An IR blaster sends infrared signals—like a traditional remote—so you can control devices such as TVs, cable boxes, DVD players, soundbars, and many air conditioners. On this page, you’ll see options that plug into USB or USB‑C, smartphone adapters, universal remote hubs, and IR extenders for hidden AV gear.

• Use cases: Consolidate remotes, add app or voice control, reach devices in cabinets.
• Line of sight matters: Emitters need a clear path to the device’s IR sensor.
• Range varies: Check product details for distance and compatibility.

Setup typically involves connecting the blaster, installing an app, and selecting or learning device codes.

It depends on how your AC is controlled. Many AC units use IR remotes; for those, an IR blaster is usually the practical way to change modes, temperature, and fan settings. If you prefer alternatives, consider the following:

• Built‑in smart control: Some ACs have native Wi‑Fi apps. Check your manual.
• Smart plugs: Useful for on/off only. They don’t adjust temperature or modes.
• RF remotes: If your AC uses RF, look for a compatible RF bridge rather than IR.

Results vary by model. Verify your AC’s remote type, then choose a solution that fits the features you want.

A USB IR blaster dongle is a small adapter that plugs into a USB or USB‑C port to transmit infrared signals, letting a phone, tablet, computer, or hub act like a remote. It’s helpful for controlling TVs, set‑top boxes, audio gear, and some AC units.

• Compatibility: Match the connector (USB‑C, Micro USB, standard USB) and confirm OTG support on Android.
• App control: Most dongles use a companion app to select or learn device codes.
• Placement: Aim the dongle or its emitter toward the device’s IR sensor.

Range and features vary, so review the product details before buying.

You’ve got two common paths: a plug‑in IR adapter or a Wi‑Fi IR hub. Both let your phone send commands to TVs, cable boxes, soundbars, and certain AC units.

1. Plug‑in adapters: Choose USB‑C or Micro USB (with OTG). Install the app, select your device brand/model, and aim the adapter toward the IR sensor.
2. Wi‑Fi hubs: Place the hub near your devices, connect to your home Wi‑Fi, and use the app to add and test commands.

For equipment inside cabinets, consider IR extenders. Compatibility and performance can vary by device and setup.

Both can control IR devices; the right pick depends on how you want to use them.

• USB/USB‑C adapter: Portable and simple. Great for one user controlling gear from a phone. Requires your device to be plugged in and pointed at the IR sensor.
• Wi‑Fi IR hub: Stays in the room, controls multiple devices, and can work with apps and some voice assistants. Often better for shared households and schedules.
• Hidden gear: If equipment is in cabinets, look for hubs with emitters or add IR extenders.

Check compatibility, setup requirements, and range in the product details.
