How Can I Repair My Laptop Battery

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

Every mobile phone, notebook, and tablet appear to come with their own charger.  If you are 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, laptop, camera, or tablet that is not the original manufacturer’s charger that came with the device?

Types of Chargers

In this guide, we’ll concentrate on three types of chargers: laptop 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 fairly specific to the device they include.  However, there can be some generic chargers that boast the ability to be interchanged between notebooks.  This always requires changing of this 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 most 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 (based 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

For a charger to be used on another device, it’s important 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 as far as charging heads, while laptop chargers are often specific to both make and model.  However, the plug fitting securely is just one part of this equation.

Determined by the power brick of the charger you’ll 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 base of the charger, in which it would meet up with the wall.  For the device you are 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 in the device, or just 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 device, or how much electricity is used by the device.  The amount of volts won’t ever change, but the quantity of amps that the device pulls may change based on how hard the unit is working.  The number that you locate on the battery that came with your device are the max amount of amps that may be pulled from the device.  If a unit is paired with a charger that cannot support the amp requirement, it may burn out the power source and kill the device.

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

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

Some devices might have their voltage listed using 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 apparatus can take 5v minus 5% of 5v = 4.75 volts  OR  5v and 5 percent of 5v = 5.25 volts.  This means anything between 4.75 t0 5.25v is safe to use (so long as the amperage of the charger is equal to or greater than the device’s listed amperage).

An interesting point to note is chargers provide a higher voltage than the batteries they charge.  That is pretty much how they work.  There has to be a voltage differential to generate the necessary current flow in the correct way to charge the battery.  If you look at your car, 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 problem with knockoffs, especially cheap knockoffs, is that they frequently don’t support the power requirements of the apparatus, or are not 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 Know How To Safely & Effectively Swap Chargers

I hope this article was able to help you.  Now you know how to safely and efficiently use a charger that did not include your smart phone, laptop, camera, tablet, or other apparatus.  Make sure you follow exactly what we said and you should be ready to go!
