Your wholesale price drops as your annual volume scales — 1K pilot orders, 25K stocking programs, 500K+ annual contracts. Mixed-SKU pallets, in-stock SKUs ship in 4 weeks, custom retail packaging available on every tier.
When your customers want premium — 65W, 100W, and 240W gallium nitride chargers, 50% smaller than silicon. Multi-port, fast-charging, your spec, your brand.
Got a spec the catalog doesn't cover? We build custom chargers from 5W to 240W — your topology, your housing, your certifications. 6-8 week development cycle.
For your in-vehicle phone-charging accessories. 12V/24V mobile car chargers with built-in USB-C cable plus 2× USB-A. Custom branding for your retail or promotional program.
Your everyday workhorse — wall, laptop, multi-port. USB-C Power Delivery 3.0 chargers from 20W to 100W, UL 62368-1 listed, ready for your branded packaging.
If Section 301 is squeezing your margins, you need a supplier with both China and Vietnam production. We run identical QC and approved BOMs at both sites — so you can shift volume between countries based on your tariff math, without re-qualifying your bill of materials.
Your buyers expect telecom-grade quality. We've shipped under private label to AT&T, Verizon, T-Mobile, and DirecTV for 12+ years — with audited Tier-1 supplier status. Every shipment lands with full UL / FCC documentation, so your QC team has nothing to chase.
Submit your spec and you get a real reply — not a form letter. Our sales engineering team turns around your quote quickly, walks through your technical questions, and stays on your project from first inquiry through to delivered shipment.
You bring the spec. We build the topology, tool the housing, run EMI/EMC pre-compliance, and ship your first article in 6-8 weeks. Whether you need a 5W phone adapter, a 65W GaN multi-port, or a 240W USB-PD 3.1 desktop charger — your custom design is what we build every day.
Your customs broker shouldn't have to chase paperwork. Every shipment lands with the full packet — UL 62368-1 listings, FCC IDs, CE Declaration of Conformity, RoHS / REACH / Cal Prop 65 declarations, and DOE Level VI energy reports. Day one, ready to clear.
Your wholesale price drops as your annual volume scales. Quoted in tiers from 1,000-unit pilots to 500,000-unit annual programs.
Your logo, your colors, your packaging. We handle artwork prep, silkscreen tooling, and packaging-line setup — your customers see your brand, not ours.
Beyond branding: fully custom housing, PCB layout, plug configuration, and certification work. New SKU programs from a 5,000-unit MOQ.
20+ years building chargers. Dual-country production. Pre-certified for the markets you ship to. The OEM charger manufacturer your sourcing list has been missing.
You need a charger partner who flexes with your business — not just takes an order. Since 2003, we've manufactured 8+ million chargers a year for OEM brands, telecom carriers, and electronics distributors who needed someone reliable on the other end of the supply chain.
Whether you're piloting 5,000 units or scaling to 500,000 a year, our OEM program team handles your tooling, your certification, your packaging, and your direct-to-warehouse logistics. You tell us your spec — we build to it.
"We were burned by two trading companies before we found Sunshine. I flew to Changzhou, walked the SMT line, saw the UL test bench, and placed our first 30,000-unit USB-C PD order on the spot. Five years later we're at 200K annual under our brand. Real factory, real engineering, real export team."
EU Consumer Electronics Importer
"Sunshine quoted us a 20W USB-C wall charger at $4.20 landed at 50,000 units — 18% below our previous supplier, with retail-ready clamshell packaging in our brand colors. Mixed-SKU pallets meant we could blend GaN and standard PD on one order. Reorder hit in 60 days."
U.S. Electronics Wholesale Distributor
"Their engineering team flagged a thermal issue in our original 65W PD charger spec that we'd missed. Re-tooled the design, re-tested, shipped on time. That's the kind of partner you want building your branded products."
