How do I charge JBL Go Portable speaker? In the specification, what should be the input supply? Voltage is not mentioned. Can I use my mobile charger?
If the charging voltage is not mentioned, then the default voltage is 5V & most probably you have also got a USB cable, so that means it needs 5V to charge. From manufactures website I found out that it has 3.7V, 600 mAh battery, which requires 1.5 hours to charge, so that means it requires at least 300mA charger having MUST 5V. So you can use any 5V charger or you can also charge it with your laptop or desktop.
Can I use the USB port on my AirPort Extreme to charge...?
It should work. USB ports are generally set up to provide at least 500 mA of current at 5 V. For comparison, the 5W Apple charger (the white cube) can put out 1000 mA at 5V and will charge an iPhone much more quickly. If you are no hurry, a USB port will work just fine. Try it. If the iPhone shows it is charging, then it works.
Does a micro USB charge cable also transfer data?
The answer is NOT NECESSARILY, BUT MOST OF THEM DO.Unless you have electronics testing instrument or a connectivity tester with iron-strong and very precise hands, the only way to know if a cable can be used for data transfer, is to plug it and test it with your computer and mobile device.There is a very good reason why you may want a charge-only cable. If you are at a strange place, say an airport, you can not know if any USB outlet you are plugging your phone to, is actually a power charger and nothing else. We have all read nefarious charging ports, siphoning data from your phone or worse, injecting malware to it, when you think all you are getting is some more juice for your mobile device. In cases like these, using your charge-only cable is a necessity.
How come iPhone charger cords go bad?
Here the shiny premium Apple cord.Here a peasant ugly Android charger cable.The difference is in the connector.Have you noticed that the Apple cable has just a cylinder while the micro USB cable has a sort of a slotted cone?The cone is not a choice for looks, but a necessity to unload the mechanical stress on the connector, to specifically avoid breaking because of repetitive torsions.See how the Apple cable breaks just after the smaller cylinder? In the same place where the black USB cable has a slotted cone.Oh my… Comments highlighted how probably iPhone bearers mistreat cables, bringing them to the aforementioned premature death:Coiling cable tightlyDisconnecting them by pulling from the cableTwisting the cable, knotsWhile these are the tortures that await anybody that for a karma misadventure reincarnate as an Apple cable, I have to say my humble opinion that I do worse things on my USB cables and they are still alive to tell, or at least share data and charge.Anyway if you want to prolong the life of your mighty cable, connect and disconnect it by grabbing the solid part of the connector. Storing it in a rigid case may also help in case of rough travel.Some suggest coiling a spring or reinforcing with rubber or just plain repair tape.The worst in all this cable gate matter is that they sell these cables at outrageously high prices.Aw, that’s was mean review.In conclusion, a cable that breaks due to normal use is bad engineering, and there is no excuse to that as other cables do fine after decades of daily use.
Why does my iPhone and the plug to the charger get so hot sometimes?
Your houses power is typically at a much higher voltage than a cellphone can use. Typically a cellphone will charge on anything around 5.5 volts (this is a rough estimate based on a computer’s usb voltage). Your house’ power can be anything from 110 V to 220 V depending on where you live. The end result is that if you want to charge your phone directly from a wall socket you need to bring the voltage down to do so. Your cellphone’s charger does this automatically by means of a built in charge circuit. This charge circuit generates its own heat when it’s doing it’s job. This is why a cellphone charger will get hot.A battery works because of chemistry. When you charge it you are reversing chemical reactions inside the battery. These chemical reactions generate heat. This is why a battery gets hot. This is also why you don’t want to overcharge batteries or connect them to voltages that are too high. In extreme cases like that those chemical reactions can make a battery go pop.
