Studios and location shoots
Studios charge in one place, with mains power available and time to spare. A studio charger can be larger, can charge several batteries at once, and does not need to travel. The studio workflow values capacity and simultaneity: how many batteries are ready when the shoot starts, not how fast one battery charges.
Location shoots charge where the shoot happens, with whatever power is available: a vehicle, a power bank, a wall socket found on site. A location charger must be portable, must draw from the sources available, and must be robust enough for transport. A USB charger serves a location shoot well, because USB sources are the most widely available power on location.
Teams and events
Teams need several batteries ready at once, which makes dual chargers and multi-bay charging a workflow choice, not just a product choice. A team that runs several camera kinds needs a charger strategy, not just a charger: which chargers serve which batteries, and how many of each are needed. The pairing guide explains the matching, and this guide explains the workflow it serves.
Events need charging that fits the event's schedule: batteries charged before the event, topped up during breaks, and ready for the next session. An event charger must fit the breaks, not just the batteries: a charger that needs longer than the break allows will leave batteries unready. Naming the schedule in the inquiry prevents that failure.
What to ask next
Name the workflow: where charging happens, how many batteries must be ready at once, and what power sources are available. Ask for the specification for the exact type, the quantity terms, the lead time, and the certificates for your market, by name, with documents attached. The bulk charger inquiry page lists these confirmations.
Before payment, confirm the minimum order quantity and lead time for your order. Certificates are available upon request.
