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

Every cell phone, notebook, and tablet seem to come with their own charger.  If you’re 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 computer that isn’t the original manufacturer’s charger which came with the device?

Kinds of Chargers

In this article, we will concentrate on three types of chargers: notebook 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 unique to the device they come with.  However, there may be some generic chargers which boast the ability to be interchanged between laptops.  This always requires changing of this charger”head” and might not be the optimal charging amperage or voltage for 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 different amps.  I’ll 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, including iPads and iPods. For older devices with a 30-pin charge interface, a connector can be used to control the Lightning Connector.

The Plugs Must Be The Same

In order for a charger to be used on another device, it’s essential 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 as far as charging heads, while notebook chargers are usually specific to both make and model.  However, the plug fitting securely is just one part of this equation.

Somewhere on the power brick of the charger you will find a tag with the charger’s voltage (V) and amperage (A).  For laptop 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 bottom of the charger, in which it would meet up with the wall.  For the device you’re 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 into the apparatus, or just how much is being”pushed” to the apparatus by the charger.  A phone will usually pull up to approximately 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 device, or how much electricity is used by the device.  The quantity of volts won’t ever change, but the quantity of amps that the system 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 which may be pulled by 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 unit is paired with a charger that cannot support the amp requirement, it can burn out the power source and kill the apparatus.

So for those who have a modern USB device (smart phone, tabletcomputer, 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 may not work with USB interfaces that employ the newest Battery Charging Specification.

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

Some devices may have their voltage listed with a plus/minus on it like that: 5v +- 5%.  If this is true, you may 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% of 5v = 4.75 volts  OR  5v plus 5% of 5v = 5.25 volts.  So 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 higher than the device’s listed amperage).

An interesting point to note is all chargers supply a higher voltage than the batteries that they charge.  That’s pretty much how they work.  There needs to be a voltage differential to generate the necessary current flow in the proper direction to charge the battery.  When 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 problem with knockoffs, especially cheap knockoffs, is they often don’t support the energy requirements of the apparatus, 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 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, notebook, camera, tabletcomputer, or other device.  Be certain you follow exactly what we said and you should be ready to go!
