The Vega SmartOne S3 Beard Trimmer offers an impressive 160 minutes of runtime on a full 90-minute charge, allowing for multiple grooming sessions without needing frequent recharges, making it convenient for both home use and travel.
The trimmer features a 'Smart Memory Function' that remembers your last used speed setting, saving you the hassle of re-adjusting it every time you pick it up for grooming.
The inclusion of a USB Type-C charging port is a significant convenience, allowing users to charge the trimmer with the same cable used for many modern smartphones and other devices, enhancing portability and reducing the need for extra chargers.
The trimmer offers three distinct speed modes – Eco (light blue), Pro (green), and Max (dark blue) – allowing users to customize their grooming experience based on beard density and desired styling, from light touch-ups to more intensive trimming.
While the trimmer offers a decent trimming experience, it does not provide a complete zero cut, meaning users looking for a perfectly clean shave will need to use a separate razor.

The Vega SmartOne S3 VHTH-36 is a cordless beard trimmer built for daily grooming, with a 160-minute runtime and USB Type-C charging as its headline features. It earns an 88/100 Flash AI Score drawn from 21 verified reviews across 5 platforms, with particular strength in battery life (95), charging convenience (90), and waterproofing (90). Review sentiment consistently backs these scores, especially on battery performance holding up across multiple grooming sessions without needing a recharge.
The S3 runs on a lithium-ion battery that charges fully in 90 minutes via USB Type-C. A 5-minute quick charge provides 10 minutes of runtime for last-minute grooming. The IPX7 waterproof rating allows wet use and direct rinse cleaning under tap water. Vega specifies the titanium blades for skin-friendly cutting across all strokes. Two comb attachments give 40 length settings from 0.5mm to 20mm, covering a close trim to a fuller styled beard. Three speed modes let you match motor intensity to your beard type: Eco for light beard, Pro for stubble, and Max for heavy growth. The Smart Memory Function retains your last used speed setting, so you skip the manual cycling every session.
The S3 suits men who trim frequently and want one trimmer for home and travel. At 148 grams and 15.6 x 3.6 x 3.4 centimetres, it packs easily. The detachable head and IPX7 rating make post-trim cleanup fast. One honest limitation: the S3 does not deliver a complete zero cut. If you need a skin-level shave at any point in your routine, you will need a separate razor. Reviewer feedback confirms this as a standard characteristic of comb-based trimmers, so factor it into your kit before buying if a clean shave is part of your daily routine.
Available between ₹899 and ₹1,762 across 11 sellers, the S3 offers solid value for a trimmer with this combination of runtime, waterproofing, and charging flexibility. At the lower price point, it bundles features that many trimmers at similar prices do not offer together: USB-C charging, IPX7 protection, Smart Memory, and 40 length settings in one unit. Reviewer sentiment supports the battery and waterproofing claims most strongly, which are also the S3's highest-scored categories. Flash AI recommends the Vega SmartOne S3 for daily groomers who prioritise battery longevity and easy cleanup, with one clear caveat: pair it with a razor if zero-cut shaving is part of your routine.

You can use the SmartOne S3 daily. Select your speed mode based on beard density: Eco for light beard, Pro for stubble, and Max for heavy growth. Attach one of the two comb attachments for your target length across the 40 settings from 0.5mm to 20mm. The Smart Memory Function saves your last speed setting, so your preferred mode is ready at the start of each session.
The S3 accommodates a range of beard types through its three speed modes. The Max setting targets heavy or dense beards, while Eco handles fine or light growth. With 40 length settings spanning 0.5mm to 20mm and titanium blades, it covers most beard lengths and textures. Users with very coarse beards can start with the Max speed setting for more efficient trimming.
Titanium is harder and more corrosion-resistant than standard stainless steel, which helps blades stay sharper over time and resist oxidation from regular washing. Vega specifies the titanium blades in the SmartOne S3 for a skin-friendly trimming experience. This matters for daily users who rinse the trimmer frequently, a routine the IPX7 waterproof rating fully supports.
The Smart Memory Function works from the very first use: it records your last speed mode and defaults to it the next time you switch the trimmer on. This eliminates the need to manually cycle through settings at the start of each session. Reviewer feedback notes consistent performance across multiple weeks of daily use, particularly on battery life matching the 160-minute specification.
The SmartOne S3 does not provide a complete zero cut. Reviewer feedback confirms that while the trimmer performs effectively across its 40 length settings, a fully skin-close shave requires a separate razor. This is a standard characteristic of comb-based trimmers and not specific to this model, so plan accordingly if a zero cut is part of your daily routine.
The SmartOne S3 is fully cordless with 160 minutes of battery runtime, removing the constraint of cable length or proximity to a power socket. It adds USB Type-C charging compatible with most phone chargers, an IPX7 waterproof rating for wet use and rinse cleaning, and a Smart Memory Function that a basic trimmer does not offer. Basic corded trimmers typically lack waterproofing, flexible charging, and any form of speed memory.
The Vega SmartOne S3 VHTH-36 is available from ₹899 across 11 sellers on Indian retail platforms. The price goes up to ₹1,762 depending on the seller and platform. Comparing prices across multiple platforms before purchase gives you the best chance of buying at or near the ₹899 price point.
The trimmer weighs 148 grams and measures 15.6 x 3.6 x 3.4 centimetres, putting it in a compact, travel-friendly form factor. The lightweight build reduces hand fatigue during longer sessions within the 160-minute runtime. The IPX7 rating also supports wet use, which many groomers find more comfortable on skin than dry trimming.
Vega specifies the titanium blades as designed for a skin-friendly trimming experience. Titanium is non-reactive and corrosion-resistant, which reduces the risk of irritation from repeated skin contact and frequent washing. Using the Eco speed mode on more sensitive areas such as the neck or jawline gives a gentler pass while staying within the trimmer's rated specifications.
AI SmartTrim technology in the S3 centres on the Smart Memory Function, which records the last speed mode you used and applies it automatically the next time you switch the trimmer on. The three speed modes are Eco, Pro, and Max. This function eliminates manual mode selection at the start of each session, which is particularly useful for daily groomers who consistently use the same setting.
