Can You Use Any Charger With Any Cell Phone, Notebook, Camera, or Tablet?
Every mobile phone, notebook, and tablet seem to come with their own charger. If you’re like me, you’ve 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 that is not the original manufacturer’s charger that came with the device?
Kinds of Chargers
In this article, we will concentrate on three types of chargers: laptop 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 come with. 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 optimal charging amperage or voltage to your device.
Micro USBs are theoretically designed to be interchangeable, and are standard in most smartphones, Android apparatus, and tablets. Micro USB chargers typically have the exact same voltage, but may draw various amps. I will explain this further later and how to know if the charger is safe to use (depending on its recorded amps and voltage).
For older devices using a 30-pin charge interface, a connector can be used to charge with 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 as far as charging heads, whilst notebook chargers are usually specific to both make and model. However, the plug fitting securely is only 1 part of this equation.
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 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 seen 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 apparatus, or just how much is being”pushed” to the apparatus by the charger. A phone will usually pull up to approximately 5V, while a laptop can pull up to 25V. A charger must equal the voltage required by the device. This is important: drawing too high 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 fast power is”pulled” to the device, or how much electricity is used by the device. The quantity of volts will never change, but the amount 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 will be the maximum amount of amps which can be pulled by the device. If a device is paired with a charger that cannot support the amp necessity, it can burn out the power supply 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 (as long as the voltage is equal). *Website Note: if you have an older device, it might not work with USB interfaces that use 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 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 apparatus can take 5v minus 5 percent of 5v = 4.75 volts OR 5v plus 5 percent of 5v = 5.25 volts. 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 higher than the device’s listed amperage).
An interesting point to note is chargers provide a higher voltage than the batteries that they charge. That is pretty much how they operate. There has to be a voltage differential to produce the necessary current flow in the proper direction to charge the battery. If you look at your vehicle, it has a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.
The issue with knockoffs, especially cheap knockoffs, is that they often don’t support the energy needs of the device, or aren’t 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 assist you. Now you know how to safely and efficiently use a charger that did not include your smart phone, laptop, camera, tabletcomputer, or other device. Be certain to follow exactly what we said and you should be good to go!
