ELECBRAiN 240W Laptop Charger for Dell & Alienware

ELECBRAiN's 240W laptop charger is a high‑power replacement AC adapter designed to supply reliable 19.5V power for many Dell and Alienware gaming laptops and Precision workstations.

If your original Dell or Alienware brick is lost, damaged, or underpowered for your system, this ELECBRAiN replacement offers the same connector size (7.4mm x 5.0mm) and voltage output to run laptops that require up to 240 watts. The unit supports multiple power profiles (including compatibility with 180W, 150W and other 130W equivalents) and includes integrated protection circuitry to guard against common electrical faults. Below you’ll find clear answers to the most common buyer questions, plus the exact specs and compatibility notes so you can choose with confidence.

Which laptops and part numbers does this charger work with?

This adapter is built to fit a broad list of Dell and Alienware models, as well as many Precision series notebooks. Check the model lists and part numbers below to confirm compatibility before purchasing.

• Supports Dell G series: G3, G5, G7, G15, G16 (various model years)
• Compatible with Alienware: M13, M15, M17, M18X and R2–R5 series
• Precision and Latitude: multiple Precision M6xxx and Pxxx series listed in product details
• Matches common OEM P/Ns such as GA240PE1-00, DA240PM180, PA-9E and many OEM cross-references

How do the power specs and connector size affect use?

The adapter outputs 19.5V and up to 12.3A for a full 240W capability, with alternate compatibility for devices that accept 19.5V at lower amps (for example 9.23A/180W or 6.7A/130W). The plug is the standard barrel 7.4mm x 5.0mm tip—this is not USB‑C—so it will physically fit only devices that accept that barrel size.

• Output: 19.5V, 12.3A (240W); also compatible with 19.5V 9.23A (180W), 6.7A (130W)
• Connector: 7.4mm x 5.0mm barrel tip (not compatible with USB‑C chargers)
• Input range: universal 100–240V AC, 50–60Hz for worldwide use with appropriate plug

What safety and reliability features are included?

The ELECBRAiN adapter integrates an intelligent IC chip and surge protection to reduce the chance of damage from voltage spikes, overloads, and short circuits. These protections act as a triple‑layer safeguard but do not replace correct use or the laptop’s internal power management.

• Built‑in IC chipset for steady voltage regulation and thermal management
• Over‑voltage, over‑current and short‑circuit protection mechanisms
• Durable housing and strain‑relief on cables for extended daily use

How can I ensure this is the right replacement for my device?

Always match the required voltage, connector size and the recommended wattage printed on your laptop or original adapter. If your Dell or Alienware lists any of the compatible part numbers (for example GA240PE1-00 or PA-9E) or you have a model in the compatibility list, this charger is a suitable replacement.

• Confirm laptop voltage requirement: 19.5V is required for compatibility
• Verify connector size: 7.4mm x 5.0mm barrel tip required
• Check recommended wattage: use 240W for high‑power systems, 180W/150W options supported where appropriate

Who is this for: Professionals and gamers who need a robust, high‑wattage replacement power supply for Dell and Alienware laptops and Precision mobile workstations. Ideal for owners of power‑hungry systems (large GPUs or workstation CPUs) who require the correct 19.5V barrel connection and want built‑in electrical protections. Purchase this ELECBRAiN adapter if your device lists compatible part numbers or if you need a dependable 240W/180W replacement that reliably matches OEM power specifications.
