The 500\u20135,000 band is where mid-batch custom becomes economical. At 5,000\u201350,000, volume pricing kicks in. Above 50,000, a big OEM\u2019s scale usually wins. Paiyi Power opens custom projects from <strong>200 pcs<\/strong> and quotes from the bill of materials, so you can see exactly what moves the price instead of receiving a single opaque number.<\/p>\n<hr \/>\n<h2 style=\"border-bottom: 2px solid #1264a3; padding-bottom: 6px; margin-top: 36px;\" id=\"what-actually-makes-up-a-power-adapter-s-unit-cost\">What actually makes up a power adapter\u2019s unit cost<\/h2>\n<h3 style=\"margin-top: 24px; color: #2f6b4f;\">Bill of materials (BOM)<\/h3>\n<p>The components \u2014 transformer, GaN\/silicon switch, capacitors, enclosure, connector \u2014 are the largest recurring part of the power adapter cost. A transparent quote names these parts, not a vague \u201cstandard build.\u201d<\/p>\n<h3 style=\"margin-top: 24px; color: #2f6b4f;\">Tooling and NRE (one-time)<\/h3>\n<p>Custom enclosure, fixture, and test jig are one-time engineering costs. On a 200-pcs run they weigh heavily per unit; on a 5,000-pcs run they almost disappear. This is the main reason small batches look expensive.<\/p>\n<h3 style=\"margin-top: 24px; color: #2f6b4f;\">Labor and test<\/h3>\n<p>Hand assembly and 100% functional test cost per unit.

A 200-pcs custom run still needs a custom enclosure tool, a test fixture, and engineering time. Those do not shrink with quantity. Spread over 200 units they add real cost per piece; spread over 20,000 they vanish. The higher small-batch price is not a markup \u2014 it is the setup cost doing its job. The fix is not to accept a vague quote but to see the NRE listed separately.<\/p>\n<h2 style=\"border-bottom: 2px solid #1264a3; padding-bottom: 6px; margin-top: 36px;\" id=\"the-mid-batch-sweet-spot-500-5-000\">The mid-batch sweet spot (500\u20135,000)<\/h2>\n<p>This is where most SMB custom programs live, and where mid-batch power adapter cost is at its most favorable. The BOM dominates, the NRE is amortized enough to be painless, and you still get direct engineering for non-standard requests. If your annual volume sits here, optimizing the BOM \u2014 not chasing OEM-scale pricing you will not hit \u2014 is the real cost lever.<\/p>\n<h2 style=\"border-bottom: 2px solid #1264a3; padding-bottom: 6px; margin-top: 36px;\" id=\"where-volume-pricing-kicks-in-5-000-50-000\">Where volume pricing kicks in (5,000\u201350,000)<\/h2>\n<p>Above 5,000 pcs, component volume breaks and line efficiency start to cut the BOM, so the power adapter cost falls into volume territory. This band is contestable between a specialist factory and a big OEM; compare on unit cost, lead time, and how much customisation each will still accept. A factory often stays competitive here because its overhead is lower.<\/p>\n<h2 style=\"border-bottom: 2px solid #1264a3; padding-bottom: 6px; margin-top: 36px;\" id=\"beyond-50-000-when-a-big-oem-wins\">Beyond 50,000: when a big OEM wins<\/h2>\n<p>At six-figure annual volume, a big OEM\u2019s scale, component clout, and process maturity usually beat a small factory on unit price. The trade-off is MOQ, NRE sizing, and flexibility. If you are here with a standard product, the OEM is rational; if you are here with a non-standard spec, the factory may still win on the engineering.<\/p>\n<h2 style=\"border-bottom: 2px solid #1264a3; padding-bottom: 6px; margin-top: 36px;\" id=\"how-a-transparent-quote-should-break-down\">How a transparent quote should break down<\/h2>\n<table style=\"border-collapse: collapse; width: 100%; margin: 18px 0; font-size: 14px;\">\n<thead>\n<tr>\n<th style=\"background: #f5f7f8; border: 1px solid #d9dee3; padding: 9px 11px; text-align: left;\">Line item<\/th>\n<th style=\"background: #f5f7f8; border: 1px solid #d9dee3; padding: 9px 11px; text-align: left;\">What to check<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border: 1px solid #d9dee3; padding: 9px 11px;\"><strong>BOM (components)<\/strong><\/td>\n<td style=\"border: 1px solid #d9dee3; padding: 9px 11px;\">Named parts, not \u201cstandard build\u201d<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #d9dee3; padding: 9px 11px;\"><strong>Tooling \/ NRE<\/strong><\/td>\n<td style=\"border: 1px solid #d9dee3; padding: 9px 11px;\">One-time, shown separately or amortized<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #d9dee3; padding: 9px 11px;\"><strong>Labor &amp; test<\/strong><\/td>\n<td style=\"border: 1px solid #d9dee3; padding: 9px 11px;\">100% inspection stated<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #d9dee3; padding: 9px 11px;\"><strong>Compliance<\/strong><\/td>\n<td style=\"border: 1px solid #d9dee3; padding: 9px 11px;\">Cert cost per model, holder named<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 1px solid #d9dee3; padding: 9px 11px;\"><strong>Logistics<\/strong><\/td>\n<td style=\"border: 1px solid #d9dee3; padding: 9px 11px;\">Incoterms stated (EXW \/ FOB \/ CIF)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 style=\"border-bottom: 2px solid #1264a3; padding-bottom: 6px; margin-top: 36px;\" id=\"hidden-costs-a-trader-can-add\">Hidden costs a trader can add<\/h2>\n<p>A trader rarely shows you the factory\u2019s BOM. You see one number that bundles an unseen margin on top of a price you cannot audit. That is not fraud \u2014 it is how resellers earn \u2014 but for a custom program where spec and cost move together, invisible pricing means arguments later.

A specialist power adapter manufacturer like Paiyi Power opens custom projects from 200 pcs; large OEMs often start at 10,000+. Traders resell whatever their source factory sets.\"}},{\"@type\":\"Question\",\"name\":\"What is NRE and do I pay it every order?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"NRE is one-time engineering (tooling, fixtures, test setup). You pay it once for a new model; repeat orders of the same model do not recharge it. A transparent quote shows it separately.\"}},{\"@type\":\"Question\",\"name\":\"Why does a trader quote look cheaper than a factory?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"It may not be \u2014 you usually see one bundled number. A trader adds margin on a factory price you cannot audit. A factory BOM quote shows every line, so you compare like for like.\"}},{\"@type\":\"Question\",\"name\":\"Does GaN cost more than silicon?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The GaN switch costs more, but the smaller transformer and heatsink often offset it. At higher volumes the total is frequently comparable, with better efficiency and size as the payoff.\"}},{\"@type\":\"Question\",\"name\":\"How much does certification add to unit cost?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Certification is mostly a one-time per-model cost, not per unit. CE\/CB\/FCC and the underlying safety standard are charged when the model is certified; it does not recur on every piece you buy.\"}},{\"@type\":\"Question\",\"name\":\"Is 100% inspection worth the cost?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"For a compliance-sensitive market, yes. Testing every unit (ATE + burn-in + aging) prevents field failures that cost far more than the test. Paiyi Power inspects 100% of units.\"}},{\"@type\":\"Question\",\"name\":\"When should I move from a factory to a big OEM?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Around 50,000 pcs a year on a standard product. Below that, a specialist factory usually beats an OEM on MOQ, flexibility, and communication; above it, scale economy favors the OEM.\"}},{\"@type\":\"Question\",\"name\":\"Can I see the BOM before committing?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes \u2014 that is what a transparent power adapter cost quote is. A real power adapter manufacturer names the key components and the NRE up front; if a supplier refuses, that is a red flag.\"}}]}<\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Power Adapter Cost Transparency: Why 500, 5,000 and 50,000 Units Price Differently Published: September 2026 Reading time: 7 min Audience: OEM brands, buyers, and product teams budgeting custom power adapters and chargers at mid volume By Han \u2014 Paiyi Power, a power adapter manufacturer and OEM\/ODM factory that quotes custom projects from the bill of [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":1076,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[],"class_list":["post-580","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-services"],"_links":{"self":[{"href":"https:\/\/www.paiyipower.com\/pt\/wp-json\/wp\/v2\/posts\/580","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.paiyipower.com\/pt\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.paiyipower.com\/pt\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.paiyipower.com\/pt\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.paiyipower.com\/pt\/wp-json\/wp\/v2\/comments?post=580"}],"version-history":[{"count":8,"href":"https:\/\/www.paiyipower.com\/pt\/wp-json\/wp\/v2\/posts\/580\/revisions"}],"predecessor-version":[{"id":1279,"href":"https:\/\/www.paiyipower.com\/pt\/wp-json\/wp\/v2\/posts\/580\/revisions\/1279"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.paiyipower.com\/pt\/wp-json\/wp\/v2\/media\/1076"}],"wp:attachment":[{"href":"https:\/\/www.paiyipower.com\/pt\/wp-json\/wp\/v2\/media?parent=580"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.paiyipower.com\/pt\/wp-json\/wp\/v2\/categories?post=580"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.paiyipower.com\/pt\/wp-json\/wp\/v2\/tags?post=580"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
