Start from the batteries

A charger must match the battery type it charges, and a charger chosen without the battery in mind is a guess. List the battery types your team uses: the camera kinds, the battery types within them, and how many of each. A charger that serves one type may not serve another, even when the two batteries look similar, and a charger strategy that covers only some of your types will leave the rest uncharged.

Count the batteries, not just the types. A team with ten batteries of one type needs a different charging plan from a team with two batteries of five types. The first team needs simultaneity: several batteries charged at once. The second team needs coverage: one charger, or several chargers, that together serve all five types. The charger selection guide explains the types, and the pairing guide explains the matching.

Single and dual chargers

A single charger charges one battery at a time. It suits a creator with one or two batteries, where charging happens overnight and time is plentiful. A dual charger charges two batteries in one session, which suits a team or a long shoot, where several batteries must be ready at once and charging time is limited. The difference is workflow, not quality: a single charger is not worse than a dual charger, it is slower for several batteries.

Count charging sessions, not just chargers, when deciding. A team with six batteries and single chargers needs six sessions; the same team with dual chargers needs three. If charging happens overnight, six sessions may be fine. If charging happens between takes, three sessions may still be too many. The schedule decides the charger, and the inquiry should name the schedule.

USB chargers

USB chargers draw power from a USB source: a laptop, a power bank, a wall adapter, or a vehicle socket. That makes them useful on location, where mains power may not be available and the only power is what the team carries. A USB charger trades speed for flexibility: it charges wherever USB power exists, but it depends on the USB source's capability, which varies.

A USB charger is not automatically a universal charger, and a universal charger is not automatically a USB charger. The two descriptions answer different questions: USB answers where the power comes from, universal answers which battery types it covers. An inquiry should ask both questions separately, because a charger can be one without being the other, and assuming otherwise is a common error.

Universal chargers

A universal charger aims to cover several battery types with one unit. Its value is coverage: one charger for a team that runs several camera kinds, instead of a different charger for each. Its risk is partial coverage: a charger that covers three of your four types is not universal for your team, whatever its description says. Coverage should be confirmed type by type, in the inquiry, by naming each battery type you use.

Universality also has a workflow cost: a universal charger that serves several types may charge each type in turn, not at once, which changes the charging schedule. A team that needs several batteries ready at once should ask whether the universal charger charges simultaneously or sequentially, because the answer changes how many chargers the team needs.

V mount battery chargers

V mount battery chargers serve the larger V mount batteries, and they belong with the V mount line rather than with the general charger line. A V mount battery is larger, powers more, and mounts on a rig, and its charger must match that battery specifically. A general charger cannot be assumed to serve a V mount battery, and an inquiry for V mount charging should name the V mount battery type explicitly.

The distinction matters because a buyer who orders a general charger for a V mount battery will receive a charger that does not fit, and the error will only be discovered when the battery needs charging. Naming the battery type in the inquiry prevents that error, and it costs nothing to be specific. The V mount applications guide explains the batteries themselves.

Charging on location versus in a studio

A studio charges in one place, with mains power and time to spare. A studio charger can be larger, can charge several batteries at once, and does not need to travel. A location charger must be portable, must draw from the sources available on location, and must be robust enough for transport. The two workflows need different chargers, and a charger chosen for one may fail in the other.

A team that does both needs both, or a charger that serves both, confirmed as such. The charger applications guide explains the workflows in full. An inquiry that names the workflow — studio, location, or both — will receive a charger recommendation that fits it, and an inquiry that names neither will receive a general recommendation that fits neither well.

What the charger descriptions do not tell you

Charger descriptions tell you the type: single, dual, USB, universal, or V mount. They do not tell you the charging speed for your battery type, the power source requirements, or the certificates that apply to your market. Those answers come from the specification for the exact charger type, confirmed in the inquiry, not from the type description. A buyer who assumes a speed from a type name alone will assume wrongly.

Charger descriptions also do not tell you the quantity terms or the lead time. Those are order terms, confirmed in the inquiry, not properties of a type. The bulk charger inquiry page lists the confirmations, and the inquiry process page explains the sequence.

Questions this guide raises

What battery types do you use, and how many of each? How many batteries must be ready at once, and where does charging happen? Does a universal charger cover all your types, and does it charge simultaneously or sequentially? Those questions, answered in your inquiry, will produce a specific reply, and a specific reply is the basis of a safe order.

If any answer is missing from your inquiry, add it before sending. A missing answer is a question the supplier must ask back, and every round of questions costs time. A complete inquiry, naming the battery types, the workflow, the quantity, and the market, is the fastest route to a confirmed order.

A final word on choosing well

Choosing a charger well means naming the batteries first, the workflow second, and the charger third. A charger chosen in that order will serve its batteries and its workflow; a charger chosen by a single figure, or by a general description, may serve neither. The order of decisions matters as much as the decisions themselves.

If you are unsure, name your batteries and your workflow in the inquiry, and let the supplier confirm the type. An inquiry that describes the need precisely will receive a precise recommendation, and a precise recommendation is worth more than a catalogue page of general descriptions.
