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’ve probably compiled a number of 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 that came with the device?

Kinds of Chargers

In this guide, we’ll concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablets, 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 rather 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 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 using a 30-pin charge port, 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 important that the plug  of the charger (the”head”) fit securely into the charging port of the unit.  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 firmly is just one part of this equation.

How Voltage and Amperage Matter

Somewhere on the power brick of the charger you will get a tag with the charger’s voltage (V) and amperage (A).  For other types of chargers, like a smartphone charger, this information is usually located at the bottom of the charger, where 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 just how much is being”pushed” into the apparatus 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 required by the device.  This is important: drawing too high of a voltage could short out the device and possibly even begin a fire, while too low a voltage will fail to charge the battery.

Amperage is how quickly power is”pulled” to the apparatus, or how much power 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 will be the maximum amount of amps that may be pulled from the device.  The number found on the charger is how many amps can be pulled at once. To be able to swap chargers, the amp number on the charger must equal or exceed the amp number listed on the device’s battery. If a unit is paired with a charger that cannot support the amp necessity, it can burn out the power source and kill the apparatus.

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 may not work with USB interfaces that employ the new Battery Charging Specification.

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

Some devices may have their voltage recorded using a plus/minus on it like this: 5v +- 5%.  If this is true, you may use a charger rated at 4.75 to 5.25v because that rating is telling you is that the device can take 5v minus 5 percent of 5v = 4.75 volts  OR  5v and 5% of 5v = 5.25 volts.  So this means anything between 4.75 t0 5.25v is safe to use (so long as the amperage of the charger is equivalent to or greater than the device’s listed amperage).

An interesting thing to note is chargers provide a higher voltage than the batteries they charge.  That’s pretty much how they operate.  There has to be a voltage differential to generate the necessary current flow in the correct direction 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.

The problem with knockoffs, especially cheap knockoffs, is they often don’t support the energy needs of the apparatus, or aren’t built to maintain a steady flow securely.  Overall, it’s better to stay 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 assist you.  Now you know how to safely and efficiently use a charger that did not include your smart phone, notebook, camera, tabletcomputer, or other apparatus.  Be sure to follow exactly what we said and you should be good to go!
