I also noted that the cable supplying this piece of crap was very underrated for it's use. The cable had a quoted size of 1mm² as to the very minimum standard of 1.5mm², and the manufacturers call that "upgraded". Send it back, or if your too late, bin it. Rated for 2500W by a 10A fuse… |

I have just looked closely at the picture and see what you mean by no earth. In fact there is no plug in existance that fits the lower two outlets. Another design fail. Send it back and next time get a long close look at the picture presented by Amazon. I made this mistake buying gear that had schuko plugs and then had to buy adapters. I'm talking rubbish again. My eyes are playing up again. Can't see anything wrong with it when I enlarge the photo. |

For the electronic enthusiasts here on the forum - two, three? - a remark about the galvanic isolation of telephone chargers. We all know: using your phone in the bathtub while plugged into a charger should be avoided. The first question with these cheap usb chargers is: any galvanic isolation inside? If you want to take care of that, it comes at a price. No application notes here, a summary by Digi-Key: Techniques and Solutions for USB Power and Data Isolation. A second question: how reliable is the 5 volt supply in such a cheap extension block? You don't want to see a sudden overvoltage. Preferring to take a walk on the safe side - others don't - I personally use the original power supplies of Samsung, Apple & the rest. |

It really is not a problem, the regs specify a minimum conductor size because to give a range of conductor sizes and lengths would be unworkable, you would not want to draw 16 amps over 100m using 1.0mm2 but it wouldn't fry, the voltage drop would exceed the allowable tolerance but not be massive.
If you take it to its extreme and if you can remember old style rewirable fuses on a length of 4 or 5 cm a minute strand of wire will carry 13 amps all day long without volt drop and will only fail if 3 times the current is passed continuously.
Common sense should prevail and it seems you are already using that, you would not want to put a 3kw heater on all 6 of the outlets but the circuit that it is plugged into would protect against that, also the 13 amp plug on the end although you may have changed that for a French one, if you do that remember you are removing the first line of overcurrent protection.

@ PCPA, old style rewirable fuses: perhaps useless, but you never know, made by Legrand. |

I had those and the exact same card when I moved in here, the new house does also but being 1966 it might be cartridge fuses, every single point of contrôle on the diagnostique éléctrique was a non conformité or défaillance majeure, rewirable or cartridge I don't care as I will be ripping it all out straight away.
