Smart plugs overheating: the problem nobody mentions
Users report 16A smart plugs heating up with 2000W loads. Design flaw or inflated specs?
English · Original discussion in Spanish · Published
A user who had bought several smart plugs to control household loads – including battery charging – ran into an unexpected problem: the devices, even those rated for 16A, reached alarming temperatures with consumption below 3000W. After testing Ecoflow models (limited to 10A) and Eightree plugs (whose label says they support 16A but which heat up to the point of scorching), the experience points to a recurring pattern: the real specification does not match the advertised one.
According to several analyses by technically savvy users, the problem lies in the internal relays and contacts, often of poor quality in low-cost products. An electrician who has peine faulty devices says the wire gauges and the mini relays they use are insufficient, and jokes that "Chinese amps" should be called "champs". The technical recommendation is to use industrial contactors instead of conventional plugs, or at least to buy models with a safety margin, such as 20A ones, so they operate more comfortably.
Meanwhile, the offering on Amazon and AliExpress remains flooded with WiFi plugs promising 16A and energy monitoring for under 10 euros. Some users report years of trouble-free operation with pool pumps or fridges, but premature failures with water heaters. The question that remains: is the market sacrificing safety for price?
