Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet?
Every cell phone, notebook, and tablet seem to come with their own charger. If you are like me, you have probably compiled quite a few chargers through the years. So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet that is not the original manufacturer’s charger which came with the device?
Kinds of Chargers
In this article, we’ll focus on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablet computers, 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 specific to the device they come with. However, there can be some generic chargers that boast the ability to be interchanged between laptops. This always requires changing of the charger”head” and might 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 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 whether 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
In order for a charger to be used on a different device, it’s important 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, while laptop chargers are often specific to both make and model. However, the plug fitting securely is just 1 part of this equation.
Somewhere on 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 the wall. For the device you are trying to control, the voltage and amperage required will be found 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 apparatus, or just how much is being”pushed” to the apparatus by the charger. A phone will usually pull up to approximately 5V, though a notebook can pull up to 25V. A charger must equal the voltage required by the device.
Amperage is how fast power is”pulled” into the device, or how much power is used by the device. The quantity of volts won’t ever change, but the amount of amps that the system pulls may change depending on how hard the unit is working. The number that you locate on the battery that came with your device will be the max amount of amps which can be pulled by the device. The number found on the charger is how many amps can be pulled simultaneously. To be able to exchange chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. If a device is paired with a charger that cannot 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 (as long as the voltage is equivalent ). *Site Note: if you have an older device, it might not work with USB interfaces that use the newest 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 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 plus 5% of 5v = 5.25 volts.
An interesting thing to note is chargers provide a higher voltage than the batteries that they charge. That’s pretty much how they operate. There needs to be a voltage differential to generate the necessary current flow in the correct way to charge the battery. If you look at your car, it’s 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 they frequently don’t support the energy requirements of the apparatus, or are not built to keep a steady flow safely. This can cause damage to the device but can also pose a safety/fire hazard. Overall, it’s better to stick with the charger designed for the device you are 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 effectively use a charger that did not come with your smart phone, laptop, camera, tabletcomputer, or other apparatus. Be certain you follow what we said and you should be ready to go!
