1. Mobility first
If the site changes weekly, a fixed outdoor vertical is the wrong spend. Portable units exist so one person can roll a high-bright screen to the entrance, aisle or outdoor bay.
PD-S is single-sided. PD-D is double-sided. Both sit under the portable hub and complement fixed OD-V installs.
2. Comparison
| Decision | PD-S | PD-D |
|---|---|---|
| Faces | One primary face | Two faces |
| Power planning | Single-face load | Higher load; resize the pack |
| Best fit | Queues, entrances, demos | Aisles and plazas with two-way traffic |
| Detail pages | PD-S | PD-D |
3. Runtime is a table, not a slogan
Runtime depends on battery pack capacity, brightness profile, content type and ambient temperature. Ask for the runtime table on the exact SKU.
Do not accept orphan capacity numbers that cannot explain shift-length operation. If the quote cannot show hours at a stated brightness, treat runtime as TBC.
4. RFQ checklist
Send shift length, target brightness, single vs dual face, charge access, whether pass-through AC is required, and any IP evidence you need for the portable housing.

Frequently Asked Questions
Does double-sided cut battery life in half?
Dual faces increase load. Exact hours depend on pack size and brightness. Request the dual-face runtime table for the quoted SKU.
How is PD-D different from WD-D?
PD-D is portable. WD-D is a fixed high-bright window display for glass storefronts.
Can I run the unit while charging?
Many portable designs support AC operation while charging. Confirm pass-through behavior on the quoted model.
Where is the portable hub?
Start at /products/portable-battery/ for the category overview, then open PD-S or PD-D.
