Frequently Asked Questions
Yes. Our interchangeable adapter platform is built around one universal adapter body that accepts four plug head types — EU (CEE 7/4), US (NEMA 1-15), UK (BS 1363), and AU (AS/NZS 3112). You maintain a single SKU and simply specify which plug heads are required per shipment. No separate tooling, no separate model numbers, and no new certification process for each region.
The platform holds CE, UL, FCC, CB, UKCA, GS, PSE, and KC certifications on the core adapter body. For OEM projects, these certifications are transferable in most cases with only a label-change declaration — meaning you do not need to restart the compliance testing process from scratch. Our compliance team provides full documentation support, including test reports ready for customs brokers and retail buyer audits.
Our standard MOQ for OEM interchangeable adapters is 500 pieces per order. For off-the-shelf configurations with standard plug heads and output specs, the MOQ is 1,000 pieces. If you are evaluating the platform before committing to volume, we offer pre-production samples — contact our team to arrange a sample request with your target spec.
Yes. The adapter body supports customisable output voltage (5V, 9V, 12V, 15V, 19V, 24V are standard options), output current up to 3.5A, and output connector type — including barrel jack (various tip configurations), USB-A, and USB-C. Housing colour, surface finish, and OEM label are all configurable. Our engineering team reviews your device spec and recommends the correct configuration before production is confirmed.
For standard configurations on our existing platform, lead time is typically 20–30 working days from order confirmation and deposit receipt. For configurations requiring new output specs or custom housing, allow 30–45 working days to include engineering review and pre-production sample approval. We provide a firm production schedule at the time of order confirmation and maintain proactive updates throughout the production cycle.
Absolutely. We strongly encourage sample evaluation before bulk commitment. Standard platform samples can be dispatched within 5–7 working days. For custom-spec samples, lead time is 15–20 working days depending on the extent of modification required. Sample units include the adapter body and your selected plug head types, fully assembled and ready for functional and compliance testing at your end.
Yes. The plug head attachment uses a double-latch locking mechanism that is tested to withstand plug insertion forces and vibration in line with IEC 62368-1 safety requirements. The locking interface is part of the certified adapter body design — meaning the plug security is included in, not separate from, the compliance scope. Tool-free field swaps are supported, but the lock cannot be accidentally released during normal operation. Each plug head carries its own regional certification mark (CE, UL, UKCA, SAA) independently.
