The catalogue

Minimum orders at Shenzhen Sunning Tension run from 20 pieces to 3,000 pieces depending on the model, and 326 of the 363 listings — 90% — are 200 pieces or fewer. The most common minimum is 100 pieces. If you are ordering a model that is already tooled, the low end of that range is genuinely available to you; the higher minimums belong to models with an expensive shell. A new mould of your own carries its own minimum: 500 pieces in PVC, 3,000 in metal, 5,000 in ABS.

Yes, and on a model that is already tooled it carries no tooling cost — Shenzhen Sunning Tension prints logos in one colour or full colour, and artwork setup is free. Minimum order for logo work starts at a few dozen pieces. Metal shells can be laser-etched instead of printed. Send vector artwork rather than a photograph of a business card and the first sample is right the first time.

Production lead times at Shenzhen Sunning Tension run from 5 to 30 working days, and 206 of the 363 listings quote 5 to 15. Rated capacity is 50,000 to 450,000 pieces per month depending on the model, so quantity moves the date less than most buyers expect. Add tooling time on top if you are cutting a new mould — about 5 working days for PVC, 12 for metal, 15 for ABS — and add your own approval time for the first article, which is usually the longest step nobody plans for.

Yes — Shenzhen Sunning Tension holds FCC, CE and RoHS documentation for the markets it ships to, held per model rather than as a company-wide badge. Name the model and the market and the file itself is emailed to you. You will not find a certificate number or a scanned certificate on this website, and that is deliberate: a certificate published as a picture proves nothing, and one quoted against the wrong configuration is worse than none. Anything with a lithium cell also has UN38.3 and an MSDS for your freight forwarder.

Shenzhen Sunning Tension accepts T/T bank transfer and Western Union on every model, and L/C on some orders — ask when you request the quotation. The deposit split is stated on your proforma invoice before you commit to anything. Our bank details are never published on this website and never sent from a free email address: if you receive payment instructions that do not come from lyn@sunntc.com, telephone +86 755 2907 4277 before you send anything.

Every price published by Shenzhen Sunning Tension is ex-works Shenzhen: it covers the goods, not freight, duty or insurance. Tell Miss Lyn the destination port and the term you work on and it is quoted that way instead. Your own forwarder can collect from the factory in Bao'an District, Shenzhen. One thing to raise early: the power-bank models contain lithium cells and travel as dangerous goods, so ask for the UN38.3 test summary and the MSDS with the quotation rather than the week the container books.

No. Shenzhen Sunning Tension publishes no customer's name, artwork or drawings, and every model in this catalogue is shown de-branded for exactly that reason. Send an NDA with your first email and it is signed before we quote. Drawings and artwork go to Miss Lyn and to the engineer who prices them; they are not shown to another customer and not used to develop a product of our own — we have no brand of our own to develop one for, and we never will be on the shelf beside you.
