What We Make

Seven Product Families From One Shenzhen Plant

Jonai Tech has built memory card readers in Shenzhen since 2007, and now builds the KIKOO range of magnetic wireless power banks, Qi2 chargers, GaN wall chargers and OTG adapters alongside them. Nineteen products, seven families, every one of them published here with the specification the factory actually quotes.

Products

Published With The Specification, Not With Adjectives

Every product below lists its real outputs, its model codes where the factory assigns them, and its certification list. Where the factory specification publishes nothing, the page says so. All nineteen products are on one page.

What Problem We Solve

The Wattage On The Box Is Not The Wattage On The Desk

Accessory buyers cannot compare suppliers when every product page is a paragraph of adjectives. The wattage that a charger reaches with two ports loaded, the certification list on a lithium pack, whether a magnetic pad is Qi2 certified or merely magnetic: those are the facts that decide an order, and they are usually the ones held back until after the enquiry.

What Usually Goes Wrong

  • A charger is listed at 65W and delivers 20W to each port once two devices are plugged in
  • A magnetic pack is described as Qi2 when it is only magnetic
  • Capacity is quoted in milliamp-hours, which is not the unit an airline uses
  • The certification list appears after the purchase order rather than before it

What We Publish Instead

  • Every published output figure, model code and certification list on this site is reproduced from the factory specification. Where the specification does not publish a figure, the page says so instead of filling the gap.
  • Port behaviour under real load, not just the headline figure
  • Certification lists reproduced exactly, including the marks a market needs
  • Watt-hour ratings on every lithium product, because that is what gets regulated

Questions

Frequently Asked Questions

Are you a factory or a trading company?
Jonai Tech has developed and produced memory card readers in Bao'an, Shenzhen since 2007. The KIKOO wireless charging range is produced in a factory of more than 3,800 square metres with about 100 employees, certified to ISO9001 and audited to BSCI.
Which of your magnetic products are actually Qi2 certified?
The 5000mAh magnetic power bank and the ultra-slim platform publish Qi2 certification. The 25W 10000mAh power bank and the 25W ultra-thin pad publish Qi2.2. Any product page that does not say certified does not claim it.
How many products do you make?
Nineteen, in seven families: magnetic power banks, magnetic wireless chargers, GaN wall chargers, cable-integrated power banks, USB 2.0 and USB 3.0 card readers and OTG adapters. All of them have a full page here.
Do you publish specifications before an enquiry?
Yes. Outputs, model codes, materials and certification lists are on every product page. Where the factory specification does not publish a figure, the page says so instead of estimating one.
Can we order under our own brand?
Yes. Most of what leaves this factory carries a customer's label. Colour, print, packing and, where the quantity justifies it, tooling are all open.
