The Portronics Bubble is a compact, tenkeyless wireless keyboard that connects over both Bluetooth 5.0 and a 2.4 GHz USB receiver, and Portronics says it can pair with up to three devices and switch between them with shortcut keys. Its main selling points are quiet, low-profile keys and a light 276-gram body, which make it a sensible pick for people who type on a tablet, a phone and a laptop from one desk. If you need a number pad, a backlight or a built-in rechargeable battery, look at other models instead.
This article covers the variant the affiliate link opens on Amazon.in, which is listed as the Portronics Bubble Multimedia Wireless Keyboard in Black. Portronics also sells the Bubble in White and Purple on its own website, so confirm the colour on the listing before you order.
How this article was put together: it is based on Portronics’ official product page, the Amazon.in listing title and published retailer and news listings, all checked on 17 October 2026. We have not tested this keyboard ourselves, so you will not find typing-feel impressions or battery-life measurements here, only what the sources actually state.
Quick verdict
- Best for: tablet and smartphone users who want a small physical keyboard, people who switch between a laptop and a phone through the day, and anyone typing in shared spaces or on calls where key noise matters
- Skip it if: you enter a lot of numbers (there is no dedicated number pad), you type in the dark (no backlight is mentioned), or you want a keyboard you recharge over USB-C
- Key strengths: dual-mode wireless (Bluetooth 5.0 and 2.4 GHz), up to three paired devices, 78 silent low-profile keys, multimedia hotkeys, auto-sleep, 276 g weight, 12-month warranty
- Key limitations: no official battery-life or range figure, battery type not stated on the official page, Bluetooth 5.0 is older than the 5.3 used by newer Bubble models, no built-in device stand

Two ways to connect, three devices to juggle
The headline feature of the Portronics Bubble is its dual-mode connection. The 2.4 GHz USB receiver plugs into a laptop or desktop and generally gives a plug-and-play link that does not depend on the computer’s own Bluetooth. That is useful on older desktops without Bluetooth, or on office PCs where Bluetooth pairing is restricted.
Bluetooth 5.0 covers devices that have no USB-A port, which is where the Bubble earns its “tablet keyboard” positioning. The Amazon.in listing title names iPad Air, iPad Pro and iPad mini, Android devices, Windows tablets, PCs and smartphones as targets. Pairing a keyboard with an iPad or an Android tablet turns it into a basic writing machine for emails, notes and documents without carrying a laptop.
Portronics says the Bubble can stay paired with up to three devices and that dedicated shortcut keys switch between them. In practice this means you could keep a laptop on the USB receiver and a phone and a tablet on Bluetooth, then hop from replying to a work email to answering a WhatsApp message without re-pairing. Portronics’ page does not spell out exactly how the three slots are split between Bluetooth and the receiver, so check the manual in the box for the exact key combination.
One honest caveat: Bluetooth 5.0 is older than the Bluetooth 5.3 used on the newer Bubble 2.0, Bubble 3.0 and Bubble 4.0. For a keyboard, which sends very little data, the practical difference is mostly about power efficiency and connection stability rather than speed, but it is worth knowing if you are comparing models in the Bubble line.
Layout and typing: compact, quiet and low-profile
The Bubble uses a tenkeyless (TKL) layout with 78 keys. TKL means the number pad on the right is dropped, which shrinks the keyboard so your mouse can sit closer to your typing hand and the whole thing fits in a backpack sleeve. The trade-off is obvious if you work with spreadsheets, billing software or GST entries all day: without a number pad, number-heavy work is slower.
Portronics describes the keys as silent, extra-soft and low-profile with low travel, and the Amazon listing title highlights a “noiseless experience”. Low-profile keys sit closer to the desk, so your wrists bend less, and Portronics claims this reduces finger fatigue during long sessions. The quiet keys are the more practical benefit: they suit open offices, hostel rooms, libraries and video calls where a clacky keyboard gets noticed. Portronics does not state whether the switches are scissor or membrane, so we cannot say how the keys feel compared with a laptop keyboard.
Multimedia keys and everyday convenience
The Bubble includes multimedia hotkeys for music playback, volume and screen control. On a tablet or phone these shortcuts save you from reaching up to the touchscreen every time you want to pause a song or change the volume, which is exactly the kind of small friction that makes a tablet keyboard pleasant or annoying.
Note that shortcut keys can behave differently across Windows, Android and iPadOS. Portronics does not publish a per-platform key map on the product page, so treat platform behaviour as something to check in the manual rather than an assumed feature.
Battery and power
This is the area where official information is thin. Portronics’ Bubble page mentions an auto-sleep mode that switches the keyboard off when it is idle to conserve battery, but it does not state the battery type, how many cells are needed or a battery-life figure.
Smartprix’s spec listing for the Portronics Bubble Wireless Keyboard shows it running on AAA batteries rather than a built-in rechargeable cell. We could not confirm this on Portronics’ own page, so check the “Technical details” section of the Amazon listing or the box before buying. If you specifically want USB-C charging, the Bubble 3.0 and Bubble 4.0 are officially listed with built-in rechargeable batteries.
Build and portability
At 276 grams, according to Portronics, the Bubble is light enough to carry with a tablet every day. The compact TKL footprint also helps on small desks, train tables and café counters. Portronics positions it as “travel-friendly”. Unlike the Bubble 3.0, Bubble 4.0 and Bubble Square (which, according to an ITVoice launch report, has a built-in holder), the official Bubble page does not mention any built-in stand or holder for phones and tablets, so you will need your tablet’s own case or a separate stand to prop the screen up.
Portronics lists three colours on its site: Black, White and Purple. The Amazon link in this article opens the Black variant.
Who should buy the Portronics Bubble
- iPad and Android tablet users who want a light, physical keyboard for writing and email
- Students and work-from-home users who switch between a laptop and a phone through the day
- People who type in shared rooms, libraries or on calls and want quiet keys
- Anyone with a small desk who prefers a compact layout so the mouse sits closer
Who should skip it
- Accountants, data-entry staff and anyone who needs a number pad every day
- People who type in low light, since no backlight is mentioned
- Buyers who want a rechargeable USB-C keyboard instead of replaceable batteries
- Anyone who wants a built-in tablet or phone stand on the keyboard itself
Alternatives worth comparing
These are other Portronics keyboards that solve the Bubble’s main limitations. Details are from Portronics’ official pages or named retailer listings, checked on 17 October 2026.
- Portronics Bubble 2.0: keeps the compact TKL idea but moves to Bluetooth 5.3 with a 2.4 GHz receiver. Reliance Digital’s listing says it connects up to three devices (one over the receiver and two over Bluetooth), quotes a 10 m range and an auto-standby after 10 minutes, and lists Windows, Android, iOS and macOS compatibility.
- Portronics Bubble 3.0: Portronics lists it as a full-size keyboard with an integrated number pad, Bluetooth 5.3 plus a 2.4 GHz receiver, a built-in rechargeable battery charged over Type-C, a dual-angle adjustable stand and Microsoft Copilot support. Better for number work and long desk sessions.
- Portronics Bubble 4.0: Portronics lists Bluetooth 5.3 with three connections plus a 2.4 GHz receiver for up to four devices, a full-size layout with a number pad, a built-in rechargeable battery with Type-C charging and an integrated holder for tablets and phones. The pick if you want one keyboard for four devices.
What to check before you order
- Variant: the affiliate link opens the Black Portronics Bubble Multimedia Wireless Keyboard. Confirm the colour and that the title says Bubble, not Bubble 2.0, 3.0 or Square, as these are different products.
- Battery type: look at the listing’s technical details to confirm which batteries it needs and whether they are included.
- USB receiver: make sure the 2.4 GHz receiver is in the box, and keep it safe, since it is small and easy to lose.
- Device ports: the receiver needs a USB-A port. On a USB-C-only laptop, use Bluetooth or a USB-C adapter.
- Warranty: Portronics lists a 12-month warranty. Keep your invoice for any claim through Portronics’ service support in India.
- Layout expectations: remember it is TKL with no number pad.
If the Bubble fits your setup, you can see the Black Portronics Bubble keyboard on Amazon.in and confirm the details in the listing.

Final thoughts
The Portronics Bubble is a simple, focused keyboard: compact, quiet and able to hop between three devices over Bluetooth 5.0 or a USB receiver. That makes it a practical companion for an iPad or Android tablet, or for anyone switching between a laptop and a phone at one desk. Its weak spots are the missing number pad, the lack of published battery and range figures, and an older Bluetooth version than Portronics’ newer Bubble models. If those do not matter to you, check the current price of the Portronics Bubble on Amazon.in.
