USB Mini Humidifier 390ml Desk Mist

A USB-powered ultrasonic humidifier built for a desk, a bedside table or a small work area. Two bodies share the same internals: a squat one at 420 ml, 70 x 140 mm, and a vase one at 360 ml, 100 x 160 mm. The listing name quotes 390 ml for the series; tell us which body you need and we confirm its exact tank on the quotation. Rated mist output is 50 ml/h and the factory positions the model for rooms of 10 sqm or less. At that rate one fill runs about 8 hours; continuous mode switches itself off after 4 hours and interval mode after 6 hours. Fill from the top without taking the body apart. The single nozzle turns a full 360 degrees, so the mist can be pointed away from screens, paper and sockets. One press gives continuous mist, two presses give interval mist, and a long press turns on the mint night light together with interval mist. The factory rating is 36 dB or less, the level you can leave running on a desk during a call. Power comes in two builds. Build A is USB only: DC 5 V, 300 mA, 2 W, running from any 5 V USB source with no battery inside. Build B carries a rechargeable battery charged through the micro-USB port with the USB cable supplied. The spec sheet states DC 5 V / 300 mA while the photos show a charging cable, so the build for your order is to be confirmed with the factory: tell us which one you want and we bind it into the order. The factory has not fixed a colour box, a master carton or units per carton for this model, so packing is quoted per order and built to your specification. Body colour (white, pink, green), logo printing, colour box, manual language and packing can all be changed, and OEM and ODM are available. Every unit ships with an English manual; a manual in Arabic, Spanish or another language starts at 2,000 pcs per language, and we can send you the English, Arabic or Spanish manual as an e-file so you can print locally. Whether a wall adapter is bundled is confirmed with the factory per order. We are YIWU RUIHA TRADING CO.,LTD., a sourcing agent based in Yiwu, not the factory. The factory holds the certifications this model needs (CE and RoHS as applicable to your market) and we request the exact list and copies for your destination; certificate numbers are not listed here. We quote FOB Yiwu and work with the plant on your behalf. Version pricing: the USB-powered version is quoted at the price shown. The version with a built-in rechargeable battery is 1 USD more per unit and ships as a lithium-battery product, so UN38.3 and an MSDS are required before air freight. Tell us which version you want when you order.
