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 have probably compiled a number of 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 guide, we’ll concentrate on three types of chargers: notebook chargers, micro USB chargers (these are used with phones, tablet computers, and cameras), and Apple Lightning Connectors.  Although some devices have chargers using 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 capability to be interchanged between notebooks.  This always requires changing of this charger”head” and may not be the best charging amperage or voltage to your device.

Micro USBs are theoretically designed to be interchangeable, and are standard in most smartphones, Android apparatus, and tablets.  Micro USB chargers typically have the exact same voltage, but may draw different amps.  I will explain this further later and how to know whether the charger is safe to use (based on its recorded amps and voltage).

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

The Plugs Must Be The Same

In order for a charger for use on another device, it’s important that the plug  of the charger (the”head”) fit securely into the charging port of the device.  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 only 1 part of the equation.

How Voltage and Amperage Matter

Somewhere on the power brick of the charger you will get 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, in which it would meet the wall.  For the device you’re 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 in the device, or how much is being”pushed” into the apparatus by the charger.  A phone will usually pull up to approximately 5V, while a laptop can pull up to 25V.  A charger must equal the voltage needed by the device. 

Amperage is how fast power is”pulled” into the apparatus, or how much electricity is used by the device.  The quantity 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 find on the battery that came with your device are the maximum amount of amps that may be pulled from the device.  In order to swap chargers, the amp number on the charger must equal or exceed the amp number recorded 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 supply and kill the device.

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 faster charging (so long as the voltage is equal).  *Site Note: if you have an older device, it might not work with USB ports that employ the newest Battery Charging Specification.

If The Micro USB  Charger’s Voltage Is Not 5v…

Some devices might have their voltage recorded using a plus/minus on it like that: 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 plus 5 percent of 5v = 5.25 volts. 

An interesting point to note is all chargers provide 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.  When you look at your car, it has a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.

The problem with knockoffs, particularly cheap knockoffs, is that they frequently don’t support the energy requirements of the apparatus, or aren’t built to keep a steady flow securely.  This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s best to stay with the charger made 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 effectively use a charger that did not include your smart phone, laptop, camera, tabletcomputer, or other device.  Be sure to follow exactly what we said and you should be ready to go!
