A manufacturer and supplier, in its own published words
Shenzhen Doublepow Energy Technology Co., Ltd. describes itself as specialising in the research and development, manufacture, sales and service of rechargeable batteries, battery chargers and consumer electronics. That sentence is the company's own published positioning, and this site keeps it in that form: a statement of what the company says it does, not an independent audit of its operations.
The company profile states that the company was founded in 2012 and is based in Shenzhen, Guangdong, near Hong Kong. The same profile states a plant area of 10,000 square metres and a monthly output of more than 2,000,000 batteries and more than 1,000,000 chargers. Those figures are repeated on this site only with their attribution attached, because they come from the company profile and have not been independently verified for this site. A buyer who needs verified capacity evidence should ask the supplier for it directly, for example through a factory audit, which the company service page says it supports.
The company profile also describes a professional research team, experienced workers and advanced equipment. That description is reported here in the same attributed form. It is not expanded into headcounts, qualifications or equipment lists, because the published record does not supply them, and inventing them would mislead a buyer who is trying to judge a supplier.
What the company website actually sells
The company website organises its range into four top families. Cylindrical batteries form the largest family, with sub-families for 1.2V nickel batteries, 1.5V lithium ion batteries, 3.2V lithium iron phosphate batteries, 3.7V lithium ion batteries, dry batteries and cylindrical USB rechargeable batteries. Energy storage batteries form the second family, with titles covering wall-mounted, stacked, block-cell, recreational-vehicle, outdoor and mobile forms. Battery chargers form the third family, with thirty-nine listing titles across B, D, K and UK series. Fans and other hot sellers form the fourth family, with nineteen listing titles including clip fans, a desktop mini fan and a portable outdoor camping fan.
The company's service page adds a second layer to that catalogue: custom production, mould making with its own and partner factories, testing reports for compliance certificates, factory audit support and after-sales warranty support described as worldwide. Those services are relevant to a trade buyer because they change what an enquiry should ask about. A buyer who only needs standard listings can ignore them; a buyer who needs a custom size, a custom combination or a compliance report for a particular market should raise it in the first message, since it changes the sampling and confirmation steps that follow.
Two things this page deliberately does not do. It does not name export countries or customer cases, because the published record contains no export country list and the page titled as a cases page on the company website is in fact a product listing. It also does not present any photograph as the company's own factory or product photograph, because the published images carry no such attribution. Where this site needs a picture, it uses a labelled line diagram and says so.
Certifications and verification, kept apart
The company website names CE, ROHS, SGS, UN38.3 and MSDS, and describes its factory as holding ISO 9001:2008 certification, with the year exactly as published on the company website. This site repeats those names with the trade wording that certificates are available upon request, and it publishes no certificate number, issuing body or validity date. The ISO year is not modernised: updating it would misrepresent the published record.
Separately, the company's marketplace storefront is recorded as a Verified Multispecialty Supplier, verified by SGS, with nine years of operation and a Guangdong location. That record describes the storefront, not a battery, and this site does not merge it with the product certification names. A buyer should treat the two as different kinds of evidence and ask for the document that matches the question being asked: a product certificate for a product question, and storefront verification for a storefront question.
How to judge this supplier from this site
A fair reading of this site is that it gives a buyer a well-organised shortlist and a disciplined enquiry route, and that it refuses to fill gaps with invented detail. The gaps are real: listing titles without full specifications, no published price, no published minimum order quantity and no published lead time. Those gaps are stated on the relevant pages rather than smoothed over, and the enquiry checklist at the foot of every page exists to close them with the supplier, in writing, before an order is placed.
Buyers who need stronger evidence before committing should ask for it in the first enquiry: a full specification sheet for the exact listing title, the certificate documents named on this page, a sample under the company's published sampling step, and audit support if the order justifies it. The contact route for all of that is the published contact page route: Manager Geely Zhang, telephone +8615975606040, email [email protected].
What to send with your enquiry
To get a useful answer first time, please include the following in your message. Every item on this list is a question for the supplier to confirm, not a claim made on this page.
- The battery size family you need (for example AA, AAA, 18650, 21700 or 26650) and the listing title exactly as published on this site.
- Your quantity range, so the supplier can confirm the quantity terms that apply to your order.
- For chargers, the plug style and the battery sizes the charger must serve.
- For fans, where the fan will be used — desk, clip-on, handheld or outdoor — and whether it must run while charging.
- Three questions to ask before you order: please confirm the full specification, please confirm the quantity terms, and please confirm the lead time for this listing.

Planning reference for quantity and lead time
Orders in this trade are commonly discussed in the low thousands of pieces for standard cells, and lead times are commonly measured in weeks once a specification has been agreed. Those are trade planning figures, not this company's published policy: the company's own website does not publish a minimum order quantity or a lead time. Before you place an order, please confirm the quantity terms and the lead time that apply to your listing, in writing, and please do not treat this paragraph as a price or delivery promise.
Prices are not published on this site. Please ask for a quotation against the exact listing title, and please confirm the specification, the quantity terms and the lead time before payment.
