Apple supplies a Lightning-to-USB-C cable with the latest iPhones. If you have an iPhone, the answer could be yes, since the phones still employ Apple’s proprietary Lightning connector, which has been a staple on the company’s handsets since the iPhone 5 was released in 2012 (that’s when Apple replaced the 30-pin dock connector that had been on prior models).īut the answer can also be no. In conclusion I'd say lightning connectors perfectly safe and you should have nothing to worry about.The short answer is maybe, and it depends on the device. (people better at me in electricity please do correct me if there are any mistakes) In both cases, the fuel (volts) doesn't really play a very big part in the analogy. However, if the car is travelling at low speeds, the person is less likely to get severely injured. If this car were to hit someone at high speed (equivalent to high amps) the person could get severely injured (a similar effect is seen in high-amperage electrocution). Think of a charge as a car, volts as fuel and amps as speed. Physics.SE and Electrical Engineering.SE probably have people who understand electricity better than I ever will, but I'll try and give an explanation: As mentioned in the thread, the amount of volts helps the charge travel easier. What causes electric shocks is the amperage, the higher the more lethal. Reason being, the lightning connector puts a charge though at 5V with a negligible amount of amperage (not going to break out the ammeter to find out). It should be very safe, if not harmless, for your children. In summary, whilst lightening is exposed and there are better, less exposed connectors, if your using a good quality power supply from a reputable manufacturer on an RCD protected circuit, I'd say the risks are minimal. These are calibrated so normally they trip quicker and at a lower current than is required to cause the body issues, but only after the initial painful shock (I speak from personal experience). the current is flowing through you instead, they turn the power off. These devises measure the current flowing out vs the current flowing back (simplified) and if there is a difference, i.e. I'll have to just speak for the UK here as I don't know the regulations elsewhere well enough, but all modern domestic circuits have RCD protection. That's not the end of the story though, whilst you may get a shock from a faulty/low quality power supply, and it will probably hurt, there are still other devices to protect you.
As there isn't the isolation, this could result in a nasty mains voltage shock. This means that although the voltage between + and - is only 5V, there could be mains voltage between the low voltage side and earth/ground or any conductive materials connected to it (appliances etc). In the event of a faulty/low quality power supply however there may not be the electrical isolation between the mains and low voltage sides. In this case it is still safe because earth/ground does not form a complete circuit. A good quality power supply will isolate the low voltage side from the mains voltage, as well as actively regulating the current and voltage passed. If however were talking about a mains power supply, then that is the most important part. You can test this with a standard 9V battery on your tounge, it tickles but doesn't hurt, although I wouldn't recommend long term exposure due to DC bias, but that's another story. Under the best case scenario this will come from a battery pack, forming a closed circuit, you might get a very small tingle but nothing too dramatic as the potential isn't enough to go through human tissue and cause and real damage. Lighting is a USB standard so we have 5V there, usually up to 2A. I realise this isn't electrical engineering SE, but you asked for sound answers so I'll attempt to elaborate.Īs others have stated the most important thing isn't the cable but what it's plugged in to. Whilst this is usually totally safe, there's a few caveats.
