Q: How long does the battery last on a full charge?

A: The built-in 1800mAh battery gives you up to 7 hours of continuous playback at moderate volume. Charging takes about 3 hours, so you can easily top it up overnight or while you’re getting ready.

Q: Can I use this speaker outdoors in light rain or near water?

A: Yes, it has an IPX4 rating, which means it’s protected against splashing water from any direction. It’s fine for poolside use, a light drizzle, or kitchen counter spills, but don’t submerge it or expose it to heavy rain.

Q: Does it support connecting two speakers together for stereo sound?

A: Absolutely. You can pair two K12 Air units wirelessly using TWS (True Wireless Stereo) mode to create a left-right stereo channel for a more immersive listening experience.

Q: What input options are available besides Bluetooth?

A: Besides Bluetooth 6.0, you can also play music via a 3.5mm AUX cable or directly from a TF/microSD card. This makes it easy to use with devices that don’t have Bluetooth, like older MP3 players or laptops.

Q: Is the bass really good at low volumes?

A: Yes, thanks to the exclusive low-frequency algorithm and dual passive diaphragms, you get noticeable bass punch even when the volume is turned down. It’s designed to deliver rich sound without needing to crank it up.

Q: What are the two EQ modes and how do I switch between them?

A: The speaker offers Home Leisure mode for balanced, warm audio ideal for indoor relaxation, and Outdoor Activity mode with boosted clarity and presence for open spaces. Switching is usually done by pressing a dedicated button on the speaker — check the manual for exact operation.

Q: How big and heavy is it? Can I take it in my backpack?

A: It measures 80×80×114mm and weighs only 385g, roughly the size of a small water bottle. It fits easily in a backpack, bike bottle holder, or even a large jacket pocket, making it very portable.

Q: Will it work with my phone if I’m standing 10 meters away?

A: With Bluetooth 6.0 and the AC6965E chip, the stable range is about 15 meters in open space. Walls may reduce that distance, but within a typical room or yard it should stay connected reliably.

Q: Can I use it while it’s charging?

A: Yes, you can play music through Bluetooth, AUX, or TF card while the speaker is plugged in and charging. Just keep in mind that charging time may be slightly longer if you’re using it simultaneously.

Q: How loud can it get? Is it enough for a small party?

A: With a rated power of 8W and peak power of 16W, it can fill a medium-sized room or a small outdoor gathering with clear sound. For larger parties, consider pairing two units via TWS for double the volume and stereo effect.
