About Fenjun New Energy

We are a Shenzhen-based power bank factory that builds charging products for brands, importers and Amazon sellers — from the shell and PCBA to the final tested unit.

Two dates, one story

We are often asked about the year in the header of this page, so here it is plainly: our current company was registered in 2015. The team behind it has been manufacturing power banks for more than 15 years. The earlier years were run through our predecessor operating companies, which is why our engineering team, our tooling and our cell suppliers go back further than the registration date.

What that means for you is simple — the process is mature, the people who will run your project have done it many times, and the company you sign the contract with is a stable, auditable entity.

What we manufacture

Power banks are our core business, and they cover most of what a brand needs:

• Magnetic wireless power banks, MagSafe-compatible, 5,000–10,000 mAh, 15W–35W

• Qi2 wireless power banks with TFT colour display

• Power banks with built-in USB-C or Lightning cables, tail-plug design

• Mini pocket power banks, 5,000 mAh

• Quick-charge power banks, PD 22.5W to 65W

• 3-in-1 magnetic chargers for phone, watch and earbuds

The factory

Our plant is in Guangming District, Shenzhen, 40 minutes from Bao'an International Airport. Design, mould making, injection, SMT, assembly, aging test and packing all happen on site — there is no third-party workshop in the chain.

• Two high-speed SMT lines with online AOI

• In-house mould and injection moulding division

• Automatic cell sorting, welding and laser marking

• Aging room where every finished unit runs a full charge–discharge cycle

• Around 300,000 units monthly capacity

How we work with brands

We take on two kinds of projects. In OEM, you bring the design or the reference sample and we quote tooling, unit cost and lead time. In ODM, you start from one of our existing platforms, choose the shell colour, finish, logo and packaging, and it ships under your brand.

• 10 in-house engineers covering structure, PCB and firmware

• First samples in 5–7 days, with a 3D render before tooling if the shell is new

• MOQ from 500 units on stock shells

• A dedicated project engineer assigned to every OEM order

• Weekly photo and video updates during production

Quality and compliance

Cells and PCBs are inspected on arrival, first-article inspection runs at every line change, and finished goods go through 100% function test and aging before packing. Production batch and cell batch are recorded against your order number, so a claim can be traced back to the exact lot.

Products ship with CE, FCC, RoHS, UN38.3 and IEC62133 documentation, with PSE, KC and UKCA available for those markets. UL testing is arranged on request. Test reports can be issued in your company name.

Where our products go

Our customers are brands, importers, promotional distributors and Amazon sellers. Shipments go to the United States, the United Kingdom, Germany, France, Canada, Japan, South Korea, India, Brazil, Chile, Mexico, Dubai and beyond. Several of our accounts have been with us for more than eight years, most of them starting from a trial order.

Beyond power banks

We also produce hand warmers, mini fans and lint shavers on the same lines. They are a smaller part of our business, and we keep them because long-standing customers like to consolidate seasonal accessories with the charging products they already buy from us.
