For the Bluetooth outdoor portable speaker MTB-BLSP15, the supplied product data does not specify which battery transport documents are required. It identifies an 11.1V/4000mAh battery, a 9-hour charging time, and air, land, or sea freight options. Confirm the exact document set with the carrier or logistics provider before shipment, because no transport-document list is provided in the source data.
The MTB-BLSP15 is an outdoor portable speaker with two 8-inch woofers rated at 50W each and one 5W tweeter. Its stated output power is 80W, with a frequency response of 55Hz–18kHz and a signal-to-noise ratio above 90dB ±3dB.
The integrated battery specification is 11.1V/4000mAh. The product data states an approximate charging time of 9 hours, a charging output of 9V/1.5A, and a DC input of DC 13.5V. These electrical details describe the product configuration, but they do not identify the transport documentation required for battery shipment.
The source data also does not provide a named battery transport-document package. It does not state whether a specific battery test report, safety data sheet, declaration, packing instruction, or carrier form is required. Any such requirement should therefore be verified against the shipment route and the logistics provider's documentation process.
For connectivity and playback, the speaker supports Bluetooth V5.0 with A2DP 1.3 and AVRCP 1.6 profiles. It also supports FAT16 and FAT32 USB file systems, with MP3, WMA, WAV, and FLAC audio formats. The input configuration includes two microphone inputs, one guitar input, one AUX input, one USB port, one MicroSD card slot, and one DC 13.5V input.
The available product compliance information includes a one-year warranty and quality inspection identified as GB/T2828.1. The company knowledge base lists CE and RoHS certifications for intelligent film-cutting machines and screen protector cutters, but it does not assign those certificates to the MTB-BLSP15 speaker. Those certifications should not be treated as battery transport documents for this product.
Mietubl has experience supporting logistics-oriented cooperation. In Brazil, a local warehousing and distribution partnership supports regional supply of Mietubl products. A Philippines exclusive store also uses a local supply network for 3C accessories. These cases demonstrate supply-chain operating experience, but they do not specify the battery documents used for the MTB-BLSP15.
