How To Fix Iphone Battery Not Charging

Can You Use Any Charger With Any Mobile Phone, Laptop, Camera, or Tablet? 

Every cell phone, notebook, and tablet appear to come with their own charger.  If you’re like me, you have probably compiled quite a few chargers over the years.  So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet computer that isn’t the original manufacturer’s charger that came with the device?

Types of Chargers

In this article, we will concentrate on three types of chargers: notebook chargers, micro USB chargers (these are used with telephones, tablet computers, and cameras), and Apple Lightning Connectors.  While some devices have chargers with a slightly different head or charging cable, these are the most frequent.

Laptop chargers are rather unique to the device they come with.  However, there can be some generic chargers that boast the capability to be interchanged between laptops.  This always requires changing of this charger”head” and might not be the optimal charging amperage or voltage for your device.

Micro USBs are theoretically designed to be interchangeable, and are standard in many smartphones, Android apparatus, and tablets.  Micro USB chargers typically have the exact same voltage, but may draw various amps.  I will explain this further later and how to know whether the charger is safe to use (depending on its recorded amps and voltage).

For older devices with a 30-pin charge port, a connector can be used to control the Lightning Connector.

The Plugs Must Be The Same

In order for a charger to be used on another device, it’s important that the plug  of the charger (the”head”) fit snugly to the charging port of the device.  Micro USBs are the same across the board as far as charging heads, while notebook chargers are usually specific to both make and model.  However, the plug fitting firmly is just one part of this equation.

Somewhere on the power brick of the charger you will find a tag with the charger’s voltage (V) and amperage (A).  For other types of chargers, like a smartphone charger, this information is usually found at the bottom of the charger, where it would meet up with the wall.  For the device you’re attempting to charge, the voltage and amperage required will be seen on the battery that came with the device or on the company’s website.

Voltage is how much power the charger will draw in the device, or how much is being”pushed” to the device by the charger.  A phone will usually pull up to around 5V, while a notebook can pull up to 25V.  A charger must equal the voltage needed by the device. 

Amperage is how quickly power is”pulled” to the apparatus, or how much electricity is used by the device.  The amount of volts won’t ever change, but the amount of amps that the system pulls may change based on how hard the device is working.  The number that you find on the battery that came with your device will be the maximum amount of amps that may be pulled by the device.  If a unit is paired with a charger that cannot support the amp necessity, it may burn out the power supply and kill the apparatus.

So for those who have a modern USB device (smart phone, tablet, or camera) you can plug into a high-amperage USB port and enjoy faster charging (so long as the voltage is equal).  *Site Note: if you have an older device, it may not work with USB ports that use the new Battery Charging Specification.

If The Micro USB  Charger’s Voltage Isn’t 5v…

Some devices might have their voltage recorded with a plus/minus on it like that: 5v +- 5%.  If this is true, you may use a charger rated at 4.75 to 5.25v because that score is telling you is that the apparatus can take 5v minus 5% of 5v = 4.75 volts  OR  5v plus 5% of 5v = 5.25 volts. 

An interesting thing to note is chargers supply a higher voltage than the batteries they charge.  That’s pretty much how they work.  There needs to be a voltage differential to generate the necessary current flow in the correct way to charge the battery.  When you look at your vehicle, it has a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.

Stay Away From Cheap Knockoff Chargers

The problem with knockoffs, particularly cheap knockoffs, is that they frequently don’t support the power requirements of the apparatus, or aren’t built to keep a steady flow securely.  Overall, it’s better to stick with the charger made for the device you’re using.

Now You Know How To Safely & Effectively Swap Chargers

I hope this article was able to assist you.  Now you know how to safely and effectively use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other device.  Be sure to follow exactly what we said and you should be good to go!
