Does Kestner sell to US buyers?
“Yes. Kestner builds power and connectivity hardware on its own lines in China and Vietnam and sells it through a US company — you buy from an American company and reach a person who prices and owns the outcome.”
Kestner Supply
“A US company that manufactures power and connectivity hardware on its own lines in China and Vietnam — power adapters, chargers, and cable assemblies, custom-built to spec, with a China-plus-one origin choice.”
Questions & answers
Can you build to our spec or private-label?
“Yes. Standard SKUs or fully custom — power supplies and cable assemblies to your drawing, with your brand on the housing and your artwork on the carton.”
Where are your products made?
“On our own lines in Vietnam and China, under one engineering system and test procedure. You choose the country of origin.”
Do you provide samples?
“Yes. We provide samples for approval before a production run, and buyers can audit either line by appointment.”
What certifications do your products carry?
“UL 62368-1 and DoE Level VI on power, USB-IF and UL AWM on cable, plus FCC, RoHS, and regional marks — each verifiable by file number.”
Are you a cable assembly manufacturer, or a distributor?
“We're the manufacturer. We build USB-C, USB, Ethernet, HDMI, coax, fiber, AV, and power cables — plus custom cable assemblies — on our own lines in China and Vietnam: cut, stripped, terminated, overmolded, and 100% continuity-tested. Bulk cable and finished assemblies alike.”
Can you make custom cable assemblies to our drawing?
“Yes. We build custom cable assemblies to your drawing or sample — cut, strip, terminate, overmold, and 100% continuity-tested, with your part number and artwork on the carton.”
Do you overmold custom connectors?
“Yes. We produce overmolded cable assemblies with custom strain-relief boots and connector housings, from USB and DC barrel to circular (M12) and connector-to-connector builds.”
Are your USB-C cables USB-IF certified and e-marked?
“Yes. USB-C cables are built to USB-IF spec with e-marker chips on assemblies rated 100 W and above, and UL AWM 2725 jacket ratings.”
Do you supply bulk cable?
“Yes. Bulk Ethernet (Cat5e/6/6a), coax (RG6/RG59/RG11), and other cable on the spool or box, alongside finished assemblies.”
Are you a power adapter and power supply manufacturer, or a distributor?
“We're the manufacturer. We build AC/DC power adapters, chargers, and switching power supplies on our own lines in China and Vietnam — standard SKUs and custom OEM builds — and back them with a US company. When a build needs a part we don't make ourselves, we source it to the same standard.”
Can you build a custom power supply to our spec?
“Yes. We build custom and OEM switching power supplies — AC/DC adapters, USB-C PD, and desktop or wall-mount units — to your voltage, connector, enclosure, and certification, under the same UL file as our standard lines.”
Can you match or replace an existing power adapter?
“Yes. Send the specs or a sample and we cross-reference an equivalent with the same output, connector, and safety marks for a drop-in replacement.”
Do you make USB-C PD and GaN chargers?
“Yes. GaN chargers from 30 to 140 W with USB PD 3.1, single and multi-port, plus fixed-output USB-C power adapters — standard or white-label to your housing and packaging.”
What is the total tariff on a power adapter imported from China?
“As of July 24, 2026, a switching power adapter of Chinese origin under HTS 8504.40.85 pays an effective 37.5%: a 0% MFN base rate, 25% Section 301 (List 3), and a 12.5% Section 301 forced-labor duty.”
Do the tariff layers add or compound?
“They add. Each layer is ad valorem on the same entered (customs) value, not compounded on the prior layer.”
Why do USB-C and HDMI cables pay more duty than power adapters?
“Because since 6 April 2026 they are articles of copper. HTS 8544.42.10, 8544.42.20, 8544.42.90 and 8544.49.10 are listed in HTSUS U.S. note 16(c)(viii), so a connectorized cable carries a 25% Section 232 copper duty on its full customs value under heading 9903.82.09 — from every origin, USMCA-originating Mexico included.”
What AV and audio cables do you make?
“Analog RCA, 3.5 mm (TRS and TRRS), and composite or component video cables — standard types or built to your drawing.”
Are they shielded for clean audio and video?
“Yes — shielded conductors reduce interference on analog runs; we match the shield and gauge to your length.”
Can you build custom connector combinations?
“Yes — RCA-to-3.5 mm, dual-RCA, and custom breakouts, with the connector, length, and jacket you specify.”
What certifications do they carry?
“UL AWM wire ratings and RoHS; file numbers on request.”
Custom lengths, jackets, and branding?
“Yes — length, jacket, connector, and logo to spec, with origin documented per unit.”
