1. Check mobility and handling
A mobile display is useful when positions change during the day. Confirm unit weight, centre of gravity, wheel locks, thresholds and the approved handling method. Do not assume one person can safely move it, or that a portable unit is automatically outdoor-rated.
Compare PD-S single-sided and PD-D double-sided portable displays. Fixed OD-V outdoor vertical signage belongs to a different installation workflow; verify the chosen model's exposure limits separately.
2. Compare single- and double-sided configurations
| Decision | PD-S | PD-D |
|---|---|---|
| Display faces | One primary face | Two faces |
| Power planning | One display face plus player and system loads | Two display faces; confirm the total load and battery pack |
| Typical audience | One-direction queues, entrances or demonstrations | Two-direction aisles or event circulation; exposure limits by model |
| Product detail | PD-S | PD-D |
3. Runtime: record the test conditions
Runtime depends on usable battery energy, screen brightness, number of faces, content, player and network load, temperature and battery condition. Request a repeatable test for the quoted unit, not a family-level hours claim.
As a planning estimate, runtime in hours is usable battery energy in Wh divided by average total load in W. Nominal pack capacity is not all usable energy, and conversion losses and cutoff settings matter. This estimate is not a runtime promise: confirm measured start-to-cutoff results with the agreed brightness and content.
4. Portable battery signage RFQ checklist
Send shift length, screen size, face count, target brightness, indoor or outdoor exposure, quantity and market. Ask for the quoted battery energy, measured runtime conditions, recharge time, permitted charging operation, transport documents and service plan. Keep unconfirmed values marked pending.
Start with the portable battery signage hub, then compare the exact PD-S or PD-D configuration. A category name or outdoor marketing photo does not establish a model's ingress, temperature or wind limits.
Frequently Asked Questions
Does double-sided signage halve battery runtime?
Not automatically. A second active panel generally adds load, but runtime depends on the usable battery energy and each face's settings. Compare measured runtime under matching brightness, content, temperature and cutoff conditions.
How is PD-D different from WD-D?
PD-D is a portable double-sided display category. WD-D is a window-facing double-sided installation category. Compare mounting, power and exposure requirements for the exact model rather than treating the categories as interchangeable.
Can I run the unit while charging?
Do not assume it can. Request written confirmation of permitted charging operation, charger requirements, ventilation and temperature limits for the final model. Follow its battery and operating instructions.
Where can I compare the portable models?
Use the portable battery signage category page, then open the PD-S single-sided or PD-D double-sided product page. Verify each model's installation and battery options independently.
Planning pop-up retail signage? Use the procurement toolkit and send TZD Display your shift and site requirements. Runtime, weather suitability, warranty, MOQ and delivery require a written configured quote.
Sample acceptance: make the runtime test reproducible
- Record model and pack revision, battery condition, starting charge, brightness on each face, playlist, network mode, temperature and cutoff event.
- Time playback and recharge separately. Test restart behaviour and low-battery warnings using the approved charging procedure.
- Approve the intended indoor, sheltered or exposed location in writing, including ingress limits, stability and handling precautions. IP alone does not establish wind stability.
