Don't use retractable reels for continuous high loads.

No, not unless it’s a commercial-grade reel specifically rated for that, and even then I’d think twice.

The problem is heat. When a cord is coiled up on a reel, it can’t dissipate heat like a straight cord. Continuous high loads (space heaters, refrigerators, air conditioners, that sort of thing) generate enough heat to melt the insulation or trip the reel’s thermal cutoff. Most retractable reels use 16 or 14 gauge wire, which is too thin for sustained 15-amp draw. And the spring mechanism adds resistance at the connection points, which creates more heat.

There are heavy-duty reels (12 gauge, rated for continuous use) — but they’re expensive and usually meant for workshop tools, not permanent appliance connections. Even then, you’re better off running a dedicated circuit. Reels are for temporary use, not “leave it plugged in 24/7.”

This is not where you save time by avoiding an outlet installation.
