How To Repair Your Iphone Battery

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

Every mobile phone, laptop, and tablet appear to come with their own charger.  If you’re like me, you’ve probably compiled a number of 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 which came with the device?

Types of Chargers

In this guide, 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.  Although some devices have chargers with a slightly different head or charging cable, these are the most common.

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

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

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

For a charger to be used on another device, it’s essential that the plug  of the charger (the”head”) fit securely into the charging port of the unit.  Micro USBs are the same across the board so far as charging heads, whilst notebook chargers are often specific to both make and model.  However, the plug fitting securely is just 1 part of the equation.

Somewhere on the power brick of the charger you will find a label 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 the wall.  For the device you are 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 into the apparatus, or just how much is being”pushed” to the apparatus by the charger.  A phone will usually pull up to around 5V, while a laptop can pull up to 25V.  A charger must equal the voltage required by the device. 

Amperage is how fast power is”pulled” into 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 device pulls may change based on how hard the device is working.  The number that you locate on the battery that came with your device are the maximum amount of amps that can be pulled by the device.  The amount found on the charger is how many amps can be pulled simultaneously. In order to swap chargers, the amp number on the charger must equal or exceed the amp number listed on the device’s battery. If a device is paired with a charger which can’t support the amp necessity, it may burn out the power source and kill the apparatus.

So if you have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (as long as the voltage is equal).  *Website Note: if you have an older device, it may not work with USB interfaces that employ the new Battery Charging Specification.

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

Some devices may have their voltage listed 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 rating is telling you is that the apparatus can take 5v minus 5% of 5v = 4.75 volts  OR  5v and 5 percent 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 produce the necessary current flow in the correct way to charge the battery.  When you look at your car, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.

The problem with knockoffs, especially cheap knockoffs, is that they frequently don’t support the energy needs of the device, 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 Understand 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 come with your smart phone, laptop, camera, tablet, or other device.  Be sure you follow what we said and you should be good to go!
