CNCOB is not a trading company. We are a vertically integrated manufacturer — from cell selection and mold fabrication through to automated assembly and packing. Every power bank you order ships from the same controlled production environment that serves top-10 global solar inverter brands.
R&D, mold design, injection molding, precision stamping, automated assembly — all under one roof. No subcontractors for critical processes.
Dual-certified quality management and information security. Our CNAS-certified internal lab runs 100% testing at the sampling, material, and functional stages.
Established in 2006, CNCOB has built a global distribution network trusted by distributors, EPCs, and retailers across five continents.
We invest 5% of annual revenue into research and development, keeping our charging technology at the forefront of PD 3.1 and wireless standards.
Custom branding, private-label packaging, unique color schemes, and full product co-development. Our design team works directly with your procurement team.
No middlemen, no inflated margins. Direct purchasing means you capture the full margin advantage that trading companies use to fund their overhead.
Third-party quality certification backed by our own certified lab. Thorough supplier qualification audits and eco-friendly production standards apply to every SKU.
Stable inventory management and predictable lead times — the same reliability that global solar inverter brands depend on for project-critical shipments.
CNCOB holds dual international certification: ISO 9001:2015 for quality management and ISO/IEC 27001 for information security. Our CNAS-certified internal testing lab validates every product at the sampling, material, and functional stages — not just at final inspection. This gives B2B buyers audit-ready documentation and zero surprises at customs.
Our engineering team has spent years optimizing the balance between cell quality, thermal management, and charging intelligence. The result is a family of products that sustains performance across thousands of charge cycles.
Genuine 140W Power Delivery 3.1 over USB-C — not 100W mislabeled. Verified with MacBook Pro, Dell XPS, and Surface Pro compatibility.
High-grade lithium-ion cells with tight capacity tolerances. Batch testing ensures rated capacity is delivered, not just advertised.
Battery Management System with over-charge, over-discharge, over-current, short-circuit, and temperature protection on every unit.
Real-time wattage input/output display, temperature monitoring, and remaining charge percentage — visible information for professional users.
Models engineered at 99.9Wh and 97Wh — specifically below the 100Wh IATA carry-on threshold — without sacrificing usable capacity.
Simultaneous input and output: recharge the power bank from a wall adapter while charging your laptop from the same unit. No switching required.
