About Us

VENQOE — Waterproof Connector Manufacturing Engineers Trust

Venqoe specializes in engineering and supplying waterproof connectors, junction boxes, and cable sealing solutions for lighting, solar, energy storage, agriculture, marine and industrial applications.

Who We Are

VENQOE is an ISO 9001 certified manufacturer specializing in waterproof and industrial connectors, based in Shenzhen, China. We design, produce, and test IP68 waterproof connectors, MC4/PV4 solar connectors, and LP-series quick-lock connectors for OEM brands, EPC contractors, and industrial buyers across 30+ countries.

We focus on one category — connection and sealing solutions — with in-house production and testing capability built around international IP rating, sealing, and durability standards. For engineers who can’t afford a connector failure in the field, VENQOE is built to be the manufacturer they don’t have to double-check.

Our Story

VENQOE was founded in 2016 by a team with deep roots in the connector manufacturing industry, built on a simple premise: engineers shouldn’t have to choose between fast delivery, competitive pricing, and connectors that actually survive in the field.

In the years since, we’ve grown from a specialist workshop into a full-scale manufacturer — building in-house tooling, molding, assembly, and testing capability under one roof, so quality control never depends on a third party. Every waterproof connector, every MC4 solar connector, every LP-series lock connector that carries the VENQOE name is designed, produced, and tested by our own engineering and production teams.

Today, VENQOE manufactures for lighting brands, solar EPC contractors, energy storage integrators, and industrial equipment makers in 30+ countries — companies that need one thing above all: a connector that performs the same way on day 1,000 as it did on day one.

We’re not trying to be a catalog of everything. We build waterproof and industrial connectors, and we build them to a standard that lets our clients stop worrying about the one component that’s easy to overlook — until it fails.

Our Manufacturing & Testing Capability

Every VENQOE connector is manufactured and tested in-house, under a documented quality control process that follows ISO 9001 requirements (+ IATF 16949?. Before any product leaves our facility, it passes through:

Automatic Insertion and Extraction Tester

Temperature rise current tester

Voltage Tester

Horizontal plug-in test

DC Resistance + Insulation Resistance Tester

IP68 Waterproof Teste

Scorch Wire Tester

Leakage Trace Tester

Horizontal Vertical Flame Tester

Constant temperature and humidity tester

The Video

This is the same process behind every product line we manufacture — from screw-free waterproof connectors to MC4/PV4 solar connectors to energy storage connectors — because a connector is only as reliable as the weakest step in how it was built and tested.

IP68 Waterproof Test Chamber

Verifies sealing performance under simulated rain, dust, and full immersion conditions

Salt Spray Test Chamber

Validates corrosion resistance for outdoor, coastal, and marine-grade applications

Insertion & Extraction Cycle Testing

Confirms mechanical durability over thousands of mating cycles

High/Low Temperature Chamber

Tests performance from -40°C to 105°C for extreme climate reliability

100% Continuity & Electrical Testing

Every batch checked before packing, not spot-sampled

UV Weathering Test

Validates long-term outdoor exposure resistance for solar and lighting applications
