I was talking about power outlet strips that are 'universal'. They are scarcer than hen's teeth. You won't find them in Thai Watsadu, Do Home, Home Hub, Amorn, Home Pro and most all other retail stores. I've only found one on lazada in the past 6 months and that was a Chinese import job so probably a fire hazard anyway. The last branded ones I bought almost 10 years ago were Belkin and Wanpro and both have superseded their local product line with Thai standard pin outs which emulates the 3-pin US style (with L & N reversed).
Universal wall receptacles are still available at hardware stores but they are going to be phased out, just like 'universal' power outlet strips.
