Four-Port Charging Station for Desk and Nightstand

The SQ1049 replaces the tangle of individual chargers on a desk or hotel nightstand with a single 4-port charging station. The PD port handles the primary device — a tablet at 14.5V/2A or a large smartphone at 5V/3.1A — while the three USB-A ports charge phones, earbuds, smartwatches, and other accessories simultaneously. According to consumer electronics surveys, the average US household has 6.4 connected devices per person, and over 80% of users charge 2+ devices in the same location nightly. The SQ1049 covers this multi-device charging demand from a single wall outlet.

The multi-region plug options (US, UK, EU, AU) make the SQ1049 particularly suitable for hotel and hospitality deployments. A single charging station model serves guests from any country, with the same internal electronics and certifications across all plug variants. Hotel chains deploying the SQ1049 report a measurable reduction in front-desk requests for charger loans — a common guest friction point that the SQ1049 eliminates.

High-Power Architecture for Simultaneous Charging

The SQ1049’s ~77W total power budget is sized for worst-case simultaneous charging across all four ports. The PD port operates on a dedicated converter rail delivering up to 29W at 14.5V, completely isolated from the USB-A power stage. The three USB-A ports share a 48W (9.6A at 5V) power rail with per-port over-current protection. When all three USB-A ports are loaded equally, each receives approximately 3.2A — well above the 2.4A maximum that most smartphones draw on USB-A.

This shared-rail architecture on the USB-A side is a deliberate engineering trade-off: it allows the SQ1049 to deliver high total power in a compact form factor. Independent per-port regulation on all four ports would require four separate converter stages, increasing the charger’s size and cost by approximately 40% without meaningful benefit for the target use case (nightstand/desk charging of phones and accessories).

Safety Protections and Thermal Design

At 77W in a wall-mount form factor, thermal management is the primary engineering challenge. The SQ1049 achieves ≥88% conversion efficiency, limiting internal heat generation to approximately 9.2W at full load. The housing design includes strategically placed ventilation slots and an internal thermal pad that transfers heat from the switching FETs to the housing surface for passive dissipation. Surface temperature stays below 70°C at sustained full load — within UL 62368-1 touch-temperature limits.

Per-port protection includes OVP, OCP, SCP, and OTP on all ports. The PD port includes additional protection during voltage transitions — when switching from 5V to 14.5V, output voltage is clamped to prevent overshoots that could damage the connected device’s input stage. Optional surge protection at 1KV–6KV is available for deployment in regions with unstable power infrastructure.

OEM Customization and Hospitality Market

The SQ1049 is Sunshine’s most popular PD charger for the hospitality and commercial market, where multi-device charging stations are deployed at scale in hotel rooms, airport lounges, coworking spaces, and conference centers. Customization includes housing color (Pantone/RAL), logo application, PD profile firmware configuration, and full private-label retail or commercial packaging.

Production across dual factories — Changzhou, China (est. 2001, 600+ workers) and Vinh Phuc, Vietnam (est. 2018, 1,000+ workers). The Vietnam facility provides China+1 sourcing for tariff optimization on US-bound shipments. MOQ 1,000 stock (any single plug region), 3,000 custom. Lead time 25–35 days. Mixed-plug-region orders ship on the same timeline.

Certifications and Compliance

Full certification suite: UL 62368-1 (US/Canada), FCC Part 15 Class B, CE (EU LVD + EMC), RoHS/REACH. Each regional plug variant carries its own safety certification mark. Complete compliance documentation package for OEM importers.

Frequently Asked Questions

Can the PD port charge a laptop?

The PD port delivers up to 29W at 14.5V — sufficient for some ultrabooks and Chromebooks but below the 45–65W required by most full-size laptops. For laptop-class PD, see our SQ1026 65W PD Charger.

Are the 3 USB-A ports independently regulated?

The USB-A ports share a 9.6A power rail with per-port over-current protection. Each port is individually fault-protected, but total USB-A current is shared — approximately 3.2A per port when all three are loaded equally, which exceeds the 2.4A max draw of most smartphones.

Can I order mixed plug regions on one PO?

Yes — specify quantities per plug region at order time. All variants ship on the same production timeline with no per-region setup charge.

What MOQ and lead time?

MOQ 1,000 stock (any plug region), 3,000 custom (PD profile, color, logo). Lead time 25–35 days. Samples 5–7 days.
