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

Every cell phone, laptop, and tablet seem to come with their own charger.  If you’re like me, you have probably compiled a number of chargers over the years.  So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet computer that is not the original manufacturer’s charger which came with the device?

Kinds of Chargers

In this guide, we’ll concentrate on three types of chargers: notebook chargers, micro USB chargers (these are used with phones, tablets, and cameras), and Apple Lightning Connectors.  Although some devices have chargers using a slightly different head or charging cable, these are the most common.

Laptop chargers are fairly unique to the device they include.  However, there may be some generic chargers which boast the ability to be interchanged between laptops.  This always requires changing of the 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 many 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 (depending 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 port, a connector can be used to control the Lightning Connector.

The Plugs Must Be The Same

For a charger for use on another 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 notebook chargers are usually specific to both make and model.  However, the plug fitting firmly is only one part of this equation.

Somewhere on the power brick of the charger you’ll find 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 found at the base of the charger, where it would meet up with the wall.  For the device you are trying 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 in the apparatus, or how much is being”pushed” into the apparatus by the charger.  A phone will usually pull up to approximately 5V, though a notebook can pull up to 25V.  A charger must equal the voltage required by the device. 

Amperage is how quickly power is”pulled” to the apparatus, or how much power is used by the device.  The amount of volts will never change, but the amount of amps that the system 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 which may be pulled by the device.  If a device is paired with a charger that cannot support the amp necessity, it may 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 faster charging (as long as the voltage is equivalent ).  *Site Note: if you have an older device, it may not work with USB ports that use the new Battery Charging Specification.

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

Some devices may have their voltage listed using 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 apparatus 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 equivalent to or greater than the device’s listed amperage).

An interesting thing to note is all chargers supply a higher voltage than the batteries they charge.  That’s pretty much how they work.  There has to be a voltage differential to generate the necessary current flow in the proper way to charge the battery.  When you look at your vehicle, it has a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.

Stay Away From Cheap Knockoff Chargers

The problem with knockoffs, particularly cheap knockoffs, is they often don’t support the energy needs of the apparatus, or are not built to keep a steady flow securely.  Overall, it’s better to stay 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 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.  Make sure you follow exactly what we said and you should be good to go!
