Product Details
Pick the model by what the workshop actually charges. C1220 (7kg) is the portable one - dial the output from 5A to 20A and it covers standard commercial vehicles; C1230 (8.5kg) steps to 15-30A for delivery fleets and municipal trucks; C1250 (14.5kg) is the stationary station that pushes up to 50A for material handling hubs. Inside, all three are the same philosophy: an analog transformer base with a CPU firmware core, so the charging logic is firmware-driven but the power stage is simple and repairable.
The voltage presets are where AGM owners notice the difference - AGM sits at 14.4V (28.8V on a 24V pack), traction at 14.7V, EFB at 16.2V and starter at 15.8V - because AGM cells vent and dry out when pushed to the same numbers as a flooded battery. Input accepts 180-280VAC at 47-63Hz, the CPU current-limits the output, a manual reset switch clears over-current faults, thermal protection holds at 60 degrees C, and the cooling fan runs two minutes at startup then stops below 8A of load.

Our Company
Founded in 1993 in Guangdong, China, Huizhou Qiangfeng Power Technology Co., Ltd. manufactures battery chargers, inverters, voltage stabilizers, MPPT solar charge controllers and solar power systems, supplying international buyers with OEM/ODM service and factory-direct pricing.
Our Advantages
Chemistry Presets Do the Thinking
AGM, traction, EFB and starter voltages are pre-programmed (14.4V/28.8V, 14.7V, 16.2V, 15.8V), so a battery gets its own curve instead of a one-size-fits-all charge.
Simple Power Stage, Firmware Logic
An analog transformer base keeps the output stage straightforward and repairable, while the CPU firmware runs the charging decisions.
Proven in Tier-One Supply
The line is built by a contract manufacturer that supplies brands including YUASA, CAMEL, LEOCH, GS, BOSCH and Shaanxi Automobile Group.
