PD Fast Charging + Standard USB in One Compact Charger

The SQ1044 addresses the most common multi-device charging scenario: a primary device that supports PD fast charging (smartphone, tablet) paired with a secondary device on standard 5V USB-A (wireless earbuds, fitness tracker, smartwatch). According to consumer electronics usage data, over 70% of multi-device charging sessions follow this exact pattern — one PD-capable device plus one legacy USB-A device. The SQ1044’s asymmetric port design matches this reality without the unnecessary cost of two PD ports.

The PD port negotiates between 5V/2.4A, 9V/2.15A, and 12V/1.5A based on the connected device’s power request through the USB-C CC pins. A smartphone requesting 9V for fast charging receives exactly that voltage within 200 milliseconds of connection, while the USB-A port simultaneously delivers 5V/2.1A to the secondary device. Both ports operate with independent voltage regulation and fault protection — a short circuit on one port does not affect the other.

The Entry Point for PD Multi-Port Charging

The SQ1044 is the most compact and cost-effective multi-port PD charger in Sunshine’s PD charger lineup. At approximately 28W total power, it fits in a standard wall-plug form factor without the bulk of higher-wattage charging stations. For applications needing more ports, the SQ1049 4-Port adds three more USB-A ports for desk/nightstand charging, and the SQ1053 combines PD with dual QC3.0 ports for mixed Apple/Android environments.

The 2-port design is the right choice for three specific use cases: product bundling (shipping a PD charger as an in-box accessory with a device that also includes a USB-A charging cable for a secondary accessory), hotel nightstand charging (where simplicity and compact size matter more than port count), and office desk spots where a single employee needs to charge their phone and one accessory.

Safety Protections and Power Architecture

The SQ1044 uses a dual-rail power architecture with independent regulation for each port. The PD port runs on a dedicated switching converter with its own transformer winding, enabling voltage transitions between 5V, 9V, and 12V without affecting the USB-A port’s stable 5V output. This isolation is critical during PD voltage negotiation — when the PD port switches from 5V to 9V, the USB-A port must maintain its 5V output within ±5% tolerance without any voltage excursion. Chargers with shared power rails often produce a brief voltage dip on the USB-A port during PD transitions, which can cause connected devices to disconnect and reconnect.

All protection circuits — OVP, OCP, SCP, and OTP — operate independently per port. The housing is UL94 V-0 flame rated, meeting the requirements of UL 62368-1 and IEC 62368-1. Optional surge protection at 1KV, 4KV, or 6KV is available for deployments in regions with unstable power grids.

OEM Customization and Private Label

The SQ1044’s PD voltage profile is fully customizable through firmware programming — Sunshine’s engineering team can configure any combination of PDOs within the 28W power budget at MOQ 3,000 with no tooling premium. An OEM whose device requires only 5V and 9V can eliminate the 12V PDO for a cleaner negotiation profile. A manufacturer needing 5V/15V instead of 5V/12V can substitute the PDO table in firmware — same hardware, different configuration.

Physical customization includes housing color (Pantone/RAL matching), logo pad printing or laser engraving, port accent colors for visual differentiation between PD and USB-A ports, and plug configuration (US or EU). Production across dual factories — Changzhou, China (est. 2001, 600+ workers) and Vinh Phuc, Vietnam (est. 2018, 1,000+ workers) with China+1 sourcing for tariff optimization. MOQ 1,000 stock, 3,000 custom. Lead time 25–35 days.

Certifications and Global Compliance

Full certification suite: UL 62368-1 (US/Canada), FCC Part 15 Class B (EMC), CE (EU LVD + EMC Directives), RoHS/REACH for restricted substance compliance. DoE Level VI efficiency certification available as an option. Complete compliance documentation package provided for OEM brand importers — test reports, certificates of conformity, and DoC templates.

Frequently Asked Questions

Does the PD port support USB-C to Lightning for iPhones?

Yes — iPhones 8 and later support PD fast charging at 9V via USB-C to Lightning cable. The SQ1044’s PD port provides 9V/2.15A, enabling fast charging at the maximum speed the iPhone hardware supports — approximately 50% charge in 30 minutes.

Can the PD voltage profile be customized?

Yes — custom PDO tables configurable via firmware at MOQ 3,000. Any voltage/current combination within the 28W power budget. Sample turnaround 5–7 working days for custom PD configurations.

How does this compare to the SQ1053 3-Port?

The SQ1044 has 1× PD + 1× USB-A (standard 5V). The SQ1053 has 1× PD + 2× QC3.0 — all three ports fast-charge capable. Choose SQ1044 for cost-optimized 2-port scenarios; SQ1053 when multiple devices need fast charging.

What MOQ and lead time?

MOQ 1,000 stock (US or EU plug), 3,000 custom (PD profile, color, logo). Lead time 25–35 days. Samples 3–5 days.
