AWEI KA51 12W TWS Surround Stereo Bluetooth Speaker with RGB Lights & 1800mAh Battery

A great party speaker does two jobs at once: it fills the room with sound and it looks like the party. The Awei KA51 TWS does both — a compact 12W bar speaker with dual full-range drivers and a dynamic RGB light strip along its front edge that moves with the music. The awei ka51 tws is built for home parties, picnics, travel, and everyday listening, with an 1800mAh battery that plays up to 6–8 hours and a built-in mic for hands-free calls.

Pair two of them and the awei ka51 tws doubles the soundstage: true wireless stereo pairing links two KA51 units into one wider left-right system, so a big room gets real stereo instead of one louder box. Add the splash-resistant build and USB-C fast charging, and you have a speaker that travels as well as it parties.

This page is written from the verified research notes for this speaker. Every number below comes from those verified notes — nothing here is estimated, and anything not confirmed is stated as omitted rather than guessed.

Design and Build

The awei ka51 tws is a compact black bar with a fabric-mesh front, a small “awei” badge, and a thin RGB light strip running along the bottom front edge. The slim, low-profile shape sits naturally on a side table or a picnic mat, carries one-handed, and slides into a backpack.

One clarification: “TWS” in this model name refers to the pairing feature — link two KA51 units and they play as one wider stereo system. Gadget Superb also carries the Awei KA51 soundbar variant in the same model family; this listing is the portable TWS variant with the RGB light strip, which is why it is the pick for parties and travel. Some retailers use the “KA51” name for the soundbar form, so check that the listing you are comparing mentions the RGB lights and TWS pairing before assuming they are the same product.

The build is splash-resistant: light splashes — rain drizzle at a picnic, spray near a pool — are fine. It is not rated waterproof, no IPX figure is published, and the awei ka51 tws should not be submerged or left out in heavy rain.

Sound and Performance

Twelve watts from dual full-range drivers gives the awei ka51 tws a balanced stereo image with real bass weight for its size — loud and clear enough for a living-room party, an adda, or a picnic mat, without the thinness that plagues cheaper portables. Vocals stay intelligible at volume and treble stays clean, which matters for playlists that swing from Bangla pop to movie nights.

The awei ka51 tws is honest about what it is: a compact bar that fills a room, a rooftop, or a picnic spot — not a concert rig.

The headlining trick is TWS: pair two awei ka51 tws speakers and they play as a left-right stereo pair. One unit is a strong portable speaker; two become a small stereo system with genuine width.

RGB Lights That Move With Music

The RGB light strip along the front edge is the awei ka51 tws signature: dynamic RGB effects that sync with playback, washing the table or wall under the speaker in moving color. It turns a quiet evening into a mood and a party into a light show.

The lights can be toggled to match the mood, so the awei ka51 tws works as a plain black bar speaker when you want it to. Leave the strip on for parties and late-night sessions; switch it off for daytime listening. This is a real toggle, not a gimmick you are stuck with.

Battery and Charging

The 1800mAh battery plays up to 6–8 hours per charge, per the manufacturer — a full evening adda, a day trip, or a long picnic on one charge. Battery figures are per-manufacturer figures, and real-world playtime moves with volume and lighting: maximum volume with the RGB strip blazing drains faster than moderate volume with the lights off. For the longest sessions, keep the volume moderate and the lights off.

USB-C fast charging gets the awei ka51 tws back to the music quickly when it does run down. Charging time in minutes is not published, so no figure is stated here. Top it up between outings and it is ready whenever the plan comes together.

TWS Pairing and Hands-Free Calls

TWS (True Wireless Stereo) lets two awei ka51 tws units link wirelessly and play as one wider stereo system. Power on both KA51 speakers, double-click play on one to pair them, and they act as a single left-right system for bigger rooms and outdoor gatherings.

The built-in microphone adds hands-free calling with clear voice pickup: take a call straight through the awei ka51 tws without reaching for your phone. It is a convenience feature for everyday use — a quick call while cooking, a virtual meeting at your desk — and it is why this speaker earns a permanent spot on a work desk as well as a party table.

Specifications

All figures are taken from the verified research notes for this speaker. Exact Bluetooth sub-version, charging time, frequency response, dimensions, weight, IPX rating, and box contents are not published, so they are omitted rather than guessed.

What’s in the Box

The verified research notes do not publish the box contents for the awei ka51 tws, so no item list is stated here rather than guessed. If any accessory matters — for example whether a USB-C cable is included — confirm exactly what ships with Gadget Superb on Messenger or at care@gadgetsuperb.com before ordering.

One Bar or Two: How TWS Changes the Room

A single awei ka51 tws already does the job its shape promises. Set the bar on a side table, a desk, or a picnic mat with the fabric-mesh front facing the listeners, and the dual full-range drivers lay a balanced stereo image across the seating — vocals in the middle, instruments spread either side — from one compact unit that carried in one hand. For a living room, a rooftop adda, or a picnic circle, that is a complete setup: power on, pair over Bluetooth 5.x, and the room has music.

The second unit is where the character changes. TWS pairing links two awei ka51 tws speakers into one true left-right stereo system — power both on, double-click play on one, and they divide the channels between them. Placed apart on opposite sides of the seating, the pair throws a soundstage noticeably wider than any single bar can: film dialogue stays anchored in the centre while music and effects open out to the edges, and a bigger room or an outdoor gathering gets even coverage instead of one loud corner and one quiet one. It is the difference between a speaker playing at a gathering and a small stereo system hosting it.

The practical pattern most owners settle into is one of each. One unit lives the everyday life — desk, kitchen, travel bag — and when a party, a movie night, or a rooftop plan actually needs the width, the second unit comes out and the pair takes over. Nothing about the first speaker changes or goes to waste; it simply gains a partner.

Making 6–8 Hours Last the Whole Event

The 1800mAh battery’s up-to-6–8-hours figure, per the manufacturer, covers a full evening adda, a day trip’s listening, or a long picnic on one charge — and a few habits decide which end of that range you land on. Volume and light are the two appetites: maximum volume with the RGB strip blazing is the fastest drain, while moderate volume with the lights off is the longest road. For a daytime picnic where the light show adds little, switching the strip off is free playtime; save the full lighting for the evening sessions where it earns its keep.

Charging fits around the plan rather than interrupting it. The awei ka51 tws refills over USB-C fast charging — the exact full-charge time is not published, so plan a top-up before you head out rather than timing it to the minute — and the port is the same modern Type-C most phones now use, so the speaker and your phone share one charging habit at home and one cable on the road. Topped up before the event, it simply plays.

The rest of the routine is placement and weather sense. The splash-resistant build shrugs off picnic drizzle and poolside spray, but it is fair-weather protection, not waterproofing — bring it under cover when the rain turns serious. At the end of the day the compact bar goes back into the backpack it arrived in, ready to do the same job somewhere else tomorrow.

Frequently Asked Questions

Is the Awei KA51 TWS the same as the Awei KA51 soundbar?

Same model family, different listing. This page is for the portable awei ka51 tws — the compact bar with the RGB light strip and TWS stereo pairing, built for parties and travel. Gadget Superb also lists the Awei KA51 soundbar variant; some retailers use the “KA51” name for the soundbar form, so check that the listing you are comparing mentions the RGB lights and TWS pairing before assuming they are the same product.

Is the Awei KA51 TWS an original Awei product?

This listing is for this model as catalogued by Gadget Superb under the Awei brand. The store does not claim official-distributor status for any brand it carries. If authenticity documentation matters to you, message the store on Messenger or email care@gadgetsuperb.com before ordering.

Does this speaker come with a warranty?

Yes — this speaker includes a 7-day store warranty. If a warranty matters to you, confirm the terms with the store — hotline 09638054751, care@gadgetsuperb.com, or Messenger — before placing your order.

How long does the battery last on the Awei KA51 TWS?

The 1800mAh battery plays up to 6–8 hours per charge, per the manufacturer. Real-world playtime moves with volume and lighting — max volume with the RGB strip on drains fastest. Keep the volume sensible and the awei ka51 tws will stretch toward the upper end of that range.

How does TWS pairing work on the Awei KA51 TWS?

Power on both KA51 speakers, then double-click the play button on one to pair — they link wirelessly and play as one wider stereo system, one speaker per channel. One awei ka51 tws is a strong portable speaker; two become a small stereo system for a room, a rooftop, or an outdoor gathering.

Can I take calls on the Awei KA51 TWS?

Yes. The built-in microphone supports hands-free calling with clear voice pickup — answer straight through the speaker without picking up your phone. It is a convenience feature for quick calls, and it earns the awei ka51 tws a spot on the desk as well as the party table.

Can I turn the RGB lights off?

Yes. The RGB effects can be toggled to match the mood — on for parties and evening sessions, off for daytime listening. With the lights off, it is a plain, understated black bar speaker.

Is the Awei KA51 TWS waterproof?

No — it is splash-resistant, not waterproof. Light splashes and drizzle are fine, but no IPX rating is published, and the speaker should not be submerged or left in heavy rain. Treat it as a fair-weather outdoor speaker, not a shower or pool speaker.

How long does delivery take, and what are the charges?

Inside Dhaka, delivery costs ৳70 and takes 1–3 working days; outside Dhaka, it costs ৳120 and takes 2–5 working days. These are estimates, not guarantees.

How does cash on delivery work? Can I check the speaker before paying?

Cash on delivery means you pay the courier in cash when the parcel arrives. Gadget Superb never asks for advance payment, card details, OTPs, or mobile-banking PINs. Couriers generally do not allow opening a parcel before payment, so check your speaker right after the courier leaves.

What is the return policy if my Awei KA51 TWS arrives faulty?

Every Gadget Superb product carries 7-day easy returns. If it arrives damaged or faulty, keep it in its original condition with box and accessories, then start a return with your order number via hotline 09638054751, care@gadgetsuperb.com, or Messenger.

What is the price of the Awei KA51 TWS in Bangladesh?

The current price is shown on the product page and can change during sales, so no figure is quoted here. Check the live page on Gadget Superb for today’s price — that is what you pay in cash on delivery, plus the standard delivery fee.

Where should I place the KA51 for the best sound?

On a flat, stable surface — a side table, a desk, a picnic mat — with the fabric-mesh front and its RGB strip facing the listeners, since the dual full-range drivers project forward from the bar. Keep it out in the open rather than boxed into a shelf corner, and the stereo image opens up properly. If you run two awei ka51 tws units as a TWS pair, place them apart on opposite sides of the seating so the left and right channels have real distance between them.

How long does it take to charge?

The exact charging time is not published in the verified research notes, so this listing does not quote one. What is confirmed is USB-C fast charging on the 1800mAh battery: it refills quickly enough that a top-up before an outing is the sensible routine, rather than a long planned charge. If a precise charge-time figure matters to your use, confirm it with the store before ordering.

Is one enough for a party, or should I buy two?

One is enough for most rooms. A single awei ka51 tws fills a living room, a rooftop, or a picnic spot with 12W of dual-driver stereo, and that covers the typical adda or family gathering. Buy the second unit when your spaces get bigger — a large room, a wide rooftop, an outdoor gathering — because two units paired over TWS play as one wider left-right system with genuinely broader coverage. Start with one; the pair is an upgrade you can add later, and the first speaker loses nothing by it.
