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

Every mobile phone, laptop, and tablet seem to come with their own charger.  If you are like me, you’ve probably compiled quite a few chargers through 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?

Types 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 rather specific to the device they come with.  However, there can be some generic chargers which boast the ability to be interchanged between notebooks.  This always requires changing of this charger”head” and might 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 will 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.

In order for a charger for use 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 so far as charging heads, whilst laptop chargers are usually specific to both make and model.  However, the plug fitting securely is only 1 part of the equation.

Somewhere on the power brick of the charger you will get a tag with the charger’s voltage (V) and amperage (A).  For notebook 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 located at the base of the charger, in which it would meet 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 apparatus, or how much is being”pushed” into the device by the charger.  A phone will usually pull up to around 5V, though a laptop can pull up to 25V.  A charger must equal the voltage needed by the device. 

Amperage is how quickly power is”pulled” into the apparatus, or how much power is used by the device.  The amount of volts will never change, but the quantity 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 max amount of amps that can be pulled from the device.  The number found on the charger is how many amps can be pulled simultaneously. To be able to swap chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. If a unit is paired with a charger which can’t support the amp requirement, it can 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 faster charging (as long as the voltage is equivalent ).  *Site Note: if you have an older device, it may 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 recorded with a plus/minus on it like this: 5v +- 5%.  If this is the case, you can use a charger rated at 4.75 to 5.25v because that score is telling you is that the device can take 5v minus 5 percent of 5v = 4.75 volts  OR  5v and 5 percent of 5v = 5.25 volts. 

An interesting point to note is all chargers provide a higher voltage than the batteries that they charge.  That’s pretty much how they work.  There has 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’s a 12V battery, but typical 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 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 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 efficiently use a charger that did not come with your smart phone, notebook, camera, tablet, or other device.  Be sure to follow exactly what we said and you should be ready to go!
