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

Every cell phone, laptop, and tablet appear to come with their own charger.  If you’re like me, you have probably compiled quite a few chargers through the years.  So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet computer that isn’t the original manufacturer’s charger which came with the device?

Kinds of Chargers

In this guide, we will focus 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 using a slightly different head or charging cable, these are the most frequent.

Laptop chargers are fairly specific to the device they come with.  However, there can be some generic chargers which boast the capability 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 whether the charger is safe to use (depending 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.

In order for a charger to be used on a different device, it’s essential that the plug  of the charger (the”head”) fit snugly to the charging port of the device.  Micro USBs are the same across the board so far as charging heads, while laptop chargers are usually specific to both make and model.  However, the plug fitting securely is only 1 part of the equation.

Determined by the power brick of the charger you will get a label 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 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 company’s website.

Voltage is how much power the charger will draw in the apparatus, or just how much is being”pushed” to the apparatus 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 required by the device.  This is important: drawing too high a voltage could short out the device and potentially even begin a fire, while too low a voltage will fail to charge the battery.

Amperage is how fast power is”pulled” into the device, 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 find on the battery that came with your device will be 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 can burn out the power supply and kill the apparatus.

So if you have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (as long as the voltage is equal).  *Site Note: if you have an older device, it may not work with USB ports that use the newest 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 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.  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 greater than the device’s listed amperage).

An interesting point to note is all chargers supply a higher voltage than the batteries they charge.  That’s pretty much how they work.  There needs 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 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 that they frequently don’t support the energy needs of the device, or aren’t built to keep a steady flow safely.  This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s better to stick with the charger made for the device you’re using.

Now You Understand 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, tabletcomputer, or other device.  Make sure you follow exactly what we said and you should be ready to go!
