Import 300w Portable Solar Folding Charger Package — Buy in wholesale FOB from Supplier in China

This 300W portable solar folding charger package from Domy New Technology (shenzhen) Co., Ltd. uses monocrystalline silicon cells with a rated maximum power of 300W at standard operating conditions. The electrical parameters are precisely stated: 19.8V working voltage, 15.15A working current, 23.4V open-circuit voltage, and 15.67A short-circuit current. Two laminate variants are offered, PET or ETFE surface film, with the ETFE option specified for longer service life through improved UV and abrasion resistance. The ETFE variant employs imbricated lamination technology, a construction method that interlayers film and cell to enhance durability without the bulk of traditional framed glass modules.

The physical format is a folding mat rather than rigid panel: unfolding dimensions are 2940 x 595 x 3 mm, collapsing to 770 x 595 x 50 mm for transport. At 3mm thick unfolded, this is a true flexible or semi-flexible module designed for mobile, camping, or emergency power applications rather than permanent installation. The package ships in a 790 x 615 x 70 mm carton with net weight 12.5 kg and gross weight 13.5 kg. Output types are specified as A Type and B Type, though the source does not define the connector standard, whether that refers to DC barrel, Anderson Powerpole, MC4, or USB-PD configurations. The 19.8V working voltage sits below standard 24V nominal battery systems, suggesting direct charging of 12V lead-acid or lithium battery banks with appropriate controller, or DC-DC boost regulation for higher voltage applications.

Buyers for this product category include outdoor equipment distributors, emergency preparedness retailers, RV and marine outfitters, and military or disaster-relief procurement channels. The portability and foldability address users needing temporary, stowable power rather than fixed rooftop generation. For importers, the critical verification points are the output connector standard, whether an integrated charge controller is included, and the actual IP rating for outdoor use. The low profile and flexible construction raise questions about mechanical durability under repeated folding, bend radius limits, and cycle life testing. Confirm with Domy New Technology (shenzhen) Co., Ltd. whether the 300W rating is measured at STC or a different reference condition, as portable panels sometimes use non-standard rating points that inflate apparent performance.

Domy New Technology (shenzhen) Co., Ltd. is based at F3, Block 2, Yaochuan Industry Area, Yongfu Road, Fuhai Street, Baoan District, Shenzhen 518103, Guangdong, China. The location in Baoan District places it within Shenzhen's extensive electronics manufacturing corridor, with access to component supply chains for solar cells, flexible circuit substrates, and portable power management systems. The supplier holds a harbour trust tier on the platform, with a 0.00% response rate and zero recorded average hours, indicating no active communication through this channel. Buyers should not rely on platform messaging alone and should pursue direct contact via the provided address or independent sourcing verification.

The profile does not state manufacturing certifications, export experience, or company registration details such as capitalisation, employee count, or year of establishment. The product description contains technical specifications but lacks brand registration, patent information, or OEM/ODM service declarations common in Shenzhen supplier profiles. The dual output type offering (A Type and B Type) suggests the supplier may configure products for different regional markets or buyer specifications, but without clarification, this remains ambiguous. Importers should request the supplier's business licence, any ISO 9001 or ISO 14001 documentation, and proof of product safety testing such as CE, RoHS, or UL listings for electrical products.WlT.
