Shenzhen Green Ocean New Energy is a Chinese firm that builds batteries and other portable chargers. Spread across a 30-acre site, its crew of forty engineers tests every product so businesses receive dependable gear at reasonable prices. One popular item weighs only 2.8 kilograms yet packs a Type 2 socket, works on 100-240 volts, and switches between 3.5-kilowatt and 7-kilowatt output. Because the plant carries ISO 9001 plus CE, RoHS, and FCC seals, buyers can trust the chargers meet global rules. New orders are turned into custom samples in fifteen days, while warehouses in Germany and Thailand speed shipment and local help.
