How To Repair Dell Battery

Can You Use Any Charger With Any Cell Phone, Notebook, Camera, or Tablet? 

Every mobile phone, notebook, and tablet seem 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, laptop, camera, or tablet computer that isn’t the original manufacturer’s charger which came with the device?

Kinds of Chargers

In this article, we will focus on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablet computers, and cameras), and Apple Lightning Connectors.  While some devices have chargers using 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 notebooks.  This always requires changing of the charger”head” and might not be the best charging amperage or voltage to your device.

Micro USBs are designed to be interchangeable, and are standard in many smartphones, Android devices, 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 whether the charger is safe to use (depending on its listed amps and voltage).

For older devices using a 30-pin charge port, 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 snugly to the charging port of the unit.  Micro USBs are the same across the board as far as charging heads, while notebook chargers are often specific to both make and model.  However, the plug fitting securely is just one part of this equation.

Somewhere on the power brick of the charger you’ll find a tag with the charger’s voltage (V) and amperage (A).  For laptop chargers, this charging brick is often halfway down the charger and appears exactly like it sounds — a brick. 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 trying to control, the voltage and amperage required will be seen on the battery that came with the device or on the manufacturer’s website.

Voltage is how much power the charger will draw into the device, or just how much is being”pushed” to the apparatus by the charger.  A phone will usually pull up to approximately 5V, though a notebook can pull up to 25V.  A charger must equal the voltage required by the device. 

Amperage is how fast power is”pulled” into the device, 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 depending 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.  If a device is paired with a charger that cannot support the amp necessity, it may burn out the power source 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 quicker charging (so long as the voltage is equal).  *Website Note: if you have an older device, it might not work with USB interfaces that employ the newest Battery Charging Specification.

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

Some devices may have their voltage recorded with a plus/minus on it like that: 5v +- 5%.  If this is the case, 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 plus 5% of 5v = 5.25 volts.  So this means anything between 4.75 t0 5.25v is safe to use (as long as the amperage of the charger is equal to or higher than the device’s listed amperage).

An interesting point to note is all chargers supply a higher voltage than the batteries they charge.  That is pretty much how they operate.  There has to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery.  If you look at your vehicle, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.

Stay Away From Cheap Knockoff Chargers

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

Now You Know How To Safely & Effectively Swap Chargers

I hope this article was able to help you.  Now you know how to safely and effectively use a charger that did not come with your smart phone, notebook, camera, tablet, or other device.  Be certain you follow exactly what we said and you should be ready to go!
