

This connector adapter does not convert voltage or increase charger output. Available power depends on the connected charger—for example, a 240W charger remains limited to its rated output when used with this adapter.

Check Your Acer Laptop’s Charging Port

Choose your adapter by the exact connector size and electrical requirements, rather than the Acer series name alone.

Before purchasing, check:

• Laptop connector: Your laptop must accept a 5.5x2.1mm DC plug.
• Charger connection: The charger’s DC cable must have a compatible 5.5x2.5mm male plug.
• Voltage and polarity: The connected charger must match your laptop’s requirements.
• Power: The charger must provide sufficient wattage for your laptop, without exceeding this adapter’s 330W rating.

A matching connector size alone does not establish compatibility. This adapter is not suitable for laptops requiring more than 330W.

Frequently Asked Questions

Q: What does the SlimQ Acer DC connector adapter do?
It connects a compatible charger cable with a 5.5x2.5mm male DC plug to an Acer laptop that accepts a 5.5x2.1mm male DC plug. It changes the physical connection size without converting voltage or increasing power.

Q: Is this a 330W Acer laptop charger?
No. This product is a DC adapter tip, not a standalone charger. It supports up to 330W at 20V⎓16.5A when used with a compatible power source and laptop.

Q: Will this adapter work with every Acer laptop?
No. It is intended for select Acer laptops with a 5.5x2.1mm charging port. Connector dimensions, voltage, polarity and power requirements must all match. Confirm your exact laptop model before use.

Q: Can I use it with a SlimQ 150W or 240W charger?
Yes, provided the charger meets your laptop’s voltage, polarity and wattage requirements. The adapter does not increase available power: a 150W charger cannot supply 240W or 330W through this adapter.

Q: Are 5.5x2.1mm and 5.5x2.5mm DC connectors interchangeable?
They have the same nominal outer diameter but different inner diameters. Do not assume they are interchangeable. This adapter provides a 5.5x2.5mm female connection on the charger side and a 5.5x2.1mm male connection on the laptop side.

Q: Can I use a non-SlimQ DC charger?
Only if its cable has a compatible 5.5x2.5mm male plug and its output voltage, polarity and power specifications meet your laptop’s requirements. Connector fit alone does not confirm electrical compatibility.

Q: How can I check compatibility before ordering?
Contact SlimQ with your laptop’s full model number and a clear photo of the original charger’s output label and connector. We will be happy to help you choose the appropriate adapter.

Connector dimensions are nominal. Small measurement variations may occur.
