How many batteries at once
A dual charger serves two batteries, a triple charger three, and a four-slot charger four. More slots mean more batteries ready together, but each battery may charge more slowly, as the triple and four-slot model pages show: output current falls as more slots are filled. A team that needs many batteries ready together should plan for the slower per-battery rate, not assume full speed for all slots.
A single-slot charger suits a single shooter with one or two batteries, where one battery charges while the other is in use. The choice is about workflow, not just about numbers: a team and a single shooter need different chargers.
Universal and travel chargers
A universal charger claims to serve several battery types, and its output range describes the voltages it covers. A universal claim should be checked against each battery type it must actually serve, because a voltage range alone does not guarantee fit or connector match. The universal model page explains its claim and its limits, and the inquiry is the place to confirm coverage.
A travel charger is compact and covers a wide input voltage range, for use in different locations. It suits a shooter who charges on the move, where a larger charger would be a burden. Check the input range against the locations where it will be used, and confirm in the inquiry.
Input, output, and power together
Input describes how the charger is powered: USB-C, Micro, or AC mains, at a stated voltage and current. Output describes what the charger delivers to the battery: voltage and current, per slot where stated. Power describes the charger's total output, where stated. All three together describe a charger, and a charger with the right output but the wrong input cannot be powered.
Do not choose by a single figure, and do not assume a figure for a model that does not state one. Check the specification table against the batteries and the workflow, and confirm in the inquiry.
What to confirm before ordering
Name the model, the battery types it must serve, the quantity you have in mind, and the market you sell into. Ask for the specification for the exact model, the minimum order quantity, the lead time with its meaning, the warranty terms, and the certificates that apply to your market, by name, with documents attached.
Before payment, confirm the minimum order quantity, lead time and warranty terms for your order. Certificates are available upon request.
