Reviewed with: ASUS ROG Zephyrus G15 (GA503QE-HQ070T)

Setup & First Impressions

I found the SlimQ 240W SuperCharger while hunting for a second power brick for my laptop. Ordering was straightforward and shipping was quick. In the box, the charger arrives in tidy, protective foam with an assortment of international plug adapters. I’d also ordered the ASUS DC tip kit — two tips were included, and one matched my Zephyrus G15 perfectly. Within minutes I was plugged in and charging.

What’s in the Box?

• F240 GaN desktop charger
• DC-to-DC cable (1.8 m)
• US plug AC cable (1.5 m)
• International adapter pack (UK, AU, EU, DE/KR)
• Optional: DC tip set (ASUS kit used for this review)

Design & Build

The SlimQ’s design stands out: clean lines, compact footprint, and a fabric-like texture on the sides that makes it easy to grip and orient. The status LED is tastefully dim, and the figure-8 (C7) AC inlet feels secure. Two USB-C ports sit alongside the DC output, so you can power a laptop and fast-charge phones/tablets at once.

Performance & Testing

I stress-tested the SlimQ with my Zephyrus G15 under load while charging an iPad Pro and an iPhone 12 Pro via the two USB-C PD ports. The charger handled the triple-load without complaint: the LED stayed steady, temperatures remained comfortably cool to the touch, and there were no hiccups or throttling. After a few days, I retired my separate laptop brick and travel PD charger — this one unit did it all.

Compatibility notes

• Laptop DC output is tip-dependent — make sure you buy the right tip kit for your brand.
• Both USB-C ports can deliver up to 100W (total output will split dynamically depending on connected devices).

Quirks & Gotchas

• Bulky wall plug geometry: The included AC lead angles upward before dropping down. In tight spaces or recessed power boards, clearance can be an issue. A third-party, low-profile C7 cable fixes this neatly.
• Tight C7 inlet: The figure-8 port on the unit was very snug at first and nicked the plug’s plastic during the first insertion/removal. It loosened slightly with use, but take care on first setup.

The Good & The Could-Be-Better

• Pros
  • Genuinely replaces a laptop brick and a dual-USB-C fast charger
  • Cool, quiet operation under sustained, mixed loads
  • Wide protocol support (PD3.0/PPS/QC, etc.) and swappable DC tips
  • Travel-ready with international plug adapters in the box
  • Compact, premium build and subtle status LED
• Cons
  • Included AC cable shape isn’t friendly to recessed power boards
  • Very tight C7 inlet out of the box

Verdict

SlimQ 240W SuperCharger is a powerful, portable charging hub that earns its place in a tech bag — especially for gamers, creators, or anyone juggling a power-hungry laptop plus USB-C devices. With robust multi-device performance and thoughtful design, it trimmed my daily carry from multiple bricks to just one. The only real nitpicks are the stock AC cable geometry and a stiff C7 inlet. If you can live with (or swap) the cable, this is an easy recommendation.
