Can You Use Any Charger With Any Cell Phone, Laptop, 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 a number of chargers over the years.  So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet computer that is not the original manufacturer’s charger that came with the device?

Types of Chargers

In this guide, we’ll focus 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 rather unique to the device they include.  However, there can be some generic chargers which boast the capability to be interchanged between laptops.  This always requires changing of this charger”head” and might 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 devices, 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 if the charger is safe to use (depending on its listed amps and voltage).

For older devices with 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 to be used on a different 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 as far as charging heads, whilst notebook chargers are usually specific to both make and model.  However, the plug fitting firmly is only 1 part of the equation.

How Voltage and Amperage Matter

Determined by the power brick of the charger you’ll find a tag 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 base 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 seen 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 device, or how much is being”pushed” into the device by the charger.  A phone will usually pull up to around 5V, though a notebook 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 potentially even start a fire, while too low a voltage will fail to charge the battery.

Amperage is how quickly power is”pulled” into the device, or how much power is used by the device.  The amount of volts will never change, but the quantity 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 are the max 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. If a unit is paired with a charger which can’t support the amp necessity, it may burn out the power source and kill the device.

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

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

Some devices might have their voltage recorded with a plus/minus on it like this: 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 device can take 5v minus 5% of 5v = 4.75 volts  OR  5v and 5% of 5v = 5.25 volts. 

An interesting thing to note is all 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 produce the necessary current flow in the correct direction to charge the battery.  When you look at your car, it’s a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.

Stay Away From Cheap Knockoff Chargers

The issue with knockoffs, especially cheap knockoffs, is they frequently don’t support the power needs of the device, or are not built to maintain a steady flow securely.  Overall, it’s best 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 help you.  Now you know how to safely and efficiently use a charger that did not come with your smart phone, laptop, camera, tablet, or other device.  Make sure you follow what we said and you should be good to go!
