Merchandising the foldable panel
A foldable panel rarely sells alone for long. Programmes do best when the panel is merchandised with the banks and small devices it is bought for, with honest expectations on the box: these are top-up chargers, not wall-socket replacements — the output figure is a peak rating, and the day's yield is the honest number.
21W and 28W: the two classes
The classes divide by rated output. The 21W Solar 21 format is the smaller panel: it folds into a daypack and opens flat at a café table or a campsite. The 28W class is the larger panel, with the higher rated output. Send the kit list with the inquiry and the class is confirmed against it.
The line is built in foldable and flexible formats. Foldable rigid panels pack flat and open out at the campsite; flexible panels curve to a pack or a tent skin and weigh less. The format choice is about how the panel travels; the class choice is about the day's energy budget.
A charger that travels flat
Portability is this product's whole design brief, and it changes how it should be sold: merchandised open, not boxed — a panel displayed flat on a wall or counter explains itself in a way a specification table never will. The customer who has watched a phone charge from a folded sheet of panel understands the product, the price and the programme in one look.
For online programmes, the equivalent is the sequence photograph: folded, unfolding, open and charging. It is the rare product whose instruction manual is also its advertisement.
Stocking the foldable panel
Programmes do best when the panel is stocked in depth at both classes rather than thinly across many variants: the 21W for the travel shelf, the 28W for the camping shelf, one brand story across both. Branding options cover the retail packaging, and samples of both classes fit in a single courier bag — the fastest programme evaluation in this catalogue.
Choose your classes and formats, tell us branding and volumes, and the quotation will cover the combination as one programme.
What a day of sun actually gives
Set the expectation in devices and days, not watts alone: the class figure is a rated output, and what a day delivers depends on the sun the panel actually gets — bright, broken or short. Work the kit list against the class before the order: the devices, their batteries, and the hours of sun the trip realistically gets.
Print that framing on the box — devices per day of sun, honestly stated. It is a rare accessory whose honest description is also its best advertisement, and the discipline costs nothing but the decision to keep it.
Keep the framing in devices and days, and the specification table can stay where it belongs — on the product page, for the buyers who go looking for it.
Ordering the foldable charger
Choose your class (21W or 28W) and format (foldable or flexible), tell us branding and volumes, and we will quote.
State both choices in the inquiry — the class, 21W or 28W, and the format, foldable or flexible — together with the device list the panel is matched against, and the quotation is worked on that combination rather than on the class name alone.
