OTBK Portable Facial & Eye Mist Sprayer — 15ml Removable Tank, USB-C Rechargeable, Whisper-Quiet

OTBK Portable MultiUse Mist Sprayer is a USB-C rechargeable, ultra-fine facial and eye mister with a detachable 15ml tank for quick hydration and personal humidifying on the go.

Compact and lightweight, this mist sprayer is built to refresh tired eyes, revive dry facial skin, and add a gentle humidifying boost to your personal space. It runs quietly under 40dB, uses a removable nozzle and tank for easy cleaning, and offers up to 60 minutes of cordless use per charge. Designed for convenience, the sprayer is small enough for a purse or carry-on and simple enough for daily touch-ups at your desk, in transit, or at bedtime.

How does the OTBK mist sprayer soothe screen-fatigued eyes?

The device emits an ultra-fine, evenly distributed mist aimed at the delicate eye area to provide a cooling, hydrating sensation without dragging or saturating the skin. Because it operates quietly, you can use it discreetly during work or travel. It is intended for external use only and should not be sprayed directly into the eyes.

• Ultra-fine precision nozzle for gentle coverage
• Whisper-quiet operation under 40dB for discreet use
• Compact form fits in a bag for on-demand refreshment
• Auto shut-off after 10 minutes for safe short bursts

Can I use this sprayer for face hydration or over makeup?

Yes — the OTBK sprayer delivers a light, even mist suitable for boosting skin moisture before makeup or adding a dewy finish over makeup. Because the mist is very fine, it helps avoid disturbing cosmetics when used sparingly. Always use clean, water-based liquids and avoid oils or viscous formulas that can clog the nozzle.

• Fine-mist output for smooth, non-greasy hydration
• 15ml removable tank for quick refills and controlled amounts
• Nozzle can be removed for straightforward cleaning
• Lightweight 80g body for comfortable, on-the-go use

How practical is the detachable tank and how do I keep it hygienic?

The 15ml tank detaches in seconds so you can refill at any sink or bottle and rinse it under running water. Removability also allows swapping in a fresh tank or replacing it periodically for hygiene and optimal misting performance. The slope-designed inlet/outlet reduces residue buildup, and replacements are available when needed.

• Quick-release tank for effortless refills
• Removable spray head and nozzle for cleaning access
• Design minimizes residue and makes rinsing simple
• Replacement tanks and nozzles available separately

How long does the battery last and where can I charge it?

A full charge provides about 60 minutes of continuous misting and the included USB-C cable lets you recharge from a laptop, power bank, or car USB adapter. The device’s auto shut-off at ten minutes extends practical battery life for repeat short sessions. Its lightweight construction and cordless runtime make it a travel-friendly hydration tool.

• USB-C rechargeable with cable included
• Approximately 60 minutes cordless operation per full charge
• 10-minute automatic shut-off for safety and efficiency
• Small 80g footprint for easy travel and daily carry

Who is this for? The OTBK Portable MultiUse Mist Sprayer is aimed at commuters, frequent flyers, office workers, beauty enthusiasts, and anyone who wants quick, no-fuss facial or eye hydration. It’s useful for people who wear makeup and need a light refresher, professionals who want a discreet desktop humidifier, and travelers who need a compact, rechargeable solution for dry environments. Not suitable for internal use — use only with clean, water-based liquids and follow the included user manual for safe operation.
