Sourcing AC/DC power adapters for your routers, IP cameras, networking gear, IoT gateways, or medical devices? You need a manufacturer who builds to your voltage, your plug, your certifications — and ships from a tariff-hedged production base. 20+ years building power adapters in China and Vietnam for U.S. equipment OEMs, telecom carriers, and service-depot replacement programs.
12W–100W Type-C output with USB-PD 3.0 negotiation — for your equipment ship-with kits or modern device bundles.
12V–48V desktop AC/DC up to 6.25A with detachable DC cords — sized for your switches, NVRs, IP-PBX systems, and laptop OEM programs.
Switching-mode AC/DC for your embedded equipment, industrial control panels, and OEM enclosures — built to integrate inside your housing, not just plug into the wall.
5V–15V plug-in AC/DC for your IP cameras, IoT gateways, LED drivers, and security panels — interchangeable US/EU/UK/AU heads.
POE injectors (802.3af / at / bt) for your IP-camera and AP networks, RF-filtered DC for TV-antenna headends, IEC 60601-1 medical-grade, and MagSafe-style replacements — your specialty spec, our day job.
You bring the spec; we build the topology. Custom voltage rail (5V–56V), current (0.5A–6.25A), housing, plug, and cert path — engineered with our in-house EMI/EMC lab, first article in 6–8 weeks.
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 your power adapter volume between countries based on your tariff math, without re-qualifying your bill of materials.
Your power adapter never gets unplugged. It runs your IP camera, your gateway, your switch — 24 hours a day, year after year, in attics and ceiling boxes and wiring closets. We design for that life: 1KV/4KV/6KV surge protection, input under-voltage cutoff, low no-load consumption, and component derating that holds spec across 5+ years of field service. Tested at the AT&T, Verizon, and DirecTV supplier-audit bar.
Submit your power adapter 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 5V wall-mount for consumer electronics, a 56V POE injector for your network rack, an RF-filtered DC supply for TV antennas, or a medical-grade adapter — your custom design is what we build every day.
Your customs broker shouldn't have to chase paperwork. Every power adapter shipment lands with the full packet — UL 62368-1 listings, FCC Part 15 IDs, CE LVD Declaration of Conformity, RoHS / REACH / Cal Prop 65 declarations, and DOE Level VI energy reports. Day one, ready to clear.
Whether you're stocking replacement adapters for your service depot fleet, bundling power supplies with the equipment you ship, or launching your own private-label catalog — here's how our pricing, branding, and custom tooling scale with you. Three ways we structure your program: wholesale, branded, or fully custom.
Replacement-adapter stock for your service depot — 12V, 24V, 48V, US/EU/UK plug variants, on the shelf when your truck rolls. Pricing tiers from 1,000-unit pilots to 500,000-unit annual programs.
Your logo, your colors, your packaging. We handle artwork prep, silkscreen tooling, label-line setup — your customers see your brand on the adapter that ships with their equipment, not ours.
Beyond branding: fully custom voltage rail, current capacity, housing, plug configuration, surge spec, and certification work. New SKU programs from a 5,000-unit MOQ.
20+ years winding transformers. Dual-country production. DOE Level VI across the catalog. The OEM power adapter manufacturer your equipment program has been missing.
You need a power adapter partner who survives certification audits, holds spec across volume, and ships when your equipment program ships. Since 2003, we've supplied millions of AC/DC adapters a year to U.S. networking-equipment makers, telecom carriers, IP-camera distributors, medical-device brands, and the service-depot operators who keep their gear running in the field.
Whether you're piloting a 5,000-unit pilot or scaling to a 500,000-unit annual program, our OEM program team owns your tooling, your UL/DOE filings, your branded packaging, and your direct-to-warehouse logistics. You tell us your voltage rail, your plug, and your cert path — we build to it.
"We needed 30,000 56V POE injectors shipped under our private label in 75 days for a network rollout. Sunshine delivered on time, fully UL 62368-1 and DOE Level VI certified, with our branding silkscreen on every unit. They're our go-to power adapter manufacturer now."
U.S. Networking Equipment OEM
"We needed 12V replacement adapters in three plug variants — US/EU/UK — for our service-depot fleet, 200K-unit annual pull. Sunshine held spec across the entire program with zero RMA escalations and ran the full UL listing under our brand. Best replacement-stock decision we made."
Telecom Equipment Lifecycle Operator
"Their engineering team flagged a thermal de-rating issue in our original 48W DC adapter spec that we'd missed. Re-tooled the design, re-tested for IEC 60601-1, shipped on time. That's the kind of partner you want building your branded products."
Medical Device Brand
Common questions from B2B power adapter buyers like you — about certification, customization, MOQs, and our China + Vietnam production options. Don't see your question? Ask us directly.
Yes. Every adapter in our standard catalog is built to DOE Level VI energy-efficiency standards and EU EcoDesign Tier 2 (no-load and active-mode efficiency targets). We hold UL 62368-1 listings under file number E-prefixed records, FCC Part 15 Class B IDs, and CE LVD Declarations of Conformity. Full energy reports, listing letters, and DoC packets ship with every order, so your retail compliance team and customs broker have what they need on day one.
Yes. Our engineering team customizes the full envelope — output rail (5V to 56V), current capacity (0.5A to 6.25A), plug head (US/EU/UK/AU interchangeable or fixed), surge tolerance (1KV / 4KV / 6KV per IEC 61000-4-5), regulation tolerance, no-load consumption, and housing form factor. First-article cycle is 6-8 weeks once spec is locked. Send your input/output spec and we'll respond with a buildable parts list.
Yes. POE: we manufacture single-port and rack-density POE injectors at 56V meeting 802.3af (15.4W), 802.3at (30W), and 802.3bt (60W/90W) — used in IP-camera installs, network closets, and AP rollouts. Medical: we run a separate IEC 60601-1 (3rd edition) compliant production line with Means of Patient Protection insulation and 2 × MOPP creepage clearances. Both lines carry full traceability to component lot.
Replacement-adapter programs (12V / 24V / 48V wall-mount and desktop with US/EU/UK/AU plugs) start at 1,000-unit MOQ for branded stock and 5,000 units for new SKU tooling. Pricing tiers step at 1K / 5K / 25K / 100K / 500K annual volume. Service-depot and lifecycle operators typically buy at the 25K-100K tier — talk to our OEM program team for your tier and lead-time arrangement.
Send us your input range (typically 100-240VAC), output rail and current, plug requirements, target market (U.S. / EU / global), certifications needed, and target volume. Our engineering-led quoting team responds with a buildable spec, a compliance plan, locked tier pricing, and an estimated first-article date. The faster you give us your spec sheet, the faster we close the quote.
Yes. Our catalog SQ1011 is a detachable-DC variant for through-wall installations (you stock the adapter, cut the cord to length on site). Our SQ1025 / SQ1026 / SQ1052 series ships with interchangeable US/EU/UK/AU plug heads — one SKU, one part number, one inventory line, deployable across global markets. Many of our equipment-OEM customers consolidate 4 regional SKUs into 1 with this approach.
Tell us your input voltage, output voltage and current, plug type, certifications needed, and target volume. Our sales engineering team will send you pricing tiers, spec sheets, and lead times — usually within a business day.
Three steps from your inquiry to your delivered power adapters. Most OEM programs ship within 90 days of spec lock.
