Nick Jennison reviews a portable and powerful little amp, packed with "smarts." The Mooer F15i Li Intelligent Amplifier squeezes modelling, Bluetooth, and battery power into a super-compact combo. With tons of amp voices, onboard effects, and an intuitive app for deep control, this little amp punches way above its weight. puts this through its paces for players on the move.
The Mooer F-15i Li isn't your average battery-powered practice amp. It's small enough to fit on your desk or in a backpack, but packed with features you'd expect to see on something much bigger—and a lot more expensive.

The "Li" stands for lithium-ion, and that rechargeable battery is the real heart of the F-15i Li. No power cable required. Whether you're jamming in the living room, taking it to a lesson, or playing in the park, you're never tied down by needing an outlet. Mooer's made this amp truly portable, and it still feels like real, quality gear.
The touchscreen is genuinely easy to use—just swipe and tap your way through amp models, effects, drum loops, and a built-in looper. For those who love deep editing, the Mooer iAmp app steps it up. Connect with Bluetooth, and you can build out your signal chain visually, rearrange effects, tweak settings, and dive into a growing library of user-shared presets. You're not just stuck with factory sounds—you can explore, create, and share your own.
What really impresses is the sound. The F-15i Li's onboard speakers are lively and dynamic, and the amp models cover a lot of ground—everything from clean, classic tones to full-throated lead sounds like the "Cali Mark 3" preset. If you want even more depth and clarity, just plug into headphones or monitors with the line out. For such a compact amp, it really holds its own, whether you're practicing quietly at home or tracking quick ideas in a project studio.
The F-15i Li is loaded with genuinely useful practice tools. Drum loops across various styles make it way more inspiring than a metronome, and the built-in looper works smoothly, letting you layer parts and get creative. There's a tuner built in as well, accessible both from the amp and the app. And if you want to jam to your favourite songs, Bluetooth streaming is ready to go.
You're not limited to practice, either. There's USB out for recording straight into your DAW, a mixer section for balancing guitar and backing tracks, and an optional Bluetooth footswitch if you want hands-free control at a rehearsal or even a small gig. The F-15i Li is as comfortable on a desktop as it is in a gig bag.
Design-wise, Mooer keeps things clean and compact. The amp looks sharp enough for any living space and won't clutter up your setup. It's the kind of amp you can actually leave out and use every day, not just stash away between sessions.
The Mooer F-15i Li is the rare small amp that doesn't ask you to compromise. It's packed with smart features, sounds great for its size, and is built for real guitarists who want portability and flexibility without sacrificing tone. If you're looking for an amp that will actually make you want to pick up your guitar and play—wherever you are—this one deserves a spot on your shortlist. Mooer has raised the bar for what a battery-powered practice amp can do.
