Who we are

A power-focused factory,
not a trading desk.

We build in one category and we build it deeply. Every product leaves our floor after in-house safety, thermal and cycle-life testing — then ships with the documentation your customs broker and your marketplace actually ask for.

In-house engineering

10 hardware and firmware engineers on staff, from PCB layout to certification.

One point of contact

A named account manager who answers in English within 24 hours, every time.

Why buyers stay

Built around your launch date.

Not around our production schedule. Here is what that looks like in practice.

Compliance handled in-house

CE, FCC, RoHS, UKCA and PSE filings run by our own compliance team — not outsourced, not billed back to you per certificate.

Real tooling ownership

Private molds at no extra charge above 3,000 pcs, and your tooling stays yours — we hold no rights over the design we build for you.

Packaging that ships clean

Retail-ready boxes, FBA labels, poly-bag and hang-tag formats. Dielines and artwork proofs included in the sampling round.

Logistics without surprises

FOB, CIF or DDP to your door. We handle consolidation, customs paperwork and Amazon FBA appointment booking.

How we work

From your spec to your pallet, in five steps.

A typical private-label project runs 35–45 days from confirmed artwork to shipped container.

Step 01
Brief & quote

Send the spec, target price and market. You get pricing, a compliance list and a realistic timeline within 24 hours.

Step 02
Sampling

Modified or fully custom samples in 10–15 days, with test reports and packaging dielines alongside.

Step 03
Certification

Safety and EMC testing against your destination market while the molds and artwork are finalized.

Step 04
Production & QC

100% functional test, 4-hour burn-in on a sampled batch, AQL 2.5 pre-shipment inspection with a photo report.

Step 05
Shipment

FOB Shenzhen or DDP to your warehouse, with all documents issued in your company name.

Quality & compliance

The boring part,
done properly.

Charging products fail quietly — a cold joint, a drifting thermistor, a cable that loses 5% of its conductor after 200 bends. Our test protocol is designed to catch all three before your customer does.

  • Hi-pot, earth continuity and leakage current on every unit
  • Thermal imaging under full load at 25°C and 40°C ambient
  • 10,000-cycle bend and 5,000-cycle insertion testing on cables
  • Battery cell traceability by lot, with UN38.3 reports on file

Client feedback

Brands that came back for the second order.

“We moved our 65W charger line here after two bad batches elsewhere. Three orders in, the defect rate is under 0.3% and the packaging arrives exactly as the proof looked.”

“They flagged a thermal issue on our 140W design before we did. That saved us a recall. The engineering conversation is the reason we stayed.”

“First order was 500 pieces to test the waters. We're now at 12,000 a quarter and they still answer in a day.”

Common questions

Before you send an enquiry.

Everything buyers ask us in the first email, answered up front.

Still have a question?
500 pieces per model for stock designs, 1,000–3,000 pieces for custom molds depending on the product. Mixed-color and mixed-plug configurations count toward the same MOQ, and trial orders under MOQ are possible with a small-lot surcharge.
Stock samples ship in 3–5 days at cost. Modified samples (logo, finish, packaging) take 10–15 days. Fully custom tooling takes 25–30 days. Sample charges are refunded against your first production order.
Yes. We hold CE, FCC, RoHS, REACH and UKCA reports for our standard platforms, and can arrange PSE (Japan), KC (Korea), RCM (Australia) and safety marks for other markets. Certification cost and lead time are quoted line by line, so you only pay for the markets you actually sell in.
Yes — silk-screen, laser etching, UV printing and custom color matching are all available. We provide packaging dielines, and our in-house designer can adapt your artwork or build a retail box from scratch. Artwork proofs are approved before mass production.
30% deposit with the balance against the pre-shipment inspection report. T/T, and Alibaba Trade Assurance if you prefer an escrow. We ship FOB Shenzhen / Yantian, CIF, or DDP to your warehouse or Amazon FBA — DDP is quoted with duties included, so there is nothing to pay on arrival.
12 months from shipment. Verified defect rates above 2% are replaced free in the next order, plus a credit for the freight. We also keep your production records for 24 months, so a claim can be traced back to the exact lot and test data.
