Rating: 5.0 (50 reviews)

The Fuyuang FY4204000 delivers 42V 4A (168W) for 36V lithium-ion battery packs, making it a practical charger for e-bikes, e-scooters, cleaning robots, electric wheelchairs and portable power stations. Input is 100-240VAC 50-60Hz and charging efficiency is 90%. Charging uses a CC-CV floating profile that ends with a shut-off, so the pack is left in a safe state. Protection covers short circuit, overload, over-voltage, over-temperature, over-charging and low tension, and the LED indicator shows charging progress. The fanless design cools by free air convection inside a 178*80*46MM PC fireproof housing weighing 0.80kg. Fuyuan Electronic Co., Ltd has manufactured chargers since 2005 and runs 108,000 m2 of production space with a CNAS-standard EMC laboratory.
