You may possibly have witnessed some of the EEVblog dumpster dive films, exactly where [Dave Jones] at times finds properly fantastic products which is been tossed out. But this time, rather than a significant display monitor, desktop laptop or computer, or a photocopier, he attributes a stash of 283 electrical outlet double adapters that he observed very last year. He decided to complete a check in the parking lot, connecting all 283 adapters in series.
Utilizing a pair of power meters and a 2 kW electrical heater as a exam load, [Dave] and his son [Sagan] measure the loss as a result of this wild set up. It performs out to about about 300 W, or roughly 1 W for each adapter. He did a abide by-up experiment working with a FLIR thermal digicam, and confirmed that the power reduction is reasonably uniform, and that no single rogue adapter consuming all the dropped energy. Following a back of the envelope calculation, we estimate this chain of adapters is about 20 meters lengthy, generating this complete factor completely pointless but intriguing even so. Stick close to until eventually the close of the video clip for a teardown — they’re not as cheaply produced as you may consider.
[Dave]’s outrageous experiment apart, we do marvel why an individual experienced so lots of adapters to throw away in the first put. What would you have performed with 283 adapters — remaining them in the dumpster or rescued them?
