    FAQ

    • What is the actual output capability of DS-37W’s USB ports?

      DS-37W has USB-A (QC 18W) and USB-C (PD 18W) interfaces, but its junction-box specification lists a maximum output of 18W. Therefore, do not add 18W + 18W and claim 36W simultaneous delivery. It is a 37W-rated panel with an 18W-rated USB power-conversion stage; validate simultaneous-load behaviour and supported charging profiles on the production sample.

    • Do the folding panels carry an established IP rating and warranty?

      ETFE surfaces are specified, but no verified IP rating or continuous-rain exposure claim is stated in these brochures. Do not represent them as fully waterproof; protect connectors and junction boxes from water ingress. The datasheets specify a 1-year product warranty for DS-37W, DS-100W and DS-200W; the full warranty terms and any Australian statutory obligations need to be addressed separately.

    • What distinguishes PT-B-13W from PT-B-30W beyond panel wattage?

      Both are specified as 30 L backpacks, but their construction differs. PT-B-13W weighs 1.26 kg, uses 1680D polyester/ABS with a 420D nylon lining and includes a TSA007-style lock. PT-B-30W weighs 1.6 kg, has three storage compartments and uses a 1680D polyester exterior with a 320D polyester lining. The 30W model has a dual-panel configuration, while a 15W single-panel variant is also shown.

    • Is the PT-B-30W backpack always a 30W version?

      No. The sheet differentiates a 15W single-panel arrangement from a 30W dual-panel arrangement. Quotes, samples, labels, product images and cartons should explicitly identify which assembly is being purchased. A customer specifying “PT-B-30W” should not be sent a single-panel sample without agreement.

    • What can be delivered through each backpack’s USB outputs?

      PT-B-13W lists USB-A and USB-C at 5V/2A (10W per port rating). PT-B-30W lists USB-A QC3.0 up to 22.5W and USB-C at 5V/3A (15W). These are interface ratings, not a promise that both ports can deliver their individual maxima together under sunlight. Total simultaneous output, protocol profiles and low-light restart performance require sample testing.

    • Can the backpacks charge devices after sunset?

      No integrated energy-storage battery is specified in either backpack datasheet. Their solar panels provide power when adequate light is available; an external power bank would be needed for stored-energy use. If a buyer requests a built-in battery version, battery capacity, transport classification, electrical tests, mass and price must all be re-evaluated.

    • Are the backpacks rainproof, theft-proof or airline-approved?

      The fabrics and a TSA007 lock (13W model only) are specified, but water-ingress ratings, anti-theft test performance and airline/security endorsements are not substantiated. Avoid “waterproof”, “theft-proof” or “airline-approved” claims without documented evidence. For channel listings, agree a precise claims-and-test matrix first.
