Some speakers try to do everything and end up doing nothing well. The Kamasonic S-113BT portable wireless Bluetooth speaker takes the opposite approach: it does the essentials honestly — 5W of clear, distortion-free sound from a 78mm driver, a 1200mAh battery that keeps the music going, and simple Bluetooth plus AUX connections that work with whatever device you already own. The kamasonic s-113bt is the kind of speaker that lives on a shop counter, a study desk, or a rooftop at dusk and just works, day after day.
The Bluetooth standard behind this speaker’s wireless connection is maintained by the Bluetooth Special Interest Group, the industry body that oversees the Bluetooth technology used to pair with your phone.
This is a budget pick that refuses to feel cheap. The kamasonic s-113bt pairs a sturdy, rugged body with a straightforward feature set: wireless Bluetooth for cable-free pairing, a 3.5mm AUX input for wired devices, and a battery built for extended playtime. It is made for buyers who want fuss-free music without the learning curve — switch it on, pair your phone, and the room has sound.
One honest note before we go further: the store’s own naming is inconsistent — the title says S-113BT, the specs table reads S113ST, and the badge on the grille reads S-113ST. This listing uses the title form S-113BT throughout and flags the mismatch so you know exactly what to confirm with the store when ordering.
Design and Build

The kamasonic s-113bt wears its job on its sleeve. The body is a compact, rugged rectangle with a textured front grille, chunky corner bumpers, and a carry strap — a design that looks comfortable being tossed in a bag or parked on a shop counter. Controls sit on the top panel where your thumb expects them, and the whole unit feels dense and solid rather than hollow.
The product photos also reveal extras the written specs never mention: a built-in LED flashlight on the side, a telescopic FM antenna, and a solar panel on the top face — the retail box even carries a “Solar charging” label. This listing treats these as photo-visible features only, never as confirmed specifications, because the store’s written copy does not document them. They appear in the photos; the specs table stays silent.
Sound and Performance

Sound is where the kamasonic s-113bt earns its keep. A 78mm driver pushes 5W of output with a signal-to-noise ratio of 80dB or better — the combination the page credits for its clear, distortion-free audio. In practice that means vocals stay intelligible, music sounds full at moderate volumes, and the speaker stays composed instead of crackling when you turn it up.

The 78mm driver is large for a speaker this compact, and that size is doing real work: bigger drivers move air more easily, which is why the kamasonic s-113bt sounds fuller than its small body suggests. Bluetooth handles the wireless link to phones, tablets, laptops, and PCs, while the AUX input keeps older or non-Bluetooth devices in the game. For music, calls, and media — the three uses the page names — the speaker covers home, office, and outdoor listening without fuss.
Battery and Charging

A 1200mAh rechargeable battery powers the kamasonic s-113bt, and the page describes it as built for extended playtime. That capacity is generous for a 5W speaker: the modest output sips power, so a full charge stretches across long listening sessions rather than dying mid-evening. Recharging happens over USB with the included charging cable — plug it into any phone charger, laptop port, or power bank.
The retail box also shows a solar panel on the top face labeled “Solar charging”. The written specs do not confirm solar charging, so this listing does not promise it as a feature — but the panel is clearly visible in the product photos, and it is part of why this speaker suits village trips and outdoor days where a wall socket is not nearby. Treat the solar top as a photo-visible bonus, not a documented spec.
Controls and Features

Controls stay simple on the kamasonic s-113bt: top-panel buttons handle power, pairing, volume, and track changes, so there is nothing to learn. The built-in LED flashlight — visible in the product photos but absent from the written specs — turns the speaker into a load-shedding companion: light and music from one box on a dark night. The photos show the flashlight on the side of the unit, throwing a genuinely useful beam.

The telescopic FM antenna is the other photo-visible extra worth knowing about. The written specs do not list an FM radio, but the antenna is unmistakable in the photos — extended, it is made for pulling in radio stations where the phone signal is weak or where you simply want the news without streaming. As with the flashlight and solar panel, this listing describes the antenna as shown in the product photos, not as a confirmed specification.

Every figure above comes from the live product page for the kamasonic s-113bt. Bluetooth version, exact dimensions, weight, charging time, and playtime hours are not published on the page, so they are omitted rather than estimated. The flashlight, antenna, and solar panel are described only as photo-visible features because the written specs do not document them.
What’s in the Box

The product page publishes a packaging list for the kamasonic s-113bt, and it is refreshingly complete: the speaker itself, a 3.5mm AUX cable for wired listening, a USB charging cable, and a user manual. Nothing here is invented — these four items are exactly what the page’s “Packaging Content” section lists, so you know precisely what arrives in the parcel.
Why the Big Driver Matters More Than the Watt Number
Buyers comparing small speakers usually shop by watts, but on the kamasonic s-113bt the more telling number is 78mm — the size of its single driver. A larger driver moves more air with each stroke, which is how a compact body produces sound that feels full rather than thin: voices carry weight, music has body at moderate volume, and the speaker does not need to strain to be heard across a room or a courtyard. The 5W output is modest on paper; the driver size is why it does not sound modest in person.
The second number worth translating is the signal-to-noise ratio of 80dB or better. In plain terms, it describes the gap between the music and the background hiss electronics produce — the wider the gap, the cleaner the sound, especially at low volume where hiss would otherwise compete with quiet passages, dialogue, and late-night listening. Together, the two figures explain the page’s description of clear, distortion-free audio: a big driver doing relaxed work, and a clean signal feeding it. The kamasonic s-113bt is a useful reminder that honest, well-matched numbers beat inflated ones.
Made for the Hours When the Power Is Not
Bangladesh has a use case no foreign spec sheet plans for: load-shedding. This speaker fits it naturally. The 1200mAh battery and a frugal 5W appetite mean long sessions between charges, and recharging is a USB cable plugged into any phone charger, laptop port, or power bank — the kind of charging that can happen whenever power briefly returns. On a shop counter, it keeps the day musical through cuts; on a study desk, revision playlists survive the outage uninterrupted.
The product photos suggest the designers had the same hours in mind: they show a built-in LED flashlight on the side and a telescopic FM antenna on top — one box offering light, music, and radio when the grid goes down. To be precise about the evidence, those extras are photo-visible only: the written specifications do not document them, and this page will not upgrade them to confirmed features. What is confirmed is enough on its own — a rugged body with corner bumpers and a carry strap, simple top-panel controls nobody needs a manual to learn, and sound for music, calls, and media at home, in the office, or outdoors.
The same build suits travel. The carry strap and the bumpers make it a speaker you toss in a bag for a village trip or a rooftop night without wrapping it in cloth first, and because the box already includes the AUX and USB cables, there is nothing extra to pack or buy. Set it down where the evening gathers, pair a phone, and it does its one job well until the power — everyone’s power — comes back.

How long does the battery last in real use?
The kamasonic s-113bt carries a 1200mAh rechargeable battery, which the page describes as built for extended playtime — but no exact playtime hours are published. Real-world runtime depends on volume: a 5W speaker sips power at moderate volumes, so expect long sessions, with louder playback draining the battery faster. If exact hours matter to you, ask the store before ordering.
How do I charge the Kamasonic S-113BT?
The speaker recharges over USB with the included USB charging cable — plug it into any phone charger, laptop port, or power bank. The page does not publish a charging time, so no figure is promised here. The retail box also shows a solar panel labeled “Solar charging”, but since the written specs do not confirm it, treat solar top-up as a photo-visible extra rather than a promised feature.
Which Bluetooth version does the Kamasonic S-113BT use?
The product page does not publish a Bluetooth version number for the kamasonic s-113bt, so this listing does not state one. What the page does confirm is wireless Bluetooth pairing with smartphones, tablets, laptops, and PCs, plus a 3.5mm AUX input for wired devices. If the exact Bluetooth version matters to you, confirm with the store before ordering.
Does the Kamasonic S-113BT really have a flashlight and FM radio?
The product photos clearly show a built-in LED flashlight on the side and a telescopic FM antenna on top — but neither appears in the page’s written specs or feature list. This listing describes them as photo-visible features, not confirmed specifications: they are in the photos, and the retail box even mentions solar charging, but the store’s written copy documents only Bluetooth, AUX, the 5W output, and the 1200mAh battery. If the flashlight or radio is the reason you are buying, confirm it with the store before ordering.
Can I get the Kamasonic S-113BT gift-wrapped?
Gadget Superb does not advertise a gift-wrapping service, so gift wrapping is not promised with this order. Buying the kamasonic s-113bt as a gift? Message the store on Messenger before ordering to ask what packing they can arrange.
What is the price of the Kamasonic S-113BT 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 kamasonic s-113bt page on Gadget Superb for today’s price — that is what you pay in cash on delivery, plus the standard delivery fee.
Why do some places call it S113ST instead of S-113BT?
That is the store’s own naming inconsistency, and it is worth knowing about: the product title says S-113BT, the specs table reads S113ST, and the badge on the grille reads S-113ST. It appears to be the same unit listed under slightly different model labels. This listing uses the title form S-113BT and recommends confirming the exact model with the store when ordering.
How do I clean and care for the speaker?
Wipe your kamasonic s-113bt with a soft, dry cloth and keep the grille free of dust. Keep it away from heavy rain — no water-resistance rating is published for this speaker. Store it in a dry place, avoid drops, and recharge with a standard USB charger, unplugging once full to keep the battery healthy.
What does the 80dB signal-to-noise ratio mean in practice?
It means the music sits at least 80 decibels above the speaker’s own background noise — a wide, clean gap. On the kamasonic s-113bt you hear it as clarity: vocals and dialogue stay intelligible at low volume, quiet songs are not veiled by hiss, and turning the speaker up does not bring a crackly edge with it. It is one of the figures behind this speaker’s clear, distortion-free sound.
Can I use the Kamasonic S-113BT with a laptop or PC that has no Bluetooth?
Yes — that is exactly what the AUX input is for. The box includes a 3.5mm AUX cable (alongside the speaker, a USB charging cable, and the manual, per the page’s packaging list), so a wired connection to a laptop, PC, or any device with a headphone socket takes seconds. The kamasonic s-113bt works with smartphones, tablets, laptops, and PCs either way: Bluetooth when wireless is available, AUX when it is not.
Will the solar panel charge the Kamasonic S-113BT on its own?
That is not something this listing can promise. The retail box shows a top panel labelled “Solar charging”, and the panel is visible in the product photos — but the written specifications do not confirm solar charging, so treat it as a photo-visible extra, not a documented feature. The confirmed charging route is the included USB cable into any standard charger or power bank. If solar charging is the deciding factor for you, confirm it with the store before ordering.
