Small adapters, real engineering
A 5V 1A adapter looks trivial. It is not: at that size the transformer, the safety spacing and the thermal path all compete for the same cubic centimetres. Consistent tooling and incoming material control are what keep the failure rate down at volume.
Volume pricing without quality drift
Because we build in-house, a 100,000-piece 5V order goes through the same ageing and hipot test as a 1,000-piece order. Price comes down with volume; the test procedure does not.
Common configurations
5V 0.5A / 1A / 2A / 3A / 4A, fixed or interchangeable plugs, 5.5×2.1mm DC, 1.2m or 1.5m cable, white or black housing, Level VI efficiency.
