Can You Use Any Charger With Any Mobile Phone, Laptop, Camera, or Tablet?
Every cell phone, laptop, and tablet appear to come with their own charger. If you are like me, you’ve probably compiled quite a few 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 which came with the device?
Types of Chargers
In this article, we will focus 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 with a slightly different head or charging cable, these are the most common.
Laptop chargers are rather specific to the device they include. However, there can be some generic chargers which boast the ability to be interchanged between notebooks. This always requires changing of the charger”head” and might not be the best 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 various amps. I will explain this further later and how to know if the charger is safe to use (based on its listed amps and voltage).
For older devices using a 30-pin charge port, a connector can be used to control the Lightning Connector.
In order 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 unit. Micro USBs are the same across the board as far as charging heads, while laptop chargers are usually specific to both make and model. However, the plug fitting securely is just one part of this equation.
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 bottom of the charger, in which it would meet up with the wall. For the device you are attempting to charge, 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 apparatus, or how much is being”pushed” to the device by the charger. A phone will usually pull up to approximately 5V, while a notebook can pull up to 25V. A charger must equal the voltage needed by the device.
Amperage is how quickly power is”pulled” to the device, or how much power is used by the device. The quantity of volts won’t ever change, but the quantity of amps that the device pulls may change based on how hard the device is working. The number that you locate on the battery that came with your device will be the maximum amount of amps that may be pulled from the device. If a unit is paired with a charger which can’t support the amp necessity, it can 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 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 use the new Battery Charging Specification.
If The Micro USB Charger’s Voltage Is Not 5v…
Some devices might have their voltage listed with a plus/minus on it like that: 5v +- 5%. If this is the case, you can 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 plus 5% of 5v = 5.25 volts.
An interesting thing to note is chargers provide a higher voltage than the batteries they charge. That’s pretty much how they operate. There needs 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 typical alternators provide 13.8 to 14.4V charging voltage to the battery.
The issue with knockoffs, particularly cheap knockoffs, is that they frequently don’t support the power needs of the device, or aren’t built to maintain a steady flow safely. This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s best to stay with the charger made for the device you are 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 come with your smart phone, notebook, camera, tablet, or other device. Be sure you follow what we said and you should be ready to go!
