Exide Battery Charger Repair Parts

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

Every cell phone, laptop, and tablet appear to come with their own charger.  If you are like me, you’ve 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 that is not the original manufacturer’s charger that came with the device?

Types of Chargers

In this guide, we will concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with phones, tablets, 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 include.  However, there may be some generic chargers that boast the ability to be interchanged between notebooks.  This always requires changing of the charger”head” and might not be the best charging amperage or voltage for your device.

Micro USBs are designed to be interchangeable, and are standard in most smartphones, Android devices, 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 (based on its listed amps and voltage).

Apple Lightning Connectors are standard on all new Apple devices, including iPads and iPods. For older devices with a 30-pin charge port, a connector can be used to charge with the Lightning Connector.

For a charger to be used on a different device, it’s important 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, whilst notebook chargers are often specific to both make and model.  However, the plug fitting securely is just one part of this equation.

How Voltage and Amperage Matter

Determined by 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 located at the bottom of the charger, in which it would meet the wall.  For the device you are attempting to control, the voltage and amperage required will be found 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 apparatus, or how much is being”pushed” to the device by the charger.  A phone will usually pull up to approximately 5V, while a notebook can pull up to 25V.  A charger must equal the voltage needed by the device.  This is important: drawing too high a voltage could short out the device and possibly even begin a fire, while too low a voltage will fail to charge the battery.

Amperage is how fast power is”pulled” into the apparatus, or how much power is used by the device.  The quantity of volts will never 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 will be the max amount of amps which can be pulled by the device.  The amount found on the charger is how many amps can be pulled at once. If a device is paired with a charger which can’t support the amp necessity, it may burn out the power supply and kill the apparatus.

So if you 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 equivalent ).  *Website Note: if you have an older device, it might not work with USB interfaces that use the new Battery Charging Specification.

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

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

An interesting point to note is chargers supply a higher voltage than the batteries that they charge.  That is pretty much how they operate.  There needs to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery.  If you look at your car, it’s 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, particularly cheap knockoffs, is they often don’t support the energy needs of the device, or aren’t built to maintain a steady flow securely.  Overall, it’s better to stay with the charger designed for the device you are 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 efficiently use a charger that did not come with your smart phone, notebook, camera, tablet, or other apparatus.  Make certain you follow exactly what we said and you should be ready to go!
