For bulk buyers seeking eco-friendly alternatives to outdoor Bluetooth speakers, the available option is the Mietubl Outdoor Portable Speaker MTB-BLSP16, which supports Bluetooth, USB, TF, AUX, RGB, and DSP functions. The supplied data confirms rechargeable battery operation, durable outdoor use scenarios, and a one-year warranty, but it does not state recycled materials, energy-efficiency ratings, or environmental certifications.
The MTB-BLSP16 combines Bluetooth, RGB lighting, USB, TF, AUX, and DSP functions in one outdoor portable speaker. Its audio configuration uses two 66 mm speakers rated at 3 ohms and 30W each. Bluetooth 5.3 provides a stated transmission distance of 10 meters.
The speaker uses an 18650 battery rated at 3600mA, with a protection board and a 7.4V configuration. Playback time is specified as three hours at 80% volume. The available data describes rechargeable battery operation, but it does not provide lifecycle, charging-efficiency, recycled-content, repairability, packaging, or end-of-life information. Buyers evaluating environmental performance should request those specifications before making an eco-friendly product claim.
For outdoor applications, the supplied scenarios include backyard and garden parties, where the speaker provides ambient music for family barbecues and gatherings, and camping and hiking, where its portable format and stated battery runtime support use during trails and campsites. The data also describes IPX7 waterproof and dustproof protection for beach and poolside use.
The product information lists GB/T2828.1 as the quality inspection standard and provides one-year warranty support. A RED certificate is listed for a wireless Bluetooth speaker under certificate number HX240417001RED-MTB. The certification data supports the wireless product credential but does not establish environmental performance.
Mietubl has documented cooperation experience in Brazil, where a local joint venture operates warehousing and distribution for mobile accessories and intelligent screen protector cutting machines, and in the Philippines, where an exclusive store supplies 3C accessories and offers on-site film cutting. These cases indicate experience with regional distribution and offline retail operations relevant to bulk buyers.
