▍ Gịnị bụ PSE Asambodo?

PSE (Nchekwa Ngwaahịa nke ngwa eletriki & ihe onwunwe) bụ usoro asambodo amanyere na Japan. A na-akpọkwa ya 'Compliance Inspection' nke bụ usoro nnweta ahịa nke amanyere maka ngwa eletriki. Asambodo PSE nwere akụkụ abụọ: EMC na nchekwa ngwaahịa yana ọ bụkwa ụkpụrụ dị mkpa nke iwu nchekwa Japan maka ngwa eletriki.

▍ Asambodo maka batrị lithium
