|---|---|---|---|---|
| 8.4V | 2A / 3A | 16.8W / 25.2W | 2S (7.4V) | Walkie‑talkies, portable speakers, small vacuum cleaners, children's toy cars, medical nebulizers, electric toothbrush charging bases |
| 12.6V | 1.5A / 2A | 18.9W / 25.2W | 3S (11.1V) | Electric screwdrivers, portable fans, electric toy guns, 3D printing pens, small massagers, LED photography lights |
| 16.8V | 1.5A | 25.2W | 4S (14.8V) | Portable printers, portable monitors, electric scooters (lightweight), cordless vacuum cleaners, robotic vacuum cleaners |
| 21V | 1.2A | 25.2W | 5S (18.5V) | Electric wrenches, cordless chainsaws, high‑power electric screwdrivers, self‑balancing scooter chargers, some e‑bike chargers |
| 25.2V | 1A | 25.2W | 6S (22.2V) | Underwater LED lights, drone battery chargers (6S), medical rehabilitation physiotherapy devices, electric skateboards (high voltage) |
※ Constant current charging with LED indicator: Red light during CC stage, switches to green or off when fully charged. Suitable for Li‑ion battery packs (nominal 3.6V/3.7V, full charge 4.2V per cell).
Core Features of Constant Current Charger
CC/CV charging curve: Constant current fast charging → constant voltage trickle charging, effectively protects battery life.
Smart LED indicator: Red light during charging, turns green or off when fully charged – status at a glance.
Multiple safety protections: Overvoltage (OVP), overcurrent (OCP), short circuit (SCP), over temperature (OTP), optional reverse polarity protection.
Wide voltage input: 100-240V AC, universal use.
Full certifications: CCC/CE/UL/FCC/UKCA/PSE etc., compliant for target market access.
???? Selection & Customization Advice
Strict voltage matching: Output voltage = number of cells in series × 4.2V (e.g., 3‑cell Li‑ion must use 12.6V charger).
Current selection: Recommended 0.2C~0.5C of battery capacity; higher current reduces charging time but requires battery support.
Connector customization: DC plug types (5.5×2.1/2.5, Type‑C, aviation, magnetic), cable length (0.5m~2m) can be customized.
Housing options: Wall‑plug or desktop type, with or without pass‑through, standard DC cable output.
