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

Every mobile phone, laptop, and tablet appear 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, notebook, camera, or tablet computer that isn’t the original manufacturer’s charger which came with the device?

Types of Chargers

In this article, we will concentrate on three types of chargers: notebook chargers, micro USB chargers (these are used with phones, tablets, and cameras), and Apple Lightning Connectors.  While 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 that boast the capability to be interchanged between notebooks.  This always requires changing of this charger”head” and may 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 devices, 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 if the charger is safe to use (depending on its listed amps and voltage).

For older devices with a 30-pin charge port, a connector can be used to charge with the Lightning Connector.

For a charger for use on a different device, it’s essential that the plug  of the charger (the”head”) fit snugly to the charging port of the unit.  Micro USBs are the same across the board so far as charging heads, while notebook chargers are often specific to both make and model.  However, the plug fitting firmly is only 1 part of this equation.

How Voltage and Amperage Matter

Determined by the power brick of the charger you will get a tag with the charger’s voltage (V) and amperage (A).  For laptop chargers, this charging brick is often halfway down the charger and typically looks 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 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 manufacturer’s website.

Voltage is how much power the charger will draw into the device, or just how much is being”pushed” to the device 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.  This is important: drawing too high of a voltage could short out the device and possibly even start a fire, while too low a voltage will fail to charge the battery.

Amperage is how quickly power is”pulled” to the device, or how much electricity is used by the device.  The amount of volts won’t ever change, but the amount of amps that the system 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 which can be pulled from the device.  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 which can’t support the amp necessity, it may burn out the power supply and kill the device.

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 quicker charging (so long as the voltage is equivalent ).  *Website Note: if you have an older device, it might not work with USB ports that employ the new Battery Charging Specification.

If The Micro USB  Charger’s Voltage Is Not 5v…

Some devices may have their voltage recorded 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 device can take 5v minus 5% 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 point to note is chargers supply a higher voltage than the batteries they charge.  That is pretty much how they work.  There needs 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’s a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.

The problem with knockoffs, particularly cheap knockoffs, is they frequently don’t support the energy needs of the device, or are not built to maintain a steady flow safely.  This can result in damage to the device but can also pose a safety/fire hazard. Overall, it’s better to stay with the charger designed 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 effectively use a charger that did not come with your smart phone, notebook, camera, tablet, or other device.  Be sure to follow exactly what we said and you should be ready to go!
