What to name in your inquiry
Name the battery types the charger must serve: the batteries your team already uses, or plans to use. A charger must match the battery type it charges, and a charger chosen without the battery in mind is a guess. Name how many batteries must be ready at once, where charging happens, and what power sources are available on location.
Name the quantity you have in mind, and the market you sell into. The charger selection guide explains the types — dual, USB, universal, and V mount battery chargers — and the pairing guide explains how batteries and chargers work together. An inquiry that names the battery types and the workflow will receive a specific answer.
Four confirmations, before payment
First, the minimum order quantity for your order, and whether it differs by charger type. Second, the lead time, with its meaning: whether it counts from order, from payment, or from production start. Third, the specification for the exact type, so the goods can be checked against it on arrival. Fourth, the certificates that apply to your market, by name, with documents attached.
Certificates are available upon request; the inquiry is where you name your market and ask for the documents that apply to it. A supplier who answers all four in writing, with documents, is a supplier whose order can proceed.
Before payment, confirm the minimum order quantity and lead time for your order. Certificates are available upon request.
What not to assume
Do not assume that a charger that serves one battery type serves another, that a charging speed figure describes a charger fully, or that a USB charger will work from every USB source in every location. Each assumption is a common cause of a wrong order, and each is avoided by naming the battery types and the workflow in the inquiry.
